Topiramate is a white crystalline powder with a bitter taste. Keep a list of them to show your healthcare provider and pharmacist each time you get a new medicine. Tell patients that they should not take a double dose in the event of a missed dose. . No alterations of 9-hydroxyrisperidone levels were observed. Pediatric patients on adjunctive treatment exhibited a higher oral clearance (L/h) of topiramate compared to patients on monotherapy, presumably because of increased clearance from concomitant enzyme-inducing antiepileptic drugs. Clinical symptoms of hyperammonemic encephalopathy often include acute alterations in level of consciousness and/or cognitive function with lethargy and/or vomiting. TOPAMAX can cause fetal harm when administered to a pregnant woman. In general . include protected health information. This metabolic acidosis is caused by renal bicarbonate loss due to carbonic anhydrase inhibition by TOPAMAX. In a single randomized, double-blind, placebo-controlled investigational trial, the efficacy, safety, and tolerability of topiramate oral liquid and sprinkle formulations as an adjunct to concurrent antiepileptic drug therapy in pediatric patients 1 to 24 months of age with refractory partial-onset seizures were assessed. In a pharmacokinetic interaction study in healthy volunteers with a concomitantly administered combination oral contraceptive product containing 1 mg norethindrone (NET) plus 35 mcg ethinyl estradiol (EE), TOPAMAX, given in the absence of other medications at doses of 50 to 200 mg/day, was not associated with statistically significant changes in mean exposure (AUC) to either component of the oral contraceptive. TOPAMAX is not approved for treatment of epilepsy in pediatric patients less than 2 years old [see Use In Specific Populations]. Counsel patients to contact their healthcare professionals immediately if they develop a high or persistent fever, or decreased sweating [see WARNINGS AND PRECAUTIONS]. It may harm them. Stay alert to changes in your mood or symptoms. The effect of TOPAMAX on growth and bone-related sequelae has not been systematically investigated in long-term, placebo-controlled trials. No adverse effects on male or female fertility were observed in rats administered topiramate orally at doses up to 100 mg/kg/day (2.5 times the MRHD for epilepsy and 10 times the MRHD for migraine on a mg/m2 basis) prior to and during mating and early pregnancy. You should not stop taking Topamax suddenly unless your doctor has told you to stop. Six metabolites have been identified in humans, none of which constitutes more than 5% of an administered dose. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records.

In patients, the pharmacokinetics of lithium were unaffected during treatment with topiramate at doses of 200 mg/day; however, there was an observed increase in systemic exposure of lithium (27% for Cmax and 26% for AUC) following topiramate doses up to 600 mg/day [see DRUG INTERACTIONS]. Multiple dosing of topiramate (200 mg/day) in 34 healthy volunteers (17 males, 17 females) did not affect the pharmacokinetics of propranolol following daily 160 mg doses. drugs a-z list However, if you are within 6 hours of taking your next scheduled dose, wait until then to take your usual dose of TOPAMAX, and skip the missed dose. Description and Brand Names. Topiramate is a sulfamate-substituted monosaccharide. Hydration is recommended to reduce new stone formation. If you take too much TOPAMAX, call your healthcare professional or poison control center right away or go to an emergency room. Information about the North American Drug Pregnancy Registry can be found at http://www.aedpregnancyregistry.org/. In Study 11, a total of 469 patients (416 females, 53 males), ranging in age from 13 to 70 years, were randomized and provided efficacy data. Rapid titration rate and higher initial dose were associated with higher incidences of cognitiverelated dysfunction. Notable changes (increases and decreases) from baseline in systolic blood pressure, diastolic blood pressure, and pulse were observed occurred more commonly in pediatric patients treated with topiramate compared to pediatric patients treated with placebo [see CLINICAL PHARMACOLOGY]. (Studies 11 and 12 for Adults and Adolescents). All rights reserved. Tamsulosin may cause serious side effects. Topamax is a prescription medicine used to treat the symptoms of migraine headaches, seizures and Lennox-Gastaut Syndrome. What is the most important information I should know about TOPAMAX? The clinical significance of this change is unknown. Drug class: carbonic anhydrase inhibitor anticonvulsants. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. In the four multicenter, randomized, double-blind, placebo-controlled, parallel group migraine clinical trials for the preventive treatment of migraine (which included 35 pediatric patients 12 to 15 years of age), most adverse reactions occurred more frequently during the titration period than during the maintenance period. What are the possible side effects of TOPAMAX? Your reactions could be impaired. However, clinical studies of topiramate did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently than younger subjects. This medication is also used to prevent migraine headaches and decrease how often you get them. information submitted for this request. For more information, ask your doctor or pharmacist. To provide you with the most relevant and helpful information, and understand which You may also report side effects to Janssen Pharmaceuticals, Inc. at 1-800-JANSSEN (1-800-526-7736). After titration, patients entered an 8-week stabilization period. In this open-label, uncontrolled study, the mortality was 37 deaths/1000 patient years. Topiramate treatment also produced a dose-related increase in the percentage of patients who had a shift from normal at baseline to high/increased (above the normal reference range) in total eosinophil count at the end of treatment. TOPAMAX is indicated as adjunctive therapy for the treatment of partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome in patients 2 years of age and older. Adults and Pediatric Patients 10 Years of Age and Older. The effectiveness of TOPAMAX as an adjunctive treatment for pediatric patients 2 to 16 years of age with partial-onset seizures was established in a multicenter, randomized, double-blind, placebo-controlled trial (Study 8), comparing TOPAMAX and placebo in patients with a history of partial-onset seizures, with or without secondarily generalized seizures (see Table 12). Warn patients about the potential significant risk for metabolic acidosis that may be asymptomatic and may be associated with adverse effects on kidneys (e.g., kidney stones, nephrocalcinosis), bones (e.g., osteoporosis, osteomalacia, and/or rickets in children), and growth (e.g., growth delay/retardation) in pediatric patients, and on the fetus [see WARNINGS AND PRECAUTIONS, Use In Specific Populations]. Included as part of the "PRECAUTIONS" Section. Topiramate Class. A 15% decrease in the AUC,ss of pioglitazone with no alteration in Cmax,ss was observed. In controlled clinical trials in adults, 11% of patients receiving TOPAMAX 200 to 400 mg/day as adjunctive therapy discontinued due to adverse reactions. No evidence of carcinogenicity was seen in rats following oral administration of topiramate for 2 years at doses up to 120 mg/kg/day (approximately 3 times the MRHD for epilepsy and 12 times the MRHD for migraine on a mg/m2 basis). A population pharmacokinetic model was developed on the basis of pharmacokinetic data from relevant topiramate clinical studies. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. Topiramate is most soluble in alkaline solutions containing sodium hydroxide or sodium phosphate and having a pH of 9 to 10. TOPAMAX is indicated for the preventive treatment of migraine in patients 12 years of age and older. If the target dose could not be achieved, patients were maintained on the maximum tolerated dose. Carbonic anhydrase inhibitors can promote stone formation by reducing urinary citrate excretion and by increasing urinary pH [see Metabolic Acidosis]. Fifty-eight percent of patients achieved the maximal dose of 400 mg/day for >2 weeks, and patients who did not tolerate 150 mg/day were discontinued. Sign up for free, and stay up to date on research advancements, health tips and current health topics, like COVID-19, plus expertise on managing health. Ask your doctor about any risks. The most common side effects of TOPAMAX include: Tell your healthcare provider about any side effect that bothers you or that does not go away. Active drug was titrated beginning at 1 mg/kg/day for a week; the dose was then increased to 3 mg/kg/day for one week, then to 6 mg/kg/day. Safety and effectiveness in patients below the age of 2 years have not been established for the adjunctive therapy treatment of partial-onset seizures, primary generalized tonic-clonic seizures, or seizures associated with Lennox-Gastaut syndrome. 6. The clinical significance of these various changes in vital signs has not been clearly established. The adverse reactions associated with discontinuing therapy in the TOPAMAX-treated patients included paresthesia (7%), fatigue (4%), nausea (4%), difficulty with concentration/attention (3%), insomnia (3%), anorexia (2%), and dizziness (2%). The clinical significance of these findings is not known. Multiple dosing of topiramate (100 mg every 12 hours) in 24 healthy volunteers (14 males, 10 females) did not affect the pharmacokinetics of single-dose sumatriptan either orally (100 mg) or subcutaneously (6 mg). Metabolic acidosis may have harmful effects on your baby. TOPAMAX treatment that causes metabolic acidosis during pregnancy can possibly produce adverse effects on the fetus and might also cause metabolic acidosis in the neonate from possible transfer of topiramate to the fetus [see Fetal Toxicity, Use In Specific Populations]. Advise women of childbearing potential who are not planning a pregnancy to use effective contraception while using TOPAMAX, keeping in mind that there is a potential for decreased contraceptive efficacy when using estrogen-containing birth control with topiramate [see DRUG INTERACTIONS]. Medically reviewed by Sophia Entringer, PharmD. (topiramate capsules) A drug-drug interaction study conducted in patients with type 2 diabetes evaluated the steady-state pharmacokinetics of glyburide (5 mg/day) alone and concomitantly with topiramate (150 mg/day). This may help increase the flow of urine or decrease the symptoms. Do not stop using this medication before surgery unless your surgeon tells you to. Concomitant administration of valproic acid and TOPAMAX has been associated with hypothermia and hyperammonemia with and without encephalopathy. Evidence of maternal toxicity (decreased body weight gain, clinical signs, and/or mortality) was seen at 35 mg/kg/day and above. Continue reading, You can usually stay on Topamax (topiramate) to help prevent your migraine headaches as long as the treatment is needed and remains safe for you. [5] This high clearance (compared to 20 to 30 mL/min total oral clearance in healthy adults) will remove a clinically significant amount of topiramate from the patient over the hemodialysis treatment period [see DOSAGE AND ADMINISTRATION, Use In Specific Populations]. If the decision is made to continue patients on TOPAMAX in the face of persistent acidosis, alkali treatment should be considered. Any AED therapy used for temporary or emergency purposes was discontinued prior to randomization. Safety and effectiveness in patients below the age of 2 years have not been established for the monotherapy treatment of epilepsy. A drug interaction study conducted in healthy volunteers evaluated the steady-state pharmacokinetics of metformin (500 mg every 12 hours) and topiramate in plasma when metformin was given alone and when metformin and topiramate (100 mg every 12 hours) were given simultaneously. The elderly subject population had reduced renal function (creatinine clearance [-20%]) compared to young adults. In open-label, uncontrolled experience, increasing impairment of adaptive behavior was documented in behavioral testing over time in this population. A drug interaction study conducted in healthy volunteers evaluated the steady-state pharmacokinetics of hydrochlorothiazide (HCTZ) (25 mg every 24 hours) and topiramate (96 mg every 12 hours) when administered alone and concomitantly. Discuss the appropriate level of caution with patients, before patients with epilepsy engage in such activities. The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Even when taking TOPAMAX or other anticonvulsants, some patients with epilepsy will continue to have unpredictable seizures. You should not use this medication if you are allergic to tamsulosin. In pediatric epilepsy trials (adjunctive and monotherapy), the incidence of cognitive/neuropsychiatric adverse reactions was generally lower than that observed in adults. Some of the cases were reported after exposure to elevated environmental temperatures. Table 9 shows adverse reactions from the pediatric trial (Study 13 [see Clinical Studies]) in which 103 pediatric patients were treated with placebo or 50 mg or 100 mg of TOPAMAX, and three predominantly adult trials in which 49 pediatric patients (12 to 17 years of age) were treated with placebo or 50 mg, 100 mg or 200 mg of TOPAMAX. a blockage of fluid in the eye causing increased pressure in the eye (secondary angle closure. The Cambridge Neuropsychological Test Automated Battery (CANTAB) was administered to adolescents (12 to 17 years) to assess the effects of topiramate on cognitive function at baseline and at the end of the Study 13 [see Clinical Studies]. Topamax is also used to prevent migraine headaches in adults and teenagers who are at least 12 years old. In rats, given probenecid to inhibit tubular reabsorption, along with topiramate, a significant increase in renal clearance of topiramate was observed. The incidence of these abnormal shifts was 6 % for placebo, 10% for 5 mg/kg/day, 9% for 15 mg/kg/day, 14% for 25 mg/kg/day, and 11% for any topiramate dose. What are the new treatment options for migraines? Advertising revenue supports our not-for-profit mission. Antiepileptic drugs (AEDs), including TOPAMAX, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. The clinical relevance of this observation has not been established. In another study, exposure to EE was statistically significantly decreased at doses of 200, 400, and 800 mg/day (18%, 21%, and 30%, respectively) when given as adjunctive therapy in patients taking valproic acid. TOPAMAX overdose has resulted in severe metabolic acidosis [see WARNINGS AND PRECAUTIONS]. Topiramate is designated chemically as 2,3:4,5- Di-O-isopropylidene--D-fructopyranose sulfamate and has the following structural formula: TOPAMAX Tablets contain the following inactive ingredients: carnauba wax, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, pregelatinized starch, purified water, sodium starch glycolate, synthetic iron oxide, and titanium dioxide. If you cannot swallow a Topamax Sprinkle Capsule whole, open the capsule and sprinkle the medicine into a spoonful of applesauce or other soft food. Study 1 was conducted in 487 patients diagnosed with epilepsy (6 to 83 years of age) who had 1 or 2 well-documented seizures during the 3-month retrospective baseline phase who then entered the study and received TOPAMAX 25 mg/day for 7 days in an open-label fashion. Especially tell your healthcare provider if you take: Ask your healthcare provider if you are not sure if your medicine is listed above. The lowest dose tested, which was associated with increased malformations, is less than the maximum recommended human dose (MRHD) for epilepsy (400 mg/day) or migraine (100 mg/day) on a body surface area (mg/m2) basis. The sprinkle formulation is bioequivalent to the immediate-release tablet formulation and, therefore, may be substituted as a therapeutic equivalent. Warn patients about the possible development of hyperammonemia with or without encephalopathy. Topamax can increase body temperature and decrease sweating, which may lead to life-threatening dehydration. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated. Reflecting the primary renal elimination of topiramate, topiramate plasma and renal clearance were reduced 21% and 19%, respectively, in elderly subjects, compared to young adults. Kidney stones have also been reported in pediatric patients taking TOPAMAX for epilepsy or migraine. The most common side effects of Topamaxinclude: Tell the doctor if you have any side effect that bothers you or that does not go away. The clinical significance of this change is unknown. Dosage Dosage can depend on many factors but typically it is 0.4 mg. You should, however, follow your doctor's specific dosing instructions. US Brand Name Flomax Descriptions Tamsulosin is used to treat men who have symptoms of an enlarged prostate gland, which is also known as benign enlargement of the prostate (benign prostatic hyperplasia or BPH). When topiramate (0, 30, 90, and 300 mg/kg/day) was administered orally to rats during the juvenile period of development (postnatal days 12 to 50), bone growth plate thickness was reduced in males at the highest dose. Copyright 1996-2023 Cerner Multum, Inc. This rate appeared to increase at dosages above 400 mg/day. Avoid driving or hazardous activity until you know how this medicine will affect you. The study enrolled 103 patients (40 male, 63 female) 12 to 17 years of age with episodic migraine headaches with or without aura. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. This content does not have an English version. Topiramate will not treat a migraine headache once it occurs. However, tamsulosin will not shrink the prostate. In the sixth study (Study 7), the 25 or 50 mg/day initial doses of topiramate were followed by respective weekly increments of 25 or 50 mg/day until the target dose of 200 mg/day was reached. There is evidence of renal tubular reabsorption of topiramate. Revised: Jun 2020. Manufactured by: Janssen Ortho LLC, Guarabo, Puerto Rico 00778. Topiramate did not demonstrate genotoxic potential when tested in a battery of in vitro and in vivo assays. The gelatin capsules are white and clear and are marked as follows: TOPAMAX Tablets should be stored in tightly-closed containers at controlled room temperature (59 to 86F, 15 to 30C). Food and drink that may interact with this drug include: Taking tamsulosin with any food may decrease its effectiveness by 30 percent, according to the FDA . Open-label extension phases of 3 studies enabled evaluation of long-term safety for up to 6 months after the end of the double-blind phase. Tamsulosin Class. If you stop using tamsulosin for several days in a row, do not start it again without your doctor's advice. Carbonic anhydrase inhibitor anticonvulsants. . How can I watch for early symptoms of suicidal thoughts and actions? Advise patients to contact their healthcare provider if they have missed more than one dose. The risk for hyperammonemia with topiramate appears dose-related. Benign enlargement of the prostate is a problem that can occur in men as they get older. In pooled, controlled clinical trials in pediatric patients (2 to 15 years of age) with partial-onset seizures, primary generalized tonic-clonic seizures, or Lennox-Gastaut syndrome, 98 patients received adjunctive therapy with TOPAMAX at dosages of 5 to 9 mg/kg/day (recommended dose range) and 101 patients received placebo. Table 5: Adverse Reactions in the High Dose Group As Compared to the Low Dose Group, in Monotherapy Epilepsy Trial (Study 1) in Adult and Pediatric Patients. Do not give TOPAMAX to other people, even if they have the same symptoms that you have. vision problems, blurred vision, eye pain or redness, sudden vision loss (can be permanent if not treated quickly); confusion, problems with thinking or memory, trouble concentrating, problems with speech; dehydration symptoms--decreased sweating, high fever, hot and dry skin; signs of a kidney stone--severe pain in your side or lower back, painful or difficult urination; signs of too much acid in your blood--irregular heartbeats, feeling tired, loss of appetite, trouble thinking, feeling short of breath; or. The mean migraine headache frequency rate at baseline was approximately 5.5 migraine headaches/28 days and was similar across treatment groups. A drug interaction study conducted in healthy volunteers evaluated the steady-state pharmacokinetics of topiramate and pioglitazone when administered alone and concomitantly.

Tell your doctor right away if you become pregnant. Although not studied, topiramate treatment or an interaction of concomitant topiramate and valproic acid treatment may exacerbate existing defects or unmask deficiencies in susceptible persons. The effects of these interactions on mean plasma AUCs are summarized in Table 10. Generic name: topiramate [toe-PYRE-a-mate] Tell your doctor about all your current medicines. Pharmacokinetics of topiramate were evaluated in patients age 2 to <16 years. In Table 10, the second column (AED concentration) describes what happens to the concentration of the co-administered AED listed in the first column when topiramate is added. Changes (increases and decreases) from baseline in vital signs (systolic blood pressure-SBP, diastolic blood pressure-DBP, pulse) occurred more frequently in pediatric patients (6 to 17 years) treated with various daily doses of topiramate (50 mg, 100 mg, 200 mg, 2 to 3 mg/kg) than in patients treated with placebo in controlled trials for the preventive treatment of migraine. If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant. The numbers of patients randomized to each dose and the actual mean and median doses in the stabilization period are shown in Table 11. It is not possible to know whether this mortality rate is related to topiramate treatment, because the background mortality rate for a similar, significantly refractory, young pediatric population (1-24 months) with partial epilepsy is not known. Call your doctor right away if you have a sudden decrease in vision. This can cause problems in urinating, such as a need to urinate often, a weak stream when urinating, or a feeling of not being able to empty the bladder completely. Based upon tolerability and clinical response, additional titration to a higher dose (up to the maximum maintenance dose) can be attempted at 25-50 mg/day weekly increments. 2, gelatin, red iron oxide, titanium dioxide, yellow iron oxide and trace amounts of antifoam DC 1510, industrial methylated spirit, lecithin, n-butyl alcohol, dehydrated alcohol, isopropyl alcohol, butyl alcohol, propylene glycol, ammonium, potassium hydroxide and shellac. Hemodialysis is an effective means of removing topiramate from the body. Breastfed babies may be sleepy or have diarrhea. The differences between the TOPAMAX 100 and 200 mg/day groups versus placebo were similar and statistically significant (p=0.008 and p <0.001, respectively). TOPAMAX is not indicated for partial-onset seizures in pediatric patients less than 2 years of age. Topiramate is cleared by hemodialysis at a rate that is 4 to 6 times greater than in a normal individual. Topamax is an antiepileptic drug, prescribed to control both the mild attacks known as partial seizures and the severe tonic-clonic convulsions known as grand mal seizures. The change in the mean 4-week migraine headache period frequency from baseline to the double-blind phase was -1.4, -2.1, and -2.4 in the TOPAMAX 50, 100, and 200 mg/day groups, respectively, versus -1.1 in the placebo group (see Figure 2). The metabolites are formed via hydroxylation, hydrolysis, and glucuronidation. It is not known if the TOPAMAX that passes into breast milk can cause other serious harm to your baby. Potential interactions between topiramate and standard AEDs were assessed in controlled clinical pharmacokinetic studies in patients with epilepsy. In patients with renal impairment (creatinine clearance less than 70 mL/min/1.73 m2), one-half of the usual adult dose of TOPAMAX is recommended [see Use In Specific Populations, CLINICAL PHARMACOLOGY]. In addition, a 13% and 16% decrease in Cmax,ss and AUC,ss respectively, of the active hydroxy-metabolite was noted as well as a 60% decrease in Cmax,ss and AUC,ss of the active keto-metabolite.
