The clinical consequences were not severe in most cases, but deaths have been reported after overdoses involving topiramate.
  • Topiramate overdose has resulted in severe metabolic acidosis [].
  • A patient who ingested a dose of topiramate between 96 and 110 g was admitted to a hospital with a coma lasting 20 to 24 hours followed by full recovery after 3 to 4 days.
  • In acute topiramate overdose, if the ingestion is recent, the stomach should be emptied immediately by lavage or by induction of emesis. Activated charcoal has been shown to adsorb topiramate . Hemodialysis is an effective means of removing topiramate from the body.
  • Topiramate, USP is a sulfamate-substituted monosaccharide. Topiramate capsules (sprinkle) are available as 15 mg and 25 mg sprinkle capsules for oral administration as whole capsules or opened and sprinkled onto soft food.
  • Topiramate, USP is a white crystalline powder with a bitter taste.

It is freely soluble in acetone, chloroform, dimethylsulfoxide, and ethanol. The solubility in water is 9.8 mg/mL. Its saturated solution has a pH of 6.3. Topiramate, USP is designated chemically as 2,3:4,5-Di--isopropylidene-u03b2-D-fructopyranose sulfamate and has the following structural formula:
  • CHNOS M.W. 339.36

  • No data
  • Carcinogenesis
  • An increase in urinary bladder tumors was observed in mice given topiramate (0, 20, 75, and 300 mg/kg/day) in the diet for 21 months. The increase in the incidence of bladder tumors in males and females receiving 300 mg/kg/day was primarily due to the increased occurrence of a smooth muscle tumor considered histomorphologically unique to mice. Plasma exposures in mice receiving 300 mg/kg/day were less than or equal to steady-state exposures in patients receiving topiramate monotherapy at the maximum recommended human dose (MRHD) for epilepsy (400 mg), and 1.5 to 2 times steady-state topiramate exposures in patients receiving 400 mg of topiramate plus phenytoin. The relevance of this finding to human carcinogenic risk is uncertain. 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/m basis).
  • Mutagenesis
  • Topiramate did not demonstrate genotoxic potential when tested in a battery of and assays. Topiramate was not mutagenic in the Ames test or the mouse lymphoma assay; it did not increase unscheduled DNA synthesis in rat hepatocytes ; and it did not increase chromosomal aberrations in human lymphocytes or in rat bone marrow .
  • Impairment of Fertility
  • 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/m basis).
  • The studies described in the following sections were conducted using topiramate tablets.
  • No data
  • Advise the patient to read the FDA-approved patient labeling (Medication Guide).
  • Eye Disorders
  • Instruct patients taking topiramate to seek immediate medical attention if they experience blurred vision, visual disturbances, or periorbital pain [].
  • Oligohidrosis and Hyperthermia
  • Closely monitor topiramate-treated patients, especially pediatric patients, for evidence of decreased sweating and increased body temperature, especially in hot weather. Counsel patients to contact their healthcare professionals immediately if they develop a high or persistent fever, or decreased sweating [].
  • Metabolic Acidosis
  • 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 [].
  • Suicidal Behavior and Ideation
  • Counsel patients, their caregivers, and families that AEDs, including topiramate, may increase the risk of suicidal thoughts and behavior, and advise of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior or the emergence of suicidal thoughts, or behavior or thoughts about self-harm. Instruct patients to immediately report behaviors of concern to their healthcare providers [].
  • Interference with Cognitive and Motor Performance
  • Warn patients about the potential for somnolence, dizziness, confusion, difficulty concentrating, or visual effects, and advise patients not to drive or operate machinery until they have gained sufficient experience on topiramate to gauge whether it adversely affects their mental performance, motor performance, and/or vision [].
  • Even when taking topiramate or other anticonvulsants, some patients with epilepsy will continue to have unpredictable seizures. Therefore, advise all patients taking topiramate for epilepsy to exercise appropriate caution when engaging in any activities where loss of consciousness could result in serious danger to themselves or those around them (including swimming, driving a car, climbing in high places, etc.). Some patients with refractory epilepsy will need to avoid such activities altogether. Discuss the appropriate level of caution with patients, before patients with epilepsy engage in such activities.
  • Fetal Toxicity
  • Inform pregnant women and women of childbearing potential that use of topiramate during pregnancy can cause fetal harm, including an increased risk for cleft lip and/or cleft palate (oral clefts), which occur early in pregnancy before many women know they are pregnant. Also inform patients that infants exposed to topiramate monotherapy may be SGA []. There may also be risks to the fetus from chronic metabolic acidosis with use of topiramate during pregnancy []. When appropriate, counsel pregnant women and women of childbearing potential about alternative therapeutic options.
  • Advise women of childbearing potential who are not planning a pregnancy to use effective contraception while using topiramate, keeping in mind that there is a potential for decreased contraceptive efficacy when using estrogen-containing birth control with topiramate [].
  • Encourage pregnant women using topiramate, to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry. The registry is collecting information about the safety of antiepileptic drugs during pregnancy [].
  • Hyperammonemia and Encephalopathy
  • Warn patients about the possible development of hyperammonemia with or without encephalopathy. Although hyperammonemia may be asymptomatic, clinical symptoms of hyperammonemic encephalopathy often include acute alterations in level of consciousness and/or cognitive function with lethargy and/or vomiting. This hyperammonemia and encephalopathy can develop with topiramate treatment alone or with topiramate treatment with concomitant valproic acid (VPA).
  • Instruct patients to contact their physician if they develop unexplained lethargy, vomiting, or changes in mental status [n n ].
  • Kidney Stones
  • Instruct patients, particularly those with predisposing factors, to maintain an adequate fluid intake in order to minimize the risk of kidney stone formation [n n ].
  • Instructions for a Missing Dose
  • Instruct patients that if they miss a single dose of topiramate, it should be taken as soon as possible. However, if a patient is within 6 hours of taking the next scheduled dose, tell the patient to wait until then to take the usual dose of topiramate, and to skip the missed dose. Tell patients that they should not take a double dose in the event of a missed dose. Advise patients to contact their healthcare provider if they have missed more than one dose.
