Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced as a result of the allergy.
All medications you are currently taking, including prescription and over-the-counter (OTC) drugs, natural products, and vitamins. This information will help your doctor and pharmacist assess potential interactions between this medication and other substances you are taking.
* Any existing health problems, as this medication may interact with certain conditions.
To ensure your safety, it is crucial to verify that it is safe to take this medication with all your current medications and health conditions. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
To minimize the risk of seizures, do not abruptly stop taking this medication without first consulting your doctor. If you need to discontinue use, your doctor will guide you on how to gradually stop taking it. Regularly undergo blood tests and other laboratory exams as directed by your doctor.
While taking this medication, avoid consuming alcohol. Additionally, consult your doctor before using marijuana, cannabis, or prescription and over-the-counter drugs that may cause drowsiness.
This medication may increase the risk of developing metabolic acidosis, a condition characterized by an acid imbalance in the blood. This risk is higher in children, individuals with kidney problems, breathing difficulties, or diarrhea. The risk may also be elevated if you take certain medications, undergo surgery, or follow a ketogenic diet. If left untreated, metabolic acidosis can lead to kidney stones, bone problems, or growth issues in children over time.
There is a potential increased risk of bleeding associated with this medication, which can be life-threatening in some cases. Discuss this risk with your doctor.
When taken with valproic acid, this medication can cause hypothermia, leading to fatigue, confusion, or coma. Consult your doctor about this potential interaction.
If the patient is a child, use this medication with caution, as the risk of certain side effects may be higher. In some cases, this medication can affect growth in children and teenagers, making regular growth checks necessary. Discuss this with your doctor.
The effectiveness of birth control pills and other hormone-based contraceptives may be reduced when taking this medication. Use an additional form of birth control, such as condoms, to prevent pregnancy. If you experience changes in your menstrual bleeding pattern while taking hormone-based birth control, consult your doctor.
This medication may harm the unborn baby if taken during pregnancy. If you become pregnant or suspect you are pregnant while taking this medication, contact your doctor immediately. If you are able to become pregnant and do not wish to, use a reliable form of birth control to prevent pregnancy while taking this medication.
If you are breastfeeding, inform your doctor to discuss any potential risks to your baby.
Overdose Information
Overdose Symptoms:
- Convulsions
- Drowsiness
- Speech disturbance
- Blurred vision
- Diplopia (double vision)
- Impaired coordination
- Lethargy
- Stupor
- Hypotension
- Abdominal pain
- Agitation
- Dizziness
- Depression
- Metabolic acidosis
What to Do:
Call 911 or your local poison control center (1-800-222-1222 in the US) immediately. Induce emesis if recently ingested and patient is conscious. Gastric lavage may be indicated. Provide supportive care, maintain airway, monitor vital signs. Hemodialysis is an effective means of removing topiramate from the body.
Drug Interactions
Major Interactions
- Valproic Acid (VPA): Concomitant use may cause hyperammonemia with or without encephalopathy. Monitor ammonia levels.
- Oral Contraceptives: Topiramate can decrease the efficacy of estrogen-containing oral contraceptives, leading to breakthrough bleeding and potential pregnancy. Patients should use alternative or additional birth control methods.
- Carbonic Anhydrase Inhibitors (e.g., Acetazolamide, Zonisamide): Increased risk of metabolic acidosis and kidney stone formation.
Moderate Interactions
- CNS Depressants (e.g., Alcohol, Benzodiazepines, Opioids): Increased risk of CNS depression (drowsiness, dizziness).
- Metformin: Topiramate may decrease metformin exposure. Monitor glycemic control.
- Lithium: Topiramate may decrease lithium levels. Monitor lithium levels.
- Hydrochlorothiazide (HCTZ): HCTZ may increase topiramate levels. Dose adjustment of topiramate may be needed.
- Phenytoin/Carbamazepine: May decrease topiramate levels due to enzyme induction. Topiramate may also increase phenytoin levels.
Minor Interactions
- Digoxin: Topiramate may decrease digoxin levels. Monitor digoxin levels.
- Pioglitazone: Topiramate may decrease pioglitazone exposure. Monitor glycemic control.
Monitoring
Baseline Monitoring
Rationale: To establish baseline for metabolic acidosis risk.
Timing: Before initiation
Rationale: Topiramate is primarily renally eliminated; dose adjustment needed for impairment.
Timing: Before initiation
Rationale: Topiramate can cause weight loss.
Timing: Before initiation
Rationale: To establish baseline for acute angle-closure glaucoma risk.
Timing: Before initiation (especially if history of eye conditions)
Routine Monitoring
Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)
Target: 22-29 mEq/L
Action Threshold: < 20 mEq/L or symptomatic acidosis; consider dose reduction or discontinuation.
Frequency: Periodically (e.g., every 3-6 months)
Target: Stable
Action Threshold: Significant or rapid weight loss; assess nutritional intake.
Frequency: Annually or as clinically indicated (more frequently in elderly or those with risk factors)
Target: Stable
Action Threshold: Significant decline in eGFR; consider dose adjustment.
Frequency: Periodically (especially if on diuretics or with risk factors for kidney stones)
Target: Normal
Action Threshold: Abnormal levels; investigate cause and manage.
Symptom Monitoring
- Cognitive impairment (e.g., difficulty concentrating, memory problems, word-finding difficulties)
- Mood changes (e.g., depression, anxiety, suicidal ideation)
- Vision changes (e.g., blurred vision, eye pain, sudden decrease in vision - signs of acute angle-closure glaucoma)
- Symptoms of metabolic acidosis (e.g., fatigue, anorexia, rapid breathing, cardiac arrhythmias)
- Symptoms of kidney stones (e.g., flank pain, hematuria)
- Paresthesias (tingling sensations)
- Fever, confusion, vomiting (signs of hyperammonemia, especially with valproic acid)
Special Patient Groups
Pregnancy
Topiramate should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. It is associated with an increased risk of major congenital malformations, particularly oral clefts (cleft lip/palate) and hypospadias.
Trimester-Specific Risks:
Lactation
Topiramate is excreted into human milk. The decision to breastfeed should consider the developmental and health benefits of breastfeeding, the motherβs clinical need for topiramate, and any potential adverse effects on the breastfed infant from topiramate or from the underlying maternal condition. Monitor infants for drowsiness, poor feeding, and diarrhea.
Pediatric Use
Dosing is weight-based for epilepsy in children β₯2 years. Monitor for growth, weight changes, and cognitive side effects. Increased risk of metabolic acidosis and kidney stones compared to adults. Behavioral and cognitive side effects may be more pronounced.
Geriatric Use
Start with lower doses and titrate slowly due to potential for decreased renal clearance and increased susceptibility to side effects (e.g., cognitive impairment, metabolic acidosis, kidney stones). Monitor renal function closely.
Clinical Information
Clinical Pearls
- Topiramate sprinkle capsules can be swallowed whole or opened and sprinkled on a spoonful of soft food (e.g., applesauce, pudding) and swallowed immediately without chewing.
- Patients should be advised to drink plenty of fluids to minimize the risk of kidney stone formation.
- Cognitive side effects (e.g., 'topamax fog' or 'topiramate stupor') are common, especially during titration, and can be dose-limiting. Slower titration may help mitigate these.
- Weight loss is a common side effect and can be beneficial for some patients, but should be monitored to prevent excessive loss.
- Patients should be screened for a history of kidney stones or glaucoma before starting topiramate.
- Due to the risk of metabolic acidosis, serum bicarbonate levels should be monitored, especially in pediatric patients and those with renal impairment.
Alternative Therapies
- For Epilepsy: Levetiracetam, Lamotrigine, Valproic Acid, Carbamazepine, Oxcarbazepine, Phenytoin, Gabapentin, Pregabalin.
- For Migraine Prophylaxis: Propranolol, Timolol, Amitriptyline, Valproic Acid, Erenumab, Fremanezumab, Galcanezumab, Eptinezumab, Rimegepant, Atogepant.
