Topiramate can cause increased body temperature and decreased sweating, and these effects may be even greater when combined with medications like chlorpheniramine. Heat stroke and hospitalization may occur in some people, especially in warm weather and during vigorous exercise. Children are more likely to experience this problem. Talk with your doctor before using these medications together. Drink plenty of fluids during warm weather and when exercising. Call the doctor if you have decreased sweating or a fever. You may also experience drowsiness, dizziness, or lightheadedness when taking these medications together. Avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.

Do not stop taking any medications without consulting your healthcare provider.
