Brief Answer:
Possible adverse effect of topiramate use/increase.

Detailed Answer:
Hello and welcome to "Ask a Doctor " service.

I have read your query.

The answer to your question is yes, topiramate use, or increase, may be accompanied by abnormal vision features as a possible adverse effect that may happen in 2 to 13 % of users.

In such cases, the lowest possible dosage ( good control of the condition with minimal adverse effects ) is recommended.

Discuss with your Doctor for these issues.

Hope you found the answer helpful.

Let me know if I can assist you further.

Brief Answer:
These effects should subside with lower doses.

Detailed Answer:
Welcome back.

Topiramate may interfere with the nerve functions including those responsible for the vision.

These effects should improve in lower doses, or stopping the medication.

Hope I helped you.
