Your medicines

Take these together with care

We found interactions that usually need care rather than stopping a medicine. Your doctor may adjust a dose or check on you more often.

Topirva Topiramate Phenytoin Sodium

Moderate

Phenytoin Sodium and Topiramate are listed together as medicines that can interact. The leaflet names topiramate among the medicines whose action may be affected when phenytoin is taken with them. This can change how well topiramate works, so the usual dose may not suit you once both are in use. If you take both, tell your doctor or pharmacist, and don't change or stop either one on your own.

What should I do?

These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.

Topirva Topiramate Phenytoin Sodium

Minor

Taking Topiramate along with Phenytoin usually doesn't change how much Phenytoin is in your blood in any way that matters. In some people, though, adding Topiramate can push the Phenytoin level up. If you take both, your doctor may want to check your Phenytoin level, especially soon after Topiramate is started.

What should I do?

Little or no effect is expected. You usually do not need to change anything, but still tell your doctor or pharmacist about every medicine you take.

What do Major, Moderate and Minor mean?

Major

The combination can cause serious harm or stop a medicine from working. Usually avoided, or only used with close medical supervision.

Moderate

The combination may need care: a different dose, taking them at different times, or extra check-ups.

Minor

Little or no effect is expected. Usually nothing needs to change.

Duplicate

Two of your medicines contain the same ingredient, which can add up to a double dose.
