What medications interact with anticonvulsants?

Donna Hill Howes, RN
Family Practitioner

If you are taking an anticholinergic drug, metformin, primidone, rufinamide, a selective serotonin reuptake inhibitor, or valproate, topiramate may not be a good option for you.

If you are using azelastine nasal spray, a carbonic anhydrase inhibitor, a central nervous system depressant, a hormonal contraceptive, orphenadrine, paraldehyde, thalidomide, or ulipristal, topiramate can lead to side effects and should be avoided.

If you are taking lamotrigine, valproic acid may not be a good option for you.

If you are taking a salicylate, valproic acid and topiramate may not be good options for you.

If you take topiramate, you should avoid kava kava.
