If i had one seizure in the past 16 ears and take dilantin can i take septra (sulfamethoxazole and trimethoprim) for infection or will it cause seizure?

Not seizure...: But the drug can increase the half life of Dilantin so potentially toxic levels of Dilantin could occur.

Avoid unnecessary : As a rule we are all too dependent on medication. Whenever we feel a little ill, we expect a medication to make us better. We also feel that if we are given a medication to take, we must continue taking it or will be sick again. Both these issues are not always valid. Do you need these medications? Can you lead a healthy life and avoid the need for medication? Try to avoid risks.
