Feverfew Interactions with Antidepressant and Antispasmodic Drugs?

I am taking Welbutrin XL, magnesium, Zanaflex and birth control. I was wondering if any of these drugs would interact with feverfew. I have stress and tension headaches that go into migraines. I take Maxalt when they occur.

Although interactions with feverfew are unlikely, there are potential interactions that you should be aware of. The tranquilizing effect of feverfew may cause increased sedation with the antidepressant drug Wellbutrin. The antispasmodic action of feverfew could increase the effect of the antispasmodic drug Zanaflex.
