Took 20mg of Prozac (fluoxetine) for 8 mos. Been off for two weeks. Can I now take st. Johns wort. Didnt like side effects of prozac (fluoxetine)?

Probably. Prozac (fluoxetine) will stay in your system for 4-6 wks & st johns is a weak maoi which theoretically could b a problem but st. John's is so weak i've had pts who've taken it with their antidepressants including Prozac (fluoxetine) with no problems.
