I'm not familiar with Fematril but to be certain I would advise you speak to your Doctor about this.
Yes, St John's Wort can decrease the effectiveness of birth control up to 50 percent
Antibiotics will completely eliminate the usefulness of a birth control pill. A secondary source, such as condoms, should be used while on antibiotics to continue the prevention of pregnancy. Usually the medical information on the birth control package states which medicines will interfere with the product.
Some herbs can decrease the effectiveness of the birth control pill. Contact your health care provider or pharmacist for advice specific to your situation.
I have heard that St. John's Wart can decrease the effectiveness of birth control as well as certain antibiotics, seizure medications, etc. on Planned Parenthood and other medical websites. If you really want to make sure you can take it without lowering the effectiveness of your birth control, I would suggest talking to your doctor. :)
X-rays do not lower the effectiveness of the birth control pill.
Yes. Even missing one day of the pill will reduce the effectiveness of the pill. If you missed a week, the effectiveness of the pill increases a lot.

Probably not a good idea. St. Johns Wort can decrease the effectiveness of the pill, if you need that medication, take it, but use a back- up method meanwhile
