Effexor is a very strong drug, when I was taking it I couldn’t take anything else without having a reaction, even advice.
There are sites online where you can look for drug interactions. One I remember with Effexor was loperamide - which is diaherria medicine. I had to just suffer with no relief while on Effexor if I got sick. : \
My best advice to you is to ask your doctor. Only he can provide you with the proper 411. If your not under a doctors care and these are meds you have bought on the street??
stop right there and flush them, this may sound stupid but its true!!!
good luck
soma is a muscle relaxer. Check w/your pharmacist for a quick answer. I don’t know what Effexor is prescribed for.
