I am overweight and started taking adipex . Is it safe to take them together? I havent done it yet, so I have gone about a week without a BP pill . My head has started hurting , and I don't know if it is from the side effects of Adipex or from not taking BP pill. Maybe there is an over the counter pill I can take to see if it is a headache from side effect. if not I need to know can I take the two together- Example I take the Adipex around 7 or 8 am , and then take the Lisinopril around 11.
