... was prescribed 5th of Flexeril to take for 3 weeks and 2 days after he stopped taking them he started to experience confusion, unusual paranoid thoughts, dizziness, depressing etc. He was not taking any other prescription drugs or any drugs while on this medication. Doctors are saying that Flexeril does not cause withdrawal symptoms but side effects and withdrawals go hand in hand. I personally think it altered his brain chemistry and just threw everything out of whack. It has been 20 days and he still feels this way, any advice would be much appreciated. Also, they did a ct scan and blood tests 0- everything seemed normal
