Question/Comment:
If someone has taken Flexeril & is having hallucinations 10 days after they stopped taking it, how long will it take before the drug gets out of their system? Her Dr is not taking her seriously & they are severe! Please advise.

iGuard Answer/Reply:
Flexeril will remain in the body on average about 4 days after a person stops taking the medication. If her doctor is not taking her seriously about the hallucinations, she could ask for a referral to another doctor for a second opinion to find the cause.

Question/Comment:
I have numerous muscle and joint issues which have always created issues with sleeping. We've tried different medicines but they always made me feel drugged when I would get up. Especially if I didn't get at least 6 hours of sleep. I have discovered that this medicine allows me to relax enough to go to sleep without the feeling of 'no control' I used to get with things like Soma and Baclofen. They would hit me like a ton of bricks. I'm thankful we discovered this combination

Question/Comment:
I take Flexeril w/Voltaren to relieve spasms & control pain (osteoarthritis) in my neck so bad I couldn't turn my head enough to drive. I take 75mg of Voltaren w/ Pepcid right after dinner & follow later w/10mg of Flexeril. I felt some benefits quickly - after about a week of that combo plus PT my issues were markedly reduced. Now almost all difficulty with my neck is gone. Voltaren can be dangerous to the liver so I know I won't have it much longer. I'm grateful for the combo!

Question/Comment:
I was told to take this for my newly diagnosed connective tissue issues. I take 1mg of xanax at dinner to help with aniety and for sleep. I've been taking the 1mg for 3 weeks straight. Before that it was just occationally. Since my connective tissue issues have been worse the doctor told me to stop the xanax and use the muscle relaxer and the celebrex. I took the muscle relaxer last night but not the celebrex. Just wanted to try one thing at a time but now today I feel like I am having withdraw symptoms from the xanax. The pharmcy told me that I could just stop. I felt since I was only taking it about twice a week and then for 3 weeks straight I would be fine. I don't think that is the case with me. My question to anyone that has gone through this is can I ween myself from the xanax while taking the muscle relaxer? I am probable going to use the muscle relaxer at bedtime around 10 and I take the xanax at about 7 in the evening. DIdn't know if I would do harm to myself. I know I can come off the xanax but it might take about two weeks to ween myself. I took it for two months last year and stopped had withdraw symptoms and then wound up weening myself and did it fine. Then the other health stuff came up and I had to take one or two a week to get me through and help me sleep. Any suggestions would be helpful. Thanks

iGuard Answer/Reply:
You can taper off the Xanax while taking cyclobenzaprine. The issue with taking both of these drugs is that there is an increased risk of drowsiness and sedation since both of these medications have these side effects. Since you are decreasing the dose of the Xanax, you will be less likely to experience drowsiness. Also taking them in the evening will allow you to better manage any drowsiness that may occur since you will be close to bedtime.

I know I'm not an expert but I will tell you that you definitely will have withdrawal symptoms from xanax. It depends how many mg's and how much you took but you'll feel something. As the iGuard response said it is best to taper off u said u took 1 @ nite so instead take 1/2 for like a week than maybe do every other day and then u should be ok. I take valium but i take like 3 a day for anxiety and I know when I don't take any for a couple days I feel it, which is kinda sucky knowing ur dependent.
