Flexeril Directions

Flexeril may be taken with or without food. Flexeril should be used only for short periods (no more than 3 weeks). Since the type of injury that Flexeril treats should improve in a few weeks, there is no reason to use it for a longer period. Flexeril may cause dry mouth. Sucking a hard candy, chewing gum, or melting ice chips in your mouth can provide temporary relief.

Flexeril Precautions

The effects of Flexeril during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. It is not known if Flexeril appears in breast milk. However, cyclobenzaprine is related to tricyclic antidepressants, and some of those drugs do appear in breast milk. If this medication is essential to your health, your doctor may advise you to discontinue breastfeeding your baby until your treatment is finished.

Flexeril Drug Interactions

Serious, potentially fatal reactions may occur if you take Flexeril with an antidepressant drug known as an MAO inhibitor (such as Nardil, Parnate) or if it has been less than 2 weeks since you last took an MAO inhibitor. You should closely follow your doctor's advice regarding discontinuation of MAO inhibitors before taking Flexeril. Avoid alcoholic beverages while taking Flexeril. If Flexeril is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Flexeril with the following: Barbiturates such as phenobarbital, Guanethidine and other high blood pressure drugs, other drugs that slow the central nervous system, such as Halcion, Xanax and Tramadol (Ultram).

Missed Dose of Flexeril

If you miss a dose of Flexeril, Take it as soon as you remember, if it is within an hour or so of your scheduled time. If you do not remember until later, skip the missed dose and go back to your regular schedule. Do not take 2 doses of Flexeril at once.

Flexeril Dosage

ADULTS: The usual dose is 10 milligrams 3 times a day. You should not take more than 60 milligrams a day.

Flexeril Notes

Flexeril is not a substitute for the physical therapy, rest, or exercise that your doctor orders for proper healing. Although Flexeril relieves the pain of strains and sprains, it is not useful for other types of pain.
