in breast milk. However, cyclobenzaprine is related
to tricyclic antidepressants, and some of those
drugs do appear in breast milk. If this med is
essential to your health, your doctor may advise
you to discontinue breastfeeding your baby until
your treatment is finished.
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 and Xanax Tramadol (Ultram)
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.
