Not Medical Advice: A round yellow pill (it does appear somewhat light orange in color) imprinted with 2632 on one side and imprinted with V (a V that looks similar to a square root sign) on the other side is cyclobenzaprine hydrochloride 10mg. It is a skeletal muscle relaxant and is used in treating migraine, muscle spasm, fibromyalgia, sciatica and temporomandibular joint disorder.

Cyclobenzaprine hydrochloride is marketed under the brand names Flexeril, Amrix, Fexmid, and Comfort Pac with Cyclobenzaprine.

People who have used a MAO inhibitor (isocarboxazid, tranylcypromine, phenelzine, selegiline) in the last 14 days should not take cyclobenzaprine. Those who have had a recent heart attack, or who have congestive heart failure, heart block, heart rhythm disorder, or an overactive thyroid should also not take cyclobenzaprine. Those on cyclobenzaprine should avoid drinking alcohol.

You should consult your doctor before taking cyclobenzaprine if you have glaucoma, problems with urination, liver disease, or an enlarged prostate.

Common side effects of cyclobenzaprine include blurred vision, constipation, diarrhea, dry throat or mouth, dizziness, drowsiness, fatigue, loss of appetite, muscle weakness, nausea, or stomach pain. Consult your physician if any of these common side effects become persistent.
