Muscle spasm treatment can range from massage and stretching on the holistic side to drugs on the conventional medical side. To help loosen up muscle spasm, some people take Flexeril (also known as Cyclobenzeprine). This drug is one type of skeletal muscle relaxer. Here is a rundown on Flexeril, including side effects, generic information, dosage and storage information, and more.

Brand Name :
Flexeril. By prescription only.
Cyclobenzeprine. Cyclobenzeprine is available in generic form, by prescription only.
Class and Drug Action:
Skeletal Muscle Relaxant. Cyclobenzeprine works in the central nervous system to relieve skeletal muscle spasm throughout the body. It is not effective, however, for conditions involving the nervous system, such as multiple sclerosis. Cyclobenzeprine is used short-term, in conjunction with physical therapy and rest for acute cases of muscle injury, for example sprains and strains.
Duration of use should be no longer than 2-3 weeks. Cyclobenzeprine is taken by mouth up to 3 times per day, unless otherwise prescribed by your doctor. DO NOT INCREASE YOUR DOSAGE! If you miss a dose, and it is now closer the time of the next dose, just resume taking the medication with the next scheduled time. Do not double dose to make up for a missed dosage.
Store cyclobenzaprine at room temperature or as directed by your pharmacist.
The most common side effects include:
- dry mouth
- blurred vision
- unplesant taste
- abdominal pain or discomfort
More Serious Side Effects:
Serious side effects are rare, but if these do occur they require prompt medical attention 2:
- mental and mood changes, for example hallucinations and confusion
- difficulty in urinating
- dark urine
- fast, pounding and/or irregular heartbeat
- yellowing of the eyes and/or skin
- stomach and/or abdominal pain
- persistent nausea, vomiting and/or lack of appetite

The elderly will be more sensitive to the side effects associated with this disease. Pregnant women should use only when absolutely necessary; the drug might pass on to the breast milk.
Because side effects include dizziness and drowsiness, exercise caution when deciding to drive a car or operate machinery. Alcohol will amplify these side effects, and is best limited, to prevent injury or accident.
More Precautions - Drug Interactions:
Communicating with your Doctor is key. Always tell your doctor about the following:
- allergies, especially to Flexeril
- overactive thyroid
- any other heart problems including congestive heart failure, heart block or conduction disorders

Certain types of other medications (asthma, weight loss, stimulants, drugs that cause drowsiness and tricyclic antidepressants, to name a few) may cause drug interaction problems. Tell your doctor EVERYTHING you are taking. For more information use the Drug Finder.
