Cyclobenzaprine

Cyclobenzaprine is a skeletal muscle relaxant prescribed for muscle spasms. It acts in the brain and nervous system rather than directly on muscle tissue, which allows tight muscles to relax. Treatment is short term, usually while an acute strain settles.

Key points

  • Cyclobenzaprine belongs to the skeletal muscle relaxant class and is used to treat muscle spasms.
  • Its effect begins within about an hour and lasts between 12 and 24 hours.
  • It is supplied as a 15mg tablet.

What it is used for

Cyclobenzaprine is prescribed for Muscle Spasm, most often after an acute injury or strain. Easing spasm makes rest and physical therapy easier during recovery. It sits within Pain Management as a short-term measure, generally used alongside rest and physical therapy to address acute symptoms.

How it works

The medicine works centrally. It influences motor activity at the brainstem level, rather than acting at the motor endplate or directly on the muscle. By dampening the nerve signalling that governs muscle tone, it lowers the intensity of involuntary contractions.

Forms and brands

Cyclobenzaprine is available as a tablet in a 15mg strength: Cyclobenzaprine. Pharmacy partners in India ship orders to Malaysia in discreet packaging.

Safety

Cyclobenzaprine is not suitable after a recent myocardial infarction, in people with heart rhythm disorders, or in hyperthyroidism. It may impair your ability to drive or operate machinery, so wait until you know how it affects you before driving.

Drowsiness, dry mouth and dizziness are common; fatigue and confusion can also occur. Arrhythmia and serotonin syndrome are serious effects that need immediate medical attention.

Alcohol can make the medicine’s effects worse, and other central nervous system depressants add to its sedative action. In pregnancy it should be used only if clearly needed, and it is not recommended while breastfeeding. Tell your doctor if you are pregnant, planning a pregnancy or breastfeeding, and contact them immediately if you become pregnant while taking it.
