Cyclobenzaprine?

Cyclobenzaprine is a prescription muscle relaxant used for short-term relief of muscle spasms and pain from acute musculoskeletal conditions (not for chronic spasticity from neurological diseases).

Key points
- Brand names: Flexeril, Amrix, Fexmid.
- How it works: Centrally acting; probably works on brainstem pathways to reduce muscle activity. It also has anticholinergic and sedating effects.
- Typical use: Short-term (usually 2–3 weeks) for acute muscle strain or sprain.
- Dosing (general guide): Often 5 mg taken 3 times daily (15 mg/day). Some people may be started on 5 mg and increased to 10 mg 3 times daily if needed, but do not exceed 30 mg/day. Always follow your clinician’s instructions.
- Common side effects: Drowsiness, dizziness, dry mouth, fatigue, blurred vision, constipation. Elderly people may have more confusion or falls.
- Important cautions:
- Avoid in a recent MAOI antidepressant use (within about 14 days) and discuss any antidepressant or other CNS-active meds with your doctor.
- Can interact with other CNS depressants (alcohol, sedatives) and with drugs that affect heart rhythm.
- Has anticholinergic effects; use caution if you have glaucoma, urinary retention, or significant urinary symptoms.
- Use with caution in the elderly; start low and monitor.
- Not typically used long-term; stop if no improvement in a couple of weeks.
- Contraindications: Hypersensitivity to cyclobenzaprine; recent MI or arrhythmias; significant conduction abnormalities; concurrent or recent use of MAO inhibitors.
- Pregnancy/lactation: Discuss with your clinician; options may differ based on risk/benefit.
- Overdose: Can cause severe drowsiness, dizziness, confusion, and heart rhythm changes. Seek urgent medical care if overdose is suspected.
