What should you know about muscle relaxant for back spasm?

Back spasm can accompany muscle strain, non-specific low back pain, or irritation around the spine. A herniated disc or facet joint syndrome may need a different plan. The medicine can reduce protective tightening while the area settles, but it is not a substitute for examining strength, sensation, and movement.

Sleepiness, slowed reactions, dry mouth, and light-headedness are possible. Avoid alcohol and other sedating medicines unless a clinician has specifically checked the combination.

Use only the prescribed dose and duration. Keep gently mobile rather than staying in bed for long periods, and change position often. Heat may soothe tight muscles. Physiotherapy can address movement and control; options such as [Myofascial Release](/treatments/manual-and-manipulative-therapy/myofascial-release/) or [Dry Needling](/treatments/physiotherapy-and-rehabilitation/dry-needling/) should be selected after assessment. Read about [Back Muscle Spasm](/symptoms/back-muscle-spasm/).

Get urgent help for new leg weakness, numbness around the groin, inability to pass urine, loss of bowel control, fever with severe back pain, or pain after major trauma. Arrange review when symptoms are worsening, repeatedly returning, or not allowing normal walking or sleep.

Ask what cause is suspected, how long the medicine is appropriate, whether you may drive, and which exercises are suitable. Ask what symptoms would suggest a disc or nerve problem rather than a simple spasm.
