How It Works
The muscle-relaxing effects of these medicines are most likely the result of their ability to depress the central nervous system.

Muscle relaxants are not recommended for use by pregnant women, older adults, or people who have depression or a history of drug or alcohol addiction.
How Well It Works
Possible side effects of muscle relaxants include:
- Drowsiness or dizziness.
- Possible addiction or dependence.

- Urinary retention.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Muscle relaxant medicines work best when they are taken before bedtime. They should not be used by a person who needs to drive or operate machinery.
Use of muscle relaxants is restricted to short-term use to avoid addiction.
