What you should know before using

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatrics

Studies with the skeletal muscle relaxants have been done only in adult patients, and there is no specific information comparing use of these medicines in children with use in other age groups. However, carisoprodol and chlorzoxazone have been used in children. They have not been reported to cause different side effects or problems in children than they do in adults.

Geriatric

Many medicines have not been tested in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information about the use of skeletal muscle relaxants in the elderly.

Although skeletal muscle relaxants have not been shown to cause birth defects or other problems, studies on birth defects have not been done in pregnant women. Studies in animals with metaxalone have not shown that it causes birth defects.

Breast Feeding

Carisoprodol passes into the breast milk and may cause drowsiness or stomach upset in nursing babies. It is not known whether chlorphenesin, chlorzoxazone, metaxalone, or methocarbamol passes into the breast milk. However, these medicines have not been reported to cause problems in nursing babies.
