Before Using Antispasmodic

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Pediatric

Severe side effects may be more likely to occur in infants and children, especially those with spastic paralysis or brain damage. Unusual excitement, nervousness, restlessness, or irritability and unusual warmth, dryness, and flushing of skin are more likely to occur in children, who are usually more sensitive to the effects of belladonna alkaloids. Also, when belladonna alkaloids are given to children during hot weather, a rapid increase in body temperature may occur. In addition, the barbiturate in this medicine could cause some children to become hyperactive.

Geriatric

Confusion or memory loss; constipation; difficult urination; drowsiness; dryness of mouth, nose, throat, or skin; and unusual excitement, nervousness, restlessness, or irritability may be more likely to occur in the elderly, who are usually more sensitive than younger adults to the effects of belladonna alkaloids and barbiturates. Also, eye pain may occur, which may be a sign of glaucoma.
