WARNINGS SECTION.

WARNINGS. In the presence of high environmental temperature, heat prostration can occur with belladonna alkaloids (fever and heatstroke due to decreased sweating).Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance, treatment with this drug would be inappropriate and possibly harmful.Donnatal(R) Elixir may produce drowsiness or blurred vision. The patient should be warned, should these occur, not to engage in activities requiring mental alertness, such as operating motor vehicle or other machinery, and not to perform hazardous work.Phenobarbital may decrease the effect of anticoagulants, and necessitate larger doses of the anticoagulant for optimal effect. When the phenobarbital is discontinued, the dose of the anticoagulant may have to be decreased.Phenobarbital may be habit forming and should not be administered to individuals known to be addiction prone or to those with history of physical and/or psychological dependence upon drugs.Since barbiturates are metabolized in the liver, they should be used with caution and initial doses should be small in patients with hepatic dysfunction.
