Doxylamine (Dormidina) additional information
Common uses
Doxylamine, an antihistamine, is used in the short-term treatment of insomnia. Doxylamine also is used, in combination with decongestants, to relieve cough and cold symptoms.
Directions
Doxylamine comes as a tablet to take by mouth. Doxylamine has a quick acting sedative and sleep-inducing effect. The dose of doxylamine recommended for adults is 1 tablet (25 mg.) given 30 minutes before going to bed. For young people less than 18 years of age consult your doctor.
For cold symptoms, doxylamine usually is taken every 4-6 hours. Take doxylamine exactly as directed. Do not take more or less doxylamine or take it more often than prescribed by your doctor. Do not give doxylamine to a child younger than 12 years of age unless directed to do so by a doctor.
Doxylamine may cause an upset stomach. Take doxylamine with food or milk.
If you miss a dose, take it as soon as remembered if it is within an hour or so. If you do not remember until later, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.
