Doxylamine is used in the short-term treatment of insomnia (difficulty falling asleep or staying asleep). Doxylamine is also
used in combination with decongestants and other medications to relieve sneezing, runny nose, and nasal congestion caused
by the common cold. Doxylamine should not be used to treat children younger than 12 years of age. Doxylamine is in a class
of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic
symptoms.
Doxylamine comes as a tablet to take by mouth for sleep, and in combination with other medications as a liquid to treat symptoms
of the common cold. When doxylamine is used to reduce difficulty falling asleep, it usually is taken 30 minutes before bedtime.
When doxylamine is used to treat cold symptoms, it is usually taken every 4-6 hours. Follow the directions on the package
label or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Take doxylamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or
directed on the package label.
Doxylamine comes in combination with other cough and cold medications. Ask your doctor or pharmacist for advice on which product
is best for your symptoms. Check nonprescription cough and cold product labels carefully before using two or more products
at the same time. These products may contain the same active ingredient(s) and taking them together could cause you to receive
an overdose.
If you are taking doxylamine to treat insomnia, you will probably become very sleepy soon after you take the medication and
will remain sleepy for some time after you take the medication. Plan to remain asleep for 7-8 hours after taking the medication.
If you get up too soon after taking doxylamine, you may be drowsy.
Doxylamine should only be used to treat insomnia for a short time. Call your doctor if you feel that you need to take doxylamine
for longer than 2 weeks.
Cough and cold symptoms that get worse or that do not go away may be signs of a more serious condition. If you are taking
doxylamine in combination with other medications to treat cough and cold symptoms, call your doctor if your symptoms worsen
or if they last longer than 7 days.
If you are using the liquid, do not use a household spoon to measure your dose. Use the measuring cup or spoon that came with
the medication or use a spoon that is made especially for measuring medication.
