This safety alert does not apply to this medication, but only to some products which contain this medication. In addition, it is important that you know that there is not a problem with most of the products described in this medication monograph. And some drug companies may decide to seek full approval from the FDA so that they can continue marketing their products.
On March 2, 2011, the Food and Drug Administration (FDA) issued a safety alert about certain unapproved prescription cough, cold, and allergy products containing this drug in combination with other drugs. These products are not currently approved by the FDA for safety, effectiveness, and quality. FDA asked drug companies to stop shipping most of these products for sale in the US within the next 6 months. Although some of these products have been marketed for many years, laws about what a company must prove to FDA for drug product approval have gotten tougher and increased enforcement of these laws is now taking place. The FDA took this action due to concerns about certain potential risks associated with use of these medications. These risks may include:
- the possibility of improper use in infants and young children
- potentially risky combinations of ingredients
- patients receiving too much or too little of the medication because of problems with the way some ''timed-release'' products are made
If you are concerned that the prescription cough, cold, and allergy medication you are taking is not approved by the FDA, you should talk to your doctor or pharmacist. If the medication you are taking is not approved, your doctor can prescribe another prescription medication or your doctor or pharmacist can suggest an over-the-counter (OTC) cough, cold, and allergy product for your condition. There are many safe and effective alternative approved products that can be taken instead. Your doctor probably prescribed the medicine without knowing that FDA had not approved it. This is because it has been so difficult for doctors and pharmacists to find out that these products are unapproved. For additional information:
- You can visit the FDA website (http://www.fda.gov/ForConsumers/ConsumerUpdates/ucm244852.htm ) for more information about this action to remove unapproved cough, cold, and allergy products from the market.
- You can find a list of unapproved products by going to (http://goo.gl/Gqc7d ).

WHY is this medicine prescribed?
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 cause sleepiness in children. 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.
HOW should this medicine be used?
Doxylamine comes as a tablet to take by mouth for sleep, and in combination with other medications as a liquid and liquid-filled capsule 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 to 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 alone and in combination with pain relievers, fever reducers, and cough suppressants, If you are choosing a product to treat cough or cold symptoms, 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.
Nonprescription cough and cold combination products, including products that contain doxylamine, can cause serious side effects or death in young children. Do not give nonprescription products that contain doxylamine to children younger than 4 years of age. Ask a doctor before giving these products to children 4 to 12 years of age.
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 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 to 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.
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.
