doxylamine (cont.)


What happens if I miss a dose (Aldex AN, Nytol Maximum Strength, Unisom)?

If you miss a dose, take it as soon as you remember. It is best to take doxylamine only when you can devote several hours to sleep. If it is almost your normal waking hour, skip the missed dose and wait until you are ready for bed again. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Aldex AN, Nytol Maximum Strength, Unisom)?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include extreme drowsiness, loss of coordination, dry mouth, or seizure (convulsions).

What should I avoid while taking doxylamine (Aldex AN, Nytol Maximum Strength, Unisom)?

Do not use any other over-the-counter cold, allergy, or sleep medication without first asking your doctor or pharmacist. Antihistamines are contained in many medicines available over the counter. If you take certain products together you may accidentally take too much antihistamine. Read the label of any other medicine you are using to see if it contains an antihistamine such as doxylamine, chlorpheniramine or diphenhydramine.

This medication can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid becoming overheated or dehydrated during exercise and in hot weather.

Avoid drinking alcohol while you are taking this medication. Alcohol can add to drowsiness caused by an antihistamine.

What other drugs will affect doxylamine (Aldex AN, Nytol Maximum Strength, Unisom)?

Cold or allergy medicine, narcotic pain medicine, other sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by doxylamine. Tell your doctor if you need to use any of these other medicines while you are taking doxylamine.

Tell your doctor about all other medications you use, especially:

  • a diuretic (water pill);
  • diphenhydramine (Benadryl) applied to the skin as a spray, cream, lotion, gel, or stick;
  • bronchodilators such as ipratroprium (Atrovent) or tiotropium (Spiriva);
  • medication to treat irritable bowel syndrome;
  • bladder or urinary medications such as oxybutynin (Ditropan, Oxytrol) or tolterodine (Detrol);
  • aspirin or salicylates (such as Disalcid, Doan's Pills, Dolobid, Salflex, Tricosal, and others); or
  • other antihistamines, or medicine to treat motion sickness.

This list is not complete and there may be other drugs that can interact with doxylamine. Tell your doctor about all your prescription and over-the-counter medications, vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start a new medication without telling your doctor.

Where can I get more information?
