What should I avoid while taking doxylamine (Aldex AN, Unisom)?
Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Antihistamines are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine.
This medication may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Doxylamine can decrease sweating and you may be more prone to heat stroke.
Drinking alcohol can increase certain side effects of doxylamine.
