Tell your doctor of all prescription and nonprescription medication you may use, especially: other asthma medications (e.g., albuterol, prednisone/steroids, theophylline), oral diabetes medication (e.g., glipizide, glyburide). Tell your doctor if you take any drugs that cause drowsiness such as: medicine for sleep (e.g., sedatives, tranquilizers), anti-anxiety drugs (e.g., diazepam, lorazepam), narcotic pain relievers (e.g., codeine, morphine), psychiatric medicines (e.g., phenothiazines such as chlorpromazine or tricyclic antidepressants such as amitriptyline), anti-seizure drugs (e.g., carbamazepine, topiramate), muscle relaxants, certain antihistamines (e.g., diphenhydramine). Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-causing ingredients. Ask your pharmacist about the safe use of these products. Do not start or stop any medicine without doctor or pharmacist approval.
