The antihistamine in this medicine will add to the effects of alcohol and other CNS depressants including tricyclic antidepressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are other antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Examples of Tricyclic antidepressants are amitriptyline [e.g. Elavil], amoxapine [e.g. Asendin], clomipramine [e.g. Anafranil], desipramine [e.g. Pertofrane], doxepine [e.g. Sinequan], imipramine [e.g. Tofranil], nortriptyline [e.g. Aventyl], protriptyline [Vivactil], trimipramine [e.g. Surmontil]. Check with your doctor before taking any of the above while you are taking this medicine.
The antihistamine in this medicine may cause some people to become drowsy, dizzy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.
Antihistamines may cause dryness of the mouth, nose, and throat. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
The decongestant in this medicine may cause some people to be nervous or restless or to have trouble in sleeping. If you have trouble in sleeping, take the last dose of this medicine for each day a few hours before bedtime. If you have any questions about this, check with your doctor.
