    Cetirizine

    Cetirizine does interact with other substances.

    For example, avoid consuming alcoholic drinks while you take cetirizine. Doing so may be dangerous.

    Mixing cetirizine with alcohol can cause drowsiness or make you less alert.

    If you take any type of tranquilizer, sedative, or sleep aid, make sure to mention this to your doctor before you use cetirizine.

    Mixing cetirizine with drugs that depress your central nervous system can increase sleepiness.

    It can also further affect your mental and nervous system functions.

    There is a possibility of a drug interaction between cetirizine and theophylline. Theophylline (Theo-24) is a drug that some people with asthma and other lung problems take.

    In some instances when the two drugs were taken, it took longer for cetirizine to leave the body.

    However, the interaction may be dose-related. It has only been reported with daily theophylline doses of 400 mg or more.

    Talk to your doctor if you take theophylline and are considering cetirizine.

    Cetirizine-D and brand-name versions, such as Zyrtec-D, are combination
