What should I know about cetirizine and pseudoephedrine?

Do not take cetirizine and pseudoephedrine if within the previous two weeks you have taken a monoamine oxidase inhibitor (MAOI), such as isocarboxazid, phenelzine, rasagiline, selegiline, or tranylcypromine. Cetirizine and pseudoephedrine can make you drowsy or dizzy and may affect your ability to drive or engage in activities that require you to be alert. Do not drive or engage in these types of activities until you know how you will react to the medication. Do not drink alcohol with cetirizine and pseudoephedrine. Alcohol can make the drowsiness and dizziness worse. Medications that cause drowsiness, such as sleep medications, narcotics for pain relief, tranquilizers, and muscle relaxants, should also be used with caution while taking cetirizine and pseudoephedrine. People with certain medical conditions should use cetirizine and pseudoephedrine with caution. These include: glaucoma, difficulty urinating, high blood pressure, heart, kidney or liver disease, diabetes, and thyroid disorders. Pregnant and breast-feeding women should discuss with their doctor the risks and benefits of using cetirizine and pseudoephedrine. The elderly may be more sensitive to the effects of cetirizine and pseudoephedrine and may be more susceptible to side effects.
