Before taking desloratadine:

- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: azithromycin (Zithromax, Zmax), cimetidine (Tagamet), erythromycin (E.E.S., Eryc, Eryped, others), fluoxetine (Prozac, Rapiflux, Sarafem, others), and ketoconazole (Nizoral). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had kidney or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking desloratadine, call your doctor.

Desloratadine comes as a tablet, oral solution (liquid), and an orally disintegrating tablet to take by mouth. It is usually taken once a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take desloratadine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
It is important to use a measuring device (dropper or an oral syringe) to accurately measure the correct amount of solution for each dose; do not use a household spoon.
To take the orally disintegrating tablet, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it on your tongue. The tablet will quickly dissolve and can be swallowed with saliva. Orally disintegrating tablets may be taken with or without water.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
Keep all appointments with your doctor.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription of desloratadine.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
