Clarityne General Information
Clarityne is an antihistamine that treats symptoms such as itching, runny nose, watery eyes, and sneezing from "hay fever" and other allergies. It is also used to relieve itching from hives.
Clarityne does not prevent hives or prevent/treat a serious allergic reaction (e.g., anaphylaxis). Therefore, if your doctor has prescribed epinephrine to treat allergic reactions, always carry your epinephrine injector with you. Do not use Clarityne in place of your epinephrine.
If you are self-treating with Clarityne, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist.
Do not use Clarityne in children younger than 6 years unless directed by the doctor. If you are using the chewable tablets, do not use in children younger than 2 years unless directed by your doctor.
How to Use Clarityne
If you are using the over-the-counter product to self-treat, read all the directions on the product package before taking Clarityne. If your doctor has prescribed Clarityne, follow your doctor's directions and the instructions on your prescription label. If you have any questions, consult your doctor or pharmacist.
Take Clarityne by mouth with or without food, usually once a day or as directed by your doctor or the product package. If you are using the chewable tablets, chew each tablet well and swallow. Dosage is based on your age, condition, and response to treatment. Do not increase your dose or take Clarityne more often than directed. Do not take more of Clarityne than recommended for your age.
Tell your doctor if your allergy symptoms do not improve after 3 days of treatment or if your hives last more than 6 weeks. Seek immediate medical attention if your condition worsens or you think you have a serious medical problem (e.g., very serious allergic reaction/anaphylaxis).
Clarityne Possible Side Effects
Clarityne usually has no side effects. If you have any unusual effects, contact your doctor or pharmacist promptly.
A very serious allergic reaction to Clarityne is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Clarityne Precautions
Before taking Clarityne, tell your doctor or pharmacist if you are allergic to it; or to desClarityne; or if you have any other allergies. Clarityne may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using Clarityne, tell your doctor or pharmacist your medical history. Do not self-treat with Clarityne without consulting your doctor first if you have certain medical conditions such as: kidney disease, liver disease.
Clarityne does not usually cause drowsiness when used at recommended doses. However, do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely.
If you have hives and your doctor has prescribed Clarityne, or if you are considering using Clarityne to treat your own hives, tell your doctor immediately if you have any of these other symptoms because they may be signs of a more serious condition: hives that are an unusual color, hives that look bruised or blistered, hives that do not itch.
The chewable tablets may contain aspartame. If you have phenylketonuria (PKU) or any other condition that requires you to restrict your intake of aspartame (or phenylalanine), consult your doctor or pharmacist about using Clarityne safely.
Older adults may be more sensitive to the side effects of Clarityne, especially drowsiness, or confusion. These side effects can increase the risk of falling.
During pregnancy, Clarityne should be used only when clearly needed and as directed by your doctor. Discuss the risks and benefits with your doctor before taking Clarityne.
Clarityne passes into breast milk. However, it is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.
Clarityne Possible Intercations
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.
