ANTIHISTAMINES - ORAL
Antihistamines are used to treat rash, hives, watery eyes, runny nose, itching, and sneezing due to allergies or the common cold. They may also be used to treat motion sickness, anxiety, or as a sleep aid (for insomnia).
How To Use
May be taken with food or milk if stomach upset occurs. Sustained-release or long acting tablets and capsules must be swallowed whole. Chewing or crushing them will destroy the long action and may increase side effects. For chewable tablets, chew thoroughly and swallow. Shake suspensions well before taking.

If they persist or become bothersome, inform your doctor. Notify your doctor if you develop: breathing difficulties, pounding or irregular heartbeat, ringing in the ears, difficulty urinating. If you notice other effects not listed above, contact your doctor or pharmacist.
Tell your doctor your medical history, especially of: glaucoma (narrow angle), stomach ulcers, difficulty urinating (e.g., enlarged prostate), heart disease, high blood pressure, seizures, lung problems, overactive thyroid.
