Cetirizine / Pseudoephedrine Side Effects
What should I watch for?
Visit your doctor or health care professional for regular check ups. Tell your doctor or health care professional if your symptoms do not improve. If you have high blood pressure, check your blood pressure regularly. Ask your health care professional what your blood pressure should be, and when you should contact him or her.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
