In November 2000, the Food and Drug Administration (FDA) issued a public health warning regarding phenylpropanolamine (PPA) due to the risk of hemorrhagic stroke. The FDA, supported by results of a research program, requested that manufacturers voluntarily discontinue marketing products that contain PPA and that consumers work with their healthcare providers to select alternative products.
Antihistamine, decongestant, and anticholinergic combinations are used to treat the nasal congestion (stuffy nose) and runny nose caused by allergies and/or the common cold.
Antihistamines work by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. The antihistamine contained in these combinations is chlorpheniramine.
The decongestants in these combinations, phenylephrine, and pseudoephedrine produce a narrowing of blood vessels. This leads to clearing of nasal congestion, but it may also cause an increase in blood pressure in patients who have high blood pressure.
Anticholinergics, such as atropine, hyoscyamine, methscopolamine, and scopolamine may help produce a drying effect in the nose and chest.
Some of these medicines are available without a prescription.
Do not give any over-the-counter (OTC) cough and cold medicine to a baby or child under 4 years of age. Using these medicines in very young children might cause serious or possibly life-threatening side effects .
