Dallergy

Pronunciation: KLOR-fen-IR-a-meen/FEN-il-EF-rin/METH-skoe-POL-a-meen
Generic Name: Chlorpheniramine/Phenylephrine/Methscopolamine
Brand Name: Dallergy

Dallergy is used for:

Relieving congestion, sneezing, runny nose, and itchy, watery eyes due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.

Dallergy is an antihistamine, decongestant, and anticholinergic combination. It works by blocking histamine, a substance in the body that causes sneezing, runny nose, and watery eyes. It also relieves nasal congestion by shrinking the nasal mucous membranes, which promotes nasal drainage, and dries the chest by decreasing lung secretions.

Do NOT use Dallergy if:

• you are allergic to any ingredient in Dallergy


• you are pregnant or breast-feeding


• you take sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days


• you are taking or have taken medicine for high blood pressure or depression in the last 14 days


• you have a history of narrow-angle glaucoma, blockage in the stomach or intestines, peptic ulcer disease, intestinal or bowel problems, difficulty urinating, inflammation of the esophagus from reflux disease, difficulty swallowing, or uncontrolled bleeding


• you have severe heart disease or severe high blood pressure

Contact your doctor or health care provider right away if any of these apply to you.
