Pseudox M syrup 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.
Pseudox M syrup 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.
