Dexchlorpheniramine Maleate, Pseudoephedrine Sulphate, Guaifenesin

Dexchlorpheniramine Maleate, Pseudoephedrine Sulphate, Guaifenesin

This medication is a combination of three active ingredients: dexchlorpheniramine maleate, pseudoephedrine sulfate, and guaifenesin. Dexchlorpheniramine maleate is an antihistamine that helps relieve symptoms of allergies such as sneezing, itching, watery eyes, and runny nose. Pseudoephedrine sulfate is a decongestant that shrinks blood vessels in the nasal passages, reducing congestion. Guaifenesin is an expectorant that helps loosen mucus and phlegm in the lungs, making it easier to cough up.


This medication is indicated for the relief of symptoms associated with allergic rhinitis, sinus congestion, and chest congestion caused by the common cold or respiratory allergies.


The dosage may vary depending on age and severity of symptoms. It is important to follow the dosage instructions provided by your healthcare provider or as directed on the medication label.


This medication is contraindicated in individuals with hypersensitivity to any of its components, as well as in patients with severe hypertension, severe coronary artery disease, narrow-angle glaucoma, or during an acute asthma attack.

Special Precautions

Use caution in patients with cardiovascular disease, hypertension, hyperthyroidism, diabetes, prostatic hypertrophy, and hepatic or renal impairment. Avoid use in pregnant women, particularly during the first trimester, unless the potential benefits outweigh the risks.

Side Effects

Common side effects may include dizziness, drowsiness, headache, nervousness, nausea, insomnia, and dry mouth. Serious side effects such as severe allergic reactions, chest pain, irregular heartbeat, and difficulty urinating should be reported to a healthcare professional immediately.

Drug Interactions

Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as certain drugs may interact with dexchlorpheniramine, pseudoephedrine, or guaifenesin, potentially affecting their efficacy or increasing the risk of adverse effects.
