Zedex-Sf

Composition of Zedex-Sf

Zedex-Sf contains Dextromethorphan hydrobromide 10 mg + Guaifenesin 100 mg + Phenylephrine hydrochloride 5 mg per 5 ml. It belongs to the Antitussive (NMDA receptor antagonist/central cough suppressant) + Expectorant + Sympathomimetic decongestant class of medicines.

Uses of Zedex-Sf

Symptomatic relief of dry or productive cough associated with common cold/upper respiratory tract infections; helps relieve chest congestion and nasal stuffiness.

Key benefits

• Reduces cough frequency
• Helps loosen and expel mucus
• Relieves chest congestion
• Reduces nasal congestion/stuffiness

How Zedex-Sf works

Dextromethorphan suppresses the cough reflex by acting on the cough center in the brain. Guaifenesin loosens and thins mucus to make coughing out phlegm easier. Phenylephrine is a decongestant that constricts nasal blood vessels to reduce swelling and congestion.

How to take Zedex-Sf

Oral syrup. Shake well before use and measure with a cup/spoon. Usually taken 2–3 times daily as advised by a doctor; may be taken with or without food. Do not exceed the recommended dose and avoid using multiple cough/cold products together.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
