Introduction

Phenylephrine, acetaminophen, dextromethorphan, and chlorpheniramine tablets are commonly used for symptomatic treatment of the common cold, helping to relieve symptoms such as fever, nasal congestion, cough, sore throat, and body aches. The medication should be taken strictly according to the recommended dosage to avoid overdose or concurrent use with other similar cold medicines. If symptoms worsen or serious adverse reactions occur, medical attention should be sought promptly. Acetaminophen, one of the ingredients, works by inhibiting prostaglandin synthesis.

Phenylephrine-metaraminol-dextromethorphan tablets are a commonly used symptomatic treatment option for the common cold, effectively relieving symptoms such as fever, nasal congestion, cough, sore throat, and body aches. Medication should be taken strictly according to the recommended dosage to avoid overdose or concurrent use with similar cold medicines. If symptoms worsen or serious adverse reactions occur, medical attention should be sought promptly.

1. Relieves fever and pain: The active ingredient acetaminophen inhibits prostaglandin synthesis and reduces the sensitivity of the body's temperature regulation center, effectively alleviating discomfort caused by the common cold such as fever, headache, joint pain, and muscle aches.

2. Reduces nasal congestion and runny nose: Pseudoephedrine hydrochloride constricts blood vessels in the nasal mucosa, reducing nasal congestion and swelling, thereby improving symptoms of nasal obstruction and rhinorrhea and promoting easier breathing.

3. Suppresses cough: Dextromethorphan hydrobromide is a centrally acting antitussive that acts on the cough center in the brain to reduce the cough reflex, making it suitable for dry cough or cough with minimal phlegm due to the common cold.

4. Alleviates throat discomfort: The medication helps soothe inflammation of the throat mucosa, reducing symptoms such as soreness, swelling, dryness, and itching, and easing pain during swallowing.

5. Be aware of contraindications: The drug is contraindicated in patients with severe liver or kidney dysfunction. Pregnant women, nursing mothers, children, and elderly individuals should use only under medical supervision. Avoid taking other medications containing the same ingredients simultaneously.

During a cold, ensure adequate sleep and avoid fatigue. Drink plenty of warm water to stay hydrated, maintain a light and easily digestible diet, and avoid spicy or greasy foods. Keep indoor areas well-ventilated and minimize outdoor activities and contact with others to support recovery.
