SINEX TABLETS

Mechanism of Action:

• Chlorpheniramine Maleate: An antihistamine that blocks H1-receptor sites, reducing allergy symptoms like sneezing and runny nose.
• Acetaminophen (Paracetamol): An analgesic that increases the pain threshold and reduces fever by acting on the hypothalamic heat-regulating center.
• Pseudoephedrine: A decongestant that stimulates alpha-adrenergic receptors, leading to vasoconstriction and reduced nasal congestion.

Dosage and Administration:

• Adults and Children Over 12 Years: Take 1 tablet every 4 to 6 hours as needed for symptom relief. Do not exceed 4 tablets in 24 hours.
• Children Under 12 Years: Consult a healthcare provider before use.
• Administration: Swallow the tablet whole with water. Taking with food may reduce the risk of stomach upset.

Side Effects:

• Common: Drowsiness, dizziness, dry mouth, nausea, and stomach upset.
• Serious: Allergic reactions such as rash, swelling, or difficulty breathing.
