Product Overview

Introduction of Sunward Allersin-F 4mg Tablet 10s (strip)

Sunward Allersin-F 4mg Tablet is an antihistamine medication containing Chlorpheniramine Maleate as its active ingredient, belonging to the first-generation antihistamine drug class that has been widely trusted in allergy management for decades. If you are someone who deals with sneezing, itchy eyes, or skin reactions, this is a medicine you may have come across before — and it is good to know what you are taking before you start. Like most antihistamines, it may cause drowsiness, dry mouth, dizziness, and blurred vision in some people, so it is worth being aware of how your body responds. This tablet is commonly available and straightforward to use, but as with any medicine, it is always best to follow your doctor's or pharmacist's advice to make sure it is right for you.

How to Take Sunward Allersin-F 4mg Tablet
Sunward Allersin-F 4mg Tablet should be taken orally, swallowed whole with a full glass of water, and can be taken with or without food — though taking it with food may help reduce the chance of an upset stomach. It is important to follow the dosage instructions provided by your doctor or as stated on the packaging, and you should avoid crushing or chewing the tablet unless advised otherwise by a healthcare professional. Do not take more than the recommended dose, and if you miss a dose, take it as soon as you remember — but skip it if it is almost time for your next scheduled dose.

Dosage of Sunward Allersin-F 4mg Tablet
The typical recommended dose for adults and children above 12 years is one tablet (4mg) taken three to four times daily, not exceeding 24mg in a 24-hour period. For children between 6 to 12 years, dosage should be guided by a healthcare professional, as it is generally lower and weight-dependent.

Shelf Life of Sunward Allersin-F 4mg Tablet
Sunward Allersin-F 4mg Tablet generally has a shelf life of 2 to 3 years from the date of manufacture, as indicated on the product packaging. Always check the expiry date printed on the blister pack or box before use, and do not consume the tablet if it has passed its expiration date, even if it appears unchanged in appearance.
