Drug Overview

PHARBEST is a type of low-dose aspirin that contains 81 mg of aspirin in each enteric-coated tablet. It is classified as a nonsteroidal anti-inflammatory drug (NSAID) and is primarily used for the temporary relief of minor aches and pains. The enteric coating helps protect your stomach from irritation, making it a gentler option for those who may be sensitive to regular aspirin.

While PHARBEST can help alleviate discomfort, it's important to note that it is not intended for fast relief of headaches or other symptoms that require immediate attention, as it has a delayed action. If you're considering using this product, especially for heart-related purposes, it's advisable to consult with your doctor or healthcare provider.

Uses

This product is designed to help you find temporary relief from minor aches and pains, but it's important to note that it may not provide quick relief for headaches or other symptoms that require immediate attention. If you're considering using this product, it's a good idea to talk to your doctor about any other potential uses it may have for you.

Dosage and Administration

When taking this medication, it's important to drink a full glass of water with each dose to help with absorption. For adults and children aged 12 years and older, you should take 4 to 8 tablets every 4 hours. However, make sure not to exceed 48 tablets in a 24-hour period unless your doctor has instructed you otherwise.
