Drug Overview

Low Dose Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that comes in a low dosage of 81 mg, designed to provide temporary relief from minor aches and pains. It features an enteric safety coating, which helps protect your stomach from irritation. While it can be effective for managing discomfort, it's important to note that it is not intended for quick relief of headaches or other symptoms that require immediate attention due to its delayed action.

Before starting an aspirin regimen, it's advisable to consult with your doctor, as aspirin may not be suitable for everyone. This product is comparable to Bayer® Low Dose Aspirin but is not manufactured or distributed by Bayer AG.
