Drug Overview

Guaifenesin extended-release tablets are a type of expectorant that contain 1200 mg of the active ingredient guaifenesin. This medication is designed to help loosen phlegm (mucus) and thin bronchial secretions, making it easier for you to clear your airways and have more productive coughs. It effectively relieves chest congestion by thinning and loosening mucus, which can help you feel more comfortable when you're dealing with respiratory issues.

These tablets are available in both immediate and extended-release forms, allowing for prolonged relief from congestion. Guaifenesin is comparable to the active ingredient found in Maximum Strength Mucinex®, making it a trusted option for those seeking to alleviate symptoms associated with mucus buildup.

Uses

This medication is designed to help you breathe easier by loosening phlegm (mucus) and thinning bronchial secretions. By doing so, it helps clear out bothersome mucus from your bronchial passageways, making your coughs more productive. This can be particularly helpful if you're dealing with respiratory issues that involve excess mucus.

Rest assured, there are no known teratogenic effects (which means it doesn't cause birth defects) associated with this medication, making it a safer option for those concerned about such risks.

Dosage and Administration

When taking this medication, it's important to swallow the extended-release tablet whole. Do not crush, chew, or break it, as this can affect how the medicine works. Make sure to take it with a full glass of water, and you can take it at any time, regardless of meals.

For adults and children aged 12 years and older, the recommended dose is one extended-release tablet every 12 hours. Be careful not to take more than two tablets in a 24-hour period. If your child is under 12 years old, this medication is not suitable for them, so please avoid using it.
