The typical recommended dosage of Mucinex (guaifenesin) for adults is as follows:
- Regular strength (600 mg extended-release tablets): Take 1 to 2 tablets every 12 hours with a full glass of water as needed. Do not exceed 4 tablets in 24 hours.
- Maximum strength (1200 mg extended-release tablets): Take 1 tablet every 12 hours with a full glass of water as needed. Do not exceed 2 tablets in 24 hours.
For Mucinex DM tablets (which contain guaifenesin and dextromethorphan):
- Take 1 or 2 tablets every 12 hours as needed. Do not take more than 4 tablets in 24 hours.
Always take doses with water, and do not chew, cut, or crush extended-release tablets to avoid interfering with medication release and effects. Check product labels for specific instructions and consult a healthcare professional if unsure or if giving to children.
