Read below: For an adult taking Mucinex (guaifenesin) dm the max dose is 4 tablets in 24 hours. Ideally you take it 1-2 tablets every 12 hours. To maximize its effectiveness, you should drink plenty of water. If it is Mucinex (guaifenesin) dm maximum strength then max dose is 2 tabs/24 hours by taking 1 tab every 12 hours.
