Guaifenesin: Uses, Side Effects, and Drug Interactions

# Guaifenesin Overview Guaifenesin is a medicine that helps your body get rid of mucus when you have a cough caused by a cold, flu, or bronchitis. When you're sick, your body makes extra thick mucus in your chest and throat. This medicine makes that mucus thinner and easier to cough up, so you can clear your airways and feel better. It's often found in over-the-counter cough medicines that you can buy at any pharmacy without a prescription. When using guaifenesin, it's important to follow the dosage instructions on the package for your age and always check with a doctor if you have other health conditions or take other medicines. Keep this medicine out of reach of children and only give it to kids if the label says it's safe for their age. If your cough lasts for more than a week, gets worse, or you start coughing up blood, you should stop taking the medicine and talk to a doctor right away. Remember to drink plenty of water while taking this medicine because it works better when you stay hydrated.
