guaifenesin
Summary
Guaifenesin is used to relieve chest congestion, which is a feeling of tightness or fullness in the chest, associated with colds, bronchitis, and other respiratory conditions. It helps make coughing up mucus easier, which can improve breathing and reduce coughing.
Guaifenesin works by thinning mucus, which is a thick fluid produced in the airways, making it less sticky and easier to cough up. This helps clear congestion and improves breathing by allowing the body to expel mucus more effectively.
For adults, the usual dose of Guaifenesin is 200 to 400 mg every 4 hours as needed, not exceeding 2,400 mg per day. It is taken orally, which means by mouth, and can be taken with or without food.
Common side effects of Guaifenesin include nausea, which is a feeling of sickness with an inclination to vomit, vomiting, and dizziness, which is a sensation of spinning or losing balance. These effects are usually mild and temporary.
Guaifenesin should not be used if you are allergic to it, which means having a reaction like rash or swelling. It's not recommended for children under 4 years old without medical advice. Always follow your doctor's guidance regarding its use.
