Why is this medication prescribed?

Q-Tussin is a brand name for a cough syrup that typically contains guaifenesin as one of its active ingredients. Guaifenesin is an expectorant, which means it helps loosen and thin mucus in the airways, making it easier to cough up. This can be useful in conditions where there is excessive mucus production, such as in respiratory infections or conditions like bronchitis.

  • Timing: Take the medication as directed by your healthcare provider or according to the instructions on the packaging. It may be recommended to take it with or without food.
  • Hydration: It’s important to stay well-hydrated when using medications like guaifenesin, as adequate fluid intake can help enhance its effectiveness in loosening mucus.
