Summarize this article in one sentence.
Mucus thinning medications like guaifenesin (Mucinex) can help reduce phlegm that causes coughing and throat irritation. If you're looking to clear your throat, look for such medications at your local supermarket or pharmacy. Take the meds as directed on the container. If you're concerned about over-the-counter medication interacting with any prescription meds you're on, talk to your doctor or pharmacist. Saline sprays and nasal drips can be purchased over-the-counter at your local drug store. They tend to be fairly effective in clearing out phlegm and other irritants that cause throat irritation.  If you're using a spray or drops, use as directed on the container. Ask a doctor or pharmacist if you have any additional questions.  If you're using a nasal irrigation system that requires squirting water into the nose, always use sterile water. Microorganism found in tap water can get into the brain through the nose, causing health problems and even death. Over-the-counter pain medications like acetaminophen and ibuprofen can ease pain caused by a sore throat. This can reduce symptoms like coughing and wheezing, which can make a clogged throat worse. As always, ask your doctor or pharmacist if you have any questions about the medication.

Summary:
Take mucus-thinning medication. Use saline nasal sprays. Try over-the-counter pain medications if your throat is sore.
