Decongestants are medications that are used to alleviate nasal congestion and reduce inflammation in the nasal passages. They work by narrowing the blood vessels in the nasal passages, which reduces swelling and allows more air to flow through. Some synonyms for the word "decongestants" include nasal sprays, sinus relief medications, congestion remedies, allergy relief medicines, and stuffy nose treatments. These medications can be prescribed or purchased over the counter and can be found in various forms, including tablets, capsules, liquids, or nasal sprays. It is essential to follow the instructions carefully when using decongestants to avoid any possible side effects, such as dizziness, headaches, or dry mouth.
