GP-500: Side Effects, Overdose and Pregnancy Information

GP-500 is a decongestant and expectorant combination. The expectorant in GP-500 helps loosen the thick mucus that causes chest congestion. The decongestant in GP-500 is used to give relief from stuffy nose, runny nose, and ear congestion caused by allergies and or the common cold, or infection. GP-500 works by stimulating receptors in the body, mostly in the lining of the nose and sinuses, causing the blood vessel to contract. This results in less fluid to pass through into these linings. GP-500 helps relieve the symptoms of nasal congestion by reducing the production of mucus. This combination does not cure cold or allergy; instead it provides relief from the symptoms.
