Cold medications are over-the-counter products designed to relieve symptoms associated with the common cold, such as congestion, cough, and sore throat. They often contain a combination of ingredients like antihistamines, decongestants, cough suppressants, and pain relievers to target specific symptoms. These medications come in various forms, including tablets, liquids, and nasal sprays. It's important to read labels carefully, as some products may contain multiple active ingredients, which can lead to unintentional overdosing if combined with other medications. Always consult a healthcare professional if unsure about which cold medication to use.
