Acetaminophen combinations are used to treat pain, fever, and cold symptoms. They also have other uses, such as managing migraines and sinus pressure. These medications work by combining acetaminophen, which reduces pain and fever, with other active ingredients that target specific symptoms, such as congestion, sleeping difficulties, or inflammation. You can find these medications in different forms, including oral tablets, capsules, and liquid solutions. Examples include acetaminophen / aspirin / caffeine (Excedrin Migraine), acetaminophen / diphenhydramine (Tylenol PM), and acetaminophen / dextromethorphan / doxylamine (NyQuil). These combinations help you manage multiple symptoms with one medication.
