doxylamine succinate + ibuprofen

Doxylamine succinate + ibuprofen is a combination of two small molecule drugs. Doxylamine succinate is an ethanolamine-derivative antihistamine with pronounced sedative and anticholinergic properties, commonly used as a short-term sleep aid and for relief of allergy or cold symptoms. It acts primarily as a histamine H1 receptor antagonist, blocking the action of histamine in the body to reduce allergic symptoms and induce sedation. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, leading to decreased synthesis of prostaglandins involved in pain, inflammation, and fever. The combination may be used off-label for symptomatic relief where both analgesia/anti-inflammatory effects (from ibuprofen) and sedative/antihistaminic effects (from doxylamine) are desired[5][6][7]. There are no known significant interactions between these two drugs when taken together[1][3].
