I took Aleve (naproxen) around 11 am. This morning, it is now 4:30 pm, is it safe to take Advil. I pulled a muscle in my shoulder and damaged a rib?

NSAIDS. NSAIDs (the common over the counter anti-inflammatories) are good for muscle strains and overuse injuries. Aleve (naproxen) and Advil (ibuprofen) are common NSAIDs. Recommend you stick with one or the other. I like naproxen (Aleve) dosed 500 mg 2 times daily with food. Ibuprofen (Advil) is dosed 800 mg 3 times daily, so less convenient. Save $$ and buy naproxen (same as Aleve) but lower cost.
