I carry aspirin in my bike bag. Ibuprofen too. A couple of those small sealed 2-capsule packs. They take up almost no room. I also carry a small 0.25 oz sampler tube of triple anti-biotic ointment. And a couple of bandaids. The whole lot adds very little weight and fits into little nooks & crannies around my spare tube, multi-tool, and other odds & ends.
