This is what I take. It all fits in a 4" x 6" silicon nylon pouch
1 -- Small first aid booklet
2 Extra large band aids
4 1 band aids
4 2 x 2 gauze pads
1 -- 6" x 6" gauze pad
2 -- antiseptic wipes in foil pkg.
6-- adhesive butterfly bandages
1 - splinter needle
2 scalpel blades in foil pkg.
4 safety pins; 2 small, 2 medium
8 -- Calcium carbonate antacid tablets
8 Acetaminophen tablets; dose = 2
8 Benadryl tablets; dose = 1-2
12 Ibuprofen tablets; dose = 1-4
12 -- Amoxycillin tablets
9 Aspirin tablets; dose = 1-3
6 - Imitrex (100 mg, migraine medication), dose = 1 then another if headache persists.
8 - Vicodin (5-500 mg, pain killer), dose = 1 every four hours for pain.

Weight of the foregoing is about 3 oz. Tablets are carried in 1.5" x 1.5" ziploc bags. I also carry tweezers, duct tape, bandanna, salt, antibiotic ointment, 2 oz of rubbing alcohol, hand sanitizer and a 2 oz prescription bottle containing more ibuprofen and antacids (my working supply) in other parts of my pack. On longer trips, I include more Imitrex, ibuprofen and antacids in resupply. The antacids also serve as a calcium supplement. I also take a multi-vitamin every day.
