I found these in my pill box at work and was going to give them to a co-worker as a pain reliever but could not find any information about them online. I went home and found out what they were - Chest Congestion and Cough Relief Tablets under the brand name of "Good Neighbor Pharmacy". The active ingredients are
Dextromethorphan HBr 20 mg (Cough Suppressant) and
Guaifenesin 400 mg (Expectorant).
Hope this helps!
