Cough
"WARNING - if you have taken this before &amp; get a new prescription, CHECK THE DOSAGE! My previous prescription (100 mg each) was &quot;take 2 capsules, 3 times per day&quot; and the NEW prescription is &quot;take 1 capsule, 3 times per day&quot; - Since I had taken it before I just looked at the drug NAME when I picked up the bottle &amp; didn&#039;t look at the dosage until I noticed the instructions said 1 CAPSULE.  In comparing the old expired 100 mg ones in my medicine cabinet  to the new 200 mg ones, the only visual difference is that the 200 mg ones are a little bigger. Agree with others that it doesn&#039;t last 8 hours, but I can&#039;t take codeine cough syrup &amp; it works better than DM."
