"i have used the oc for 11 years. during that time i have only decreased my dosage. now, the op formula simply doesn&#039;t work. i take 2-3x the breakthrough pain medicines, i have added ibuprofen and naproxen to my regimen. i am going to have to increase my op dosage on my next visit because it simply doesn&#039;t work. thia new formula is ineffective. i&#039;m going to discuss switching to a different medication, but the oc used to work so well. i was able to go canoeing and walking in the woods. now i&#039;m back to missing work."
