Haha! I brought my steroid drops from the faxed Rx's sent to my Toronto pharmacy, but I also didn't fill the T3. They kept insisting that they would provide me with the Rx in Vancouver if I ended up needing it as well, which thankfully I didn't.
Something like pain is really hard to predict. However, when I got my wisdom teeth taken out over a decade ago, the oral surgeon also told me to take ibuprofen around the clock for 3 days. I ended up filling the T3 script "just in case" back then and didn't end up needing them then, either.
So I just made sure I took the ibuprofen around the clock (every 4-6 hours) for 2 days post-op as PLEC advised. When you pre-emptively prevent swelling and pain, it is better controlled than waiting for the pain to occur and then trying to chase it. The patient instruction sheet also said to use regular Tylenol tabs around the clock...but the recent article I read within the last year stated that if therapeutic doses of ibuprofen (or some other standard NSAID like naproxen) alone isn't enough to relieve pain, there was no evidence for Tylenol + ibuprofen helping much more. So I skipped buying the regular Tylenol tabs, too. (I pretty much never take plain Tylenol...)
