I am in agreement with not using medications like "Tylenol Cold & Sinus". If you have pain or a fever, take tylenol or ibuprofen......
As far as pain relief and side effects are concerned, many people are intolerant (think they are allergic) to codeine. Makes them nauseated. Hydrocodone (vicodin) or oxycodone (percocet) may be a better choice. HOWEVER, you really will need to have a relationship with your doctor for a prescription.

Just a thought!
