I recently went to ER for terrible tooth pain. Was given rx for both penicillin vk 500 mg tabs as well as oxycodone/acetaminophen 5-325. I am taking 1 of each every 6 hours (sometimes 1.5 of the latter) as directed. Other than eating less due to pain and swelling in my mouth, my diet is otherwise unchanged. I smoke about half a pack a day, and am drinking just as much water as normal. My new symptoms are insomnia, yellow and cloudy urine, sweet smelling sweat, a semi sweet metallic taste in my mouth, and lowered sex drive. How concerned should I be?
