What should I do if I miss a dose of Ultracet?

If you are taking Ultracet on a regular schedule and miss a dose, take it as soon as you remember -- unless it is almost time for your next dose. In that case, skip the missed dose and resume your regular schedule. Do not take a double dose of Ultracet to make up for one you missed. Ultracet is a prescription pain medication that contains two drugs: tramadol and acetaminophen. It's important to note that Ultracet should be taken only when you are in pain, so you may not have the kind of regular dosing schedule you would if you were taking a drug like an antibiotic.
