Tramadol is used to relieve moderate to moderately severe pain. Tramadol extended-release tablets and capsules are only used by people who are expected to need medication to relieve pain around-the-clock. Tramadol is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.

Tramadol comes as a tablet, an extended-release (long-acting) tablet, and an extended-release (long-acting) capsule to take by mouth. The regular tablet is taken usually with or without food every 4 to 6 hours as needed. The extended-release tablet and extended-release capsule should be taken once a day. Take the extended-release tablet and the extended-release capsule at about the same time of day every day. If you are taking the extended-release capsule, you may take it with or without food. If you are taking the extended-release tablet, you should either always take it with food or always take it without food. Take tramadol exactly as directed. Do not take more medication as a single dose or take more doses per day than prescribed by your doctor. Taking more tramadol than prescribed by your doctor or in a way that is not recommended may cause serious side effects or death.
Your doctor may start you on a low dose of tramadol and gradually increase the amount of medication you take, not more often than every 3 days if you are taking the regular tablets or orally disintegrating tablets or every 5 days if you are taking the extended-release tablets or extended-release capsules.
Do not stop taking tramadol without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking tramadol, you may experience withdrawal symptoms such as nervousness; panic; sweating; difficulty falling asleep or staying asleep; runny nose, sneezing, or cough; pain; hair standing on end; chills; nausea; uncontrollable shaking of a part of your body; diarrhea; or rarely, hallucinations (seeing things or hearing voices that do not exist).
Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your body’s response to tramadol.
Before having any laboratory test (especially those that involve methylene blue), tell your doctor and the laboratory personnel that you are taking tramadol.
Do not let anyone else take your medication. Tramadol is a controlled substance. Prescriptions may be refilled only a limited number of times; ask your pharmacist if you have any questions.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
