Important information about tramadol

You should not take tramadol if you have ever been addicted to drugs or alcohol.
Seizures (convulsions) have occurred in some people taking tramadol. You may be more likely to have a seizure while taking tramadol if you have a history of seizures or head injury, a metabolic disorder, or if you are taking certain medicines such as antidepressants, muscle relaxers, or medicine for nausea and vomiting.
Seek emergency medical attention if you think you have used too much of this medicine. A tramadol overdose can be fatal. Overdose symptoms may include drowsiness, shallow breathing, slow heartbeat, extreme weakness, cold or clammy skin, feeling light-headed, fainting, or coma. Tramadol may be habit-forming.
Tell your doctor if you feel the medicine is not working as well in relieving your pain. Do not take more than 300 milligrams of tramadol in one day. Never share tramadol with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
Tramadol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Do not stop using tramadol suddenly, or you could have unpleasant withdrawal symptoms such as anxiety, sweating, nausea, diarrhea, tremors, chills, hallucinations, trouble sleeping, or breathing problems. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.
Do not crush the tramadol tablet. This medicine is for oral (by mouth) use only. Powder from a crushed tablet should not be inhaled or diluted with liquid and injected into the body. Using this medicine by inhalation or injection can cause life-threatening side effects, overdose, or death.
