Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to tramadol, other opioid analgesics or acetaminophen. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy—Tramadol and acetaminophen has not been studied in pregnant women. However, studies in animals have shown that tramadol and acetaminophen causes birth defects and other problems. Before taking this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.
Too much use of an opioid during pregnancy may cause the fetus to become dependent on the medicine. This may lead to withdrawal side effects in the newborn baby. Newborn seizures, symptoms of withdrawal from opioids, death of the fetus and still birth have been reported.
Breast-feeding—Tramadol and acetaminophen pass into breast milk and may cause unwanted side effects in nursing babies. It may be necessary for you to take another medicine or to stop breast-feeding during treatment. Be sure you have discussed the risks and benefits of the medicine with your doctor.
Children—Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of tramadol and acetaminophen in children up to 16 years of age with use in other age groups.
Older adults—This medicine has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults.
Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking tramadol and acetaminophen, it is especially important that your health care professional know if you are taking any of the following:
- Anticoagulants (e.g., Coumadin [blood thinners])—Tramadol and acetaminophen may increase the amount of blood thinners in your blood, which can cause problems with bleeding.
- Alcohol and products with alcohol in them—Taking these medicines with tramadol and acetaminophen may cause problems with your liver.
