Nausea or vomiting, constipation, lightheadedness, dizziness, drowsiness and headaches are common side effects of tramadol, states WebMD. In severe and rare cases, patients may experience, fainting, seizures, shallow breathing and unusual drowsiness or difficulty waking up. Some symptoms may lessen as the patient adjusts to the medication over time.
Tramadol is sold under various brand names, often in a 50mg tablet. It is used to treat moderate pain and may increase serotonin, notes WebMD. This drug can have severe side effects when interacting with other medications, such as other pain medications. MAO inhibitors can cause serious and even fatal interactions and should also be avoided for two weeks before starting tramadol. Other drugs that increase serotonin, such as certain anti-depressants, increase the risk of serotonin syndrome or toxicity.
Some medications for treating HIV or seizures and some antibiotics can affect the removal of tramadol, thus affecting how the drug works, according to WebMD. Serious side effects of tramadol could appear if taken with other products that have similar side effects, such as allergy pills, cold medicine, alcohol, psychiatric medications, medicine for anxiety or sleep, and muscle relaxants. This drug may also cause false test results with certain lab tests. It is important to inform all doctors and medical personnel when taking this medication, as well as any other medication being taken along with it.
