Can I take Aspirin 300 and Tramadol together?

Drug interaction guide

Taking aspirin and tramadol together can increase the risk of bleeding, particularly in the stomach or gut. It may also increase the risk of side effects like dizziness, drowsiness, or feeling sick. Additionally, both medications can affect your kidney function, especially if you are dehydrated or have existing kidney issues.

Why this happens

Aspirin thins the blood and can irritate the lining of the stomach. While tramadol is an opioid-type painkiller, it can also slightly increase bleeding risk by affecting how platelets (blood-clotting cells) work. When used together, these effects add up. Both drugs are also processed or filtered by the kidneys, which can put extra strain on them.

What you should do

You can take these together if prescribed by your doctor, but use caution. Watch for signs of stomach irritation or bleeding, such as dark/tarry stools, coughing up blood, or severe stomach pain. Ensure you stay well-hydrated to protect your kidneys. If you are taking aspirin 300mg (a high dose) for pain, do not take other anti-inflammatories (like ibuprofen) at the same time. If you feel excessively drowsy or dizzy, avoid driving or operating machinery.
