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
Back to contentsYou 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.

Patient picks for Drug interactions

Treatment and medication
Can I take Amlodipine and Citalopram together?
Taking amlodipine and citalopram together may increase the risk of developing an abnormal heart rhythm. While both are commonly prescribed together, they can both affect the electrical activity of your heart. In rare cases, this can lead to a serious condition called QT prolongation, where the heart muscle takes longer than normal to recharge between beats. This can cause palpitations, dizziness, or fainting.
