Interactions

Alteplase/Anticoagulants

This information is generalized and not intended as specific medical advice. Consult your healthcare professional before taking or discontinuing any drug or commencing any course of treatment.

Medical warning:

Serious. These medicines may interact and cause very harmful effects. Contact your healthcare professional (e.g. doctor or pharmacist) for more information.

How the interaction occurs:

Both alteplase and anticoagulants decrease your body's ability to make blood clots.

What might happen:

You may experience an increased chance for bleeding including bleeding from your gums, nosebleeds, unusual bruising, dark stools, or bleeding from injection sites.

What you should do about this interaction:

Alteplase is a medicine that is used in a hospital to treat strokes, heart attacks, and blood clots in the lungs. If you need to be treated for a stroke and you use an anticoagulant (a "blood thinner"), your doctor may want to use a different medicine instead of alteplase. If you need to be treated for a heart attack or a blood clot in your lungs and you use an anticoagulant, your doctor will need to monitor you more closely. Be sure to let your healthcare professionals (e.g. doctor or pharmacist) and your family members know that you are taking an anticoagulant, so that emergency room personnel can treat you properly.Your healthcare professionals may already be aware of this interaction and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.
