Taking dipyridamole with other medicines and herbal supplements

There are some medicines that can affect how dipyridamole works.

Tell your doctor if you're taking:

• other medicines to prevent blood clots, such as low-dose aspirin, clopidogrel, ticagrelor, warfarin, dabigatran, apixaban or rivaroxaban
• medicines for high blood pressure, such as bisoprolol, ramipril or furosemide
• indigestion medicines, such as famotidine, proton pump inhibitors like omeprazole, or antacids that contain magnesium or aluminium
• medicines used to treat myasthenia gravis

Taking dipyridamole with painkillers

You can take paracetamol together with dipyridamole if you need a painkiller.

Do not take aspirin for pain relief (300mg tablets) or ibuprofen while you're taking dipyridamole unless a doctor has said it's OK to. They increase the risk of bleeding.

To prevent blood clots, your doctor may prescribe daily low-dose aspirin (75mg tablets) to take together with dipyridamole.

Taking dipyridamole with indigestion medicines

Some indigestion medicines, such as omeprazole, may reduce the effect of dipyridamole. This is important if you're taking dipyridamole as tablets or liquid, but it's not a problem if you're taking capsules.

If you need to take indigestion medicines, do not take them at the same time of day as dipyridamole tablets or liquid. Take them 2 to 3 hours before or after your dose of dipyridamole.
