Before Your Procedure

Ask about your medications

You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop taking. We have included some common examples below.

Anticoagulants (blood thinners)

If you take a blood thinner (medication that affects the way your blood clots), ask the doctor performing your procedure what to do. Their contact information is listed at the end of this resource. Whether they recommend you stop taking the medication depends on the reason you’re taking it.

Do not stop taking your blood thinner medication without talking with your doctor.

Examples of Blood Thinners
apixaban (Eliquis®) dalteparin (Fragmin®) meloxicam (Mobic®) ticagrelor (Brilinta®)
aspirin dipyridamole (Persantine®) nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil®) or naproxen (Aleve®) tinzaparin (Innohep®)
celecoxib (Celebrex®) edoxaban (Savaysa®) pentoxifylline (Trental®) warfarin (Coumadin®)
cilostazol (Pletal®) enoxaparin (Lovenox®) prasugrel (Effient®)  
clopidogrel (Plavix®) Fondaparinux (Arixtra®) rivaroxaban (Xarelto®)  
dabigatran (Pradaxa®) heparin (shot under your skin) sulfasalazine (Azulfidine®, Sulfazine®)  

Please read our resource Common Medications Containing Aspirin and Other Nonsteroidal Anti-inflammatory Drugs (NSAIDs). It has important information about medications you’ll need to avoid before your procedure and what medications you can take instead.

Medications for diabetes

If you take insulin or other medications for diabetes, ask the doctor who prescribes the medication what you should do the morning of your procedure. You may need to change the dose before your procedure.

Diuretics (water pills)

If you take any diuretics (medications that make you urinate more often), ask the doctor performing your procedure what to do. You may need to stop taking them the day of your procedure. Diuretics are sometimes called water pills. Some examples are furosemide (Lasix®) and hydrochlorothiazide.

Arrange for someone to take you home

You must have someone 18 years or older take you home after your procedure. If you don’t have someone to do this, call one of the agencies below. They will send someone to go home with you. There’s usually a charge for this service, and you will need to provide transportation.
