Cangrelor Medication: Uses, Dosage, and Side Effects Explained
Summary of Key Points
Cangrelor is a fast-acting medication used to prevent blood clots in individuals with certain heart conditions. It is commonly administered during procedures like percutaneous coronary intervention (PCI) to reduce the risk of complications such as heart attacks or strokes. Cangrelor works by preventing platelets (a type of blood cell) from clumping together. Always consult your healthcare provider before starting or adjusting your dose of Cangrelor.

Administration Instructions for Cangrelor
Cangrelor is administered by a healthcare professional as an intravenous (IV) infusion, typically during procedures like PCI to prevent blood clots. The medication works quickly and is stopped once the procedure is complete. Inform your healthcare provider of any other medications you are taking, as Cangrelor can interact with other drugs. If you have concerns, consult with one of our telemedicine providers.
Cangrelor Side Effects and Adverse Reactions
Like all medications, Cangrelor can cause side effects. Some are common, while others are rare but more serious. If you experience any side effects, contact your healthcare provider immediately. You can also reach out to one of our telemedicine providers for advice.
Common Side Effects
Bleeding: Cangrelor increases the risk of bleeding, which may occur at the IV site or in other areas of the body.
Shortness of Breath: Some patients may experience difficulty breathing during or after the procedure.
Less Common Side Effects
Low Blood Pressure (Hypotension): Cangrelor can cause a drop in blood pressure, leading to dizziness or fainting.
Allergic Reactions: Rarely, patients may develop an allergic reaction, which can include rash, itching, or swelling.
Contraindications for Cangrelor
A contraindication is a specific situation or condition where a medication should not be used because it could cause harm. If you have any of the following conditions, Cangrelor may not be safe for you.
Active Bleeding
Cangrelor is an antiplatelet medication, meaning it prevents blood clots. If you are actively bleeding, taking Cangrelor could worsen the bleeding and make it difficult to stop.
Severe Bleeding Disorders
If you have a condition like hemophilia or thrombocytopenia (low platelet count), Cangrelor could increase your risk of severe bleeding because it further reduces your blood’s ability to clot.
Hypersensitivity to Cangrelor
If you have had an allergic reaction to Cangrelor or any of its components, taking it again could lead to serious allergic reactions, including anaphylaxis, which is a life-threatening condition.
Always inform your healthcare provider about any medical conditions you have before starting Cangrelor. If you have concerns, you can schedule a telemedicine appointment with one of our providers to discuss your options.
Drug to Drug Interactions with Cangrelor
Some medications can interact with Cangrelor, which may increase your risk of side effects or reduce the effectiveness of either drug. Be sure to tell your healthcare provider about all the medications you are taking, including over-the-counter drugs and supplements.
Clopidogrel (Plavix)
Taking Clopidogrel with Cangrelor can reduce the effectiveness of Clopidogrel, as both medications work to prevent blood clots. These medications should not be used together.
Prasugrel (Effient)
Similar to Clopidogrel, Prasugrel should not be used with Cangrelor because they both affect platelet function and could increase the risk of bleeding.
Ticagrelor (Brilinta)
Like Clopidogrel and Prasugrel, Ticagrelor should not be used with Cangrelor due to the increased risk of bleeding and reduced effectiveness of the medications.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Medications like ibuprofen (Advil, Motrin) or naproxen (Aleve) can increase your risk of bleeding when taken with Cangrelor.
If you are taking any of these medications, consult with your healthcare provider about potential alternatives or adjustments to your treatment. You can also schedule a telemedicine visit with one of our providers to get personalized advice.
Cangrelor in Pregnancy
Is it safe to take Cangrelor when pregnant?
The safety of Cangrelor during pregnancy has not been extensively studied. It is classified as a Category C drug by the FDA, meaning that while animal studies have shown potential risks to the fetus, there are no well-controlled studies in humans. If you are pregnant or planning to become pregnant, it is essential to discuss the potential risks and benefits of using Cangrelor with your healthcare provider. They may recommend alternative treatments that are considered safer during pregnancy.
Cangrelor While Breastfeeding
Is it safe to take Cangrelor while breastfeeding?
There is limited information on whether Cangrelor passes into breast milk. Due to the possibility of serious side effects in a nursing infant, it is generally advised to avoid breastfeeding while taking Cangrelor. If you are breastfeeding or plan to breastfeed, consult your healthcare provider to explore safer alternatives.
Estimated Cost of Cangrelor Medication
The cost of a 30-day supply of Cangrelor without insurance can vary. However, with a GoodRX coupon, the price typically ranges between $1,500 and $2,000. Prices may differ depending on the pharmacy and location, so it’s a good idea to check with your pharmacy for the most accurate pricing.
Possible Alternatives to Cangrelor
If you are taking Cangrelor for any of the following conditions, there may be alternative treatments or lifestyle changes that could be beneficial. Always consult your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine visit with one of our providers to discuss these options in more detail.
- Acute Coronary Syndrome (ACS): Alternatives include other antiplatelet medications such as Clopidogrel (Plavix) or Ticagrelor (Brilinta). Lifestyle changes, including quitting smoking, adopting a heart-healthy diet, and engaging in regular exercise, can also help manage ACS.
- Myocardial Infarction (Heart Attack): Common treatments include aspirin, beta-blockers, and statins. Cardiac rehabilitation and lifestyle modifications, such as stress reduction and dietary improvements, can also be beneficial.
- Unstable Angina: Medications like nitroglycerin, beta-blockers, and calcium channel blockers are often used. Lifestyle changes, including weight management and regular physical activity, can help alleviate symptoms.
- Percutaneous Coronary Intervention (PCI): Alternatives to Cangrelor during PCI include Clopidogrel (Plavix) or Prasugrel (Effient). Your doctor may also recommend lifestyle changes to help prevent future heart issues.
- Coronary Artery Disease (CAD): Statins, ACE inhibitors, and beta-blockers are commonly prescribed. Lifestyle changes, such as following a low-fat diet, exercising regularly, and quitting smoking, can help manage CAD.
- Thrombosis: Other anticoagulants, such as warfarin (Coumadin) or direct oral anticoagulants (DOACs) like apixaban (Eliquis), may be considered. Staying active and avoiding prolonged periods of immobility can also reduce the risk of thrombosis.
- Atherosclerosis: Statins, aspirin, and blood pressure medications are frequently used. A diet rich in fruits, vegetables, and whole grains, along with regular physical activity, can help slow the progression of atherosclerosis.
- Ischemic Heart Disease: Medications such as beta-blockers, ACE inhibitors, and statins are often prescribed. Lifestyle changes, including stress management, a heart-healthy diet, and regular exercise, can also be beneficial.
- Stroke: Anticoagulants like warfarin (Coumadin) or DOACs may be used. Managing blood pressure, controlling diabetes, and quitting smoking are important lifestyle changes to help prevent strokes.
- Peripheral Artery Disease (PAD): Medications like Cilostazol (Pletal) or aspirin may be prescribed. Regular exercise, smoking cessation, and maintaining a healthy weight can also improve PAD symptoms.
Recent Updates on Cangrelor Research
Recent studies have focused on the use of Cangrelor in specific patient populations, particularly those undergoing high-risk percutaneous coronary interventions (PCI). Research suggests that Cangrelor can be especially beneficial for patients who are unable to take oral antiplatelet medications due to emergency situations or difficulty swallowing. Ongoing studies are also investigating the long-term safety of Cangrelor when used in combination with other anticoagulants.
As new research continues to emerge, staying informed about the latest developments is important. If you have any questions about how this research may impact your treatment, consider scheduling a telemedicine appointment with one of our providers to discuss your options.
