Blood thinners are crucial in preventing and treating various cardiovascular and circulatory conditions. There are two main types of medications — anticoagulants and antiplatelets — that a doctor may recommend depending on the condition to be treated.
Blood thinners work by preventing blood from clotting.
They can help reduce the risk of dangerous blood clots forming that can lead to serious or life threatening health problems, such as stroke, deep vein thrombosis (DVT), and pulmonary embolism (PE).
In this article, we will explore the different types of blood thinners, common blood thinner brands, their uses, and how to take them.
Blood thinners are a category of medication that helps prevent the formation of blood clots within the bloodstream.
Doctors may refer to clots as a thrombosis. Depending on the location in the body and whether the clot blocks blood vessels, a thrombosis can be life threatening.
Two primary types of blood thinners can help stop the formation of blood clots:
- Anticoagulants: These work by preventing the formation of blood clots. They achieve this by affecting proteins involved in blood clotting, such as fibrin and thrombin. Anticoagulants may come in a pill form or as an injection.
- Antiplatelets: These medications target platelets, which play a
key role in blood clot formation. Antiplatelets usually come in pill form.
Despite often being referred to as “blood thinners,” these medications do not actually thin the blood. Instead, they slow the body’s ability to form clots.
It’s important to note that they do not break up existing blood clots but can help prevent new ones from forming or slow the growth of existing ones.
A doctor will select the most appropriate blood thinner for the specific condition being treated.
Medications include the following:
Anticoagulants
Antiplatelets
Doctors may prescribe blood thinners for the following conditions:
- atrial fibrillation (AFib)
- DVT
- PE
- coronary artery disease (CAD)
- peripheral artery disease (PAD)
They might also prescribe them before or after heart valve replacement surgery or other surgeries that increase the risk of blood clots.
Other risk factors for blood clots include:
- physical trauma
- prolonged immobility
- having a family history of blood clots or blood clotting disorders
- taking certain cancer treatments
Taking blood thinners correctly and following a doctor’s instructions helps ensure their effectiveness and safety.
Here are some important guidelines:
- Follow the prescribed dosage: Always take the medication as directed by your doctor. Never alter the dosage without their guidance. People of advanced age
may take lower doses due to their risk of falls. Blood that cannot clot as well as usual can be dangerous if a person has an injury. - Take it at the same time daily: To maintain a consistent level of the medication in the blood, it is important to take it at the same time every day.
- Monitor your diet: It is important to maintain a consistent diet while on blood thinners. Discuss any significant dietary changes with a healthcare professional. For some medications, such as warfarin, people may need to be mindful of their vitamin K intake.
- Over-the-counter (OTC) medications and supplements: Consult a doctor before taking any OTC medications or supplements, as they may interact with blood thinners.
- Monitor INR levels, if necessary: For people taking warfarin, regular blood tests, such as the international normalized ratio (INR), are necessary to measure how long it takes a person’s blood to clot.
The duration a person needs to take blood thinners varies depending on medical conditions and individual risk factors.
Some people may need blood thinners for a few months, while others may require long term therapy.
A doctor will determine the appropriate length of time based on an individual basis.
Some common side effects of antiplatelet medications include:
- nosebleeds
- easy bruising
- anemia
- aspirin-induced asthma
- nasal polyps
- ecchymosis, or skin discoloration due to bleeding beneath the skin
- blood in the urine
- a low blood platelet count
Some common side effects of anticoagulant medications, such as
- hemorrhages
- nausea
- vomiting
- abdominal pain
- bloating
- flatulence
- an altered sense of taste
Blood thinners increase the risk of excessive bleeding, particularly for at risk individuals or people undergoing surgery. People should seek emergency help for excessive bleeding.
How to manage side effects
Consider the following measures:
- Stay cautious: Be mindful of your surroundings and activities to prevent injuries that could lead to bleeding.
- Avoid alcohol: Excessive alcohol consumption may increase the effect of the drug and the risk of bleeding. Consult with a doctor for guidance on alcohol’s effect on a specific type of medication.
- Use soft toothbrushes: To reduce the risk of gum bleeding, use a soft toothbrush for oral hygiene.
- Regular monitoring: Regularly follow up with a healthcare professional to monitor for potential side effects and adjust treatment or dosage as necessary.
Long-term side effects and complications can include:
- Osteoporosis: Some blood thinners, particularly heparin and warfarin, when taken long term, may contribute to reduced bone density and an increased risk of fractures.
- Gastrointestinal issues: Chronic use of blood thinners can lead to gastrointestinal problems, such as ulcers in the stomach or intestines.
- Hemorrhagic stroke: Blood thinners can increase the risk of a hemorrhagic stroke, which occurs when a blood vessel in the brain ruptures. It is a medical emergency.
If people experience any of the following symptoms while on blood thinners, seek immediate medical attention:
- uncontrolled bleeding
- blood in the urine or stool
- a severe headache, weakness, numbness, or confusion
- severe abdominal pain
- coughing up blood
- frequent nosebleeds or heavy menstrual bleeding
Additionally, it is vital to regularly attend follow-up appointments with a healthcare professional to monitor treatment effectiveness and discuss any concerns or side effects.
Blood thinners help prevent blood clots and treat various cardiovascular and circulatory conditions. If a person has certain risk factors for clotting, such as physical trauma, blood thinners can help prevent serious complications.
The two primary types of blood thinners are anticoagulants and antiplatelets. Doctors prescribe these medications for conditions such as atrial fibrillation, deep vein thrombosis, and heart valve replacement. Always follow a doctor’s instructions when taking them.
While blood thinners can be lifesaving, they also come with risks for potential long-term side effects and complications. If an individual experiences severe symptoms or side effects, consult a doctor or seek emergency help.
Attending regular follow-up appointments when taking blood thinners is crucial to ensure blood thinners remain effective and safe.
