Blood thinners are medications designed to enhance blood flow through veins and arteries, helping prevent clot formation. They are commonly prescribed to treat heart conditions, reduce stroke risk, and manage clot-related disorders. While they effectively lower the risk of heart attack and stroke, they may have side effects. It's important to understand how these drugs work and consult your doctor before starting treatment. These medicines work by either preventing new clots or slowing the growth of existing ones, but they do not dissolve clots already formed.
Types of blood thinners:
Blood thinners fall into two main categories: anticoagulants and antiplatelets. Anticoagulants inhibit clot formation by preventing blood from becoming sticky. Some common medications include:
Dabigatran (Pradaxa)
Apixaban (Eliquis)
Fondaparinux (Arixtra)
Edoxaban (Savaysa)
Rivaroxaban (Xarelto)
Heparin (Innohep, Fragmin, Lovenox)
Warfarin (Jantoven, Coumadin)
The potent anticoagulants like Heparin and Fondaparinux are administered via injection or IV. Antiplatelet drugs such as
Clopidogrel (Plavix)
Aspirin
Prasugrel (Effient)
Dipyridamole (Persantine)
prevent platelets from sticking but do not dissolve existing clots. They primarily inhibit clot growth and formation.
These medications do not thin the blood directly but prevent it from becoming too thick. They work by affecting Vitamin K, essential for producing clotting factors. Anticoagulants reduce Vitamin K activity, hindering clot formation, while antiplatelets decrease platelet aggregation. Antiplatelets are generally milder and are used for preventing future clot risks.
Possible side effects:
When on blood thinners, caution is vital as injuries may bleed longer to heal. Symptoms indicating complications include:
Heavy menstrual bleeding
Blood in urine or stool
Nose or gum bleeding
Vomiting blood
Coughing up blood
Weakness or dizziness
Severe headache
Abdominal pain.
Always discuss safety precautions with your healthcare provider while on these medications. Limit intake of Vitamin K-rich leafy greens, and avoid starting new medications without consulting your doctor first.
