What medication for blood clots?

Are you feeling like a ticking time bomb ready to explode from a blood clot? Fear not, my friend! In this article, I will give you the low-down on all the medications available to manage these pesky little bloodsuckers.

Blood Clots and Why They’re a Problem

First off, let’s discuss what exactly is going on inside your body when blood clots form. Simply put, it means that platelets (tiny disc-shaped cells in your bloodstream) stick together and create a “plug” at the site of an injury to stop bleeding. However, sometimes those plugs can become too large or form where they’re not needed – which creates issues with circulation and leads to serious conditions such as deep vein thrombosis (DVT), strokes, heart attacks… oh my! This is why managing blood clots is so important.

Heparin: The OG Anticoagulant

Moving on to our first medication: Heparin. If there were an anticoagulation hall of fame – heparin would undoubtedly be its MVP (Most Valuable Player) titleholder.

  • Heparin comes in two forms:

    • Unfractionated heparin (UFH)
    • Low molecular weight heparins (LMWH)
  • How does it work?

    • It stops new clots from forming by inhibiting the functionality of certain enzymes


  • Proven effectiveness over decades
  • Can be used pre-surgery/procedure
  • Rapidly reversibly with protamine sulfate if necessary


  • Requires constant monitoring through lab test called PTT & dose adjustments
  • May also cause life-threatening side effects including HIT (heparin-induced thrombocytopenia) –a condition caused by causing antibodies against itself within one’s own immune system.

Warfarin: The anticoagulation ‘Gandalf’

Warfarin – the archaic legend of anticoagulants. Think of it as the “You shall not pass” Gandalf. This medication has been around for decades and is still prescribed today thanks to its reliability in preventing clots from forming by inhibiting elements necessary for clot formation.

  • How does it work?
    • It blocks Vitamin K, which is essential in producing various blood-clotting agents


  • Knows how to party— aka rejoices with all other medications at every holiday season because he can be combined with any


  • It takes days to begin working
  • Can cause a plethora of severe side effects including bleeding gums or necrosis (death) on your skin!
    Talk about leaving an impression…

Direct Oral Anticoagulants (Doacs): The Bouncer To Clots

Nowadays, we have novel oral anticoagulants (NOACs) available —otherwise known as direct oral anticoagulants (DOACs) that continue to prove themselves as serious contenders against Heparin & Warfarin.

These guys intend only one thing, making sure no unwanted or uninvited guests make it past their club doors(a.k.a blood vessels)

There are four approved DOACs drugs available: Apixaban Eliquis®, Dabigatran Pradaxa®, Edoxaban Savaysa® and Rivaroxaban Xarelto® each has unique pros and cons offers based on your specific needs but they all share similar mechanisms such as inhibition of thrombin factor activation inhibited fibrin generation.

For those who love details and data you may see below table composed just so you get an idea 😉

Class Examples Dose interval Follow-up tests
Direct factor Xa inhibitors Edoxaban Rivaroxaban Apixaban 30mg,60mg 10 mg Starting with dose – followed by maintenance dosages Monitor for hepatic and renal diseases potassium and magnesium levels possible bleeding risks. Anti-thrombin inhibitor Dabigatran <75yo >75 yo 150mg 110mg Testing not necessary Checking kidney function recommended every year


  • They have easy doses
  • Their blood thinning ability usually reaches peak within hours after ingestion
  • Fixed daily doses eliminate need of constant monitoring unlike heparin/warfarin


  • Some medications do require twice-daily doses (cough cough Pradaxa)
  • Again – like every drug.. always check in with your doctor to see which option is right for you.

Aspirin: For those who want a less expensive solution

In some cases involving stroke prevention or cardiac events low dose aspirin can be indicated as an alternative therapy against developing severe clots.

How does it work?
It lowers both the potential clot-forming substances1 & production of platelet aggregation factors that are essential contributors to formation of unwanted clots.

And… The best part about this medication is its cost-effectiveness! I mean we’re talking pennies here people!

But, ultimately — aspirin just decreases chances rather than completely preventing clots from forming— so any consideration needs medical evaluation prior prescribing; Also beware of too much consumption detrimental effect on stomach lining / gastrointestinal tract issues such as Peptic Ulcers in susceptible individuals).

Deciding Which Medication Is Right For You

Okay, folks – now it’s time to get serious. When making decisions around anticoagulation medications, it’s crucial that you involve your doctor as they will help prescribe and monitor any medication adjustments.

Your doctor may take into consideration the following conditions:

  • Genetic mutations of clot-forming factors (e.g., Factor V Leiden mutation)
  • History of frequent clots
  • Underlying medical conditions (e.g., cancer or heart disease)

Trying to figure out what specific medication is right for you can be taxing.. Don’t beat yourself up over it (that would just cause more internal bleeding… wouldn’t it? Jk). But seriously — every individual comes with their unique set of requirements in terms of blood thinning therapy options.

Remember – do not self-diagnose; Do not abruptly stop taking anticoagulant treatment unless advised by physicians regarding risks posed..


That, my friends, is a rundown on the most commonly used blood thinners available today. You now possess some serious knowledge about Heparin, Warfarin & NOACs – including all their pros and cons!.

Ultimately—talk to your physician if any signs or symptoms develop such as shortness of breath/sudden onset severe chest pain/sharp leg swelling/.red warm skin over red hot inflamed surface areas.

Cheers to keeping those pesky little platelets from forming unwanted clots!


(There are none…but doesn’t this subsection seem appropriate after the above paragraph?)
