Blood thinners are drugs that are used to treat and prevent blood clots. They reduce the clotting ability of the blood, which makes it harder to stop bleeding in case of a cut or injury. Some common blood thinners include Eliquis, Xarelto, Warfarin, Heparin, and Rivaroxaban. While these drugs are effective in preventing blood clots, they can also cause various side effects, such as bleeding, stomach pain, itchy skin, and bruising. One of the rare side effects of blood thinners is muscle spasms. In this article, we will explore the potential link between blood thinners and muscle spasms and provide information on other related side effects.

What You'll Learn
Eliquis (apixaban) and muscle spasms
Eliquis (apixaban) is a prescription medicine used to reduce the risk of stroke and blood clots in people who have atrial fibrillation (AFib), a type of irregular heartbeat. It is also used to treat blood clots in the veins of the legs (deep vein thrombosis) or lungs (pulmonary embolism). As a blood thinner, Eliquis can cause bleeding, which can be serious and rarely may lead to death. The most common adverse reactions are related to bleeding, including anemia, haemorrhage, and nausea. Other common side effects include arthralgia, back pain, pain in extremity, osteoarthritis, muscle spasms, musculoskeletal pain, myalgia, and arthritis.
Muscle spasms are a recognised side effect of Eliquis (apixaban). According to Drugs.com, muscle spasms are a common side effect, occurring in 1% to 10% of patients. If you are experiencing muscle spasms while taking Eliquis, it is important to consult your doctor or healthcare provider. They can help you manage your symptoms and discuss whether any adjustments to your medication are necessary.
It is worth noting that Eliquis (apixaban) can also increase the risk of blood clots in the spine or epidural area, which may lead to long-term or permanent paralysis. This risk is higher if you have an epidural catheter in your back, are taking blood clotting medicine, or have a history of spinal problems or surgery. Therefore, it is crucial to inform your doctor immediately if you experience any symptoms such as tingling, numbness, or muscle weakness, especially in your legs and feet.
While muscle spasms are a recognised side effect of Eliquis (apixaban), the exact mechanism by which it causes these spasms is not clearly understood. However, it is likely related to the drug's impact on blood clotting and circulation. Muscle spasms can result from various factors, including reduced blood flow or changes in the balance of electrolytes and fluids in the body. As Eliquis alters blood clotting and can affect circulation, it may indirectly contribute to muscle spasms in some individuals.
Additionally, it is important to be cautious when discontinuing Eliquis (apixaban) or any other blood thinner. Stopping the medication without medical advice can increase the risk of blood clots and stroke. Always consult your doctor before making any changes to your medication regimen. They will provide guidance on safely tapering off the drug and discuss alternative treatment options if needed.

Xarelto (rivaroxaban) and muscle spasms
Xarelto (rivaroxaban) is a prescription drug used to treat and prevent blood clots. It is also used to prevent stroke and blood clots in patients with certain heart rhythm problems, such as nonvalvular atrial fibrillation. The drug comes in tablet or liquid suspension form and is taken orally. As a blood thinner, Xarelto works by decreasing the clotting ability of the blood, thereby helping to prevent harmful clots from forming in the blood vessels.
Like all medications, Xarelto can cause side effects, some of which may be serious. The most common side effect of Xarelto is bleeding, which can range from mild to severe. Mild bleeding may include nose bleeds or light bruising, while severe bleeding may include bleeding that doesn't stop or blood in the stool or urine, which requires immediate medical attention. Other common side effects include stomach pain, itchy skin, fatigue, and back pain.
Xarelto may also cause muscle spasms, which are listed as a common side effect, occurring in 1% to 10% of patients. If you experience muscle spasms or any other side effects while taking Xarelto, it is important to consult your healthcare provider. Do not stop taking Xarelto without first checking with your doctor, as this may increase your risk of having a stroke or developing blood clots.
It is worth noting that the side effects of Xarelto are usually mild and temporary, and some may be easily managed. However, if you have any symptoms that are ongoing or bothersome, it is important to talk to your doctor or pharmacist. They can help you manage your symptoms and discuss ways to alleviate them.

Warfarin and muscle spasms
Warfarin is a prescription medicine used to prevent or treat blood clots, including deep venous thrombosis or pulmonary embolism. It is also used for blood clots caused by certain heart conditions, open-heart surgery, or after a heart attack. Warfarin is an anticoagulant, or blood thinner, that decreases the clotting ability of the blood.
While warfarin is effective in preventing and treating blood clots, it can also cause several side effects, including an increased risk of bleeding. This is a common side effect of blood thinners, and patients taking warfarin may bruise more easily and experience longer bleeding times. Warfarin can also increase the risk of bleeding during dental work or when using sharp objects like razors or nail cutters. It is recommended that patients taking warfarin carry identification stating their medication and avoid contact sports or activities where injury is likely.
In addition to bleeding risks, warfarin may also cause muscle twitching, as mentioned in a list of side effects to watch out for. While muscle twitching is a recognized side effect, there is limited information specifically linking warfarin to muscle spasms. However, in rare cases, warfarin has been associated with peripheral neuropathy, which can result in severe pain and varying degrees of motor and sensory impairment.
It is important to note that the occurrence of muscle spasms or twitching in individuals taking warfarin may be influenced by various factors, including the presence of other medical conditions or interactions with certain medications. Therefore, it is always advisable to consult a healthcare professional for personalized advice and to report any unusual symptoms.
Overall, while muscle spasms may not be a commonly recognized side effect of warfarin, it is crucial for individuals taking this medication to be aware of any unusual bodily responses and to maintain open communication with their healthcare providers.

Bleeding risk and muscle spasms
Blood thinners are used to prevent or treat blood clots, including deep venous thrombosis or pulmonary embolism. They are also used for blood clots that may be caused by certain heart conditions, open-heart surgery, or a heart attack. Blood thinners can be taken by mouth, given by IV, or by under-skin injection.
The most common side effect of blood thinners is bleeding, which can be serious and rarely may lead to death. Bleeding can be a sign of more severe conditions, such as a blood clot or a problem with the spine or epidural area, which may lead to long-term or permanent paralysis. Other signs of more severe conditions include back pain, tingling, numbness, or muscle weakness. If you experience any of these symptoms, contact your healthcare provider right away.
The risk of bleeding depends on the type of blood thinner used. Warfarin, for example, has a much higher risk of causing bleeding than other blood thinners because it requires a precise dosage. Heparin can cause a condition called thrombocytopenia, with two types: Type I HIT, which happens to about 10% of people on heparin, and Type 2 HIT, which triggers your immune response to activate platelets and can cause widespread clotting in your body. About 2% of patients on heparin experience major bleeding, while people on warfarin have a 0.4% to 7.2% risk of major bleeding and up to a 15% chance of minor bleeding. If you take one of the newer oral anticoagulants, the risk is less.
In addition to bleeding, other side effects of blood thinners include stomach pain, itchy skin, fatigue, and hair loss. Some people may also experience muscle spasms as a side effect of blood thinners, as is the case with Eliquis (apixaban), which is used to reduce the risk of stroke and blood clots in people with atrial fibrillation.

Other medication interactions and muscle spasms
Blood thinners such as Xarelto, Eliquis, and warfarin are known to cause bleeding, which is usually mild and may present as light bruising or nose bleeds. However, there is no mention of muscle spasms as a side effect of these blood thinners.
Several medications have been linked to muscle spasms and other related issues such as muscle pain, weakness, stiffness, and cramps. These include:
- Cholesterol-lowering drugs such as statins (e.g., simvastatin, atorvastatin) and fibrates (e.g., fenofibrate, gemfibrozil). Fibrates, in particular, can cause muscle-related problems that can lead to rhabdomyolysis, which is more likely in older adults and those with diabetes, kidney problems, or hypothyroidism.
- Antiarrhythmic medicines used to treat heart rhythm problems, such as amiodarone and procainamide.
- Corticosteroids, especially at high doses and for prolonged periods, such as prednisone. This can lead to steroid-induced myopathy, which typically affects pelvic muscles and results in muscle weakness without pain.
- Antiepileptic drugs such as lamotrigine and phenytoin.
- Pregabalin (Lyrica), which treats certain types of seizures and nerve pain, can cause muscle pain and spasms.
- Isotretinoin (commonly used to treat severe acne) can cause muscle and joint pain.
- Tumor necrosis factor-alpha inhibitors, such as etanercept and adalimumab.
- D-penicillamine, a chelating agent used to treat Wilson's disease.
- Omeprazole, a medication for gastroesophageal reflux disease (GERD).
It is important to note that not everyone who takes the aforementioned medications will develop muscle spasms or myopathy (muscle disease). However, if you experience any muscle-related issues while taking these or other medications, consult your healthcare provider. They may recommend adjusting the dosage, switching medications, or managing symptoms through methods such as hot or cold compresses or over-the-counter pain relievers.
