Medications induced risk of tendon rupture
Some medications, particularly certain antibiotics and cholesterol-lowering drugs, have been linked to an increased risk of tendon rupture. Here’s how they can affect your tendons:
Fluoroquinolone Antibiotics :Medications that increase risk of tendon rupture
- Fluoroquinolones are often prescribed for infections like bronchitis, sinusitis, and urinary tract infections.
- According to the study in BottomLine published in 2018 , reported Fluoroquinolones, such as ciprofloxacin (Cipro), levofloxacin, and moxifloxacin, can interfere with collagen-regulating components in tendons.
- This interference can weaken the tendons, making them more susceptible to tears and ruptures.
- According to the study published on Drug-induced tendinopathy in 2024 ,Fluoroquinolone antibiotics can cause tendinopathy at any dose, through any administration route, and at any time.
- This tendon problem usually appears suddenly, sometimes within 48 hours of starting the medication, but it can also develop months after the medication is stopped.
- Fluoroquinolone-associated tendinopathy can last a long time, be disabling, and may not be reversible.
- If a patient experiences any signs of tendonitis (like pain, swelling, or inflammation), the fluoroquinolone should be stopped immediately, and a different antibiotic should be used. Patients should rest the affected area and avoid strenuous activity.
- According to the study published in US.Pharmacist 2021 ,Levofloxacin significantly increased the risk of tendon rupture.
Statins: Medications that increase risk of tendon rupture
- According to the study reported in Toxicology Pathology in 2017 Cholesterol-lowering drugs, including atorvastatin (Lipitor), simvastatin (Zocor), and rosuvastatin (Crestor), can block the formation of coenzyme Q10 (CoQ10).
- CoQ10 is essential for synthesizing ATP, the energy currency of cells
- By interfering with ATP production, statins can weaken tendons and increase the risk of tendon injuries.
- According to the article published in Medsafe in 2024 ,Statin-induced tendinopathy can develop at any dosage and typically manifests around 8 to 10 months after beginning the medication. If tendinopathy is suspected, it is advisable to discontinue statin use. Be aware that if statin treatment is resumed, tendinopathy may recur.
Corticosteroids:Medications that increase risk of tendon rupture
- Medications like prednisone and methylprednisolone, used to treat inflammation and autoimmune conditions, can also weaken tendons over time.
- According to the study on Drug induced tendon injury in 2018,Prolonged use of corticosteroids can lead to tendon degeneration and increase the risk of rupture.
Aromatase inhibitors: Medications that increase risk of tendon rupture
- According to the Health Canada Summary Safety Review in 2023 , Aromatase inhibitors (like anastrozole, letrozole, and exemestane) have linked these drugs to tendonitis and even tendon rupture. .
- According to the study reported in Toxicology Pathology in 2017 , Aromatase inhibitors have been associated with tenosynovitis, especially in the hands and wrists.
- According to the study reported in Joint Bone Spine in 2014 , side effect can appear anywhere from two weeks to nineteen months after starting the medication.
- Additionally, more recent reports have linked these drugs to tendonitis and even tendon rupture.
While less consistently documented, tendinopathy has also been reported with other medications, including :
- anabolic steroids
- isotretinoin
- antiretroviral drugs (particularly protease inhibitors)
Risk Factors for Drug-Induced Tendon Ruptures
While not everyone taking these medications will suffer from tendon injuries, several factors can heighten the risk.
Age and Gender: Research from the International Journal of Molecular Sciences (2023) indicates that older adults, particularly those over 60, are more susceptible to tendon problems. Additionally, men appear to have a higher likelihood of experiencing tendon ruptures when on certain medications.
Pre-Existing Conditions: According to a study published in Diabetes Care (2024), certain health conditions such as diabetes, kidney disorders, and rheumatoid arthritis can significantly increase the risk of tendon damage.
Physical Activity and Lifestyle: A study in Sports Medicine Research and Practice suggests that both highly active and sedentary lifestyles can elevate the risk. High-impact sports or intense physical activity can strain tendons further, particularly if they’re already weakened by medication. Conversely, prolonged periods of inactivity can reduce tendon flexibility, making them more prone to injury.
Conclusion:Medications that increase risk of tendon rupture
Medications such as fluoroquinolone antibiotics, statins, corticosteroids, and aromatase inhibitors have been strongly linked to an increased risk of tendon rupture and tendinopathy. These drugs can weaken tendons by disrupting collagen synthesis, reducing energy production in tendon cells, or causing inflammation and degeneration. For example, fluoroquinolones like Ciprofloxacin and Levofloxacin can lead to sudden and sometimes irreversible tendon damage, even after short-term use. Similarly, statins like Atorvastatin and Simvastatin may impair tendon health by blocking CoQ10 production, while corticosteroids and aromatase inhibitors can cause long-term tendon degeneration.
Risk factors such as age, pre-existing conditions (e.g., diabetes or kidney disease), and lifestyle choices (e.g., high-impact sports or prolonged inactivity) further increase susceptibility to medication-induced tendon injuries. Early recognition of symptoms like pain, swelling, or stiffness is crucial, as prompt discontinuation of the offending medication and appropriate management can prevent severe outcomes like tendon rupture.
Patients and healthcare providers must remain vigilant about the potential risks associated with these medications. Safer alternatives should be considered where possible, and any signs of tendon damage should be addressed immediately. Reporting adverse effects to regulatory agencies also plays a vital role in improving drug safety and protecting future patients. By understanding these risks and taking proactive measures, individuals can better safeguard their tendon health while managing their medical conditions.

FAQs: Medications that increase risk of tendon rupture
What is a tendon rupture?
A tendon rupture is a tear or break in a tendon, often caused by overuse, injury, or certain medications.
What medications can increase the risk of tendon rupture?
Certain medications can increase the risk of tendon rupture, particularly in the Achilles tendon. The most common culprits include:
Fluoroquinolones: This class of antibiotics, which includes ciprofloxacin (Cipro), levofloxacin (Levaquin), and moxifloxacin (Avelox), is associated with an increased risk of tendon rupture, especially in older adults and those taking corticosteroids.
Corticosteroids: Long-term use of corticosteroids, such as prednisone, can weaken tendons and increase the risk of rupture.
Statins: These cholesterol-lowering medications have been linked to an increased risk of tendon rupture, although the risk is relatively low.
Aromatase inhibitors: These medications, used to treat breast cancer, can also increase the risk of tendon rupture.
