Prednisone and Achilles Tendon Rupture

Direct Answer

• Yes, corticosteroids such as prednisone can cause or significantly increase the risk of tendon rupture, including the Achilles tendon.

Mechanism and Risk Factors

• Collagen Breakdown: Prednisone and related drugs interfere with collagen synthesis and normal tendon metabolism, leading to weakened tendon integrity.
• Onset of Injury: Ruptures can occur even after short-term use, though the risk generally increases with higher cumulative doses and prolonged therapy.
• Contributing Triggers: The risk is further compounded by factors such as concurrent use of certain antibiotics (like fluoroquinolones), physical exertion, age, and pre-existing local inflammation or degeneration.

Recommendations

• Immediate Medical Evaluation: Any sudden pain, swelling, popping sensation, or loss of strength in the back of the ankle requires prompt medical attention.
• Caution with Activity: Avoid strenuous weight-bearing exercise or stretching if tendon discomfort arises during or after corticosteroid treatment.
