Joint Pain, Swelling or Inflammation

If you experience pain, swelling or inflammation around your joints, stop taking Sandoz Levofloxacin immediately. Levofloxacin tablets have been linked to tendinitis and tendon rupture, which may require surgery. This may happen while you are taking Sandoz Levofloxacin or up to several months afterwards.

The risk of tendon effects is higher if you are over 60 years old, if you are taking corticosteroids, if you’ve had a kidney, heart or lung transplant, or if you have any joint related issues (rheumatoid arthritis).

Aortic Aneurism and Dissection

Quinolones, including levofloxacin tablets, have been associated with an enlargement or "bulge" of a large blood vessel (aortic aneurysm or large vessel peripheral aneurysm) and aortic dissection (a tear in the aorta wall). A tear in a blood vessel is more common if you are also taking corticosteroids. The risk of these problems is higher if you:

• are elderly
• have or anyone in your family has had aneurysm disease
• have an aortic aneurysm or an aortic dissection
• have heart valve regurgitation/incompetence
• have any of the following conditions: Marfan syndrome, vascular Ehlers-Danlos syndrome, Takayasu arteritis or giant cell arteritis or Behcet's disease, Turner syndrome, rheumatoid arthritis, Sjögren’s syndrome
• have high blood pressure or atherosclerosis
