Yes, it's true. In some cases, antibiotics called fluoroquinolones can cause the tendons to weaken, leading to damage, and in some cases, complete tendon rupture.
In the past, doctors did not hesitate to prescribe common fluoroquinolones such as Cipro and Levaquin to their patients for the treatment of sinus infections, urinary tract infections, kidney infections and much more. Recently, however, doctors have been more cautious about writing prescriptions for fluoroquinolones. This is due to the mounting evidence that suggests these antibiotics can cause serious tendon injury.
The FDA first warned the public about these dangers in 2008, and have continued to make drug safety announcements on their website as recently as July 2016. These warnings from the FDA have gotten more and more serious over the years. In 2008, the FDA announced the requirement for all fluoroquinolones to be labeled with a "black box" warning on the outside regarding potential tendon damage. In 2013, the FDA's announcement about fluoroquinolones included a warning about potential nerve damage from usage of the antibiotics. In May of 2016, the FDA's warning stated that fluoroquinolones should only be used as a last ditch effort if other drugs have failed and there are no other options.
The tendon most likely to be damaged by taking fluoroquinolones is the Achilles Tendon (located at the back of your ankle), but the other tendons in your body are also at risk.
Anyone who has taken fluoroquinolones within the past several years is potentially at risk. You aren't just at risk while you're actively taking the drugs -- tendon injury associated with the use of fluoroquinolones can show up several weeks, months, or even years after you stopped taking the drugs. The longer you took the antibiotics and the higher your dosage, the more likely you are to experience tendon damage.
There are also certain outside factors that increase your chances of tendon damage. For one, if you are over the age of 40, your risk increases because our tendons naturally grow weaker as we age. Another risk factor is using corticosteroids, as they can also contribute to the weakening of tendons. If you've used fluoroquinolones and have a history of taking corticosteroids for something like arthritis or asthma, you are at greater risk of developing a tendon injury.
Being physically active is probably the biggest risk factor. When you're active, you have a much greater chance of injuring a tendon than someone who doesn't lead an active lifestyle. Your risk of tendon damage increases further if you've injured a tendon in the past.
Tendon damage ranges from mild, to moderate, to severe. Tendon injuries are usually described as "Grades" that include Grade 1 (mild strain), Grade 2 (moderate tear), and Grade 3 (full tear).
A Grade 1 tendon injury is a mild strain of the tissue that can cause pain and swelling, but shouldn't affect movement of the joint.
A Grade 2 tendon injury is a partial tear of the tissue, which means the tissue has been torn but is still holding together. Signs and symptoms may include pain, inflammation and reduced range of motion.
A Grade 3 tendon injury is a complete tear, also called a rupture. This means your tissue is in two separate pieces. You will likely experience severe pain, inflammation, possible bruising and reduced range of motion, or inability to bear weight on the joint (depending on the location of the damaged tendon).
Grade 3 tendon tears are very serious and usually require surgery to repair.
It doesn't matter how severe your tendon damage is -- tendon injuries can take weeks or even months to heal, putting your life on hold and even causing permanent damage.

Start with the ColdCure® Wrap to relieve the pain and reduce any swelling and inflammation. Use the ColdCure® Wrap in cycles of 20 minutes on and 20 minutes off for as long as is needed. Continue doing ColdCure® treatments until any external swelling is gone and the pain has been reduced.
You can start using the BFST® Wrap once the visible swelling is gone. You may want to start with treatments that are only 5-10 minutes in length to see how your body reacts. If you still have a lot of internal inflammation, treatments may be quite hot, which means you should go back to using the ColdCure® Wrap. If your body responds well to the
5-10 minute BFST® treatments, you can start doing treatments for the full 20 minutes. Try doing 3-4 full 20 minute BFST® treatments every day, as this will work to promote blood flow and improve your circulation, helping to heal your tendon damage.
