Cipro is an antibiotic that is linked to rare but severe side effects, including heart failure, heart attacks, aortic aneurysms, nerve damage, and severe skin reactions.
Cipro and Heart Problems
Cipro is known to damage collagen and other connective tissues throughout the body, including the tendons, heart, and aorta. In September 2019, a study found an increased risk of heart valve damage from Cipro and other fluoroquinolone antibiotics. When the heart valves do not work properly, it can lead to heart failure and other life-threatening cardiovascular side effects.
Cipro and Aortic Aneurysms
In December 2018, the FDA warned about an increased risk of aortic aneurysms from Cipro and other fluoroquinolone antibiotics. This rare but serious side effect occurs when the aorta (the largest blood vessel in the body) suddenly rips open and causes massive internal bleeding or even death.
Cipro and Stevens-Johnson Syndrome (SJS)
Cipro is linked to rare a rare but severe skin reaction called Stevens-Johnson Syndrome (SJS) or Toxic Epidermal Necrolysis. These side effects may occur after just one dose of Cipro. The rash spreads all over the body and the top layer of skin dies and peels off, which can result in blindness, sepsis, and death.
Cipro and Nerve Damage
In August 2013, the FDA warned that Cipro and other fluoroquinolone antibiotics increase the risk of peripheral neuropathy, a serious type of nerve damage in the arms and legs. The symptoms can appear within days of taking the first dose of Cipro and cause long-lasting pain, numbness, tingling, and other symptoms.
