How Long Does It Take For Levaquin To Leave The Body?

Levaquin can leave the body in a couple of days, but some adverse reactions can happen months later.

If the patient generally has good health, the body can eliminate Levaquin (levofloxacin) in about 30 to 40 hours, or about a day and a half to two days, but some side effects of the drug can show up as long as two months or longer after taking the medicine. Some of the adverse reactions are irreversible.

Levaquin is a type of fluoroquinolone antibiotics. These medications have been in use, in one form or another, for over 30 years. Doctors used to prescribe these antibiotics frequently to treat skin infections, bronchitis, and infections of the sinus or urinary tract. The U.S. Food and Drug Administration (FDA) issued warnings and restrictions about the use of Levaquin and other fluoroquinolones because of dangerous side effects.

Significant Side Effects of Levaquin

Because of the potential harm this drug can cause, the FDA warns that doctors should only prescribe it when there is no viable alternative to treat the person’s illness. Children under the age of 18 should only take Levaquin if they have the plague or have exposure to anthrax or the plague.

• Ruptures or tears in the aorta, the main artery of the body. Aortic dissection and aortic aneurysm are other terms for this condition. These conditions can cause hemorrhage or death.
• Swelling of tendons (tendinitis) or rupture of tendons can happen when taking Levaquin or as long as several months after taking the antibiotic
• Nerve damage and changes in sensation can happen soon after you start taking Levaquin. The nerve damage is sometimes permanent.
• Levaquin can harm your brain or nervous system. This adverse reaction can happen with only one dose of the antibiotic.
• Levaquin is particularly dangerous for people with myasthenia gravis, which is a nervous system disorder. The antibiotic can worsen the muscle weakness of myasthenia gravis to the extent that a person can struggle to breathe or can die.
