Skin rash may happen in people taking levofloxacin, even after only 1 dose. Stop taking levofloxacin at the first sign of a skin rash and call your healthcare provider. Skin rash may be a sign of a more serious reaction to levofloxacin.

Liver damage (hepatotoxicity) can happen in people who take levofloxacin. Call your doctor right away if you have unexplained symptoms such as:

  •  
nausea or vomiting
  •  
stomach pain

light colored bowel movements
  •  
dark colored urine or yellowing of your skin or the whites of your eyes

Seizures have been reported in people who take fluoroquinolone antibiotics including levofloxacin. Tell your doctor if you have a history of seizures. Ask your doctor whether taking levofloxacin will change your risk of having a seizure. Central Nervous System (CNS) side effects may happen as soon as after taking the first dose of levofloxacin. Talk to your doctor right away if you get any of these side effects, or other changes in mood or behavior:

Intestine infection (Pseudomembranous colitis)Pseudomembranous colitis can happen with most antibiotics, including levofloxacin. Call your doctor right away if you get watery diarrhea, diarrhea that does not go away, or bloody stools. You may have stomach cramps and a fever. Pseudomembranous colitis can happen 2 or more months after you have finished your antibiotic.

Changes in sensation and possible nerve damage (Peripheral Neuropathy)Damage to the nerves in arms, hands, legs, or feet can happen in people taking fluoroquinolones, including levofloxacin.

Serious heart rhythm changes (QT prolongation and torsades de pointes)
Tell your doctor right away if you have a change in your heart beat (a fast or irregular heartbeat), or if you faint. Levofloxacin may cause a rare heart problem known as prolongation of the QT interval. This condition can cause an abnormal heartbeat and can be very dangerous. The chances of this happening are higher in people:

  •  
who are elderly
  •  
with a family history of prolonged QT interval
  •  
with low blood potassium (hypokalemia)
  •  
who take certain medicines to control heart rhythm (antiarrhythmics)

Increased chance of problems with joints and tissues around joints in children can happen. Tell your child's healthcare provider if your child has any joint problems during or after treatment with levofloxacin.

Changes in blood sugar can occur. People who take levofloxacin and other fluoroquinolone medicines with oral anti-diabetes medicines or with insulin can get low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia). Follow your healthcare provider's instructions for how often to check your blood sugar. If you have diabetes and you get low blood sugar while taking levofloxacin, stop taking levofloxacin and call your healthcare provider right away. Your antibiotic medicine may need to be changed.

Sensitivity to sunlight (photosensitivity)

The most common side effects of levofloxacin include:

  •

Iquix Interactions

Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, herbal and dietary supplements. Levofloxacin and other medicines can affect each other causing side effects. Especially tell your doctor if you take:

  • an NSAID (Non-Steroidal Anti-Inflammatory Drug). Many common medicines for pain relief are NSAIDs. Taking an NSAID while you take levofloxacin or other fluoroquinolones may increase your risk of central nervous system effects and seizures. 
  • an oral anti-diabetes medicine or insulin
  • a blood thinner (warfarin, Coumadin, Jantoven)
  • a medicine to control your heart rate or rhythm (antiarrhythmics). 
  • an anti-psychotic medicine
  • a tricyclic antidepressant
  • a water pill (diuretic)
  • a steroid medicine. Corticosteroids taken by mouth or by injection may increase the chance of tendon injury. 
  • theophylline (Theo-24, Elixophyllin, Theochron, Uniphyl, Theolair)

Certain medicines may keep levofloxacin from working correctly. Take levofloxacin tablets or oral solution either 2 hours before or 2 hours after taking these products: an antacid, multivitamin, or other product that has magnesium, aluminum, iron, or zinc, sucralfate (Carafate), didanosine (Videx,Videx EC).

Iquix Precautions

Levofloxacin, a fluoroquinolone antibiotic, can cause serious side effects. Some of these serious side effects could result in death.

If you have any of the following serious side effects while you take levofloxacin, get medical help right away. Talk with your healthcare provider about whether you should continue to take levofloxacin.

1.  Tendon rupture or swelling of the tendon (tendinitis).
  • Tendon problems can happen in people of all ages who take levofloxacin. Tendons are tough cords of tissue that connect muscles to bones.
    Some tendon problems include pain, swelling, tears, and inflammation of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites.
  • The risk of getting tendon problems while you take levofloxacin is higher if you:
    • are over 60 years of age
    • are taking steroids (corticosteroids)
    • have had a kidney
    • heart or lung transplant
  • Tendon problems can happen in people who do not have the above risk factors when they take levofloxacin.
  • Other reasons that can increase your risk of tendon problems can include:
    • physical activity or exercise
    • kidney failure
    • tendon problems in the past, such as in people with rheumatoid arthritis (RA)
  • Call your healthcare provider right away at the first sign of tendon pain, swelling or inflammation. Stop taking levofloxacin until tendinitis or tendon rupture has been ruled out by your healthcare provider. Avoid exercise and using the affected area.
    The most common area of pain and swelling is the Achilles tendon at the back of your ankle. This can also happen with other tendons. Talk to your healthcare provider about the risk of tendon rupture with continued use of levofloxacin. You may need a different antibiotic that is not a fluoroquinolone to treat your infection.
  • Tendon rupture can happen while you are taking or after you have finished taking levofloxacin. Tendon ruptures have happened up to several months after people have finished taking their fluoroquinolone.
  • Get medical help right away if you get any of the following signs or symptoms of a tendon rupture:
    • hear or feel a snap or pop in a tendon area
    • bruising right after an injury in a tendon area
    • unable to move the affected area or bear weight
2.  Worsening of myasthenia gravis (a problem that causes muscle weakness). Fluoroquinolones like levofloxacin may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.

Do not take levofloxacin if you have ever had a severe allergic reaction to an antibiotic known as a fluoroquinolone, or if you are allergic to any of the ingredients in levofloxacin. Ask your doctor if you are not sure. 

Levofloxacin can make you feel dizzy and lightheaded. Do not drive, operate machinery, or do other activities that require mental alertness or coordination until you know how levofloxacin affects you.

Avoid sunlamps, tanning beds, and try to limit your time in the sun. Levofloxacin can make your skin sensitive to the sun (photosensitivity) and the light from sunlamps and tanning beds. You could get severe sunburn, blisters or swelling of your skin. If you get any of these symptoms while taking levofloxacin, call your doctor right away. You should use a sunscreen and wear a hat and clothes that cover your skin if you have to be in sunlight.

Iquix Usage

  • Take levofloxacin exactly as prescribed by your doctor.
  • Take levofloxacin at about the same time each day.
  • Drink plenty of fluids while taking levofloxacin.
  • Levofloxacin tablets can be taken with or without food.
  • Take levofloxacin oral solution 1 hour before or 2 hours after eating.
  • If you miss a dose of levofloxacin, take it as soon as you remember. Do not take more than one dose in one day.
