Look for Drugs and Conditions



Gatifloxacin is a fluoroquinolone antibiotic used to treat various bacterial infections. It works by inhibiting bacterial DNA synthesis, thereby preventing the growth and multiplication of susceptible bacteria.


-Respiratory tract infections (e.g., pneumonia, bronchitis) -Skin and soft tissue infections -Urinary tract infections -Ophthalmic infections (as eye drops)


Dosage may vary depending on the specific condition being treated. Consult with a healthcare professional for accurate dosage information. Typically, oral tablets are taken with or without food, and eye drops are applied as directed.


Gatifloxacin is contraindicated in individuals with a history of hypersensitivity to fluoroquinolones or any of the components of the medication. It should be avoided in pregnant women, nursing mothers, and children unless the potential benefits outweigh the risks.

Special Precautions

Caution is advised in patients with a history of tendon disorders or myasthenia gravis. Gatifloxacin may increase the risk of tendinitis and tendon rupture, especially in older adults. Patients should be advised to avoid excessive sunlight exposure due to the potential for phototoxic reactions.

Side Effects

Common side effects may include nausea, diarrhea, headache, dizziness, and insomnia. Serious side effects such as tendonitis, peripheral neuropathy, and allergic reactions are rare but should be reported to a healthcare professional promptly.

Drug Interactions

-Concurrent use with non-steroidal anti-inflammatory drugs (NSAIDs) may increase the risk of CNS stimulation and seizures. -Gatifloxacin may enhance the effects of oral anticoagulants, leading to an increased risk of bleeding. -Use caution when combining with drugs known to prolong the QT interval, as gatifloxacin may also prolong this interval.
