Warning & Precautions

"Exacerbation of myasthenia gravis:Fluoroquinolones have neuromuscular blocking activity and may exacerbate muscle weakness in persons with myasthenia gravis. Postmarketing serious adverse events, including deaths and requirement for ventilator support, have been associated with fluoroquinolone use in persons with myasthenia gravis. Avoid fluoroquinolones in patients with known history of myasthenia gravis. -Patients predisposed to seizures should use levoflox with extreme caution.

 - If pseudo-membraneous colitis is suspected, levoflox must be stopped immediately. - tendinitis: rarely observed with quinolones, may occasionally lead to rupture involving Achilles tendon in particular. This undesirable effect may occur within 48 hours of starting of treatment and may be bilateral Elderly patients are more prone to tendinitis.

 -The risk of tendon rupture may be increased by the co-administeration of corticosteroid, if tendinitis is suspected, treatment with levoflox must be stopped immediately and the affected tendons must be put at rest. - The dose of levoflox should be adjusted in patients with renal impairment.

 - It is recommended that patients should not expose themselves unnecessarily to strong sunlight or to artificial UV or to artificial UV rays. 

- Patients with latent or actual defects in glucose-6-phosphate dehydrogenase activity may be prone to hemolytic reactions when treated with quinolone antibacterial agents (e.g.levoflox).

 - Levoflox may cause dizziness, vertigo and visual disturbances which may cause risk during driving a car or operating machinery. - The use of levofloxacin, especially if prolonged, may result in overgrowth of non-susceptible organisms.

- No dose adjustment is required in patients with impaired liver function, elderly patients. However, special attention to renal function should be paid in elderly patients, and the dosage should be adapted accordingly.

- Levoflox is only intended for slow intravenous infusion administered once or twice daily. The infusion time must be at least 30 minutes for 250 mg or 60 minutes for 500 mg.

Levoflox is contraindicated during pregnancy and lactation.

Drug Interactions

"It is recommended that preparations containing divalent or trivalent cations such as iron salts or magnesium or aluminium containing antacids should not be taken 2 hours before or after levoflox administration because of a possible reduction in absorption.

- The bioavailability of levofloxacin is significantly reduced when administered together with sucralfate, so it is recommended to administer sucralfate 2 hours after the the levoflox administration.

- Pronounced lowering of the cerebral seizure threshold may occur when quinolones (e.g. levoflox) are given concurrently with theophylline, fenbufen or similar non steroidal anti-inflammatory drugs or other agents, which lower the seizure threshold.

- Caution should be exercised when levoflox is co-administered with drugs that affect the tubular renal secretion such as probenecid and Cimetidine, especially in renally impaired patients.

- Increased coagulation tests and/or bleeding, which may be severe, are reported in patients treated with levoflox in combination with a vitamin K antagonist (e.g warfarin).

- Levoflox solution for infusion should not be mixed with heparin or alkaline solutions (e.g. sodium hydrogen carbonate) but is compatible with the following solutions for infusion: 0.9% sodium chloride solution, 5 % dextrose injection, 2.5% dextrose in ringer solution or combination solutions for parenteral nutrition (amino-acids, carbohydrates electrolytes) .
