Epilepsy, history of CNS disorders; severe renal or hepatic dysfunction; G6PD deficiency; maintain adequate hydration; myasthaenia gravis. Caution when used in patients with QT prolongation or risk factors e.g. bradycardia, pre-existing cardiac disease or uncorrected electrolyte disturbances. Discontinue treatment if patients experience tendon pain, inflammation or rupture. Avoid usage in methicillin-resistant staphylococcus aureus (MRSA) infections due to high level of resistance. May impair ability to drive or operate machinery. Safety and efficacy have not been established in pregnant and lactating women. Not to be used in children <18 yr; except where benefit clearly exceeds risk.
Lactation: Drug enters breast milk; use not recommended (American Academy of Pediatrics Committee states that drug is compatible with nursing)
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
Mode of Action
Ciprofloxacin promotes breakage of double-stranded DNA in susceptible organisms and inhibits DNA gyrase, which is essential in reproduction of bacterial DNA.
Interaction
May increase plasma concentrations of CYP1A2 substrates (e.g. clozapine, ropinirole, theophylline). Enhances effect of oral anticoagulants (e.g. warfarin) and glibenclamide. Increased toxicity of methotrexate. Plasma concentrations may be increased by probenecid.
Reduced absorption w/ oral multivitamins and mineral supplements containing divalent or trivalent cations (e.g. Fe, Zn, Ca) and antacids containing Al, Ca or Mg. Concomitant use w/ class IA antiarrhythmics (e.g. quinidine, procainamide), class III antiarrhythmics (e.g. amiodarone, sotalol), TCAs, macrolides and antipsychotics may result in additive effects on QT interval prolongation. Concurrent use w/ corticosteroids may increase risk of severe tendon disorders. Increased risk of CNS stimulation w/ NSAIDs. Altered serum concentrations of phenytoin.
Potentially Fatal: Marked elevation in serum levels of tizanidine which is associated w/ potentiated hypotensive and sedative effect.
