Description

Increased risk of ECG abnormalities with quinine or chloroquine, antihistamines, TCAs and phenothiazines. May increase risk of seizure with quinidine or quinine. Concomitant use with valproic acid, phenobarbital, carbamazepine and phenytoin may cause loss of seizure control and lower plasma levels of anticonvulsants. Increased risk of QT prolongation and arrhythmia with ketoconazole. Concomitant use with digoxin, Ca channel blockers, antiarrhythmics and β-blockers may increase the risk of cardiotoxicity. Increased risk of ventricular arrhythmias with amiodarone. Concomitant use with TCAs, SSRIs, buprion, antipsychotic, tramadol may increase the risk of convulsions. Increased plasma levels with metoclopromide. May compromise adequate immunisation by live typhoid vaccine. Vaccinations with attenuated live bacteria should be completed at least 3 days prior the 1st dose of mefloquine.

Among subjects who received Mefloquine for prophylaxis of malaria, following side effects was observed: The most frequently observed sied-effects were vomiting, dizziness, syncope, extrasystoles and other complaints affecting less than 1%.

Mefloquine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Use in Nursing Mothers: Mefloquine is excreted in breast milk in small amounts. the activity of which is unknown.

Rare cases of suicidal ideation and suicide have been reported though no relationship to drug administration has been confirmed. Mefloquine should be used with caution in patients with a previous history of depression. Concomitant administration of Mefloquine and quinine or quinidine may produce electrocardiographic abnormalities and may increase risk of convulsions. Precautions: In patients with epilepsy, Mefloquine may increase the risk of convulsions. Caution should be exercised with regard to activities requiring alertness and fine motor coordination such as driving, piloting aircraft and operating machinery. Mefloquine should be used with caution in patients with psychiatric disturbances. In patients with impaired liver function the elimination of Mefloquine may be prolonged, leading to higher plasma levels.

In cases of overdosage with Mefloquine, the symptoms may be more pronounced. The following procedure is recommended in case of overdosage: Induce vomiting or perform gastric lavage, as appropriate. Monitor cardiac function (if possible by ECG), neurologic and psychiatric status for at least 24 hours. Provide Symptomatic and intensive supportive treatment as required, particularly of cardiovascular disturbance. Treat vomiting or diarrhoea with standard fluid therapy.
