Clarithromycin acts by inhibiting microsomal protein synthesis in susceptible organisms mainly by binding to the donor site on the 50S subunit of the bacterial ribosome and preventing translocation to that site.

Remac is generally well tolerated. Side effects include nausea, vomiting, diarrhoea and abdominal pain. Stomatitis and glossitis have also been reported. Other side effects include headache, allergic reactions ranging from urticaria and mild skin reactions to anaphylaxis. Taste perversion may occur. There have been reports of transient central nervous system side effects including anxiety, dizziness, insomnia and hallucination.
The drug may be used in neonates and children in appropriate doses. Breast milk from mothers receiving Clarithromycin should not be given to infants until treatment is completed. There is as yet little experience in the treatment of pregnant patients and Clarithromycin is not recommended.
Remac should be discontinued if severe acute hypersensitivity reactions occur. Remac should be avoided in patients with known QT prolongation or receiving drugs known to prolong the QT interval, ventricular arrhythmia, hypokalemia or hypomagnesemia, significant bradycardia or taking Class IA or III antiarrhythmics.
