Advise patients that diarrhea is a common problem caused by antibacterials including Clarithromycin which usually ends when the antibacterial is discontinued.

If this occurs, instruct patients to contact their healthcare provider as soon as possible.

Zadok D, Levy Y, Glovinsky Y, et al. The effect of anthocyanosides on night vision abstract. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Clarithromycin and other antibacterial drugs, Clarithromycin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Be sure to use clarithromycin for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future. Meunier B, de Visser SP, Shaik S September 2004. "Mechanism of oxidation reactions catalyzed by cytochrome p450 enzymes".

Your doctor will order blood tests to monitor for this. Keep all medical appointments. With conventional tablets, food causes a slight delay in onset of clarithromycin absorption but extent of absorption is unaffected. 1 56 With extended-release tablets, food increases the extent of absorption by 30%. Compared to prior experience with clarithromycin monotherapy, the two-drug regimen of clarithromycin and ethambutol extended the time to microbiologic relapse, largely through suppressing the emergence of clarithromycin resistant strains. However, the addition of clofazimine to the regimen added no additional microbiologic or clinical benefit. Tolerability of both multidrug regimens was comparable with the most common adverse events being gastrointestinal in nature. Patients receiving the clofazimine-containing regimen had reduced survival rates; however, their baseline mycobacterial colony counts were higher. The results of this trial support the addition of ethambutol to clarithromycin for the treatment of initial dMAC infections but do not support adding clofazimine as a third agent.
