    Before taking Biaxin Filmtab

    In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of clarithromycin to treat bacterial infections in children younger than 6 months of age, and to prevent and treat Mycobacterium avium complex in children younger than 20 months of age. Safety and efficacy have not been established in these age groups.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of clarithromycin in the elderly. However, elderly patients are more likely to have severe kidney problems and heart rhythm problems, which may require caution and an adjustment in the dose for patients receiving clarithromycin.

    Breast Feeding

    There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
