Clarithromycin (Biaxin)

Clarithromycin is a prescription macrolide antibiotic. It is sold as Biaxin, Klacid and Klaricid by Abbott Laboratories. Clarithromycin is used to treat bacterial infection such as upper respiratory tract (pharyngitis, tonsillitis), acute sinusitis, lower respiratory tract (acute bacterial exacerbation of chronic bronchitis, pneumonia), and skin infections. It is used in combination with other medications to eliminate H. pylori, a bacteria that causes peptic ulcers.

Clarithromycin offers a convenient dosing regimen - twice daily. It is very effective against a wide range of bacteria. It is more effective against the most common cause of a bacterial pneumonia (Streptococcus pyogene and Streptococcus pneumoniae), than erythromycin.

It is well tolerated by children and has a low rate of side effects. Most side effects are mild to moderate, mostly gastrointestinal.

Drug Information

Clarithromycin is a semisynthetic derivative of erithromycin. It was discovered by researchers at the Japanese company Taisho Pharmaceutical in the 1970s. Taisho granted a licence to Abbott for the development of the drug worldwide, except in Japan, Korea and Taiwan.

Clarithromycin works by preventing bacteria from producing essential proteins. It doesn’t directly kill the bacteria, but leaves them unable to grow and multiply.

How to take

  • Classified as pregnancy category C, because negative fetal effects have been documented in animal studies.
  • Do NOT use Clarithromycin or Biaxin if you are taking cisapride, cyclosporine, dofetilide, eletriptan, ergot alkaloid (eg, dihydroergotamine, ergotamine), H1 antagonist (eg, astemizole, terfenadine), pimozide, or QT-prolonging agent (eg, quinidine, sotalol, thioridazine). Their concomitant use is contraindicated because of potentially serious cardiotoxicity.
  • Clarithromycin may be used without regard to food.
  • It works best if taken at the same time each day.
  • Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it.

Clarithromycin (Biaxin) dosage:

Respiratory, ear, and skin infections:
Your doctor will carefully tailor your individual dosage for Clarithromycin depending upon the type of infection and organism causing it. The usual dose varies from 250 to 500 mg every 12 hours for 7 to 14 days.

Clarithromycin is not recommended for children under 6 months of age. The dose for children older than 6 months depends on how much the child weighs. It is usually given twice a day for 10 days.

Remember about the importance of completing the full course of prescription, even if feeling better after a few days. Not completing therapy may increase the likelihood that bacteria will develop resistance and will not be treatable with clarithromycin in the future.
