Upsides
  • Available as a generic in the tablet and suspension form.
  • The suspension can be used if you have problems swallowing.
  • Used to treat many types of bacterial infections.
  • Bacteria is less resistant to this antibiotic, meaning that Zithromax (azithromycin) will fight off the bacteria better. Your doctor may run tests to see which antibiotics will kill the bacteria causing your infection.
  • Immediate release form can be taken with or without food.
  • Available in generic.
  • Comes in different formulations (gel, solution, lotion, foam) to fit your preferences.
  • Works well for the kind of acne that causes large, red, and swollen pimples.
Downsides
  • Must space out antacids by at least 2 hours.
  • Use with caution if you have liver disease.
  • Must be used with caution if you are on medications to thin the blood (anticoagulants) because of increased risk of bleeding.
  • Foam formulation can cause headaches.
  • You will likely have to use another acne medicine along with Cleocin (clindamycin) since it is not as effective by itself.
  • Is only preferred for mild to moderate acne. If you have severe acne your doctor will most likely prescribe an oral medication.
  • If you only have comedonal acne (small skin-colored bumps on the skin) without any red, swollen pimples, your doctor may give you an alternative medicine.
