Topical treatment for acne.

Benzamycin (Benzoyl Peroxide / Erythromycin) is a topical combination acne treatment that may work better for people who didn't see an improvement when taking either medicine alone or simply don't want to take pill medication. You need to be careful because it can bleach your hair, clothing and other fabrics. It also needs to be stored in the refrigerator and is only good for three months..

Upsides
  • First choice medicine to treat many bacterial infections.
  • Available in generic.
  • Available in different forms: tablet, capsule, and liquid. The liquid comes in many different flavors to make it taste better for people who don't like pills.
  • Side effects are generally not too bad compared to other antibiotics.
  • Benzamycin works better to reduce bacteria in oil glands and improve overall signs and symptoms of acne than either medicine alone.
  • Reduces bacteria on the skin, which "calms" the skin down (lowers the inflammatory response) in acne.
  • Combining an antibiotic with benzoyl peroxide lowers the chances of Benzamycin not working as well over time.
  • Although Benzamycin can irritate the skin, a true skin allergy is rare.
  • Can be used in combination with acne pill medicine if your doctor thinks you need it.
Downsides
  • While Amoxil (amoxicillin) can be used to treat different bacterial infections, many don't respond to it.
  • Can cause diarrhea, nausea, and vomiting.
  • Except for the extended-release form, you have to take Amoxil (amoxicillin) 2 to 3 times a day, which can be hard to remember.
  • The extended-release form can be more expensive because it's a brand name.
  • There's a risk of irritation with anything you apply to your skin and this is no different. Benzamycin, contains a topical antibiotic and can cause redness, peeling, abnormal dryness or stinging, tightening, or burning sensations.
  • It's rare, that a serious allergic reaction would occur, but it's a good idea to test a small area of skin before using on any larger or sensitive areas
  • Can cause severe inflammation of the large intestine (pseudomembranous colitis).
  • Not the best choice if you're pregnant. Benzamycin is categorized as pregnancy Category C (weight risks vs benefits) because of the benzoyl peroxide part.
  • Can cause bleaching of hair and clothing.
  • You'll need to stay out of the sun or apply a sunscreen if you go outdoors.
