What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Erythrocin (erythromycin) is an antibiotic prescribed to treat different infections. Some of the infections treated include:

  • Acute pelvic inflammatory disease
  • Diptheria
  • Intestinal amebiasis
  • Legionnaires Disease
  • Lower respiratory infections
  • Pertussis
  • Sexually transmitted infections
  • Skin and skin structure infections
  • Upper respiratory infections

Erythromycin works by stopping bacterial growth. It binds to the 50S ribosomal subunit of bacteria, blocking the production of necessary proteins.

Directions

There are different formulations of erythromycin tablets that are made with different ingredients.

The standard dosage is based on the amount of "erythromycin base" in the tablet.

The normal dosage is 250-500 mg of erythromycin base every 6 to 12 hours as directed by the doctor. Do not take this medication for longer than prescribed by the doctor.

The directions can be very different depending on the type of infection, so follow the directions from the doctor closely.

Ingredients

The active ingredient in erythrocin is erythromycin.

Interactions

Erythromycin is a potent inhibitor of the metabolic enzyme CYP3A4. Other drugs that are metabolized by this enzyme can increase to dangerous levels when taking together with erythromycin. Tell your doctor all the medications you are taking before starting erythromycin.

Some examples of drugs that interact with erythromycin include:

  • Antibiotics
  • Anticoagulant medications
  • Antineoplastic agents (chemotherapy)
  • Calcium channel blockers
  • Carbamazepine
  • Cilostazol
  • Cobicistat
  • Colchicine
  • Eplerenone
  • Everolimus
  • Fentanyl
  • Guanfacine
  • Ibrutinib
  • Lurasidone
  • Methadone
  • Sleep medications
  • Statin medications
  • Theophylline

This is not a complete list of drug interactions. Erythromycin reacts with many other medications and your doctor should review your entire list of medications.

Cautions

Erythromycin should never be taken unless a doctor confirms a bacterial infection. Taking it without a confirmed infection can cause side effects like antibiotic resistance and gastrointestinal side effects.

Erythromycin can cause heart arrhythmias, so tell your doctor if you have a history of this condition.

Tell your doctor if you have a history of liver impairment or liver disease.

Side Effects

The most common side effects of erythromycin include:

  • Abdominal pain
  • Anorexia
  • Convulsions
  • Diarrhea
  • Heart arrhythmias
  • Nausea
  • Pancreatitis
  • Symptoms of hepatitis
  • Vomiting
