General Information on Eryc
Eryc is used for the prevention and treatment of certain bacterial infections, including Legionnaires’ disease, non-gonococcal urethritis, acute pelvic inflammatory disease, intestinal amebiasis, syphilis, erythrasma, diphtheria, pertussis, and listeriosis.
The generic name of the drug is Erythromycin, and it falls under the class of macrolide antibiotics. Eryc is available in the form of oral capsules.
Eryc stops the growth and spread of bacteria in the body, thus treating the bacterial infection. It is meant only for bacterial infections, so you should not buy Eryc to treat a viral or yeast infection.
Side effects of Eryc
Before you buy Eryc, inform you doctor if you have an allergy to Erythromycin or any other antibiotic. Also inform him/her if you are suffering from a kidney or liver disease, heart problem (e.g. heart failure), muscle disease (e.g. myasthenia gravis), QT prolongation in EKG, slow heartbeat, or if your family has a history of sudden cardiac death. In such circumstances, your doctor may need to conduct some special tests or make some necessary dosage adjustments. Breastfeeding mothers should also not use Eryc as it may pass into breast milk and harm the nursing baby.
Elderly patients should use Eryc with caution, as serious side effects are more likely to occur in their cases, especially when they suffer from hearing loss and irregular heartbeat. If you have low magnesium or potassium levels in your blood, you may be more susceptible to suffering from QT prolongation as a side effect of Eryc.
Some common side effects associated with Eryc include nausea, vomiting, diarrhea, stomach pain and cramping, heartburn, and loss of appetite. Although these are mild side effects of the drug, you should seek medical help if any of these become intolerable.
Inform your doctor immediately if you suffer from severe dizziness, fainting, mouth sores, persistent nausea or vomiting, severe abdominal or stomach pain, unusual weakness, dark urine, yellowing of the eyes or skin, muscle weakness, hearing loss, seizures, or fast or irregular heartbeat after taking Eryc. These may be signs of a serious underlying condition, and you need to get them treated as soon as possible.
In rare instances, Eryc may lead to clostridium difficile associated diarrhea, a serious intestinal condition. Symptoms of this condition include blood or mucus in the stools, stomach or abdominal pain or cramping, and persistent diarrhea. Inform your doctor immediately if you suffer from any of these symptoms during Eryc treatment.
Some patients may suffer from an allergy to Eryc, the signs of which include hives, facial swelling, difficulty breathing, or severe dizziness. Seek medical help if you have any of these symptoms and if they do not subside even after discontinuing the medication.
Dosage of Eryc
Your doctor may advise you to take Eryc 250mg four times a day or Eryc 500mg twice a day. You should take the drug on an empty stomach, but if you experience nausea, you can take it along with food or milk.
Swallow the Eryc capsule whole without crushing, breaking, or chewing it. Try to take the drug at almost the same time each day.

What is a "Generic" medication/drug?
Generic drugs are medications that have the comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo comparative testing to ensure that they are the same as their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain comparable active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must be comparable in strength and dosage to the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically comparable. They may look different, and be called something different, but they are required to be have the same active ingredient.
How are Generic drugs tested to ensure quality and efficacy?
The two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
