General Information on Flagyl
Flagyl is used to treat and prevent several types of infections caused by bacteria. It is also used to treat protozoan and certain bacterial infections caused by anaerobic bacteria after surgery of the gut and gynecological surgery. The generic name of this drug is Metronidazole.
Metronidazole, the main active ingredient in the drug belongs to a family of drugs known as Nitroimidazoles. It enters the bacterial cells and destroys DNA of infection-causing bacteria, preventing the bacterium from developing new genetic structure. This, in turn, leads to the death of the micro-organisms.
Flagyl is available in the form a tablet and an oral suspension. The tablet is available in two different strengths, Flagyl 200mg and Flagyl 400mg, while the oral suspension is available in 200mg/5mL strength.
You can buy Flagyl to treat bacterial infections. The drug will only work to cure infections caused by bacteria and specific micro organisms. It does not cure viral infections or infections caused by other microorganisms. Therefore, you should consult your doctor before using the medication.
Side effects of Flagyl
You should not use Flagyl if you are allergic to any ingredient present in the drug. People with medical problems such as Crohn’s disease, liver disease, leukopenia, anemia, nerve disorders, or epilepsy or other seizure disorders should tell their doctor about their medical condition before using the drug. Your doctor may have to perform special tests and/or adjust the dosage to ensure that the drug is safe in these conditions.
Flagyl may cause mild to severe side effects in some people. Diarrhea, loss of balance, stomach pain, dizziness, unpleasant metallic taste, stuffy or runny nose, sneezing, cough, sore or swollen tongue, or vaginal itching or discharge are some less serious side effects associated with this drug.
Some people may also experience severe side effects during treatment. Numbness/tingling sensation in your feet or hands, pain or burning sensation while passing urine, watery or bloody diarrhea, sores or white patches on your lips or inside your mouth, pain behind your eyes or vision problems, or mood or behavior changes are some severe side effects associated with this drug.
Flagyl may also cause other serious side effects such as slurred speech, vomiting and nausea, seizure, muscle twitching, confusion, fever, chills, neck stiffness, increased sensitivity to light, drowsiness, or severe skin reactions (such as blistering or peeling of the skin or purple or red rash that spreads in the upper body area or face).
Dosage of Flagyl
The dosage of Flagyl differs from person to person. Your doctor will give you specific instructions regarding the dosage. Swallow the tablet whole with a glass of water during or after your meal.
If you are using Flagyl oral suspension, you need to take the recommended dose, at least, 1 hour before meal. The dosage of tablets and oral suspension is generally recommended for 7 days. Do not take the medication in larger quantity or for longer periods than recommended by your doctor.

Flagyl may interact with medicines such as Warfarin, Antabuse(R), some anticancer drugs, Phenytoin, Cimetidine, Phenobarbitone, Lithium, and Cyclosporin. Before you buy Flagyl, tell doctor about every medication that you are using to reduce the risk of unwanted drug interactions.

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.
