More facts about Generic Flagyl (Metronidazol 200 mg):

What is the product sold as Flagyl?

What is the product sold as Flagyl?

The brand name Flagyl is owned by a pharmaceutical company Sanofi Avensis. The same medication is also made and marketed by other pharmaceutical companies under the brand and generic names. For instance, in the U.S. it is sold under the same name Flagyl but it is made by Pfizer. Besides, the medication is made by numerous manufacturers such as Cipla, Abbott, and others and can be called differently. Some of the names under which you can find the same medication are Metrogyl, Metronidazole, Acromona, Clont, Cont, Monasin, Nalox, Neo-Tric, Nidagel, Noritate, Novonidazol, Orvagil, Protostat, Rathimed, Trichazol, Trichex, Tricho Cordes, Trichopol, and others. It is possible because the original substance was synthesized first in the 1960s and since then, the developer of the medication, a French pharmaceutical company Rhone-Poulenc had lost their exclusive rights to make the medication without sharing the formula with other drug makers. It is a common practice all around the world that after a certain period of time, the formula developer is obliged to give out the formula and other drug makers can make and sell their medicines with the same composition and effect without infringing the copyrights. It is made so to satisfy the world’s demand for the medications and make the drugs cheaper for the countries with lower average incomes.

Nowadays the medication is prescribed for the treatment of protozoal infections, infections of bones and joints, nervous system infections, sexually transmitted infections, vaginal infections due to a surgery, and so on. To treat these conditions you can buy Flagyl or opt for a generic with the active ingredient being Metronidazole.

Metronidazole, the active agent of Flagyl, is a synthetic derivative of the natural substance of azomycin, produced by Streptomyces spp. When first utilized in healthcare, the substance was considered exclusively an antiprotozoal agent for the treatment of trichomoniasis. The antibacterial effect of the medication was discovered by chance: when in 1962 a patient with trichomoniasis colpitis using Metronidazole had been cured of bacterial gingivitis.

How Flagyl acts?

The medication renders antibacterial, antiulcer, antialcoholic, antiprotozoal, anti-trichomoniasis, and antimicrobial effects.

The nitro group of the molecule, which is an electron acceptor, is built into the respiratory chain of protozoa and anaerobes (competing with electron transport proteins - flavoproteins, etc.), which disrupts respiratory processes and causes cell death. In addition, some species of anaerobes have the ability to suppress DNA synthesis and cause its degradation.

After the pill is taken orally, the active agent is quickly and fully absorbed from the digestive tract. The maximum level of the medication in the tissues is observed within one to three hours. It penetrates the tissues and fluids of the body well creating bactericidal concentrations in saliva, semen, vaginal secretions; penetrates the GEB and placental barriers, is secreted into breast milk.

People with impaired kidney function can accumulate the medication in the blood plasma. Therefore, it is advised to use lower doses or take the medication less frequently if creatinine clearance is lowered.

Can you replace the brand-name drug with Generic Flagyl?

Yes, without any doubts you can buy Generic Flagyl when your doctor prescribes you the brand-name medication because exactly the same medication is manufactured by numerous different companies who set the lower prices per pill.

You can use the medication as you would use the branded one but to be sure that you follow the right dosage regimen, make sure to check the dose of Metronidazole per pill.

When can you purchase Metronidazole?

You can buy Metronidazole only if an infection that caused your malaise is confirmed to be caused by a pathogen that is sensitive to the active agent of the drug. The medication is appointed to be used in infections caused by microorganisms that are sensitive to it such as amebiasis; genitourinary trichomoniasis; nonspecific vaginitis; giardiasis; infections caused by anaerobic microorganisms sensitive to Metronidazole that develop after surgery. Besides, the drug can be utilized as a substitute for intravenous treatment of infections caused by anaerobic microorganisms that are sensitive to it.

In some cases, when a doctor analyzes the results of your tests, he or she can prescribe you to use the medication without doing a susceptibility test as the full blood test will show the names of pathogens and an experienced doctor knows if they are or not sensitive to Metronidazole. In any case, before you purchase the pills to start the treatment, make sure to do all necessary tests.

When shouldn’t you buy Metronidazole?

Even if the tests show that you need the treatment with this medication, you should not use it if you are hypersensitive to the drug’s components or other derivatives of nitroimidazole, suffer or ever suffered from leukopenia, have organic diseases of the central nervous system (epilepsy), have hepatic insufficiency (the high doses are contraindicated).

You must not buy Generic Metronidazole and use it during the first three months of pregnancy, while you breastfeed, or give it to children without consulting a pediatrician first.

The drug is not advised to be used in any liver dysfunctions including the mild ones, in severe kidney dysfunction, central nervous system disorder, and during the second and third trimesters of pregnancy.

What negative effects can you expect from Generic Flagyl use?

The use of both brand-name Flagyl and its generic can cause minor gastrointestinal disorders such as epigastric pain, nausea, vomiting, diarrhea, glossitis with dry mouth, stomatitis, taste disorders, anorexia; pancreatitis; flushes, itching of the skin, rash, in some cases accompanied by an increase in body temperature, urticaria, angioedema, anaphylactic shock, and others.
