Metronidazole is an antibiotic medicine. It belongs to a category of treatments which target anaerobic bacteria and protozoa, and is indicated for a number of different infections. Among these is trichomoniasis. The medication is supplied in standard tablet form. It is a generic version of the treatment which is also available here as Flagyl (marketed by Zentiva).

- Available as an oral suspension
Trichomoniasis is a type of STI (sexually transmitted infections). It is caused by a parasite called trichomonas vaginalis, which can be passed from one individual to another through unprotected vaginal or oral sex, or through the use of sex toys. Symptoms of the illness are different depending on the gender of the person infected. In women, these might include an inflamed or sore vagina, urinary pain, yellow-green vaginal discharge or lower abdominal pain. For men, the condition might be characterised by pain during urination, inflammation of the tip of the penis, and white discharge. However, half of men and women with the condition may have no symptoms at all.
Metronidazole works by stopping the bacteria or protozoa which causes the infection from spreading. It does this by inhibiting the synthesis of certain acids, which the cells of the offending bacteria or parasite need to increase their presence in the body. When these cells are prevented from achieving further growth, they become susceptible to attack from the immune system, which then fights the infection off.
You cannot purchase Metronidazole from our online service. If you want to find out if you require this treatment, make an appointment with your doctor.
The main functioning component of this medication is Metronidazole. This treats bacterial infections and those caused by certain protozoa by inhibiting their growth. To increase in number, these bacteria require the presence of nucleic acid. This enables them to function and reproduce.
Once the production of this acid has been obstructed, the cells of the offending bacteria can no longer develop and come to a standstill. This leaves them open to attack from the body’s natural defences, which destroys the infection and clears symptoms.
To get the most out of Metronidazole and reduce the likelihood of side effects, ensure you follow the directions your prescriber provides. It is always advisable to read the patient information leaflet and familiarise yourself with the safety instructions prior to first use.
