Tinidazole is a tablet that kills both bacteria and protozoa, the single-celled parasites such as the one behind trichomoniasis. It is swallowed, spreads through the whole body, and is taken for days at most. PockDose sells it as plain Tinidazole tablets at 500mg.

What tinidazole is used for

The infections it treats are mostly in the gut and genital tract. Trichomoniasis, a sexually transmitted infection, usually causes vaginal discharge and sometimes itching or pain when passing urine. Giardiasis is caught from contaminated water or food, and intestinal amoebiasis brings diarrhoea and stomach cramps. Bacterial vaginosis, where the balance of bacteria in the vagina shifts, is also treated with it, as are infections caused by anaerobic bacteria, the kind that thrive without oxygen.

How it works

Tinidazole only becomes active once it is inside the parasite or bacterium. There, in a low-oxygen setting, it is broken into compounds that cut up the organism's DNA, and without intact DNA it cannot multiply. Human cells do not have that low-oxygen chemistry, which is why the drug picks out these organisms and leaves the patient's own cells alone.

Taking the tablets

Take tinidazole with food; it sits more comfortably on the stomach that way. How long you take it depends on the infection — trichomoniasis and giardiasis usually clear with a single dose, while amoebic and anaerobic bacterial infections need several days of once-daily tablets. Swallow them with water. Keep the tablets in their foil until you need them, somewhere dry and out of direct sun.

Two things to know while you are on it. Alcohol reacts badly with tinidazole, bringing on flushing, nausea, vomiting, headache and a pounding heartbeat. And taken alongside warfarin, a blood thinner, tinidazole increases the blood-thinning effect, so bruising and bleeding become more likely.

Side effects

The effect most people mention is a metallic taste, followed by nausea, stomach ache, diarrhoea, headache and dizziness. All of these tend to be mild and clear up when the course ends. Tingling or numbness in the hands and feet is less usual, and seizures are reported only rarely. Swelling of the mouth or throat with difficulty breathing is an allergic reaction and needs emergency care.

What are the brand names for tinidazole?

Tinidazole is sold under brand names including Fasigyn, Tindamax and Tiniba. Here, tinidazole can be bought online as tinidazole tablets. These are generics, not the original brand.

How does tinidazole compare with metronidazole?

Both belong to the same nitroimidazole family and are used for the same kinds of infection. Tinidazole stays in the body longer, so trichomoniasis and giardiasis can be cleared with a single dose instead of tablets taken over several days. Metronidazole has been in use for longer of the two.

Can I drink alcohol with tinidazole?

No. Alcohol while the tablets are working causes flushing, nausea, vomiting, headache and a fast heartbeat. The reaction can still be triggered for about three days after the last tablet, so it is safest to stay off alcohol until that window has passed.

How many tinidazole tablets will I need?

It depends on the infection. Trichomoniasis and giardiasis are usually treated with a single 2g dose, which is four of the 500mg tablets. Amoebic infections run for several days instead, so a pack of 500mg tablets lasts longer.

What side effects can tinidazole cause?

A metallic taste is the most common one, and nausea, stomach cramps, diarrhoea, headache and dizziness are all reported. Tingling or numbness in the hands or feet is less common. Most of these are mild and ease once the tablets are stopped.

Can trichomoniasis come back after treatment?

It can, if a sexual partner still has the infection. Most men with trichomoniasis have no symptoms at all, so it can pass back and forth unnoticed. Clearing both partners at the same time is what stops the round trip.
