About tinidazole
Type de médicament | An antimicrobial medicine |
Utilisé pour | To treat infection and before surgical operations to prevent infection |
Aussi appelé | Fasigyn® (discontinued) |
Disponible sous forme de | Comprimés |
Tinidazole is used to treat a variety of infections which can be caused by types of germs known as anaerobic bacteria and micro-organisms (protozoa). These types of organisms often cause infections in areas of the body such as the gums, the pelvic cavity, and the tummy (abdomen) because they do not need oxygen to grow and multiply. It is also prescribed before gynaecological surgery and surgery on the intestines, to prevent infection from developing. Tinidazole can be taken by people who are allergic to penicillin.
Occasionally, tinidazole is also prescribed as part of a treatment to get rid of Helicobacter pylori. This is a bacterial infection which is often associated with stomach ulcers.
Before taking tinidazole
Retour au sommaireSome medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking tinidazole it is important that your doctor knows:
Si vous êtes enceinte ou si vous allaitez.
If you drink a lot of alcohol.
Si vous avez un trouble sanguin héréditaire rare appelé porphyrie.
Si vous prenez ou utilisez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et complémentaires.
Si vous avez déjà eu une réaction allergique à un médicament.

How to take tinidazole
Retour au sommaireBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about tinidazole, and will also provide you with a full list of side-effects which you could experience from taking it.
Take the tablets exactly as your doctor tells you to; the dose you are given will depend upon what type of infection you have. As a guide, a single dose of four tablets taken at the same time is sufficient for most vaginal or dental infections in adults. For other bacterial infections, you are likely to be asked to take a course of treatment which could last up to seven days. Your doctor will tell you what dose is right for you (or your child) and this information will also be printed on the label of the pack of tablets to remind you about what the doctor said.
Keep taking the tablets every day until the course is finished (unless your doctor tells you to stop sooner). This is because your symptoms could return if you stop taking tinidazole before the end of the course.
Take the tablet at a mealtime, or with a snack. Swallow the tablet with a drink of water. Do not chew or break the tablet before you swallow it.
Try to take your doses at the same time of day each day, as this will help you to remember to take tinidazole regularly. If you do forget to take a tablet, take it as soon as you remember. If you do not remember until the following day, leave out the forgotten dose from the previous day and take the dose that is due as normal. Do not take two doses on the same day to make up for a missed dose.
Tirer le meilleur parti de votre traitement
Retour au sommaireImportant: do not drink alcohol while you are on tinidazole and for three days after finishing your course of treatment. This is because drinking alcohol with tinidazole is likely to make you feel very sick and cause other unpleasant effects.
If you buy any medicines, check with a pharmacist that they are safe to take with tinidazole. Some cough and cold preparations contain alcohol and should not be taken with the tablets.
If you need to take tinidazole for longer than ten days, your doctor will want you to have some tests. Make sure you keep any appointments that your doctor gives to you.
This medicine can stop the oral typhoid vaccine from working properly. If you are due to have any vaccinations, make sure the person treating you knows that you are taking tinidazole.

Questions fréquemment posées
What kind of infections does tinidazole treat?
Tinidazole is effective against infections caused by specific types of germs called anaerobic bacteria and micro-organisms (protozoa). These organisms thrive without oxygen and commonly lead to infections in areas like the gums, pelvic region, and the tummy (abdomen). It is also used to prevent infections before gynaecological or intestinal surgery. Additionally, it can be part of the treatment for Helicobacter pylori, a bacterial infection often linked to stomach ulcers.
Can I take tinidazole if I have a penicillin allergy?
Yes, tinidazole can be taken by individuals who are allergic to penicillin.
How long will I need to take tinidazole?
The duration of your tinidazole course depends on the type of infection you have. For most vaginal or dental infections in adults, a single dose of four tablets may be sufficient. For other bacterial infections, treatment might last up to seven days. Your doctor will provide specific instructions for your condition, which will also be printed on the tablet packaging.
What should I do if I forget to take a dose of tinidazole?
If you miss a dose, take it as soon as you remember. However, if you don't remember until the next day, you should skip the forgotten dose from the previous day and take your next scheduled dose as normal. Do not take two doses at the same time to compensate for a missed dose.
Are there any specific foods or drinks I should avoid while taking tinidazole?
It is crucial not to drink alcohol while you are taking tinidazole and for three days after you finish your course of treatment, as this can cause severe sickness and other unpleasant effects. If you experience nausea or vomiting, sticking to simple foods and avoiding hot or spicy meals can help.
Can tinidazole affect other medicines or vaccines?
Yes, tinidazole can prevent the oral typhoid vaccine from working effectively. If you are scheduled for any vaccinations, make sure the person administering them knows you are taking tinidazole. Also, some cough and cold remedies contain alcohol, so you should check with a pharmacist if any over-the-counter medicines are safe to take with tinidazole.
