1. What Fasigyn is and what it is used for

Fasigyn contains a substance called tinidazole that kills certain bacteria and protozoa(unicellular organisms ) without damaging human tissue.

Fasigyn is used in the treatment of infections caused by certain bacteria or protozoa, e.g. Trichomonas vaginalis. These infections can occur in the intestines as well as in the genitals of both men and women.

Tinidazole contained in Fasigyn may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

2. What you need to know before using Fasigyn

  • in case of a certain pathological change of the blood (blood dyscrasia )
  • during the first three months of pregnancy (first trimester) or if you are trying to conceive (see section Pregnancy, breast-feeding, and fertility ).

Fasigyn with food, drink, and alcohol

Fasigyn should if possible be taken in conjunction with, or shortly after a meal.

Alcohol consumption should be avoided. If alcohol is consumed during treatment and up to 3 days (72 hours) after treatment, it can cause several unpleasant symptoms, e.g. redness, abdominal cramps, vomiting, and palpitations.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Fasigyn should not be used during the first three months of pregnancy (first trimester). It should only be used during the last six months of pregnancy (the second and third trimesters) if your doctor deems it necessary.

The active substance tinidazole is excreted in human milk. Children who are breastfed may be affected. You should not breast-feed while taking Fasigyn and for at least 3 days after stopping treatment.

Driving and using machines

No studies have been performed, but to date, there is no evidence that Fasigyn affects the ability to drive or use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these

effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

Fasigyn contains sodium

3. How to use Fasigyn

Always take this medicine exactly as your doctor or pharmacist has told you. Ask your doctor or pharmacist if you are unsure.

Dose one is determined by the doctor, who adjusts it individually for you. The size of the dose and the duration of treatment are different depending on the infection being treated. After just a few days, the symptoms may subside. However, the entire course must be completed. Otherwise, there is a risk that infection will return.

Infection of Trichomonas vaginalis in the vagina in women is usually treated with a single dose. The sexual partner is also treated, as he or she can be infected without having any symptoms.

Fasigyn should if possible be taken in conjunction with, or shortly after a meal.

If you use more Fasigyn than you should
