What Trevis is and what it is used for

Trevis is a natural remedy that contains lactic acid bacteria. To some extent, the bacteria reach the small and large intestines and are considered to influence the intestinal flora there through various mechanisms.

Trevis is traditionally used for the normalization of the intestinal flora in temporary stomach/intestinal disturbances, such as mild diarrhea and constipation, as well as for the treatment and prevention of common uncomplicated tourist diarrhea.

What you need to know before using Trevis

Do not use Trevis

  • if you are allergic to cow’s milk, as Trevis contains skimmed milk powder.
  • if you are allergic to Lactobacillus acidophilus, Bifidobacterium animalis, Lactobacillus bulgaricus, Streptococcus thermophilus, or any other ingredient in this medicine (listed in section 6).

Warnings and precautions

IMPORTANT: Always call a doctor if:

  • diarrhea lasts for more than 2 days
  • the stool is bloody
  • you have a high fever

Especially children and the elderly can become seriously ill from the fluid loss that diarrhea brings with it. If you are in an area with, for example, typhoid and cholera, you should in any case seek medical attention in case of diarrhea.


Trevis is not recommended for children under 8 years of age.

Other medicines and Trevis

Lactic acid bacteria, like other bacteria, are sensitive to antibiotics, which is why Trevis and antibiotics should be taken at least 3 hours apart.

The effect of simultaneous intake of other medicines or food has not been studied.

When contacting a doctor or other healthcare professional, remember to mention that you are taking or have recently taken Trevis.

Pregnancy, breastfeeding, and fertility

Trevis can be used by breastfeeding women.

The drug’s potential impact on fertility and pregnancy has not been studied.

Driving ability and use of machinery

Trevis has no or negligible effect on the ability to drive and 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. Discuss with your doctor or pharmacist if you are unsure.

How to use Trevis

Always use this medicine exactly as described in this leaflet or as directed by your doctor or pharmacist. Ask your doctor or pharmacist if you are unsure.

You can further reduce the risk of tourist diarrhea by being careful with food and drink and hygiene. Be aware that diarrhea can be a sign of something other than a tourist’s stomach. If, despite all safety measures, you experience diarrhea, remember to drink plenty of fluids. If you drink water, remember that it should be bottled mineral or drinking water or boiled for a few minutes.

Contact a doctor if you do not feel better or if you feel worse after 2 days.
