CODEX*12CPS 5BLN 250MG

Codex 5 billion hard capsules
Saccharomyces boulardii

What it is and what it is used for
Codex contains the active substance Saccharomyces boulardii, a yeast.

This medicine is used for the following conditions:
- prevention and treatment of alterations to the normal balance of the intestinal bacterial flora (intestinal dysbiosis);
- prevention and treatment of diarrhoea related to intestinal dysbiosis.

Consult your doctor if you do not feel better or if you feel worse.

What you need to know before taking the medicine
Do not take Codex
- if you are allergic to Saccharomyces boulardii or any of the other ingredients of this medicine (listed in section 6);
- if you are allergic to yeasts;
- if you have a central venous catheter (a catheter for administering fluids directly into a central vein);
- if you are being treated with medicines for fungal infections (see "Other medicines and Codex");
- if you are an immunocompromised patient or hospitalised (due to severe illnesses or with an altered/weakened immune system).

Warnings and precautions
Consult your doctor or pharmacist before taking Codex.

During treatment for diarrhoea, ask your doctor about fluid intake (hydration) and its route of administration, as rehydration needs must be determined based on the severity of the diarrhoea, your age and your general health condition.

As with all medicines containing living microorganisms, pay particular attention to the handling of this medicine in the presence of patients with a central venous catheter (a catheter for administering fluids directly into a central vein). Avoid any contact between Codex and the catheter (including airborne spread of spores), as the active substance (the fungus Saccharomyces boulardii) can enter the bloodstream and replicate quickly, leading to an infection.
Indeed, in patients with a central venous catheter, even if not treated with Saccharomyces boulardii, very rare cases of fungaemia (spread of yeast in the blood) have been reported, which often manifests with fever and positive tests for Saccharomyces strains. All these cases resolved favourably following treatment with medicines against fungi (antifungals) and, where necessary, removal of the catheter.
