1. What is Fortasec Plus and what is it used for

The tablets contain two active ingredients:

  • Loperamide hydrochloride, helps reduce diarrhea by decreasing intestinal activity. It also helps absorb more water and salts from the intestine.
  • Simethicone, breaks down trapped air in the intestine, which causes cramps and bloating.

Fortasec Plus is used in adults and adolescents from 12 years old for the treatment of diarrhea when associated with stomach cramps, bloating, and gas.

2. What you need to know before starting to take Fortasec Plus

Do not take Fortasec plus:

  • In children under 12 years old
  • If you are allergic to loperamide hydrochloride, simethicone, or any of the other components of this medication included in section 6.
  • If you have a high fever (above 38°C) or blood in your stool.
  • If you suffer from intestinal inflammation such as ulcerative colitis.
  • If you have severe diarrhea after taking antibiotics.
  • If you are constipated or if you experience stomach bloating.

Warnings and precautions:

Consult your doctor or pharmacist before starting to take Fortasec plus

  • Fortasec plus only treats the symptoms of diarrhea. In some cases, the cause of the diarrhea may require treatment. If the symptoms persist or worsen, consult your doctor. If you have severe diarrhea, your body loses more fluids, sugars, and salts than normal, and you will need to replenish them by drinking more than usual. Ask your pharmacist about preparations to replenish sugars and salts.
  • If you have AIDS and your stomach becomes bloated, stop taking the tablets immediately and consult your doctor.
  • If you have liver disease, consult your doctor before taking the tablets.

Some of the adverse reactions may be more bothersome.

Do not take this medication for a use other than indicated (see section 1) and never take more than the recommended amount (see section 3). Serious heart problems (whose symptoms include rapid or irregular heartbeats) have been reported in patients who have taken an excessive amount of loperamide, one of the active ingredients of Fortasec plus.

In acute diarrhea, the symptoms usually disappear within two days. If the symptoms persist after this period, stop treatment and consult your doctor.

Important information about some ingredients of Fortasec Plus:

Each Fortasec Plus tablet contains less than 0.026 mg of benzyl alcohol. Benzyl alcohol may cause allergic reactions. Consult your doctor or pharmacist if you have any liver or kidney disease, or if you are pregnant or breastfeeding. Large amounts of benzyl alcohol can accumulate in your body and cause side effects (called "metabolic acidosis").

This medication contains less than 1 mmol of sodium (23 mg) per tablet, i.e., it is essentially "sodium-free".

This medication contains less than 0.00044 mg of alcohol (ethanol) per tablet. The small amount of alcohol in this medication will not have any noticeable effect.

This medication contains maltodextrin, which contains glucose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

Children

  • Ritonavir (used to treat HIV and AIDS)
  • Desmopressin (used to control thirst and urine production in patients with diabetes insipidus)

Tell your doctor or pharmacist if you are using or have recently used other medications, even those purchased without a prescription, because Fortasec plus tablets may interact with them.
