Patient leaflet - Hidrasec children 30 mg granules for oral suspension

1. What Hidrasec is and what it is used for

Hidrasec is a medicine for the treatment of diarrhoea.

Hidrasec is used for the treatment of symptoms of acute diarrhoea in children over three months of age. It should be used together with an abundant liquid intake and the usual dietary measures, when these measures are not sufficiently effective on their own to control the diarrhoea, and when diarrhoea cannot be treated causally.

Racecadotril can be administered as a complementary treatment when causal treatment is possible.

2. What you need to know before you take Hidrasec

Do not use Hidrasec

  • If your child is allergic to racecadotril or any of the other ingredients of Hidrasec (listed in section 6).
  • If you have been told by your doctor that your child has intolerance to some sugars, ask your doctor before you give Hidrasec to your child.
  • If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking racecadotril.

Warnings and precautions

Talk to your doctor or pharmacist before giving Hidrasec to your child if:

  • Your child is under three months of age,
  • There is blood or pus in your child stools and if he/she has fever. The cause of the diarrhoea may be a bacterial infection that should be treated by your doctor,
  • Your child is suffering from chronic diarrhoea or diarrhoea caused by antibiotics,
  • Your child is suffering from kidney disease or impaired liver function,
  • Your child is suffering from prolonged or uncontrolled vomiting,
  • Your child is suffering from diabetes (see “Important information about some of the ingredients of Hidrasec”).

Occurrence of skin reactions has been reported with the use of this product. These are in most cases mild and moderate. When experiencing severe skin reactions, the treatment has to be stopped immediately.

Take special care with racecadotril:

Serious skin reactions including drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with racecadotril treatment. Stop using racecadotril and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

Other medicines and Hidrasec

Please tell your doctor if your child is using, has recently used or might use any other medicine.

Especially tell your doctor if your child use any of the following medicines:

  • ACE inhibitor (e.g. captopril, enalapril, lisinopril, perindopril, ramipril) used to lower the blood pressure or facilitate heart labour.

Pregnancy, breast-feeding 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.

Use of Hidrasec is not recommended in case of pregnancy and breast feeding.

Driving and using machines

Hidrasec has little or no effect on the ability to drive and use machinery.

Hidrasec contains sucrose

Hidrasec contains about 3 g of sucrose per sachet.

If you have been told by your doctor that your child has intolerance to some sugars, ask your doctor before you give Hidrasec to your child.

In children with diabetes, the quantity of sucrose ingested with Hidrasec should be taken into account in the child’s total daily intake of sugar.

3. How to take Hidrasec

Always give Hidrasec to your child exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Hidrasec is supplied in the form of granules.

The granules should be added to food or mixed with water in a glass or baby bottle. Mix well and give immediately to your child.

The recommended daily dose depends on your child’s weight: 1.5 mg/kg per dose (corresponding to 1 to 2 sachets), three times daily at regular intervals.

In children weighing from 13 to27 kg: one sachet per dose.

In children of approximate weight more than 27 kg: two sachets per dose.

Your doctor will tell you how long the treatment with Hidrasec will last. It should be continued until your child has two normal stools, not exceeding 7 days.

To compensate for the loss of liquid due to your child’s diarrhoea, this medicinal product should be used together with an adequate replacement of fluid and salts (electrolytes). The best replacement of fluid and salts is achieved with a so-called oral rehydration solution (please ask your doctor or pharmacist if you are not sure).

If you give more Hidrasec than you should,

If your child has taken more Hidrasec than he/she should have contact your doctor or pharmacist immediately.

If you forget to give Hidrasec:

Do not give a double dose to your child to make up for a forgotten dose. Simply continue with the treatment.
