Iberogast is a herbal medicinal product used for the treatment of functional gastrointestinal disorders related to the motility of the gastrointestinal tract, such as functional dyspepsia or irritable bowel syndrome. These disorders are mainly characterized by abdominal and intestinal cramps, abdominal pain, feeling of fullness, bloating, nausea, and heartburn.
Iberogast alleviates the feeling of fullness, bloating, and reduces stomach and intestinal cramps. It has anti-inflammatory, carminative, antioxidant, and antibacterial properties.

It is not recommended for children under 6 years of age. In children under 6 years of age, any abdominal pain should be consulted with a doctor.
If the patient has or has had liver disease or is taking medicines that, according to the patient information leaflet, may cause side effects in the form of liver damage. In case of any doubts, the doctor or pharmacist should be consulted.

Warnings and precautions

If the patient experiences yellowing of the skin or eyes, dark urine, pale stools, or abdominal pain, the use of Iberogast should be stopped immediately and a doctor consulted. These may be symptoms of liver damage.
Patients with diagnosed liver disease should consult a doctor before starting to use Iberogast.

Iberogast and other medicinal products

The doctor or pharmacist should be informed about all medicinal products currently being taken or recently taken by the patient, as well as any medicinal products that the patient plans to take.
No interactions are known.

Due to the alcohol content, Iberogast is not intended for and should not be used by individuals with alcohol dependence.
Iberogast contains ethanol (alcohol) at a volume concentration of approximately 31%. A single dose for adults (20 drops) contains up to 240 mg of ethanol, which corresponds to approximately 6.2 ml of beer or 2.6 ml of wine per dose.
Children and individuals at high risk, including patients with liver disease or epilepsy, should consult a doctor before using Iberogast.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks she may be pregnant, or plans to have a child, she should consult a doctor or pharmacist before using this medicinal product.

Use of a higher than recommended dose of Iberogast

There are no reports of acute overdose. However, the alcohol content should be considered.
Accidental ingestion of one or two doses of Iberogast more than recommended, i.e., a total of 40 to 60 drops, usually does not lead to negative consequences. In the case of ingestion of significantly larger doses, a doctor or pharmacist should be consulted for help.

Missed dose of Iberogast

Frequency not known: cases of liver damage (increased liver function test values, drug-induced jaundice, hepatitis, and liver failure) have been reported; if symptoms such as yellowing of the skin or eyes, dark urine, and pale stools occur, Iberogast should be stopped immediately and a doctor consulted.
