    • Adult and child doses vary, and a liquid solution makes giving the right person the right dose much simpler
    • Children and the elderly often prefer taking liquids. Some people find it difficult or unpleasant to swallow tablets
    • Liquid formulas are absorbed by the body quicker and more easily than tablets.
  • Some of the nine medicinal plants in Iberogast contain bitter substances, e.g. Iberis amara, also known as bitter candytuft (which accounts for the first part of the name to Iberogast). This is why many people experience the taste of Iberogast as bitter. However, as taste and smell are very subjective issues, the slightly bitter taste of Iberogast is experienced and rated differently with regard to strength. Those consumers who do not like a slightly bitter taste can take Iberogast as per the recommended dosage in sweetened tea or fruit juice before consuming the product.

  • If consumers are unsure whether they can use Iberogast for a prolonged period of time, they should ask their pharmacist or physician for advice. Consult a health care practitioner if symptoms persist or expected relief is not achieved within 7 days or for use beyond 4 consecutive weeks.

  • Iberogast can be diluted in cold or warm water, herbal or fruit tea, or juice. The slightly bitter taste of Iberogast, which is due to natural bitter substances contained in the medicinal plant extracts, can thereby be reduced. However, the temperature of the above-mentioned liquids should not be higher than 25°C. Grapefruit juice and alcoholic beverages are not suited for dilution because they can have a negative impact on the efficacy of Iberogast.

  • The efficacy, safety and tolerability of Iberogast have been studied in more than 20 scientific studies, involving more than 7,000 patients. Iberogast was well tolerated, however, hypersensitivity (e.g. allergy, skin reactions) has been known to occur. Unless advised by a health care professional, Iberogast should not be taken for a period beyond 4 consecutive weeks or during pregnancy or by breastfeeding mothers. Consult a health care practitioner before using if you have a peptic ulcer, liver disorder, epilepsy or if abdominal pain occurs in children under age 6. Iberogast contains 31% alcohol. Patients with illness related to alcohol should avoid Iberogast. Keep out of the reach of children. Do not use if you are allergic to ingredients in Iberogast.

  • Iberogast is indicated for use in children older than three years. The recommended dose for children aged three to six years is 10 drops, 3 times per day in some liquid before or with meals. For children between six and twelve years old, the recommended dose is 15 drops, 3 times per day. The total alcoholic content per single dose (10 drops or 15 drops) varies between 0.12 g and 0.18 g, respectively. By way of comparison, this is less than the alcohol content in a 200 ml glass of apple juice.

  • Unless advised by a health care professional, Iberogast should not be taken during pregnancy or by breastfeeding mothers.

  • After opening, Iberogast can be stored for at least 8 weeks. The reason is that some of the ingredients in the nine medicinal plants in Iberogast can only be found in the indicated amounts (specified on the pack and in the patient information leaflet) during the first eight weeks after opening the bottle.

  • Iberogast contains 31% alcohol because alcohol is used as an extraction medium for herbal extracts. The alcohol in Iberogast works as a ‘solvent’, preserving the nine medicinal plant extracts that contributes to Iberogast efficacy. For this reason, patients with illness related to alcohol should avoid Iberogast.

    A single adult dose of 20 drops contains just 0.24g of alcohol. By comparison, plenty of everyday foods and drinks contain small but higher volumes of alcohol. A glass of apple juice contains 0.3-0.7g and a slice of rye bread contains 0.3-0.4g.

  • Iberogast is manufactured to high quality standards. Bayer enforces the same manufacturing standards that apply to its other medicines. Iberogast is made with a patented production process and it also meets GMP standards. Medicinal plants used for Iberogast are cultivated and harvested under standardized and controlled conditions in accordance with Good Agricultural and Collecting Practice (GACP), ensuring consistent levels of active ingredients. Iberogast itself is also manufactured under standardized conditions outlined by Good Manufacturing Practice (GMP).
