Regarding babies
Toddlers and babies are often more affected by side effects than adults. There are several reasons for this. Firstly, the mass of a baby is usually smaller, so that the active substance can be taken in a higher concentration.
In addition, the composition of an adult body differs from that of a baby. For example, because active ingredients accumulate or distribute themselves differently in fatty tissue, this can affect the effect on a baby. Moreover, the blood–brain barrier in babies is probably not yet fully developed.
Therefore, drugs that cannot act in the central nervous system in adults can cross the protective blood–brain barrier in babies and thus have undesirable effects. Also with the income of Fenistil? drops with young children of a strong sedative (reassuring) effect is frequently reported, since the contained Dimetinden in the central nervous system has a sleep making effect. Children under the age of one are generally not advised to take Fenistil® drops.
Side effects in babies and toddlers
The side effects mentioned above can of course also occur in babies or infants after administration. In children, due to the lower mass and other differences to adults, stronger side effects may occur. Children under one year of age should not take Fenistil® drops or only in an emergency and then after consultation with a pediatrician.
Also the mother should refrain from taking Fenistil® drops while breastfeeding. In children over one year of age, care should be taken to ensure that the dose is reduced sufficiently. Erectile states have also been observed in children after taking antihistamines such as Fenistil® drops.
Interactions
Certain drugs may interact with Fenistil® drops when taken at the same time. This can be seen in undesirable effects or a change in the effectiveness of the substances taken. In general, the use of several drugs and Fenistil® drops should always be discussed with a doctor.
Special care should be taken when taking a tricyclic antidepressant and Fenistil® drops at the same time. Both are characterized by a so-called anticholinergic effect. In patients at risk of glaucoma attacks, which can lead to blindness if left untreated.
Other drugs for which interactions are warned are drugs used against epilepsy, certain sleeping pills, anxiety-relieving drugs and other antihistamines. The cytostatic drug procarbazine or strong painkillers, so-called opioid analgesics, can also interact with Fenistil® drops. The same applies to drugs for stomach or abdominal cramps, which also have an anticholinergic effect. Further interactions can occur when Fenistil® drops and drugs for vomiting or nausea, so-called antiemetics, are taken simultaneously. Because of the large number of possible interactions, the use of Fenistil® drops should always be discussed with a doctor or pharmacist.In addition, there are several databases for interactions on the Internet, which can be freely viewed.
