There are no obvious disadvantages for children taking splenomidine. Because splenamin is an immunomodulator, its main function is to regulate immunity, and it is a medicine that strengthens the system and the ability to fight diseases. It is suitable for children who are often sick because it can reduce the chance of colds, coughs, acute upper respiratory infections, diarrhea and other diseases. However, it should not be ingested in excessive amount at one time, nor should it be relied on splenamine-based medicine for a long time, otherwise it will cause the following side effects: 1. Allergic reaction: If splenamine-based lyophilized powder is a kind of one-way immunity regulator, if the oral dose is not right and the immunity regulation is too high, it will cause hyperimmunity, thus causing allergy, rash and other adverse reactions. And spleen aminopeptide oral solution is a two-way regulator, which is generally safer and has less side effects; 2. Obesity and liver damage: the main components of spleen aminopeptide lyophilized powder are nucleotides and peptides, which are extracted from animal spleen, and improper dosage will cause itchy skin, erythema and other uncomfortable symptoms, and may also lead to obesity, and serious cases will lead to stiff neck and aggravate liver damage. Children’s liver metabolism is relatively weak, it is recommended that each dose should not be too large, and should not be taken for a long time, it is easy to increase the burden of metabolism and excretion of the liver and kidneys.
