Adverse effects of Analgin
Disease description:
I often hear about a medication called Analgin (Metamizole) in fever-reducing drugs, but generally doctors do not recommend its use. I would like to ask physicians about the side effects of Analgin.
Doctor's answer (1)
Dr. Shen Yonghua
Analgin, composed of aminopyrine and phenacetin, is an antipyretic and analgesic medication commonly used to relieve mild to moderate pain and reduce fever. However, it also has some side effects, including:
1. Gastrointestinal reactions: May cause nausea, vomiting, abdominal pain, or gastric ulcers, especially with long-term or high-dose use.
2. Effects on the blood system: May cause agranulocytosis, a condition characterized by a reduced number of white blood cells, increasing the risk of infection.
3. Allergic reactions: Some individuals may be allergic to components of Analgin, presenting as rash, urticaria, or, in severe cases, anaphylactic shock.
4. Liver damage: Long-term use may cause liver injury, leading to abnormal liver function.
5. Kidney damage: In rare cases, it may affect kidney function, especially in patients with pre-existing kidney disease.
6. Arrhythmias: High doses or overdose may lead to cardiac problems such as irregular heartbeat.
