Headache tablets are relatively common drugs in clinical practice and have been used for many years. Headache tablets are mainly applied to relieve the symptoms of cold and flu, as well as fever and headache caused by upper respiratory tract infection, and can also be used to treat neuralgia, rheumatic pain and toothache. The main ingredients are aminopyrine and caffeine tablets, which can relieve fever and analgesia and are mainly suitable for symptoms of fever caused by upper respiratory tract infection leading to headache. However, it is not recommended to take headache tablets often when you have a headache, because it is a salicylic acid preparation, and long-term use can cause damage to the gastrointestinal tract and lead to gastric mucosal erosion. There is also a risk of acute renal insufficiency and damage to the liver, resulting in hepatitis and jaundice. It is important to identify the cause of the headache and to actively treat it.
