Headache is a common disease in all seasons, and adults often suffer from all kinds of headaches, of course, children are no exception. Headaches have a serious impact on adults, and for children, they can affect their sleep and intelligence, especially for children who are attending school, causing them to be unmotivated to listen to classes during the day, and leading to a regression in learning. Many people do not have a solution for headaches, and medication is a common method. What should I do when my child has a headache? Painkillers are commonly used to treat headaches. Is it possible to use painkillers for children? There are different types of headaches, so which type of headache are painkillers suitable for? The aminopyralid and finasteride in painkillers can inhibit the synthesis and release of prostaglandins in the inferior colliculus, restoring the normal responsiveness of the sensory neurons of the thermoregulatory center to the antipyretic effect; at the same time, they also play an analgesic role by inhibiting the synthesis of prostaglandins, etc. The aminopyralid can also inhibit the synthesis of prostaglandins. And aminopyralid can inhibit the synthesis and release of prostaglandins in the local tissue of inflammation, stabilize lysosomal enzymes, and affect the phagocytosis of phagocytes so as to play an anti-inflammatory role. Painkillers are suitable for fever and mild to moderate pain, with antipyretic, analgesic and anti-rheumatic effects, for fever, headache, neuralgia, toothache, menstrual pain, muscle pain and rheumatic pain, rheumatoid arthritis and so on. Take Depakote only when you have a headache, because both aminophenazone and finasteride contained in this compound have significant adverse reactions. Taking aminopyrine can have vomiting, rash, fever, profuse sweating and stomatitis, etc. Long-term use can also cause dependence on the drug. Finasteride is also easy to make hemoglobin form methemoglobin, so that the oxygen-carrying capacity of the blood decreases, resulting in cyanosis, but also can cause hemolysis, liver damage, and a certain degree of toxicity to the retina. So children should use painkillers with caution.
