Fever reducing injections only have the effect of reducing fever, and have no necessary relationship with the relief of tummy ache. If you want to relieve stomach pain, you should find out the cause of the stomach pain, and treat the stomach pain to get better. If you need to take a fever-reducing injection, you should have fever symptoms, accompanied by stomach pain, which may be caused by acute gastroenteritis, or may be caused by other diseases such as mesenteric lymphadenitis. In the treatment of acute gastroenteritis and mesenteric lymphadenitis, if there is a bacterial infection, anti-infective treatment should be given, which can be treated with drugs such as amoxicillin, cefixime and levofloxacin. In addition, for patients with intestinal spasms that cause stomach pain, drugs such as scopolamine can be given to relieve the symptoms of stomach pain by relieving the intestinal spasms. The fever-reducing injections are usually compound aminobarbital and other drugs, which have only antipyretic effects, no anti-infective effects, and no effect of relieving intestinal spasms to relieve tummy pain. If you have fever and stomach pain, please consult a doctor for a clear diagnosis and treatment. The use of drugs must follow the doctor’s instructions, not blindly use their own drugs, so as not to cause adverse consequences.
