Two months after the expiration date of antipyretic drugs can not be eaten. Two months after the expiration date of antipyretic drugs, if taken orally, not only can not play a role in curing the disease, but also bring a lot of adverse reactions. Patients may experience nausea, vomiting, abdominal pain, diarrhea and other gastrointestinal symptoms, or even gastrointestinal bleeding and anti-inflammatory ulcers, and some patients may also experience dizziness, headache, tinnitus or central nervous system symptoms such as vision loss. Some patients can develop liver and kidney function damage after taking antipyretic drugs, so antipyretic drugs should not be taken two months after the expiration date, and must be taken within the shelf life of antipyretic drugs.
