Can Niuhuang Jiedu Tablets still be taken after expiration?
Under normal circumstances, Niuhuang Jiedu Tablets should not be taken after expiration. The detailed explanation is as follows:

After a drug expires, its active ingredients gradually break down over time, leading to reduced efficacy or complete loss of effectiveness, which may fail to achieve the intended therapeutic effect and could delay treatment. Meanwhile, the chemical stability of expired medications decreases, potentially producing unknown degradation products. These substances have no therapeutic benefit and may instead irritate the gastrointestinal tract, causing discomfort such as nausea, vomiting, and abdominal pain. In severe cases, they may place additional strain on vital organs like the liver and kidneys, posing health risks. Therefore, expired medication should not be consumed.
Niuhuang Jiedu Tablets should be stored in a cool, dry place in daily use, away from direct sunlight and moisture to prevent premature deterioration. Always check the expiration date before taking the medication; if expired, dispose of it immediately and do not give it to others or continue using it. If you experience any health issues requiring medication, purchase a new supply that is within its expiration period and follow the instructions in the package insert or professional medical advice strictly to ensure safe use.
