Patient's question:
The stomach and intestines pills from my home were left open for half a month after opening the lid. I want to know, how long until they expire? And do they still have efficacy?Doctor's answer:
Hello, generally speaking, if a drug has been stored for too long, it may accumulate dampness, which can affect its efficacy. It is recommended not to take it, as the side effects may become more severe. It is best not to take medications for a long period. If it hasn't been opened for long and is not damp, it can be taken. Every drug has an expiration date. As long as it is stored properly within the valid period, it is usually safe to take orally. After opening the lid, avoid sunlight exposure as much as possible and store it in the refrigerator. The general validity period is two years, as long as it hasn't spoiled or become damp, it can be taken orally.
