## How to consider the expiration date The shelf life of any medication — from vitamins to injections, ointments, or pills — depends on how complex substances are included in their composition. It also depends on how stable the active substance molecule itself is in the form in which it is produced. All of this is determined in the production process through in-depth research. If a molecule is just being developed, it necessarily undergoes strict clinical trials. All chemical synthesis is naturally tested in the plants themselves. During storage, the efficacy is monitored for duration and performance. ## Considerations The shelf life of drugs is a fundamental indicator. Thus, in the case of prescription and individual nonprescription drugs, it is important not only to strictly monitor the "deadline" but also to store them strictly at the temperature specified in the instructions and protect them from sunlight. If this is not done, ===some of the constituent substances may change and the drug will cease to be effective. The same will happen with almost any expired gels and ointments. You should not use them if their appearance has changed. Although using expired medications may not poison you, it is still best to be safe. ## Save carefully Medications related to cardiological, neurological, gastrointestinal issues should not be taken past the expiration date. This is especially true if the medication is part of a course of multiple medications or treatment. ## Don’t risk it There is a relative reserve of time to take supplements and vitamins. The former can "work" for another two months after the expiration date. The latter, when expired, will not harm, but they will have lost their effectiveness. Despite this, doctors and pharmacists recommend using all supplements, vitamins, and medications before the expiration date.
