Expiration dates are important to know about because we always think that any medicine way passed their expiration dates aren’t that effective anymore and there are times that they can be poisonous. And so in this article, we will tackle about the shelf life of amoxicillin capsules and other drugs as well as the truth about it.
Normally, most medicines have the shelf life of about 1 to 2 years and the same applies to amoxicillin. Its shelf life mostly depends on the nature of the ingredients used in the medicine and other factors such as exposure to light, the temperature, moisture etc. The exposure of light might slightly increase the temperature and may affect some of the ingredients such as chemical reactions that may change the nature of the drug. So it’s recommended to store your medicines in a cool and dry place like inside your fridge to make them remain potent for a long period of time.
The truth is most medicines can still be good even after a decade. It’s because the government requires every manufacturer to submit a somewhat like an informative report to them mainly concerned about the drug. The shelf life of the drug is then based on the report submitted by the manufacturer. Most manufacturers may also prefer a 2 year shelf life most because it gives a reasonable scope for a cycle called production-distribution-consumption .There are drugs that may be still good even after years after the expiration date but its potency may drop for about 10 percent. There are also drugs such as phenobarbital, dilantin(drug for epileptic patients), lidocaine (anesthetic) and theophylline(asthma drug) that loses its potency even before their expiration dates. There are also instances when your medicine might change its color before the expiration date. In this case, you have to dispose properly the medicine because there’s a great possibility that it might be toxic already.
You might also ask why most pharmacists set a one-year expiration date to their prescribed medicines. It is so because generally the drug has undergone different situations upon released during the manufacturing process. Time may have lapsed already and potency of the drug might be affected if pharmacists won’t put the minimum expiration dates onto the product.
Generally speaking, most OTCs (over-the-counter drugs) such as amoxicillin have a long shelf life if you’ll store in properly. Though there are times that it may not be as effective as the drug before it expired, it is still good and still safe.
