Is the expiration date for a drug the first or last day of the month?

If the drug expiry date is mentioned as a month, it generally means that the drug is good for an entire month or you can say the actual expiry date is the last day of the month. This is quite commonly seen on medications and people often get confused. 

The reason why they mention the month instead of the date is to ensure the buyers that the med is under the manufacturer’s guarantee till a certain month. 

After that month has passed, the manufacturer does not guarantee the safety and efficacy of the medication. Now, drug expiry is not what you may think it is. Drugs don’t necessarily go bad right away. 

Let’s say your drug expires on 10th October, but that doesn’t mean that your drug will turn into poison on 11th October. Drug degradation can take a long time, but it can begin earlier as well, depending on the storage condition. 

The entire concept of expiry date is to know that the manufacturer does not guarantee that the med will work once it’s past the expiration date. It could work, many do, but many don’t. 

Is it okay to use expired medications?

It is not generally recommended by the Food and Drug Administration (FDA) to use expired medications (1). The use of expired meds can be even more tricky for people with chronic illnesses or those having an active infection in their bodies. 

This is because expired medications begin to lose their efficacy with time and they don’t work the way they should. This can result in therapeutic failure and you will not find your condition getting any better.

However, some medications like Tetracycline antibiotics can chemically convert into toxic substances once they are past the expiration dates. This can trigger a severe allergic reaction in some people or may cause other disturbing side effects. 

Some life-saving medications, like Epinephrine, should also not be used after they expire because of therapeutic inefficacy and potential worsening of the condition. 

People with blood disorders should also not use expired medications, like Warfarin, as the drug won’t help their symptoms and can put some people at life-threatening health risks. 

Similarly, antidepressants begin to lose potency as they expire, which can affect your treatment and your mental health. This is why it’s best for you to avoid using expired medications and replace them with new ones. It’s not worth risking your health. 

What to do if you have accidentally taken an expired medication?

If you have accidentally taken a dose or two, don’t worry. A single dose is not likely to hurt you or put your health at risk. However, people are different and they may respond differently to medications. 

If you feel unusual after taking expired medication, immediately call your local medical emergency helpline. To prevent accidental administration of expired medications, make sure you properly discard them.
