can you take expired antibiotics | Important Points

The issue of taking expired antibiotics has been a subject of controversy in the medical community. While some believe that taking expired antibiotics poses no risk to health, others say that it can lead to serious complications. In this article, we’ll delve deeper into the subject and explore whether you can take expired antibiotics.

What Are Antibiotics?

Antibiotics are medications that destroy or slow down the growth of bacteria. They are prescribed to treat bacterial infections such as pneumonia, strep throat, urinary tract infections, and skin infections. Antibiotics work by disrupting the cell wall or cell membrane of the bacteria, which either kills the bacteria or stops it from multiplying.

Types of Antibiotics

There are different types of antibiotics, and they work differently to treat bacterial infections. Some common types of antibiotics include:

1. Penicillins: These include drugs such as amoxicillin, penicillin, and ampicillin.

2. Cephalosporins: These include drugs such as ceftriaxone, cephalexin, and cefuroxime.

3. Fluoroquinolones: These include drugs such as ciprofloxacin and levofloxacin.

4. Macrolides: These include drugs such as erythromycin, clarithromycin, and azithromycin.

5. Tetracyclines: These include drugs such as doxycycline, tetracycline, and minocycline.

What Happens When Antibiotics Expire?

Like all medications, antibiotics have a shelf life. This means that after a certain period of time, the drug may no longer be effective or safe to use. The expiration date is usually printed on the medication label and indicates the date after which the medication may start to deteriorate.

When antibiotics expire, they can no longer guarantee the same level of potency as when they were originally manufactured. This is because over time, the chemical structure of the drug breaks down, making it less effective. This means that the drug may not kill all the bacteria causing the infection, which can lead to the development of antibiotic-resistant bacteria.

Can You Take Expired Antibiotics?

The short answer is no. It is not recommended to take expired antibiotics, even if they have been stored properly. This is because the expired drugs may no longer be effective in treating the bacterial infection, which can lead to the development of antibiotic-resistant bacteria.

Still, some people argue that taking expired antibiotics is better than not taking any medication at all. They believe that the drug may still be effective, although not at the same level of potency as when it was fresh. However, this is not a risk that is advised.

Additionally, taking expired antibiotics can cause other health problems. Some of these problems include:

1. Gastrointestinal Issues: Expired antibiotics can cause nausea, vomiting, diarrhea, and stomach cramps.

2. Allergic Reactions: Taking expired antibiotics can lead to an allergic reaction, which can cause skin rashes, hives, and difficulty breathing.

3. Kidney Damage: Expired antibiotics can cause kidney damage, which can lead to kidney failure.

4. Liver Damage: Taking expired antibiotics can also cause liver damage, which can lead to liver failure.

What Happens When You Take Antibiotics Incorrectly?

Taking antibiotics properly is crucial for their effectiveness. Incorrect usage can cause several problems, including:

1. Antibiotic Resistance: When antibiotics are not taken correctly or prescribed unnecessarily, bacteria can develop resistance to them. This means that the bacterial infections will no longer respond to the drugs that were once effective.

2. Superinfections: Taking antibiotics incorrectly can also lead to the development of secondary infections such as yeast infections or Clostridium difficile infection.

3. Allergic Reactions: Some people may be allergic to certain types of antibiotics. Taking the wrong antibiotic can cause a severe allergic reaction, which can lead to anaphylaxis.

How to Store Antibiotics Properly

To ensure that antibiotics remain effective, it is essential to store them correctly. Here are some tips for storing antibiotics:

1. Keep them in a cool, dry place: Antibiotics must be stored in a cool, dry place away from sunlight. Exposure to heat and humidity can cause the drugs to deteriorate.

2. Keep them in their original packaging: Antibiotics must be kept in their original packaging to protect them from light, moisture, and heat.

3. Don’t store them in the bathroom: The bathroom is not the best place to store antibiotics as it can get humid and warm, which can cause the drugs to deteriorate.

4. Don’t leave them in the car: It is best not to leave antibiotics in the car, especially in hot weather, as it can cause the drugs to deteriorate quickly.


In conclusion, taking expired antibiotics is not recommended. Antibiotics should be taken as prescribed by a healthcare professional and stored correctly to ensure their maximum potency and effectiveness. Correct usage can help to prevent the development of antibiotic-resistant bacteria, secondary infections, and allergic reactions. If you have expired antibiotics, it is best to dispose of them safely and consult with your healthcare provider about the best course of action for your bacterial infection.
