can you take antibiotics while drinking | Important Points

Antibiotics are prescribed by medical professionals to treat bacterial infections, such as strep throat, urinary tract infections (UTIs), and pneumonia, among other illnesses. However, while antibiotics can be effective in treating bacterial infections, some people wonder whether it is safe to consume alcohol while taking antibiotics.

Alcohol and Antibiotics: What’s the Connection?

The first thing that people need to understand is that there are different types of antibiotics, and each one works differently. Some antibiotics have different effects than others, and therefore, there is no one-size-fits-all answer to the question of whether it is safe to drink alcohol while taking antibiotics.

For example, some antibiotics can be affected by alcohol. Alcohol can increase the rate at which some antibiotics are metabolized by the liver, leading to lower antibiotic concentrations in the blood. As a result, antibiotics may become less effective when alcohol is consumed alongside them.

On the other hand, alcohol can have no effect on other antibiotics. Some antibiotics, like azithromycin (Zithromax), do not interact with alcohol, and therefore, you can consume alcohol while taking these medications.

Here are the most commonly prescribed antibiotics and how they interact with alcohol:

– Amoxicillin: There is no known interaction between amoxicillin and alcohol. However, alcohol can weaken your immune system, which can slow down the healing process.
– Azithromycin: There is no known interaction between azithromycin and alcohol. However, alcohol can weaken your immune system, which can slow down the healing process.
– Ciprofloxacin: Ciprofloxacin can interact with alcohol, causing uncomfortable side effects like nausea, vomiting, and headache.
– Metronidazole: Metronidazole should not be consumed with alcohol. Alcohol can cause an interaction that leads to severe nausea, vomiting, and abdominal pain.
– Doxycycline: There doesn’t seem to be any significant interaction between doxycycline and alcohol. However, it’s best to avoid alcohol when taking antibiotics.

What Happens When You Drink Alcohol While on Antibiotics?

Drinking alcohol while taking antibiotics can lead to unpleasant side effects. Below are some of the side effects that you may experience when you combine alcohol with antibiotics:

1. Reducing the effectiveness of antibiotics

Alcohol consumption can reduce the effectiveness of antibiotics, leading to the growth of antibiotic-resistant bacteria. Over time, this can cause some strains of bacteria to become resistant to antibiotics completely. When the antibiotics become ineffective, the bacterial infection may persist and worsen.

2. Slowing down the healing process

Drinking alcohol can impair your immune system, which may slow down the healing process. Given that antibiotics are used to treat infections, you may not be able to heal entirely while consuming alcohol.

3. Increasing side effects

Alcohol consumption can increase the side effects of antibiotics. For example, taking Ciprofloxacin and consuming alcohol can lead to nausea, vomiting, and headache.

4. Causing liver damage: When alcohol and certain antibiotics are consumed together, it can cause severe liver damage. As the liver is responsible for metabolizing both the alcohol and the antibiotics, consuming both at the same time can overwork the organ, leading to liver damage.

Should You Avoid Alcohol While Taking Antibiotics?

Medical professionals usually recommend that patients avoid alcohol while taking antibiotics to avoid unwanted side effects. While not all antibiotics interact negatively with alcohol, it is better to err on the side of caution. Alcohol can weaken your immune system, making it harder for antibiotics to fight the infection effectively.

Moreover, it is worth noting that alcohol can still be consumed in moderation even though you are taking antibiotics; however, it is your doctor’s call to make. Your doctor may recommend complete abstinence from alcohol while taking a specific antibiotic, while other doctors may tell you that one or two drinks won’t affect the medication’s effectiveness.

When to Avoid Alcohol While Taking Antibiotics

If you are taking antibiotics for a bacterial infection, it’s best to avoid alcohol until you complete the course of antibiotics. Here are some antibiotics that you should avoid drinking alcohol with:

1. Metronidazole: Zinc is contained in alcohol, which has been known to cause severe side effects when taken with Metronidazole. Consumption of alcohol with Metronidazole could lead to a severe reaction which could cause nausea, dizziness, and headaches.

2. Flagyl: This medication is a type of metronidazole oral, and it could lead to severe side effects like hot flashes, abdominal cramps, and sweating when consumed alongside alcohol.

3. Tinidazole: This medication is typically prescribed for the treatment of various bacterial infections such as giardiasis, trichomoniasis, and amebiasis. It could lead to severe side effects like vomiting, facial redness, and difficulty breathing when taken with alcohol.

Are There Any Alternatives to Antibiotics?

There are some natural alternatives to antibiotics that may help treat bacterial infections. These include:

1. Garlic: Garlic is a natural antibiotic – it has powerful antimicrobial properties and can kill harmful bacteria and viruses.

2. Probiotics: Probiotics are living bacteria that are beneficial to your health. By introducing good bacteria into your gut, you can help your body fight off harmful bacteria.

3. Vitamin C: Vitamin C can boost your immune system, making it more effective at fighting bacterial infections.

4. Echinacea: This plant extract is believed to have antibacterial and antiviral properties, and some research suggests that it may be effective at fighting bacterial infections.


In conclusion, the interaction between antibiotics and alcohol is complex, and it depends on the type of antibiotic you are taking. While some antibiotics interact negatively with alcohol, others do not. If you are taking antibiotics for a bacterial infection, you should avoid alcohol until you complete the course of antibiotics. Always consult with your doctor to ensure you are taking the correct medication and to understand the implications of consuming alcohol if taking antibiotics. And if you have been prescribed medication, it’s important to take the full course of antibiotics as prescribed, even if you start feeling better.
