Is It Safe to Mix Amoxicillin and Alcohol?

Wondering if you can drink alcohol while taking the antibiotic amoxicillin? This question is commonly asked since amoxicillin is used to treat a wide variety of conditions. Learn more about this medication and its effects.

What Amoxicillin Treats

Amoxicillin is a common antibiotic medication used to treat bacterial infections. It will not treat colds, the flu, or infections caused by viruses. It is used to treat bacteria that are beta-lactamase–negative, including for \[1\]:

• Ear, nose, and throat infections
• Eradication of Helicobacter pylori, a common stomach infection
• Lower respiratory infections
• Urinary tract infections
• Acute bacterial sinus infection
• Skin infections including rash

How Amoxicillin and Clavulanic Acid Work Together

Amoxicillin is a penicillin antibacterial that belongs to the class of beta-lactam antimicrobials. Beta-lactams bind to penicillin-binding proteins, inhibiting a crucial step in cell wall synthesis. This action activates certain enzymes in the bacterial cell wall, resulting in cell wall breakdown and therefore, bacterial cell destruction. This is known as bactericidal killing.

Clavulanic acid can be used with amoxicillin to manage and treat bacterial infections, specifically those that are beta-lactamase producers. It is in the beta-lactamase inhibitor class of medications \[2\].

If a bacterial strain is beta-lactamase-negative and susceptible to beta-lactam antibiotics, these antibiotics can be used effectively. Amoxicillin can be combined with a beta-lactamase inhibitor, such as clavulanic acid. These inhibitors function by irreversibly binding to the organism’s beta-lactamase enzyme, preventing resistance to the original beta-lactam ring of amoxicillin.

Amoxicillin Interactions: Risks and Side Effects

Amoxicillin is generally a safe, well-tolerated drug that is widely used. Amoxicillin may lead to common gastrointestinal symptoms, including nausea, vomiting, and diarrhea. Additionally, side effects may include \[3\]:

• Allergic reactions—rash, itching, hives, swelling of the facial area
• Redness, blistering, peeling, or loosening of the skin, including inside the mouth
• Severe diarrhea, fever
• Severe or prolonged vomiting or diarrhea
• Unusual vaginal discharge, itching, or odor

Unlike some other antibiotics, it is safe to drink alcohol with Amoxicillin. However, it is recommended to avoid drinking in excess while you’re taking it. Amoxicillin can cause other potential complications, including gastrointestinal issues, and alcohol can worsen these \[4\].

Safety Measures: When Is It Safe to Drink Again?

If you’re wondering how long antibiotics stay in the system, Amoxicillin has an approximate half-life of 61.3 minutes, and about 60% of the administered dose is excreted in the urine within 6 to 8 hours. If you miss a dose, just take the next one at the correct time.

What to Do If I Can’t Stop Drinking?

In general there should be little to no interaction with Amoxicillin if you continue drinking, subject to the side effects referenced above.
