What is ampicillin?
Ampicillin is an antibiotic in the penicillin class. It’s used to treat a variety of infections, including respiratory infections, urinary tract infections, gastrointestinal infections, meningitis, and certain bloodstream infections. Ampicillin can be given by mouth or injection, depending on the type and severity of the infection.
How does ampicillin work?
Ampicillin works by blocking the bacteria’s ability to build a strong cell wall. Without a proper cell wall, the bacteria weaken, burst, and die.
This makes ampicillin a bactericidal antibiotic, meaning it kills bacteria directly rather than just stopping them from growing.
How do I know if I qualify for ampicillin?
You may qualify for ampicillin if you have a bacterial infection it can treat, aren’t allergic to penicillin, and your doctor confirms it’s safe with your other health conditions and medications.
It’s often prescribed for respiratory, urinary tract, gastrointestinal, or serious systemic infections.

Frequently
Asked
Questions
How do I know if ampicillin is right for me?
Ampicillin is right for you if you have a serious bacterial infection it treats, aren’t allergic to penicillin, and your doctor confirms it’s safe with your health conditions and other medications.
Is ampicillin penicillin?
Yes, ampicillin is a penicillin-type antibiotic. It belongs to the beta-lactam class.
How long does it take ampicillin to work?
Ampicillin usually starts working soon after the first dose, but noticeable improvement in symptoms often takes one to three days, depending on the infection’s severity. It’s important to finish the full course to fully clear the infection.
Can you take ampicillin while pregnant?
Ampicillin is generally considered safe to use during pregnancy when prescribed by a doctor. It’s a penicillin-type antibiotic, and penicillins have a long history of use in pregnancy without known major risks.
Your doctor will weigh the benefits against any potential risks before prescribing it.
Can you drink while taking ampicillin?
There’s no direct interaction between ampicillin and alcohol, so moderate drinking usually doesn’t reduce its effectiveness. However, alcohol can increase side effects like stomach upset or dizziness, so it’s often recommended to limit or avoid alcohol while on any antibiotic.
Does ampicillin cause liver damage?
Ampicillin rarely affects the liver, but in some cases it can cause mild, temporary liver enzyme elevations. Serious liver damage is very uncommon. Doctors may monitor liver function if treatment is prolonged or if you already have liver problems.
What are the most common side effects of ampicillin?
The most common side effects of ampicillin include nausea, vomiting, diarrhea, and rash. Some people may also experience allergic reactions, which can range from mild skin rashes to, rarely, severe reactions like anaphylaxis.
