If you have been prescribed an antibiotic, you may be wondering how long does augmentin stay in your system.

Augmentin is an antibiotic that is used to treat a variety of bacterial infections, such as pneumonia, ear infections, sinus infections, skin infections, and urinary tract infections.

The duration of time that Augmentin stays in your system can vary depending on several factors.

One of the factors that can affect how long Augmentin stays in your system is the dosage.

The higher the dose, the longer it may take for the drug to be eliminated from your body.

Another factor that can impact the duration of Augmentin in your system is how the medication is taken.

Augmentin is available in both tablet and liquid suspension form, and the liquid suspension may take longer to be cleared from your system.

How Long Does Augmentin Stay In Your System?

If you are taking Augmentin, you may wonder how long it stays in your system.

The answer depends on several factors, including your age, kidney function, dosage, and duration of treatment.


As you age, your body’s ability to process medications may slow down.

This means that Augmentin may stay in your system longer if you are older.

However, there is no specific age at which you should be concerned about the length of time Augmentin stays in your system.

Kidney Function

Your kidneys play a crucial role in eliminating medications from your body.

If your kidneys are not functioning properly, Augmentin may stay in your system longer than usual.

Your doctor may need to adjust your dosage or monitor your kidney function if you have kidney problems.

Dosage and Duration

The dosage and duration of your Augmentin treatment can also affect how long it stays in your system.

Higher doses and longer treatment durations may result in Augmentin staying in your system for a longer period of time.

According to HealthTap, Augmentin does not stay in the body for more than 24-48 hours.

However, this can vary depending on individual factors such as age, kidney function, and dosage.

It is important to follow your doctor’s instructions regarding dosage and duration of treatment to ensure that Augmentin is effective and does not stay in your system longer than necessary.

Overall, it is important to talk to your doctor if you have any concerns about how long Augmentin stays in your system.

Your doctor can provide personalized advice based on your individual health status and treatment plan.

Pharmacokinetics of Augmentin

Absorption and Distribution

Augmentin is a combination of two drugs, amoxicillin, and clavulanic acid.

After oral administration, both drugs are rapidly absorbed from the gastrointestinal tract.

The absorption of amoxicillin is not affected by food, while clavulanic acid absorption is reduced by approximately 30% when taken with food.

The distribution of amoxicillin and clavulanic acid in the body is similar.

They are both widely distributed in the body tissues and fluids, including the lungs, middle ear, and sinuses.

The concentration of both drugs in the cerebrospinal fluid is low, but they can penetrate the placenta and breast milk.


Augmentin is not metabolized in the body. Amoxicillin and clavulanic acid are both excreted unchanged in the urine.


The elimination half-life of amoxicillin is about 1.3 hours, while that of clavulanic acid is about 1 hour.

Approximately 50% to 70% of the amoxicillin and approximately 25% to 40% of the clavulanic acid are excreted unchanged in the urine within the first 6 hours after administration.

In patients with renal impairment, the elimination half-life of both drugs is prolonged, and the dose of Augmentin may need to be adjusted accordingly.

Overall, Augmentin is a well-tolerated antibiotic with a short half-life. It is rapidly absorbed and distributed in the body tissues and fluids, and it is excreted unchanged in the urine.

However, it is important to follow the prescribed dosage and duration of therapy to ensure the effectiveness of treatment and to minimize the risk of adverse effects.

Detectable Times in Body Fluids

Blood Plasma

Augmentin is rapidly absorbed into the bloodstream after oral administration.

Peak concentrations are usually seen within 1.5 hours of a dose of Augmentin.

The half-life of Augmentin is about 1 to 1.5 hours in healthy adults. However, it may take up to 48 hours of dosing for a clinical improvement to be seen.


Augmentin gets cleared from the body rapidly, within hours.

Most pharmacy books list a half-life of 1 to 1.5 hours.

This assumes regular kidney function, or at least close to normal.

Trace amounts of Augmentin may be detected in urine for a few days, but not enough for antibiotic effects anymore.

It’s important to note that detectable times in body fluids may vary depending on several factors, such as age, weight, liver, and kidney function.

Typically, it takes around 24-48 hours for Augmentin to completely leave your body.

However, if you have impaired liver or kidney function, it may take longer for the medication to be eliminated from your system.

If you have any concerns about how long Augmentin stays in your system, you should consult your healthcare provider.

They can provide you with more specific information about how long the medication will remain in your system based on your individual health status.

Safety and Side Effects

When taking any medication, it is important to be aware of the potential risks and side effects.

Augmentin is no exception. Here are some things to keep in mind:

  • Allergic reactions: Some people may be allergic to Augmentin.
    • Signs of an allergic reaction include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat.
    • If you experience any of these symptoms, seek medical attention immediately.
  • Gastrointestinal issues: Augmentin can cause digestive problems such as nausea, vomiting, stomach pain, and diarrhea.
    • These symptoms are usually mild and go away on their own, but if they persist or become severe, talk to your doctor.
  • Yeast infections: Augmentin can disrupt the natural balance of bacteria in your body, which can lead to a yeast infection.
    • Symptoms of a yeast infection include itching, burning, and discharge. If you experience these symptoms, talk to your doctor.
  • Liver damage: In rare cases, Augmentin can cause liver damage.
    • Symptoms of liver damage include yellowing of the skin or eyes, dark urine, and abdominal pain.

If you experience any of these symptoms, stop taking Augmentin and seek medical attention immediately.

It is important to take Augmentin exactly as prescribed by your doctor.

Do not stop taking the medication early, even if you start to feel better.

If you have any concerns about the safety of Augmentin or its side effects, talk to your doctor.

They will be able to provide you with more information and guidance.
