How Long Does Amoxicillin Stay In Your System?

When you ingest any antibiotic, it takes your body quite some time to fully process them, leaving their traces for hours or even days.

Amoxicillin, one of the more common antibiotics, leaves the body relatively faster. After ingestion, the effects can be significantly diminished in as little as 5 to 7 hours.

In this article, I’ll endeavor to explain the working mechanics of amoxicillin, where and how it’s used, and what expected side effects there are.

I’ll explain how long it’s estimated to stay in the body, and how to best determine when it’s advisable to reach out to a professional.

What is Amoxicillin?

Amoxicillin is an antibiotic averaging 50 million prescriptions each year in the US. It is of the penicillin family because it connects an amino group to penicillin.

This modifies the antibiotic’s structure and provides some resistance to forming a bond with the same antibiotic.

Amoxicillin alters the growth and multiplication cycle of bacteria. Similar to most antibiotics, amoxicillin has no effect against virus infection.

 In cases of bacterial infection caused by a virus, such as bacterial pneumonia of the flu or cold virus, some healthcare professionals prescribe antibiotic.

 Those who are allergic to penicillin are generally severely allergic to amoxicillin. Inform the professionals of any side effects you experience from the medications you take.

How Long Does Amoxicillin Stay In Your System?

Most individuals have amoxicillin out of their system after about 12 hours. The length of time antibiotic stays in your system depends on the dose, as well as body weight, kidney function, other medications, and other health issues.

After a dose of antibiotic, it is quickly processed by the kidneys. After about an hour, half of the dose is processed. It takes 8 hours for this medicine to completely exit the blood stream. The rest of the amoxicillin is slowly removed by the kidneys after 8 hours.

Note: The length of time for a person to completely clear a medication will vary. Those with kidney issues and even newborns will take longer to clear antibiotic, which can be up to 3 days.

How Long Do You Have To Take Amoxicillin?

Courses of amoxicillin generally are 5-10 days, but can be for as long as 2 weeks. The length of time you take antibiotic depends on your infection and its severity.

 Even if you begin to feel better, it is important to finish the entire prescription. If you do not, bacteria that is resistant to antibiotic may survive and cause issues in the future.

Best Timing To Take Amoxicillin?

Amoxicillin is generally prescribed to be taken two to three times daily by most adults or children. Taking antibiotic with meals works best.

Amoxicillin does not need to be taken with food, however common symptoms of antibiotic are nausea, vomiting and diarrhea which can be worsened by an empty stomach. Taking antibiotic with food can lessen the risk of stomach related symptoms. Keeping up with meals is a good way to keep up with taking your medication.

Is It Necessary To Take Amoxicillin On Its Own?

Amoxicillin can be taken on its own but there are certain scenarios where co administration should be avoided.

If you are planning to take certain travel vaccines (live cholera vaccine (Vaxchora) or live typhoid (Vivotif) vaccine) along with antibiotic you need to keep some safe distances between the two.

 If taken together, antibiotic reduces the efficacy of these travel vaccines. For this reason, Vaxchora vaccine should be administered at least 14 days (2 weeks) after amoxicillin and Vivotif vaccine should be administered at least 72 hours (3 days) after antibiotic.

Along with the travel vaccines, there are other vaccine related drug interactions that need to be considered.

The antibiotic-warfarin interaction is a frequently observed one, and can cause excessive bleeding. Other examples of drugs with a similar interaction include allopurinol (Zyloprim) and probenecid.

Do These Antibiotics Compare?

Amoxicillin is a lot more convenient and prescribed over other penicillins by virtue of being more effective, cheaper and widely available but that does not make it better than other penicillin antibiotics. The best antibiotic for you is still dependent on the type and severity of the infection.

antibiotic is closely connected to penicillin antibiotics chemically. Because it takes out a variety of bacteria, it is classified as a broad spectrum antibiotic.

However, there are times when it may not be the right option. There are situations where using other penicillin antibiotics may be better than antibiotic.

This is because other penicillin antibiotics, like Augmentin and Zosyn (piperacillin/tazobactam), have different types of antibacterial activities than antibiotic.

Some penicillin antibiotics also have different modes of administration, like the IV administration of these drugs. Amoxicillin is only available as an oral formulation.

What Are The Symptoms Of An Amoxicillin Allergy?

Most people with an amoxicillin allergy (penicillin allergy) develop a rash that itches and is raised within the first hour after an antibiotic dose. There may also be swelling of the face, wheezing, and fast heart beat.

Allergic reactions to antibiotic can be confusing. In most cases, if you’ve had a mildly allergic reaction to penicillin, it is highly likely that you do not have a real allergy to penicillin (mistaken allergy). In other cases, an allergy may go away (resolved allergy).

If you had a reaction to antibiotic in the past, notify your healthcare provider. They can then perform a skin test to see if you have an allergy to penicillin antibiotics, like amoxicillin.

Is Amoxicillin Safe To Take?

Amoxicillin is generally safe to take. It’s well tolerated by most, but it is important to be aware of its side effects, like all medications. Thankfully, most side effects of antibiotic are mild and go away after you stop taking it.

Side effects of antibiotic include nausea, vomiting, diarrhea. It can cause skin rashes and change your taste or even your sense of smell, and it can cause headaches.

Starchy and plain foods are a good next step if you still get an upset stomach. If your stomach is still upset, your healthcare provider can recommend over-the-counter products for upset stomachs.

You should get in contact with your healthcare provider if you have not had an improvement after four days of vomiting or diarrhea. A large amount of fluids and electrolyte drinks are very important to stay hydrated.

Skin rashes are an issue for some. Most skin rashes get better on their own after a few days. However, if hives (raised, itchy bumps) show up, this can be a severe allergic reaction and you should stop taking antibiotic and contact your provider. If you have a worsening rash or begin to swell, contact your provider.

Bottom Line

For most people, antibiotic stays in your system for at least 12 hours. However, medical conditions can prolong this. How long you take antibioticis based on your medical condition and the severity of your infection. In most cases, taking amoxicillin is safe.

The side effects from amoxicillin should go away after you complete the treatment, and your healthcare provider should be notified of bothersome side effects.
