    Can Amoxicillin Clean You Urine For A Drug Test?

    Drug testing rumors spread like weeds (pun intended) on the internet, and one of the biggest rumors that you will see concern if that “X” drink (I.E. Cranberry Juice) will allow me to cheat a drug test or if I take X drug will I have a “false positive.”  Also, a dangerous rumor is that a  so-called “baking soda bomb” could help with urine tests.  Amoxicillin is an antibiotic that is one such drug that has many rumors concerning if this medicine can allow you to cheat a urine test.

    Amoxicillin, which is in the same class as penicillin, is used to treat bacterial infections by halting harmful bacteria growth.  For example, along with other medicines, It is commonly used for treating bacteria that cause gastrointestinal ulcers. It needs to be emphasized that it only can cure bacterial infections and not viral infections. As a result, antibiotics are useless when it comes to cold, flu, etc.

    It has been rumored that Amoxicillin can clear out your system for a UA test or taking it can result in a false positive drug screening test for cocaine.

    I will address these issues and more on this continuing series on drug tests. First of all, I will though examine the following:


    Can Amoxicillin and Other Antibiotics Cause False Positive For a Drug test?

    Are Antibiotics A Key For You Passing a Drug Test?

    A false positive occurs when you mistakenly test positive for illicit drugs on a drug test.   The results can be devastating and can result in you either being fired, not getting a job or in the case of a probation violation even being put in jail.


    This classic Seinfield episode made light of how poppy seed muffins could make you fail your test.

    The error can occur through lab error, certain medicines, or even food. For example, poppy seeds have been known to falsely indicate opiate use. As for medicines, SSRI drugs (drugs used for mental health conditions like depression, OCD, etc.) have been shown to bring about a false positive for LSD and meth.

    What About Amoxicillin?

    There has been a link in both medical journals and also in non-medical journals that imply that amoxicillin may result in you testing positive for cocaine. According to this article, published via Pub Med, this is false and Amoxicillin will not cause you to have a false positive for any illicit drug that tested by the lab.  However, to be safe I would tell the testing lab that you have been taking this medication.

    What Should You Do?

    Honesty is the best policy when it comes to dealing with a potential false positive on a urine drug test. So, be sure to tell the testing lab all of the prescribed medications that you are currently using. This means ALL medications and any vitamin supplements that you may be taking.

    What Are Potential Side Effects From Amoxicillin?

    Like pretty much all pharmaceuticals, amoxicillin does have a few side-effects. However, unless you are allergic to it, it is generally pretty safe to take. Some of the common side effects that it may cause are the following

    • Stomach Issues- Diarrhea, Upset Stomach, Etc.
    • Headache
    • Altered Sense of Taste
    • Ras
    • Yeast Infection-Mostly Vaginal.

    The less common side effects occur with those that are allergic to Amoxicillin, some of which are listed below:

    • Itching-Hives, Blisters,
    • Swelling- Face, Lips, and Tongue will often swell up
    • Dizziness
    • Weakness

    What Are The Dangers of Overdosing on Amoxicillin?

    Poison.Org states that there is not much that will happen if you overdose on Amoxicillin, and no treatment is likely necessary for an Amoxicillin or ANY antibiotic overdose. Per Poison.Org the likely worst thing that will happen is a tummy ache and dysentery. The only real-time you should have to go see a doctor is if you suffer an allergic reaction.

    Antibiotic Resistance

    As I stated earlier unless you suffer from an allergic reaction; overdosing from antibiotics will not result in anything that is life-threatening. However, using too many antibiotics can result in antibiotic resistance, which can be deadly.

    Antibiotic resistance happens when certain bacterial infections adapt and are able to fight off certain antibiotics. It is a serious problem. According to the CDC, at least 2.8 million people suffered bacterial infections that were resistant to modern-day antibiotics and an estimated 35,000 deaths have occurred in the US each from an antibiotic-resistant bacterial infection. Click Here for an article that shows examples of typical antibiotic-resistant bacteria.

    What Are The Main Causes of Antibiotic-Resistant Bacteria?

    Some of the most common reasons for this happening are the following:

    • Antibiotics being unnecessarily prescribed.
    •  Not finishing all of your pills that you were given in a prescription. This most often occurs when you stop taking them after your symptoms get better.
    • LiveStock and Fish-Too many antibiotics being used in raising livestock and also fish farming.
    • Poor Sanitation-
    • Few new antibiotics being discovered.

    In the short-run, too many antibiotics may not be outright deadly, in the long-run, it can kill you.

    Does Amoxicillin Clean Out Your System You For A Drug Test?

    Can taking Amoxicillin result in cheating a UA lab test? I did a thorough search for this question on the Internet and could not find any article (either scientific or lay) that addressed this question. Indecently, I know this is a common question because Googe lists a variant of this question on the “People Also Ask” section on this Google search term, and this query also occurred on the website Quora. I will now address, what I did find out concerning if Amoxicillin has any detox benefits and if it can help you cheat a urine drug test.

    Will It Help You Cheat Your Urine Test?

    As I stated, I could not find out any articles that directly addressed this question. The only articles that I did find related to how long amoxicillin will last in your body and whether or not it could result in a false test were from a Quora question. This question asked if Amoxicillin, for purposes of creating your urine test, could it mask or remove Cannabis from your body?

    It is doubtful that any Medical Doctor would want to be associated with giving patients advice on how to cheat a drug test. Therefore, lack of information on this subject does not necessarily indicate, one way or the other, that Amoxocilin will or will not help you pass a UA.

    The only answer that I saw for this question was from Quora. The person who answered the question was anonymous; therefore, I do not have any way to validate his or her credentials. So, for what it is worth they stated that Amoxicillin can only be used to treat infections and it WON’T detox your body or help you cheat a urine test.

    Final Thoughts

    It is a cat and mouse game between drug testing labs and the person being drug tested. You may luck out with a home remedy that will help you one time to pass a drug test. But, once the drug testing lab finds out what was done they will be able to detect that trick, which means that you will fail that test the next time if you try to use that trick.

    When it comes to Amoxicillin I was surprised at the lack of information concerning if it could help clear out your system. Drug testing is a billion-dollar industry (industry is projected to be worth around seven billion dollars by 2027). So, testing labs will always have the upper hand. Therefore, even though I could not find any information concerning if Amoxicillin can help with detox, I highly doubt that it will clean out weed in your system to help you cheat your drug test. Also, antibiotic drug resistance is a serious problem, and taking unnecessary antibiotics can cause you to be afflicted with this potentially deadly affliction.

    In conclusion, because of no scientific studies  (yeah or nay), concerning Amoxicillin detox abilities and the dangers of antibiotic resistance, you definitely should stay away from amoxicillin, penicillin, or any other antibiotics as a means to pass your drug test.


    Can amoxicillin clean your system from drugs?

    No, Amoxicillin is an antibiotic that is designed to fight off bacterial infections. It will not help you detox your system (body) or clean your system from drugs. Drug testing is a game of cat and mouse between the drug testing labs and the drug tested. Drug testing is a billion-dollar business. So, the drug testing labs will have the upper hand. Not moralizing, but the only tried and true method for passing a drug test is the passage of time.

    How long does it take for amoxicillin to clear your system?

    This is a trick question. It will take forever for amoxicillin to clean out your system because amoxicillin is not designed to detox your body or clear out illicit drugs from your body. The only sure way to pass a drug test is time passing.

    What bacteria does amoxicillin treat?

    Amoxicillin may not work for clearing out your system of drugs. But, it can be an effective antibiotic for killing bacterial infections. Per WebMD, it can treat the following bacterial infections:

    • Skin Infections
    • Tonsillitis and Strep Throat
    • Lyme Disease
    • Typhoid Fever
    • Peptic Ulcer Caused By The Bacteria Helicobacter Pylori
    • Many more.
