Effects of Amoxicillin

The effects of amoxicillin vary in intensity from mild to serious. Amoxicillin is a member of the penicillin family. Amoxicillin is a common antibiotic that is used to treat a variety of bacterial infections occurring with skin, ear, sinus, and upper respiratory system. While many people can take amoxicillin with no problems, some people are allergic to amoxicillin and experience adverse effects.

  1. Mild Side Effects

    • Some people have very mild symptoms, but other people experience symptoms that require immediate medical attention. Common side effects of amoxicillin are the following: mild diarrhea, sore mouth, or white patches in the mouth, headache, and vaginal itching and discharge.

    More Serious

    • The more serious effects from taking amoxicillin are the following: dark urine, yellowing of the skin or eyes, nausea and vomiting, stomach and abdominal pain, easy bruising, or bleeding, and persistent sore throat or fever--all mean you should call your doctor.

    Severe Stomach Condition

    • A severe intestinal condition may occur. Due to the resistant bacteria, a condition known as pseudmembranous colitis can take place several weeks after stopping the amoxicillin treatment. Contact a doctor as soon as possible when persistent diarrhea, stomach and abdominal pain, cramping, and bloody mucous in the stool occur. Do not use antidiarrhea products, or narcotic pain relievers, because these medications may make the symptoms worse.


    • Oral thrush or a new vaginal or yeast infection may also occur. Thrush is the appearance of white patches in the mouth, and can develop after taking amoxicillin for a long time. Contact your doctor.

    Allergic Effects

    • Some people are allergic to amoxicillin due to it being a member of the penicillin family. A person may react like a harmful substance has entered the body, rather than a medication coming to the rescue. The immune system will create antibodies to attack the medication. That will set up a person for an entire host of allergic reactions such as nausea, vomiting, a rash, itching, swelling, and sometimes dizziness. Some amoxicillin users may also experience difficulty breathing due to the allergic reaction.

    Other Effects

    • Amoxicillin can have other effects as well. Amoxicillin may actually decrease the effectiveness of birth control pills. Another form of effective birth control should be used while taking amoxicillin just to be on the safe side. Amoxicillin may cause a false/positive result with certain diabetic urine testing products. Amoxicillin can also affect the results of laboratory tests. A person would have to notify the doctor while taking amoxicillin and before lab tests are done.


    • It is a good idea to tell the doctor if you have allergies to penicillin or amoxicillin. Tell the health care professional if you are taking any other medication. An adverse reaction can be avoided. Tell the doctor if you have a kidney disease or infections such as mononucleosis.
