    Amoxil (Amoxicillin) Dosage and Side Effects

    AMOXIL is a drug used to treat bacterial infections.  Your doctor may prescribe AMOXIL to treat infections of the skin, throat, ears, nose, stomach, lungs, and urinary tract infections (UTI).

    Proper Use of this medication

    Typical Dosages of AMOXIL

    Your dose of AMOXIL will depend on how severe your infection is and what type of infection you have.

    Doctors determine children's doses based on the type of infection and the child's weight.

    AMOXIL comes in both capsules and tablets. Adults should take tablets or capsules whole with a glass of water.

    Children's AMOXIL comes in chewable tablets and liquid form.

    You can take AMOXIL with or without food.

    A common dose of AMOXIL for an adult with a mild to moderate ear, nose, or throat infection is 500 mg every 12 hours or 250 mg every 8 hours until the prescription is finished.

    For a more severe infection, a common dose of AMOXIL is 875 mg every 12 hours or 500 mg every 8 hours.

    A common dose of AMOXIL for a child (older than 3 months) with a lower respiratory tract infection is 40 mg per kilogram (kg) of weight per day in divided doses every 8 hours.

    Or, doctors sometimes want the child to take 45 mg per kg per day in divided doses every 12 hours.

    AMOXIL Overdose

    Though rare, it's possible to take an overdose of AMOXIL.

    If you or someone else takes too much medicine, call your local poison control center at 1-800-222-1222.

    If the person collapses, stops breathing, or has any severe symptoms after an overdose, call 9-1-1.

    Missed Dose of AMOXIL

    Take AMOXIL exactly as directed by your doctor.

    Do not stop taking AMOXIL on your own. Skipping doses or stopping too soon can make your infection harder to treat.

    If you miss a dose of AMOXIL, take the missed dose as soon as you remember.

    If it's almost time for your next dose, skip the missed dose.

    Do not double your dose to make up for the missed dose.

    Side Effects

    Common side effects of AMOXIL include:
    • Upset stomach
    • Diarrhea
    • Vomiting
    • Yeast infection
    Serious side effects of AMOXIL can also occur.

    If you have any of these side effects, stop taking AMOXIL and call your doctor right away:

    • Severe rash
    • Yellowing of the skin or eyes (jaundice)
    • Unusual bleeding or bruising
    • Hives
    • Seizure
    • Excessive tiredness
    • Swelling of the face, lips, or tongue
    • Chest pain
    • Difficulty breathing
    • A peeling or blistering rash
    • Severe or bloody diarrhea

    Warnings and Precautions

    It's important to know that once you start a course of AMOXIL, you should finish the whole course.

    Do not stop taking AMOXIL, even if you feel better; instead, finish your entire prescription.

    Not treating your infection completely can make it come back stronger. Stopping AMOXIL too soon can also lead to bacteria that are resistant to it.

    People refer to antibiotic-resistant bugs as multidrug resistant bacteria or "superbugs." Antibiotic resistance is a growing threat worldwide.

    It's also important to understand that AMOXIL may cause a severe reaction called anaphylaxis if you are allergic to it.

    This reaction, which can be life-threatening, includes hives, swelling of your throat, and difficulty breathing.

    AMOXIL also can interfere with certain types of birth control pills. Women who are using birth control pills should talk to their doctor before taking AMOXIL.

    Elderly adults may need to take lower doses of AMOXIL.

    Always tell your doctor if you have allergies to any medications, especially to antibiotics.

    Let your doctor know about all medications, vitamins, and supplements you are taking.

    Using AMOXIL can be risky if you have certain conditions, so let your doctor know if you have:

    • Allergies
    • Kidney disease
    • Liver disease
    • Mononucleosis
    • Diarrhea
    • Asthma
    • Hives
    • Phenylketonuria (PKU)

    AMOXIL and Pregnancy

    If you're a woman, let your doctor know if you are or may be pregnant, are breastfeeding, or using birth control pills.

    Though AMOXIL is widely believed to be safe, ask your doctor if the risks of taking antibiotics while pregnant outweigh the benefits.

    Also, let your doctor know if you are breastfeeding because AMOXIL can pass through breast milk and increase the risk for a later allergic reaction in babies.

    AMOXIL for Dogs

    AMOXIL is often prescribed for dogs and cats that have bacterial infections.

    Amoxi-Tabs is one brand name of this antibiotic; it's also available as a capsule and a liquid.

    AMOXIL is usually well-tolerated by most pets, and side effects are few. The drug can be given with food.

    Give AMOXIL to your dog or cat according to your veterinarian's instructions, and don't stop giving the drug until the entire course of treatment is completed.

    Interactions with this medication

    Some drugs may affect the way AMOXIL works, and AMOXIL may affect other drugs you are taking, causing problems.

    It's very important to let your doctor know about all drugs you are taking, including any over-the-counter (OTC) vitamins, herbs, or supplements.

    AMOXIL may make certain types of birth control pills less effective.

    Drugs known to interact with AMOXIL include:

    • A drug called allopurinol (Lopurin, Zyloprim), used to treat gout, high levels of uric acid in the body, and kidney stones
    • Another drug used to treat gout, called probenecid(Benemid)
    • Other antibiotics, including chloramphenicol, sulfonamides, macrolides, and tetracycline

    If you are a diabetic and you test your urine for sugar, you should know that taking AMOXIL can affect some urine tests. Ask your doctor about urine testing while on AMOXIL.

    AMOXIL and Alcohol

    Drinking alcohol while taking AMOXIL is generally considered safe, and it won't decrease the effectiveness of AMOXIL.

    However, taking antibiotics such as AMOXIL may cause an upset stomach, and alcohol can make this and other side effects worse.
