About Amoxicilin

Amoxicillin is a penicillin antibiotic used to treat bacterial infections, including bacterial pneumonia, dental abscesses, and urinary tract infections. It is ineffective against viral infections. Amoxicillin works by killing bacteria, including inhibiting specific processes in bacterial cells.

Amoxicillin is available as amoxicillin pills, chewable tablets, or oral suspension. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed. The medication is available as a generic formulation as generic amoxicillin, as well as under different brand names. Common brand names include Amoxil®, Moxilin®, Sumox® and Trimox®

If you're prescribed amoxicillin, complete the entire antibiotic treatment course unless your doctor tells you to stop. The antibiotic will only fully treat your bacterial infection if you finish your prescription. Otherwise, you may be at risk of developing antibiotic resistant bacteria.

Amoxicillin uses

There are several FDA-approved uses for amoxicillin, but your healthcare provider may also prescribe it off-label to treat other medical conditions.

Your doctor may prescribe amoxicillin for the following reasons or other reasons not listed here. Ask your online doctor or pharmacist if you have questions about why a medication is prescribed.

  • Pneumonia

    Amoxicillin is approved to treat bacterial pneumonia and other bacterial respiratory infections.

  • Bacterial sinus and ear infections

    Amoxicillin is FDA-approved to treat bacterial sinus infections and ear infections, including otitis media, and nose and throat infections in adults and children over 12.

  • Urinary tract infections (UTIs)

    Amoxicillin is FDA-approved for the treatment of urinary tract infections. It kills bacteria and prevents growth, eliminating harmful bacteria from the urinary tract.

  • Tonsillitis

    Your doctor may prescribe amoxicillin to treat tonsillitis.

  • Stomach ulcers

    Amoxicillin is FDA-approved to treat stomach ulcers and other bacterial infections caused by H. pylori. Your doctor may prescribe other prescription drugs and antibiotics in conjunction with amoxicillin to treat stomach ulcers caused by H. pylori.

How to take amoxicillin

Your pharmacist will provide you with instructions on how to take your amoxicillin prescription. Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

Amoxicillin is available in several forms and doses, including amoxicillin capsules, tablets, and oral suspension. Adults, teenagers, and children typically take between 250 mg and 500 mg every 8 hours or between 500 mg and 875 mg every 12 hours.

Make sure to follow the entire course of antibiotic treatment, even if your symptoms improve. You may develop antibiotic resistance if you don't finish your amoxicillin prescription.
