Amoxicillin is a penicillin-based antibiotic (amino-penicillin) that helps fight bacterial infections. It is one of the most widely used antibiotics in the primary care setting and works against a wide variety of gram-positive bacteria and some gram-negative bacteria as well.
It is effective only against bacterial infections and not viral diseases. It is often prescribed for patients with chest infections or ear infections. Amoxicillin is not an over-the-counter medicine and can be bought only with a doctor’s prescription.
Amoxicillin can be used by a doctor to treat the following conditions:
Bacterial Pharyngitis
Bacterial sinusitis
Bronchiectasis
Bronchitis-Tonsillitis
Chest Infections (E.g. Pneumonia)
Dental Abscesses
Ear Infections like Otitis Media
Helicobacter Pylori Infection
Lyme Disease
Nose Infections
Skin Infections
Stomach/Intestinal ulcers
Urinary infections
Amoxicillin is available as an oral medication in the form of capsules, soluble tablets, powdered sachets, and liquid medicine. Amoxicillin injections are also available.
The doctor may prescribe different forms of Amoxicillin depending upon the infection and the patient’s condition. Here are a few important points to note regarding amoxicillin:
Always read the leaflet that comes with the medicine to understand its details. For liquid medications for children, follow the dosage. Read the instructions carefully. Oral liquid medications must be shaken well before use.
Oral tablets can be swallowed with some water. It is also available as chewable tablets.
If the doctor has prescribed powdered sachets, they must be dissolved in 10–20 ml (or as per the package instructions) of water and taken immediately.

Even if the infection appears to subside, complete the full course of treatment prescribed by the doctor. Stopping the medication way too early may cause the bacteria to regrow.
Those who are allergic to penicillin or any other penicillin antibiotic should never take amoxicillin. So, always inform your doctor if you have any allergies.
