Adventin (Amoxicillin + Clavulanic Acid) – Antibiotic Tablet Overview

What it is

Adventin is a brand of amoxicillin + clavulanic acid, a combination antibiotic that belongs to the penicillin family. It contains two active ingredients: amoxicillin (a penicillin-type antibiotic that kills bacteria) and clavulanic acid (a beta-lactamase inhibitor that prevents bacteria from becoming resistant to the antibiotic).

What it's used for

Adventin is used to treat infections caused by certain bacteria that produce beta-lactamase enzymes. The approved uses include lower respiratory tract infections (such as bronchitis and pneumonia), acute bacterial otitis media (middle ear infection), sinusitis, and skin and skin structure infections. It works against bacteria like Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, and Escherichia coli that are sensitive to the medicine.

How it's taken

Adventin is taken by mouth as a tablet. The dose depends on the patient’s weight, age, and the infection being treated. Adults weighing more than 40 kg typically take either 250 mg or 500 mg (based on the amoxicillin part) every 8 hours, or 500 mg or 875 mg every 12 hours. Children aged 12 weeks and older receive a weight-based dose, and infants under 12 weeks are given a lower dose divided every 12 hours. Always follow your doctor’s prescription exactly. Do not stop the medicine early, even if you feel better.

Common side effects

The most common side effects reported with Adventin are diarrhoea or loose stools (affecting about 9% of people), nausea (3%), skin rashes and hives (3%), vomiting (1%), and vaginitis (1%). Serious allergic reactions, including anaphylaxis and severe skin reactions, can occur but are rare. If you notice any severe or worsening symptoms, contact your doctor immediately.

Important cautions

Do not take Adventin if you have ever had a serious allergic reaction (such as anaphylaxis or Stevens-Johnson syndrome) to amoxicillin, clavulanate, or other beta-lactam antibiotics like penicillins or cephalosporins. Also avoid it if you have had liver problems (cholestatic jaundice or liver damage) from amoxicillin + clavulanate in the past. Watch for signs of severe skin reactions, liver issues (yellowing of skin or eyes, dark urine), or diarrhoea that does not go away. Patients with mononucleosis (glandular fever) are more likely to develop a rash. Seek medical care if any of these occur.
