Keflex

Keflex is a cefalexin medicine. Infections caused by bacteria in the middle ear, sinuses, throat and tonsils, chest and lungs, skin and soft tissue, and kidneys and bladder are the ones covered in its consumer medicine information.

This listing shows cefalexin 250 mg and 500 mg. It does not name the manufacturer of the capsules supplied, so check the label on the pack you receive and confirm with your prescriber or pharmacist that it matches your prescription.

Prices below are all for 500 mg. These examples are calculated from the listed prices at the shop’s Australian-dollar rate on 8 October 2026, before delivery or other checkout charges.

Starting from the 90 pack, the capsule price is about 4.1% lower in the 120 pack and about 12.5% lower in the 360 pack.

A lower price per capsule means a larger upfront payment. Choose only the quantity and strength appropriate to your prescription, and check the expiry date. Prices can change, so confirm the current pack price before ordering.

Keflex is sponsored by Aspen Pharmacare Australia; its 250 mg and 500 mg capsules are listed on the ARTG, and the leaflet also covers an oral suspension. Ibilex is a further cefalexin brand.

An allergy to cefalexin, to penicillin, to another cephalosporin or to an ingredient of the capsule is a reason not to take Keflex. Caution applies with kidney or liver disease, and pregnancy or breastfeeding should be discussed with the doctor. The leaflet names probenecid and metformin as interacting medicines.

Capsules may be taken with or without food, at the prescribed dose and for the full course. Diarrhoea, nausea, vomiting, stomach pain, headache, dizziness, tiredness and thrush are among the commoner effects. A severe allergic reaction, severe bloody diarrhoea with fever, a seizure, jaundice or confusion needs urgent medical help, and persistent diarrhoea is linked to a risk of severe colitis. The leaflet gives storage below 25 °C for 250 mg and below 30 °C for 500 mg. Follow the storage directions on the pack you receive.

Standard delivery: 14–22 days. Express tracked delivery: 7–14 days, with the tracking number sent by email. These are estimated delivery times, not guaranteed arrival dates.
