Infections cefadroxil treats

Cefadroxil is a cephalosporin antibiotic, used for infections caused by bacteria rather than viruses. Urinary tract infections, skin infections and throat infections such as tonsillitis are what it is given for most often, along with some chest and sinus infections caused by bacteria likely to respond to it. Colds, flu and other viral illnesses are not affected by it.

PockDose sells cefadroxil as Cefadroxil capsules in 250mg and 500mg, part of the antibiotics sold here.

How it works

Each bacterium is wrapped in a mesh-like wall. Cefadroxil stops the cross-links in that mesh from forming, the wall gives way and the bacterium bursts instead of dividing. It is absorbed from the gut into the blood and carried to the infected tissue, whether that is the kidney, skin or throat.

When to take it, and how long for

Imagine day three: the burning on passing urine, or the sore skin, has mostly gone, and the box still has capsules in it. This is when courses get abandoned. The remaining capsules deal with the bacteria that are left, and an infection stopped halfway tends to come back harder to treat, so finish them.

A typical adult schedule is 500mg morning and evening, and some doses are once every 24 hours. The capsules go down whole with water, with or without a meal.

Side effects worth knowing

Most side effects are minor: loose stools, nausea, stomach pain, vomiting, a rash or itching around the genitals, mostly passing within days.

Watery or bloody diarrhoea with cramps or a fever, during the course or in the two months after the last capsule, can mean a serious bowel infection and needs urgent treatment. Hives, wheezing, trouble swallowing or swelling of the face, throat or tongue is an allergic emergency. Yellowing of the eyes or skin, dark urine, pain under the right ribs or pale, clay-coloured stools suggest a liver problem.

Medicines and allergies to keep in mind

Gout treatment with probenecid keeps cefadroxil in the body longer because the kidneys clear it more slowly. A few blood thinners and other antibiotics interact too. Anyone who has had a severe penicillin reaction is more likely to react to cefadroxil as well, as the two families are related. Leave capsules in their container, closed, in a cool dry place away from children.

Can I order Cefadroxil online in Hong Kong?

Cefadroxil can be ordered online from PockDose with delivery to Hong Kong. The range here is Cefadroxil capsules in 250mg and 500mg. Every order is sent in plain, unbranded packaging, so the outside gives no clue about the contents.

How are Cefadroxil prices shown?

The price depends on the strength and pack size you choose. The Cefadroxil page shows current prices in HKD or the currency you select.

Do I need a prescription to order Cefadroxil?

PockDose does not ask you to upload a prescription when you order cefadroxil. See the ordering FAQ for details.

What brand names does cefadroxil have?

Duricef is a brand name of cefadroxil, which is also sold as Droxyl and Odoxil. Here, cefadroxil can be bought online as cefadroxil capsules. These are generics, not the original brand.

Can I drink alcohol with cefadroxil?

Yes; cefadroxil does not react with alcohol, and food is unrestricted. Heavy drinking can add to nausea and an upset stomach, so a quiet few days until the capsules run out is easier on you.

Does cefadroxil affect the pill?

Cefadroxil does not make hormonal contraception less reliable; only enzyme-inducing antibiotics such as rifampicin and rifabutin do that. Vomiting or severe diarrhoea can still lower the protection of the pill, patch or ring, so cover can dip until it settles.

What is the difference between cefadroxil and cephalexin?

Both are first-generation cephalosporins used for similar infections, but they are dosed differently: cefadroxil every 12 or 24 hours, cephalexin usually every 6 hours. Cefadroxil's longer action is why twice-daily dosing works.

Is cefadroxil the same as amoxicillin?

No — amoxicillin belongs to the penicillin family and cefadroxil to the cephalosporins, which are related but separate. They cover a similar range of common infections and are dosed on different schedules.
