What is Azithromycin?

Azithromycin is an antibiotic that is prescribed to treat a variety of bacterial infections. It is a prescription-only medicine that is used by adults and children for different conditions. It is available in packets of 4 tablets.

You can buy Azithromycin online at Medicine Direct following an online consultation with one of our certified doctors. They will assess your symptoms and medical history and prescribe Azithromycin if they deem it the most appropriate treatment for you to take. You can then buy it from our registered pharmacy, and if you order by 2pm you will receive your order the very next day.

What is Azithromycin used to treat?

This medication is a common treatment for the sexually transmitted infection, chlamydia.

Azithromycin is a macrolide-type antibiotic, which works by stopping the production of protein in bacteria, which stops it from growing and replicating. By doing this, the bacterial infection cannot spread and you immune system is able to kill off what remains in your body.

A broad-spectrum antibiotic, Azithromycin is able to fight a large range of different bacterial infections. It comes in packets of 4 tablets.

Aside for being an effective chlamydia antibiotic, it can also be used in the treatment of skin, soft tissue, ear and airways infections.

How Azithromycin treats chlamydia

As a treatment for chlamydia, Azithromycin tablets is one of the most common forms of antibiotic, alongside Doxycycline. Both of these medicines fight chlamydia in the same way; they prevent the bacteria from reproducing.

A course of Azithromycin antibiotics will provide effective chlamydia treatment in 95% of cases, if the tablets are taken as instructed by a doctor. It is very important you read the patient information leaflet thoroughly and follow your doctor or pharmacist's instructions carefully.

The dose of Azithromycin tablets when used as chlamydia antibiotics is two 500mg tablets, to be taken at the same time for one day. After that, the dose is one tablet once a day for two days.

Women who are pregnant or breastfeeding may be prescribed a different medication.

When will a doctor prescribe Azithromycin for you?

A doctor will prescribe Azithromycin tablets for you after an examination of your symptoms for the likes of ear and skin infections.

As an antibiotic for chlamydia, they will prescribe it if you have been found to have the infection.

If you fear you might have chlamydia, you should get a home chlamydia test kit as soon as you can. You can take the test at any time, but if you have had unprotected sex within two weeks before getting tested, you might want to get tested a second time later on. Most chlamydia tests will either be a urine test or swab.

Nine out of 10 chlamydia tests are accurate, and most sexual health clinics and GPs offer free testing. Tests can also be bought online for home testing.

If there is a high risk that you have chlamydia, such as having unprotected sex with a partner who is known to have the infection, your doctor might prescribe antibiotics for chlamydia before the tests come back.
