Tetralysal is an antibiotic capsule that’s usually prescribed to treat acne, but it can also help with other types of skin infection.
The recommended dose is usually one pill every day (in the morning), and you’ll likely take it for up to eight weeks. It’s important to take your full course of Tetralysal, even if your symptoms clear up. This is to stop the bacteria from becoming resistant to the treatment and coming back.
Acne is usually caused by one of two things. Hormonal changes or large groups of bacteria clogging up your pores. Tetralysal works by targeting acne-causing bacteria that live on your skin.
Our skin glands produce a chemical known as sebum. Sebum helps to keep our hair and skin nice and healthy. Unfortunately, bacteria love sebum. When our sebaceous glands produce too much sebum, bacteria starts to feed on it. The clogging-up of our pours by bacteria is what causes spots, redness, swelling and other symptoms of acne.
The main ingredient in Tetralysal is lymecycline. Lymecycline is an antibiotic that targets bacteria and stops it from producing the proteins that it needs to survive. Once lymecycline has starved the bacteria of its much-needed proteins it’s then weakened and killed by your body's immune system.
There’s only one dose of Tetralysal, which is a 300mg capsule. The usual recommended treatment for acne is one of these pills a day, in the morning, for up to eight weeks.

When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from.

You should always follow the instructions of your clinician when taking Tetralysal, as well as paying attention to the leaflet that comes with your treatment.
Like with all antibiotics for acne, it can often take up to several weeks before you notice any difference. The length of time that it takes to treat acne can vary from person to person, and will depend on the severity of your acne as well as your own personal response to the treatment. If you don’t see any benefits from the treatment after eight weeks then have a chat with our clinician. They’ll help you look for alternatives that might work better for you.
Fortunately, overdoses on antibiotics are very rare. That being said, it’s important that you do not take more than your daily prescribed amount. If you do miss a dose just be sure to take it as soon as you can. It’s recommended that you take your capsule in the morning, but so long as one tablet is taken per day it should still be safe and effective.
