Tetralysal is an antibiotic used to treat acne and other bacterial infections. It comes in a capsule that you swallow, typically once a day.
Tetralysal works by targeting bacteria, preventing them from growing and multiplying. The medication is particularly effective against acne as it works against a type of bacteria called Propionebacterium acnes. This is the bacteria which causes acne, feeding on the oils which are produced by the sebaceous glands.
Tetralysal will start to work a week after taking it. You should notice a difference in your skin a couple of weeks after taking Tetralysal daily.
The active ingredient in Tetralysal is lymecycline, which is an antibiotic.
Acne is a condition where spots, pimples and blackheads appear on your skin. You can experience acne at any age, though it often starts in childhood. When the pores in your skin become blocked with excess oil and dead skin cells, you may experience acne. There are many underlying causes of acne. These include hormonal changes, the menstrual cycle, pregnancy and menopause.

Tetralysal contains lymecycline, which can occasionally cause allergic reactions, such as a skin rash. If you experience this or any signs of a serious allergic reaction after taking the medication get immediate medical help and speak with a doctor as soon as possible. Signs of a serious allergic reaction as the development of hives, facial or lip swelling, difficulty breathing, chest tightness or dizziness.

The standard dose of Tetralysal to treat acne is one capsule, or 300 mg, per day. Always take Tetralysal as your doctor or pharmacist has prescribed.
Tetralysal should be taken once a day in the morning. Swallow the capsule whole with a glass of water. You can take Tetralysal with a small amount of food to avoid feeling sick.
Take Tetralysal for as long as your doctor has prescribed. To treat acne, this is usually eight weeks. Always complete the treatment course, even if your acne clears up. Otherwise your acne symptoms might return.
If you take too much Tetralysal it is unlikely to cause you harm. Speak to your doctor or healthcare professional for advice as soon as possible.

Tetralysal can build up in teeth and bones that are still growing, which can lead to permanent staining. This is why Tetralysal is not suitable for children under 12 years old or pregnant women. Tetralysal is unlikely to stain adult teeth.
Thrush is a possible side effect while taking Tetralysal. This is because Tetralysal is a broad spectrum antibiotic, so it can kill some of the protective bacteria you normally have on your body. When this happens, an overgrowth of fungus can occur that leads to a yeast infection, commonly known as thrush.
There are alternative treatment options available for acne. You will usually start with over the counter remedies from a pharmacy. If these do not help treat your acne, you can see a doctor to get prescription only medicines. They may prescribe antibiotics, retinoids, azelaic acid or benzoyl peroxide.
