Tetralysal 300 is an oral medication used to treat acne. Acne symptoms will present as blackheads and whiteheads, which are often referred to as spots or pimples. Tetralysal is often prescribed when over-the-counter acne treatments have proven ineffective or where moderately severe acne is present that requires prescription treatment.
Tetralysal 300 capsules are manufactured by Galderma. The active ingredient, Lymecycline belongs to a group of medicines called tetracycline antibiotics. Lymecycline is a broad spectrum antibiotic that's effective against a wide variety of bacteria. Tetralysal is predominantly prescribed for the treatment of acne. However, your GP may also use it to treat other bacterial infections, such as chest infections, urine infections, skin infections and mouth infections.
Tetralysal 300 hard capsules contain the active ingredient Lymecycline, an antibiotic. For treating acne, Tetralysal works to inhibit the bacteria associated with causing acne, Propionibacterium. This common type of bacteria feeds on sebum produced by the sebaceous glands in the skin. This causes propionibacterium to produce waste products and fatty acids that can irritate the sebaceous glands. This irritation will cause the sebaceous glands to become inflamed, causing spots to develop. Lymecycline interferes with this bacteria's ability to produce proteins that are essential for their production. This action stops the spread of the infection, reducing the inflammation of the sebaceous glands and allowing the skin to heal. Any remaining bacteria are killed by the immune system or eventually die.
Tetralysal 300 hard capsules are suitable for treating mild to moderate acne where there is an active infection and visible inflammation. The duration of treatment will depend on how quickly your condition improves. For acne, Lymecycline will normally be taken for at least eight weeks. If you have seen no improvement in your acne after 3 months you may wish to discontinue Tetralysal and try a different acne treatment.
Tetralysal capsules can also be used with other topical acne treatments such as creams containing benzoyl peroxide (Epiduo, Quinoderm & Panoxyl) or azelaic acid (Skinoren) that help to dry out the skin, reducing the amount of sebum present.
Tetralysal capsules do not contain penicillin and are not related to penicillin.
- You should take one Tetralysal capsule daily, preferably in the morning.
- Tetralysal capsules should always be taken with a full glass of water.
- For treating acne, you will normally need to take Tetralysal for at least 8 weeks. Treatment should be assessed after 3 months to determine whether it has been effective. If your treatment has been effective, you can continue to take Tetralysal for another 3 months where you should see further improvement. If there has been no improvement in your acne, you should stop taking Tetralysal and consider a different acne treatment.
Like all medicines, Tetralysal capsules can cause side effects including nausea & vomiting, diarrhoea, stomach ache, visual disturbances and dizziness. In rare cases Tetralysal can also cause fungal infections such as thrush, skin reactions, photosensitivity, colitis and pancreatitis.
