What is Tetralysal?

Tetralysal is an oral medication. It is the brand name for Lymecycline, which is a broad-spectrum tetracycline antibiotic.

Tetralysal's active ingredient is lymecycline, which is absorbed via an active transport process across the intestinal wall.

You are only able to buy Tetralysal capsules when you have a prescription from your doctor. On prescription, it is available to be bought from a UK registered pharmacy, such as Medicine Direct.

What is Tetralysal used for?

Tetralysal is very commonly used to treat acne. Thanks to its anti-inflammatory properties, this medicine is very effective at reducing the redness and inflammation caused by outbreaks, making it one of the most effective acne treatments available.

Aside from acne break outs, the properties within Tetralysal capsules are also beneficial for treating the formation of blackheads and whiteheads. These capsules are very effective at fighting against bacteria; by stopping the build up of bacteria in the body, Tetralysal can rapidly diminish the appearance and formation of spots.

This course of acne treatment usually lasts for a minimum of 8 weeks.

Who can take Tetralysal?

Tetracycline antibiotics such as Tetralysal are some of the most common medicines used to treat acne, but they are not suitable for everyone.

In order to ensure that this medicine is safe for you to use, you should speak to your doctor before you use Tetralysal if one or more of the below applies to you:

  • You have lupus
  • You have kidney problems
  • You have liver problems
  • You have myasthenia gravis
  • You have had an allergic reaction to lymecycline or any other medicine in the past

Tetralysal is not usually recommended as a treatment for women who are pregnant or breastfeeding.

You should inform your doctor if you are currently pregnant, trying to get pregnant, think you may be pregnant or are currently breastfeeding. Your doctor may give you a prescription for a different form of treatment for your acne, which may be more suitable for your condition.

While it is widely prescribed to treat teenage acne, it is not suitable for children under 12 years of age.

If you have any questions or concerns at all, you should speak to your doctor before you start to use this treatment.

Possible side effects

As with all medicines, Tetralysal comes with the risk of certain side effects.

Not everyone will experience side effects while taking Tetralysal capsules, but you should speak to your doctor if any of these common adverse reactions concern you or don't go away. Do not stop taking the treatment without consulting your doctor:

  • Stomach pain
  • Headaches
  • Diarrhoea
  • Visual disturbances
  • Feeling sick

This list is not exhaustive. For a full list of more serious adverse effects from Tetralysal capsules, you should refer to the Side Effects tab on this page.

Tetralysal Dosage

Our pharmacists and prescribers follow NICE prescribing guidelines when prescribing Tetralysal Capsules.

The usual recommended dose for this medication is 300mg. You should always follow your doctor's instructions precisely and always ensure you read the information leaflet that will come with your capsules, before you start to take the medicine.

You should take one capsule each day, ideally in the morning.

These capsules should always be swallowed whole with a drink of water.

There are no specific instructions as to whether you should take this tablet with food or not, but you are less likely to feel sick if you take it with a meal.

If you are taking Tetralysal to treat acne, you will normally be recommended to take it for at least 8 weeks. Your treatment should be reviewed after three months, to determine whether your acne treatment has been effective. If you have not noticed an improvement after this time, your doctor will probably suggest a different course of treatment.

For the most effective treatment, Tetralysal capsules should be used alongside a non-antibiotic topical treatment; this will decrease the chance of resistance of bacteria in your body. Your doctor may give you a prescription for one of these treatments.

It can be combined with certain over the counter creams that contain benzoyl peroxide for a more effective treatment, also.

What if I take too much?

An extra dose of Tetralysal is unlikely to harm you, but you should speak to your doctor if you become concerned or take more than one extra dose of the medicine.

What if I forget to take it?

If you miss a dose accidentally, don't worry; just take it as soon as you remember to, unless it is almost time for your next scheduled dose of Tetralysal.

If it is almost time for your next scheduled dose, you should skip the missed dose altogether.

Never take a double dose of medicine to try and make up for missing out a dose.

To ensure you do not forget to take your dose, it is best to take Tetralysal at the same time every day, so you get into the routine of taking it. Some people also find it helpful to set an alarm as a reminder to take it.

Tetralysal FAQ's

How does Tetralysal work?

Tetralysal is a tetracycline antibiotic. It works by inhibiting the bacteria that causes acne, known as propionibacte-rium acnes.This common type of bacteria feeds on the sebum produced by the sebaceous glands within your skin. As a result, waste products and fatty acids are produced, which irritate the sebaceous glands, causing your skin to become inflamed and react by developing spots. Tetracycline antibiotics like Tetralysal inhibit the bacteria's ability to produce the proteins they need to reproduce, stopping the spread of infection and reducing the inflammation.

How do I buy Tetralysal online?

You can only purchase Tetralysal capsules online if you have been given a prescription for the medicine by your doctor. If you have been prescribed this treatment for acne by a doctor, you are able to order it online at a UK regis-tered pharmacy like Medicine Direct.
