1. What Tetralysal is and what it is used for

Tetralysal belongs to a group of antibiotic medicines called tetracyclines.
The main use of Tetralysal is to treat moderate to severe acne. Acne appears as
an inflammation of the skin, presenting with papules (small raised skin lesions without pus),
pustules (small skin lesions containing pus), blackheads and pimples.

2. What you need to know before taking Tetralysal

Do not take Tetralysal

  • If you are allergic to tetracycline-L-methylene lysine (limecycline) or to any of the other ingredients of this medicine (listed in section 6);
  • Tetralysal is contraindicated in children under 8 years of age due to the risk of permanent discoloration of teeth and enamel.
  • Tetralysal is contraindicated when used concomitantly with oral retinoids (vitamin A-based products taken by mouth).
  • Tetralysal is contraindicated during pregnancy and breastfeeding (see section "Special warnings").

Warnings and precautions
Talk to your doctor or pharmacist before taking Tetralysal.
As with other antibiotics, treatment with tetracyclines may lead to secondary bacterial or fungal (mycotic) infections.
In particular, there is a risk of enterocolitis caused by resistant staphylococci (inflammation of the small intestine and colon due to bacteria resistant to the therapeutic action of the drug).
If you undergo prolonged courses of treatment with Tetralysal, your doctor will prescribe periodic checks of blood composition and liver and kidney function.
In susceptible individuals, skin reactions may occur during treatment following exposure to sunlight or sunlamps. If skin redness (cutaneous erythema) appears, you must stop treatment immediately.
If you have renal impairment, inform your doctor before taking Tetralysal and carefully follow the instructions provided.
Before taking Tetralysal, consult your doctor if you suffer from myasthenia gravis (a disease that causes muscle weakness).
Before taking Tetralysal, consult your doctor if you suffer from systemic lupus erythematosus.
Take the medicine with a sufficient amount of water to avoid irritation and ulcers of the oesophagus.
If you take more Tetralysal than you should (overdose), liver problems (hepatotoxicity) may occur.
Do not take Tetralysal after the expiry date, as this could result in a risk of kidney damage (pseudo-Fanconi syndrome).

Children
Tetralysal must not be used in children under 8 years of age due to the risk of permanent discoloration of teeth and enamel.

Other medicines and Tetralysal
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

  • Do not use Tetralysal together with oral vitamin A-based products due to the risk of increased intracranial pressure.
  • Do not take antacids containing aluminium, calcium, or magnesium, or products containing iron salts, didanosine, activated charcoal, cholestyramine, bismuth chelates, or sucralfate together with Tetralysal, as these reduce the absorption of orally administered tetracyclines.
  • Do not take together with medicines that increase gastric pH, as they reduce tetracycline absorption.
  • Avoid concomitant use with penicillins (another type of antibiotic) due to possible interference between the two drugs.
  • If you are being treated with anticoagulant medicines (medicines to prevent blood clots), inform your doctor, as the dosage may need to be adjusted due to the possible reduction in anticoagulant activity caused by tetracyclines.
  • Do not take together with antiepileptic medicines, including barbiturates such as phenobarbital, phenytoin, and carbamazepine.
  • The use of methoxyflurane in combination with Tetralysal is not recommended, as it may cause fatal renal toxicity.
  • Limecycline (the active ingredient in Tetralysal) may cause false positive results in urine glucose tests.
  • Inform your doctor if you are taking lithium, as this medicine may increase lithium levels.

Pregnancy, breastfeeding and fertility
If you are pregnant, suspect you may be pregnant, are planning a pregnancy, or are breastfeeding, consult your doctor or pharmacist before using this medicine.
The use of tetracyclines during tooth development (second half of pregnancy) may cause permanent yellow-brown discoloration of the child's teeth. This is particularly observed with prolonged use, but has also been reported after short, repeated treatment courses. For this reason, the use of Tetralysal is contraindicated during pregnancy and breastfeeding.

Fertility
No data are available on effects on fertility.

3. How to take Tetralysal

Take this medicine exactly as instructed by your doctor or pharmacist. If you have any doubts, consult your doctor or pharmacist.
The recommended dose for the treatment of acne is 300 mg/day for 12 weeks.
You should take the product with an adequate amount of water to avoid irritation and ulceration of the oesophagus.

Use in children
Tetralysal must not be used in children under 8 years of age due to the risk of permanent discoloration and enamel damage of the teeth.

If you take more Tetralysal than you should
If you have accidentally taken an excessive dose of Tetralysal, inform your doctor immediately or go to the nearest hospital.
If you have any doubts about the use of this medicine, consult your doctor or pharmacist.

The following side effects are listed by frequency:
Common (may affect up to 1 in 10 people):

  • Headache
  • Nausea
  • Abdominal pain
  • Diarrhoea

Not known (frequency cannot be estimated from the available data):

  • Enterocolitis (inflammation of the small intestine and colon)
  • Glossitis (inflammation of the tongue)
  • Visual disturbances*
  • Neutropenia (reduction in neutrophils, a type of white blood cells)
  • Thrombocytopenia (reduction in platelets)
  • Vomiting
  • Upper gastrointestinal tract pain (in the stomach)
  • Fever
  • Jaundice (yellowing of the skin)
  • Hepatitis (inflammation of the liver)
  • Hypersensitivity
  • Urticaria
  • Angioneurotic edema (swelling of the eyelids, lips, tongue, genital organs)
  • Anaphylactic reaction (severe, rapidly developing allergic reaction that may be fatal)
  • Increased transaminases (liver enzymes in the blood indicating possible liver damage)
  • Increased alkaline phosphatase (blood enzymes indicating certain diseases)
  • Increased bilirubin (a substance contained in bile)
  • Dizziness
  • Intracranial hypertension (increased pressure within the skull)
  • Erythematous rash (appearance of red skin lesions)
  • Photosensitivity reactions during exposure to sunlight or sunbeds
  • Pruritus (itching)
  • Stevens-Johnson syndrome (a severe acute hypersensitivity reaction affecting the skin and mucous membranes)
  • Depression
  • Nightmares

*(the occurrence of clinical symptoms, including visual disturbances or headache, may be related to intracranial hypertension. If increased intracranial pressure is suspected during treatment with limecycline, administration must be discontinued).
Benign intracranial hypertension has been reported with tetracyclines, with possible symptoms including headache, vomiting, visual disturbances such as blurred vision, scotoma (dark spots or intermittently flickering vision in the visual field), diplopia (double vision), or permanent vision loss.

Additionally:

  • When administered in children under 8 years of age, permanent discoloration of teeth and enamel abnormalities may occur.
  • Cases of haemolytic anaemia (low haemoglobin concentration), eosinophilia (increase in certain blood cells), and other blood disorders have been reported.
  • Cases of non-renal hyperazotemia (increased blood nitrogen levels) may occur due to concomitant use of diuretics (medicines used to increase urine secretion) and tetracyclines.
  • Treatment with Tetralysal must be discontinued if symptoms suggestive of increased intracranial pressure occur (e.g. vomiting).
  • Isolated cases of anorexia (loss or reduced appetite) and allergic vasculitis (inflammation of blood vessels) have been reported.
  • Cases of systemic lupus erythematosus and pancreatitis have been observed, generally attributable to tetracycline therapy.

Following the instructions provided in the leaflet reduces the risk of side effects.
