Biaxin must not be taken at the same time as the following medicines:
- medicines intended to stimulate gastrointestinal activity (medicines containing cisapride as the active substance);
- neuroleptics (containing pimozide as the active ingredient);
- sedatives or sleep-inducing drugs (benzodiazepines, e.g. with the active ingredient midazolam);

- anti-gout medication (containing the active ingredient colchicine);
- anti-platelet agents (containing the active substance ticagrelor);
- medicines for the treatment of psychosis (containing the active substance quetiapine);
- medicines to treat heart conditions (containing the active substance ranolazine);
- medicines for the treatment of nausea and vomiting (containing the active substance domperidone).
Biaxin must not be taken if:
- you have a history of heart rhythm disorders (ventricular tachycardia, including torsades de pointes) or if a special change in the electrocardiogram, QT prolongation, has been observed.
- you have a potassium or magnesium deficiency (hypokalaemia or hypomagnesaemia) or
- you suffer from severe liver failure in association with renal insufficiency.
How To Take
Biaxin should be taken as directed by your doctor.
In adults and adolescents over 12 years of age, the usual daily dose is 2x 1 film-coated tablet of 250 mg (= 500 mg); take the tablets morning and evening. If necessary, your doctor may increase this dosage.
For infections caused by non-tuberculous mycobacteria, the recommended dose for treatment and prevention is 2x 1 film-coated tablet of 500 mg per day (= 1000 mg).
For the eradication of Helicobacter pylori, the recommended dosage is 2x 1 film-coated tablet of 500 mg (= 1000 mg) Biaxin per day, with 2x 1000 mg amoxicillin per day and 1-2x 20 mg omeprazole per day for 7-10 days.
Swallow Biaxin film-coated tablets without chewing. The medicine may be taken independently of meals, i.e. on an empty stomach or with meals.
Duration of treatment: In general, the duration of treatment is 7 to 14 days. However, depending on the nature of your illness, your doctor may also prescribe Biaxin for a longer period, particularly in cases of infection due to non-tuberculous mycobacteria.
Biaxin is not suitable for the treatment of children under the age of 12. A special formulation (children's suspension) is available for the treatment of children.
Any antibiotic therapy started must be continued for as long as prescribed by the doctor. The symptoms of the disease often disappear before the infection is completely cured. Too short a course of treatment or stopping treatment prematurely may encourage a relapse of the disease.
Side Effects
Biaxin may cause the following side effects:
Common: insomnia, headache, dazedness, changes in taste, nausea, vomiting, loose stools and diarrhoea, feeling of pressure in the upper abdomen (in rare cases convulsively), digestive disorders, itching, skin rash, increased sweating, lack of strength.
Tell your doctor immediately if you experience severe or persistent diarrhoea during or after treatment with Biaxin.
In the event of diarrhoea, medicines that inhibit intestinal peristalsis (the movement of the intestine) must not be taken.
Severe allergic reactions have been observed in rare cases. Contact your doctor immediately in the event of allergic symptoms such as skin rash, facial oedema or respiratory distress.
Occasional: disturbance of the sense of smell and reversible discolouration of the tongue and teeth (usually blackish or dark brown, especially when Biaxin and omeprazole are used together), inflammation of the tongue or oral mucosa, belching, fungal infections of the skin/mucosa.
Consult your doctor if you discover whitish deposits in your mouth or if the lining of your mouth or tongue is inflamed.
The following symptoms may also occasionally occur: loss or reduction of appetite, constipation, dry mouth, bloating, anxiety, dizziness, tremor, drowsiness, hearing impairment with reversible partial deafness, tinnitus, palpitations, malaise, chest pain, tiredness, chills.
In rare cases, Biaxin, like other medicines of the same type, has been held responsible for disorders of the liver, pancreas or kidneys. Consult your doctor if you experience abdominal pain, loss of appetite, tiredness or yellowing of the skin.
Rare cases of convulsions have been reported.
In rare cases, a reduction in blood sugar levels has been observed, particularly with concomitant treatment with certain oral antidiabetics or insulin.
Arrhythmias and ventricular fibrillation have also been observed rarely.
There have been reports of patients with myasthenia gravis worsening on clarithromycin therapy.
There have been reports of patients with muscle pain or muscle disease. Nightmares, confusional states, hallucinations, depression, behavioural changes, acne, tingling, loss of sense of taste and smell may also occur.
Rarely, muscular pain or weakness may occur when taking drugs to lower blood fat levels that are too high (statins), which may be a sign of serious muscular deterioration (rhabdomyolysis).
There have also been reports of haemorrhage in patients receiving oral anticoagulants at the same time.
If any side effects persist for a long time or are quite serious (diarrhoea, for example), report them to your doctor or pharmacist.
If you notice any side effects, please inform your doctor or pharmacist. This applies in particular to side effects not mentioned in this package leaflet.
Precautions
Inform the doctor treating you if:
- you suffer from heart, liver or kidney disease,

- agents liable to cause hearing damage (in particular aminoglycoside antibiotics).
Severe allergic reactions have been observed in rare cases.
Contact your doctor immediately:
- if you develop an itchy skin rash, hives, facial swelling, chest tightness or respiratory distress.
- if you develop a fever, a growing feeling of sickness or a painful rash that spreads, particularly if such a rash is accompanied by blistering and inflammation of the eyes and mucous membranes or if a painful rash of small purulent blisters (pustules) spreads. In such cases, you must stop taking Biaxin immediately and consult a doctor without delay.
Your doctor will check the dosage of these medicines.
Please inform your doctor immediately in the event of severe and continuous diarrhoea during or after the end of treatment with Biaxin.
This medicine may affect reactions, driving ability and the ability to use tools or machines!
What else do you need to consider?
This medicine has been personally prescribed for you by your doctor for the treatment of your current illness.
The antibiotic contained in Biaxin is not effective against all micro-organisms likely to cause infections. Using the wrong antibiotic or at the wrong dosage can cause complications. You should therefore never use this medicine on your own to treat other illnesses or other people.
Pregnancy and Breastfeeding
If you are pregnant, planning to become pregnant, or are breastfeeding, please notify your doctor or pharmacist and avoid taking Biaxin unless expressly advised to do so.
