Clarithromycin in the form of a suspension is indicated for use in children over 6 months and adolescents up to 12 years of age.

2. Important information before taking Klabax

Do not give Klabax to a child if:

• they are allergic to clarithromycin, other macrolide antibiotics, such as erythromycin or azithromycin, or any of the other ingredients of this medicine (listed in section 6);
• they have too low a level of potassium or magnesium in the blood (hypokalemia or hypomagnesemia);
• they have severe liver disorders combined with kidney function disorders;
• the patient or their family has a history of heart rhythm disorders (ventricular arrhythmias, including torsades de pointes) or abnormalities in the electrocardiogram (ECG, registration of the heart's electrical activity) called "long QT interval syndrome";
• they are taking:
• drugs called ergot alkaloids (e.g., ergotamine or dihydroergotamine) in tablet form or using ergotamine inhalers (used to treat migraines);
• drugs such as terfenadine or astemizole (used to treat hay fever or allergies), cisapride or pimozide. Concurrent use of these drugs may cause severe heart rhythm disorders. You should consult a doctor and establish alternative treatment;
• other drugs that may cause serious heart rhythm disorders;
• midazolam given orally (a sleeping pill);
• tikagrelor or ranolazine (used to prevent heart attack, chest pain, angina pectoris);
• colchicine (usually used to treat gout);
• lovastatin, simvastatin, or atorvastatin (lowering blood cholesterol levels);
• a drug containing lomitapide.

If any of the above situations apply to your child, you should consult a doctor who will recommend alternative treatment.

While taking Klabax, special caution should be exercised

• If the child has too low a level of magnesium in the blood (hypomagnesemia) before taking the medicine, you should consult a doctor.

Warnings and precautions

You should contact a doctor or pharmacist before giving Klabax to a child if:

• they have liver or kidney disorders;
• they are resistant to other antibiotics, such as clindamycin, lincomycin;
• they have heart disorders (e.g., heart disease, heart failure, very slow heart rate)
• they are taking anticoagulant medications, e.g., warfarin (blood "thinning" medications). The prothrombin time should be frequently monitored;
• they are given medications that can impair hearing, e.g., aminoglycosides. If necessary, the doctor should check the child's hearing;
• they are taking medications that lower blood sugar levels. Clarithromycin may enhance their effect;
• they have pneumonia, as the bacteria (Streptococcus pneumoniae) that cause it may be resistant to clarithromycin;
• they have tonsillitis and there is no hypersensitivity or other contraindications to the use of penicillins
• they have a fungal infection or are prone to such infections (e.g., thrush).

If bacteria are resistant to erythromycin A, they may also be resistant to clarithromycin.
You should consult a doctor if any of the above situations occur in your child.
You should stop taking Klabax and contact a doctor if your child:

• experiences severe diarrhea during or after taking Klabax. You should avoid medications that slow down bowel movements (gut motility), such as medications used to treat diarrhea.
• experiences yellowing of the skin (jaundice), skin irritation, dark urine, abdominal pain, or loss of appetite. These symptoms may indicate liver function disorders in the child.
• experiences another infection.

Klabax and other medicines

You should tell the doctor or pharmacist about all the medicines your child is taking or has recently taken, as well as any medicines that will be given.
