- Other infections, such as sexually transmitted diseases, bone infections or scarlet fever
- if you are allergic to erythromycin or any of the other ingredients of this medicine (listed in section 6).
- if you are currently taking a medicine called
- ergotamine or dihydroergotamine (used to treat migraines) while taking erythromycin as this may cause serious side effects.
- terfenadine or astemizole or mizolastine (widely taken for hayfever and allergies), domperidone (for nausea (feeling sick) and vomiting (being sick)), cisapride (for stomach disorders) or pimozide or amisulpride (for psychiatric conditions) while receiving erythromycin, as combining these drugs can sometimes cause serious disturbances in heart rhythm. Consult your doctor for advice on alternative medicines you can take instead.
- simvastatin (used to lower cholesterol and triglycerides (types of fat) in the blood).
- tolterodine (used for treating overactive bladder with symptoms of urinary frequency, urgency, and leakage)
- lomitapide (used to lower increased blood fats such as cholesterol and triglycerides). Taking this medicine at the same time as erythromycin may lead to a rise in enzymes produced by liver cells (transaminases), which indicates that the liver is under stress and may lead to liver problems
- if you have abnormally low levels of potassium or magnesium in your blood (hypomagnesaemia or hypokalaemia).
- if you or someone in your family has a history of heart rhythm disorders (ventricular cardiac arrhythmia or torsades de pointes) or an abnormality of the electrocardiogram (electrical recording of the heart) called “long QT syndrome”.
Talk to your doctor or pharmacist before taking Erythrocin® Tablets:
- if you have any liver problems or have been told that any drugs you are taking can cause liver problems
- if you have previously experienced diarrhoea following the use of antibiotics;
- if you are pregnant and have been told that you have a sexually transmitted disease called syphilis. In this case erythromycin may not be effective for preventing the transfer of this infection to your baby. Consult your doctor before receiving erythromycin. Alternatively, if you were treated for early stages of syphilis during your pregnancy, and your child is under 1 year and is prescribed erythromycin, consult your doctor before giving erythromycin to your child.
- if you suffer from a condition called myasthenia gravis, which causes muscle weakness, consult your doctor before receiving erythromycin.
- if you are taking erythromycin with ‘statins’ such as simvastatin or lovastatin (used to lower cholesterol) as serious side effects can occur.
- if you are taking other medicines which are known to cause serious disturbances in heart rhythm.
- if you have heart problems.
If you are treating a young child with antibiotics and they are irritable or vomit when fed, you should contact your physician immediately.
