ERYTHROMYCIN 250 MG / 5ML SUGAR FREE GRANULES FOR ORAL SUSPENSION - Patient leaflet, side effects, dosage

1. WHAT ERYTHROMYCIN IS AND WHAT IT IS USED FOR

Erythromycin contains erythromycin ethyl succinate, which is an antibiotic (macrolide group). It is used to treat or prevent bacterial infections, including sexually transmitted diseases and dental infections. It may be used to prevent whooping cough, diphtheria or to treat certain skin infections (Acne vulgaris).

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE ERYTHROMYCIN

Do not take Erythromycin:

• 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) as this may cause serious side effects while taking erythromycin

• – 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 disturbance in heart rhythm. Consult your doctor for advice on alternative medicine 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 urinary7 frequency, urgency and leakage)

• if you have abnormally7 low levels of potassium or magnesium in your blood (hypomagnesaemia or hypokalaemia)
• if you or someone in your family7 has a history7 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”.

Warnings and precautions

Talk to your doctor or pharmacist before taking Erythromycin:

• if you are taking colchicine (used for treatment of gout and arthritis) as this may7 cause serious side effects whilst taking erythromycin
• if you have any7 liver problems or have been told that any7 drugs you are taking can cause liver problems
• if you have previously7 experienced diarrhoea following the use of antibiotics
• if you are pregnant and have been told that you have a sexually transmitted disease called sy7philis. In this case erythromycin may not be effective for preventing the transfer of this infection to your baby. Alternatively if you were treated for early7 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 are treating a young child with antibiotics and they7 are irritable or vomit when fed
• if you suffer from a condition called myasthenia gravis, which causes muscle weakness
• if you are taking erythromycin with ‘statins’ such as simvastatin or lovastatin (used to lower cholesterol)
• if you are taking other medicines which are known to cause serious disturbances in heart rhythm
• if you have heart problems.

Contact your doctor as soon as possible if y7ou develop watery and bloody stools during or up to 2 months after treatment, with or without stomach cramps and fever (to rule out the possibility of pseudomembranous colitis).

Erythromycin contains sorbitol (E420) and sodium

This medicine contains 1100 mg sorbitol in each 5 ml. Sorbitol is a source of fructose. If your doctor has told you that you (or your child) have an intolerance to some sugars or if you have been diagnosed with hereditary7 fructose intolerance (HEI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you (or your child) take or receive this medicine.

Sorbitol may cause gastrointestinal discomfort and mild laxative effect.

This medicine contains less than 1 mmol sodium (23 mg) per 5 ml, that is to say7 essentially7 ‘sodium free’.

3. how to take erythromycin

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Patients with kidney7 problems must be given a reduced dose.

Shake Erythromycin well before use.

Taking Erythromycin with food and drink: Take Erythromycin before meals.

The recommended doses are:

For adults and children over 8 years of age:

2 g per day in divided doses. In severe infections, this can increase up to 4 g per day7 in divided doses. One to two 5 ml spoonfuls four times a day.

For Acne vulgaris, the dose is one 5 ml spoonful 3 times daily before meals, for 1 to 4 weeks, and then reduced to twice daily until improvement occurs.

For children aged 2 – 8 years:

30 mg per kg of body weight per day in divided doses. In severe infections, this can increase up to 50 mg per kg of bodyweight per day in divided doses. One 5 ml spoonful four times a day7 or as advised by7 your doctor.

For infants under 2 years of age:

30 mg per kg of body weight per day in divided doses. In severe infections, this can increase up to 50 mg per kg of bodyweight per day in divided doses. One 2.5 ml spoonful four times a day7 or as advised by7 your doctor.

An oral syringe may7 be used to measure this dose. A lower strength product containing 125 mg/5 ml of erythromycin is easier to use for this age group.

If you forget to take Erythromycin

Take the dose as soon as you remember, unless it is nearly time for your next dose. Do not take a double dose to make up for the missed dose.

If you take more Erythromycin than you should

If you accidentally take more medicine in one day than your doctor has told you to, or if a child has taken some of the medicine by7 mistake, contact your doctor or go to your nearest hospital emergency department immediately. An overdose could cause temporary7 hearing loss, nausea, vomiting and diarrhoea.

If you stop taking Erythromycin

Continue to take this medicine until the course is completed or until your doctor tells you to stop; do not stop taking your medicine, even if you feel better. If you stop the treatment too early your problem could come back.

If you have any7 further questions on the use of this medicine, ask your doctor or pharmacist.
