What are Erythromycin 250mg Tablets?

Erythromycin 250mg Tablets are antibiotics used to treat a range of short-term (acute) infections. As a broad-spectrum antibiotic, it's used to treat and prevent the growth of a variety of bacteria that cause a number of bacterial infections. It's known to treat:

  • Upper respiratory infections
  • Lower respiratory infections
  • Oral/dental infections
  • Ear infections
  • Eye infections
  • Skin and soft tissue infections
  • Gastro-intestinal infections
  • Other infections including urethritis, gonorrhoea, syphilis, diphtheria and scarlet fever

Erythromycin tablets can be used to treat other conditions as well as those listed above. For the complete list, you can check the patient leaflet attached at the bottom of this page.

The active ingredient, erythromycin, has a similar antibacterial quality to penicillin. Therefore, it is often used as an alternative for those who are allergic to penicillin-based medications.

It is also used pre-emptively to prevent infections in both pre and post-operative trauma, as well as in cases of rheumatic fever and severe burns.

Another common use for Erythromycin 250mg Tablets is to treat acne and rosacea. The latter is a long-term inflammatory disorder of the skin that can cause discomfort and embarrassment.

You must also complete the full course of tablets, even if it feels like your infection has cleared, otherwise it may come back in a form that is resistant to erythromycin.

How do Erythromycin 250mg Tablets work?

Erythromycin 250mg Tablets are macrolide antibiotics. This means the tablets stop erythromycin-sensitive bacteria from producing proteins that are essential to their growth and survival.

A bacterial infection occurs when bacteria within the body overgrow and cause adverse reactions. Erythromycin stops this growth and controls the number of bacteria remaining.

It does not directly kill the bacteria, but they will die out or be destroyed by the immune system once the growth protein is eradicated.

Erythromycin 250mg Tablets are also effective when it comes to the bacteria on the skin that cause acne, known as Propionibacterium acnes.

This type of bacteria feeds on the sebum produced by the sebaceous glands which are present in the skin. The waste and fatty acids the bacteria produce irritate these glands and this leads to inflammation and spots.

By controlling the number of bacteria in the skin, erythromycin alleviates the inflammation and allows the skin to begin to heal.

How to use Erythromycin 250mg Tablets?

  • Take the dose that was advised by your doctor or pharmacist. (This is normally 1 tablet twice a day, or 1 tablet four times a day depending on your condition.)
  • For best results, try to take this medication at evenly spaced intervals throughout the day.
  • The tablets can be taken with or without food.
  • Swallow the tablet whole with a drink of water, do not crush or chew it.
  • If you forget to take one dose, take the missed tablet as soon as you can. However, if it's close to the time for your next dose just skip the forgotten dose and take the next one as normal. Don't take a double dose to make up for a forgotten tablet.

What dosages are available for Erythromycin 250mg Tablets?

There is only one dosage available. Each 250mg tablet contains 250mg erythromycin and is gastro-resistant due to its enteric coating. This means that the tablets do not dissolve in the stomach acid and release their active ingredient in the intestine.

The tablets are usually a reddish-orange colour and round in shape.

The quantity of tablets you are advised to use will be determined by your doctor or pharmacist, depending on your symptoms.

What are the side effects of Erythromycin 250mg Tablets?

Medicines can affect people differently. Side effects which have been commonly reported for Erythromycin 250mg Tablets include nausea and vomiting. You may also experience abdominal pain and diarrhoea.

Some individuals can experience allergic skin reactions (e.g. rashes, hives and/or itching).

Erythromycin can also affect your internal organs. It may disturb your liver function or cause inflammation of the liver (hepatitis) or pancreas (pancreatitis). You may also experience jaundice or an irregular heartbeat (arrhythmias).

If you take a large dose, you may have some hearing loss. However, this is usually reversible.

As with many other antibiotics, Erythromycin 250mg Tablets can cause inflammation of the bowel, also known as colitis. This can cause diarrhoea. If this symptom becomes severe or persistent, or you have accompanying blood or mucus, you should contact a doctor immediately.

An extended course of Erythromycin 250mg Tablets, or other antibiotics, can cause fungi or yeasts such as Candida to grow more rapidly, leading to infections such as oral or vaginal thrush.

Tell your doctor if you develop a new infection when taking this medicine.

What are the precautions/interactions of Erythromycin 250mg Tablets?

While both adults and children can use erythromycin safely, there are several individuals who should exercise caution when using this medication.

If you have liver or kidney problems, an abnormal heart rhythm or myasthenia gravis you should be aware of the possible side effects of taking Erythromycin 250mg Tablets. Those with porphyria, a hereditary blood disorder, must also be careful.

You should not use these tablets if you are allergic to any of the ingredients. If you experience an allergic reaction after taking an erythromycin tablet, stop taking this medicine immediately and consult your doctor.

Erythromycin is not thought to be harmful to pregnant women or unborn babies. It does pass through breast milk, but this does not usually result in side effects for the baby. However, to be safe you should look out for signs of diarrhoea, thrush or nappy rash in your baby.

You should not take any antacids two hours before or after taking erythromycin as they may dilute its effectiveness.

Erythromycin is known to have interactions with several medications. When taking erythromycin with any of the following, your risk of experiencing side effects increases:

  • amisulpride
  • astemizole
  • cisapride
  • domperidone
  • eletriptan
  • ergotamine
  • dihydroergotamine
  • dronedarone
  • ivabradine
  • lercanidipine
  • lomitapide
  • mizolastine
  • pimozide
  • quetiapine
  • rilpivirine
  • saquinavir
  • sertindole
  • simeprevir
  • simvastatin
  • terfenadine
  • tolterodine
  • vinblastine

Erythromycin also prevents the following medicines from breaking down properly, therefore increasing the risk of their side effects:

  • alfentanil
  • alprazolam
  • axitinib
  • avanafil
  • bedaquiline
  • bosutinib
  • bromocriptine
  • buspirone
  • cabergoline
  • cabozantinib
  • carbamazepine
  • ciclosporin
  • cilostazol
  • clozapine
  • colchicine
  • dapoxetine
  • darifenacin
  • dasatinib
  • digoxin
  • disopyramide
  • eplerenone
  • everolimus
  • felodipine
  • galantamine
  • ibrutinib
  • ivacaftor
  • laurasidone
  • methylprednisolone and other corticosteroids
  • midazolam
  • phenytoin
  • pravastatin
  • quetiapine
  • reboxetine
  • rifabutin
  • rupatadine
  • sildenafil
  • sirolimus
  • tacrolimus
  • tadalafil
  • theophylline
  • triazolam
  • ulipristal
  • valproate
  • vardenafil
  • verapamil
  • zopiclone

Erythromycin has been known to increase the effects of anticoagulants such as nicoumalone and warfarin. This increases the risk of bleeding, especially among elderly people.

When taken with statins which lower cholesterol, erythromycin can cause issues for the muscles and result in myopathy. You may wish to stop taking statins for your course of treatment, but it's best to consult your doctor before you do.

Cimetidine and protease inhibitors increase the blood level of erythromycin. This therefore increases the risk of side effects.

If you take the oral typhoid vaccine 'Vivotif' during your course of erythromycin treatment, it may not be as effective. You should therefore wait three days after the treatment has ended before doing so.

Erythromycin 250mg Tablets do not affect the contraceptive pill. However, if you experience vomiting or diarrhoea as a side effect, follow the instructions on the accompanying leaflet for your contraceptive medication.

Erythromycin can interact with other medications, so seek medical advice from your pharmacist or doctor if you are taking any other medication including over-the-counter medicines and herbal remedies before using these tablets.
