What is Eromycin?

Eromycin 150 mg/5 ml lotion, produced by Square Pharmaceuticals PLC, Pabna, contains the macrolide antibiotic erythromycin. It is a long-trusted antibiotic used to treat many bacterial infections and is a useful alternative for people who are allergic to penicillin.

Erythromycin works by attaching to the bacteria's ribosomes — the tiny factories where they build proteins. By blocking this protein-making process, the medicine stops the bacteria from growing and multiplying, allowing the body's immune system to clear the infection. It is mainly active against many common chest, skin and throat bacteria.

Indications

Doctors prescribe Erythromycin for a range of infections caused by sensitive bacteria, such as:

  • Chest and respiratory infections — bronchitis, pneumonia and whooping cough
  • Throat, tonsil and ear infections
  • Skin and soft-tissue infections, including acne in some cases
  • Dental and sinus infections
  • Some sexually transmitted infections and eye infections

It is especially useful for patients who cannot take penicillin. Your doctor will confirm whether erythromycin is suitable for your particular infection.

Dosage & Administration

The dose of Eromycin depends on the type and severity of infection, your age and weight. The details below are a general guide only.

  • Adults: a typical course lasts 5 to 14 days, with doses usually taken every 6 to 12 hours.
  • Children: the dose is based on body weight and must be decided by a doctor, often using the suspension form.

Take Eromycin with a glass of water. Taking it with or just after food can reduce stomach upset. Space your doses evenly and complete the whole course, even if you start feeling better.

Side Effects

Stomach-related effects are the most common with Erythromycin:

  • Common: nausea, vomiting, stomach cramps, diarrhoea and loss of appetite
  • Less common: skin rash, itching and a temporary change in taste
  • Serious (seek urgent help): severe diarrhoea, yellowing of the skin or eyes, irregular or fast heartbeat, fainting, or a severe allergic reaction with swelling and breathing difficulty

The stomach effects are often milder if you take the medicine with food. Tell your doctor if side effects are severe or do not settle.

Precautions & Warnings

Erythromycin is a prescription-only antibiotic. Take it only when a registered doctor prescribes it for you — never self-medicate, share it, or keep leftovers for another illness.

  • Finish the entire course even if you feel well after a few doses. Stopping early allows hardy bacteria to survive and return.
  • Antibiotic resistance is a serious and worsening problem in Bangladesh. Every unnecessary or incomplete antibiotic course makes future infections harder to cure.
  • Tell your doctor if you have liver problems, a heart-rhythm condition, or a history of long QT.
  • Inform the doctor of all other medicines, as erythromycin interacts with many drugs.

Drug Interactions

Erythromycin can change how many other medicines behave. Always give your doctor a full list of what you take. Important interactions include:

  • Statins (such as simvastatin) — higher risk of muscle damage
  • Warfarin — increased bleeding risk
  • Theophylline, carbamazepine and digoxin — raised drug levels
  • Drugs that affect heart rhythm (some antihistamines, antipsychotics)
  • Ergot medicines for migraine

Because of these interactions, never combine erythromycin with new medicines without checking with your doctor or pharmacist.

Contraindications

Do not take Erythromycin if you:

  • Are allergic to erythromycin or other macrolide antibiotics (such as azithromycin or clarithromycin)
  • Have a serious heart-rhythm problem or known long-QT syndrome
  • Have severe liver disease
  • Are taking medicines that must not be combined with it, such as certain statins or ergot drugs

Share your full medical and medicine history with your doctor before starting treatment.

Pregnancy & Lactation

Erythromycin has been used during pregnancy and is often considered one of the more acceptable antibiotics when treatment is genuinely needed, but it should still only be taken on a doctor's advice.

Small amounts pass into breast milk; it is usually regarded as compatible with breastfeeding, though the baby should be watched for tummy upset. If you are pregnant, planning a pregnancy or breastfeeding, tell your doctor before starting Eromycin so the safest choice can be made for you and your baby.

Storage Conditions

Store Eromycin in a cool, dry place below 30°C, away from heat, direct light and moisture.

  • Keep tablets in their original pack.
  • Reconstituted suspension may need refrigeration — follow the label and discard after the stated number of days.
  • Keep all medicines out of the reach of children.
  • Do not use past the expiry date; return unused medicine to a pharmacy.

Frequently Asked Questions

Is it okay to stop Eromycin when my symptoms improve?

<p><strong>No.</strong> Always complete the full course of Eromycin that your doctor prescribed, even if you feel better after two or three days. Some bacteria may still remain, and stopping early lets the strongest ones survive, multiply and come back harder to treat. This drives <strong>antibiotic resistance</strong>, a serious and growing danger in Bangladesh where many infections are becoming difficult to cure. Take each dose on time and finish the course unless your doctor specifically tells you to stop.</p>

Why does Eromycin upset my stomach, and how can I reduce it?

<p>Stomach upset — nausea, cramps and loose motions — is the most common side effect of erythromycin, because it can stimulate movement in the gut. Taking Eromycin with or just after food often makes these symptoms milder while still letting the medicine work. Eating small, regular meals and drinking water can also help. If the diarrhoea becomes severe, watery or bloody, or the upset stops you from taking your doses, contact your doctor rather than stopping on your own.</p>

Can I take Eromycin if I am allergic to penicillin?

<p>Often yes — erythromycin is a macrolide, a different family from penicillin, so it is a common alternative for people with penicillin allergy. However, you must still tell your doctor about your penicillin allergy and any other drug reactions before starting Eromycin. You should not take it if you are allergic to erythromycin itself or to other macrolides such as azithromycin. Your doctor will choose the antibiotic that is both effective and safe for you.</p>
