Althrocin 250mg (Erythromycin) – Uses, Dosage, Side Effects & Safety
Althrocin 250mg (Erythromycin) is a macrolide antibiotic widely used to treat a broad spectrum of bacterial infections. It is commonly prescribed for respiratory tract infections, throat infections, skin and soft tissue infections, some eye infections and selected sexually transmitted infections. Althrocin acts by preventing bacterial protein synthesis, which stops bacteria from growing and lets your immune system clear the infection more effectively.
Althrocin 250mg (Erythromycin)
Althrocin 250mg (Erythromycin) is produced by reputable manufacturers and is available in tablet form for oral administration. This product is often chosen for people who are allergic to penicillin or when a macrolide is clinically recommended. The 250 mg strength is commonly used in adult dosing schedules for milder to moderate infections; dosage and duration will always depend on the infection type and clinical guidance.
Product introduction
Erythromycin belongs to the macrolide class of antibiotics. It has a long history of safe and effective use against Gram-positive organisms and selected Gram-negative bacteria. Althrocin is typically prescribed for conditions such as bronchitis, community-acquired pneumonia, streptococcal throat infections, skin infections like impetigo or cellulitis (superficial), otitis media (middle ear infection), and some ocular infections when topical treatment isn’t suitable.
Its oral tablet form makes it convenient for outpatient treatment and for patients requiring short courses of therapy at home. The medication is usually well tolerated and is often administered with food to reduce the chance of stomach upset.
Uses of Althrocin 250mg (Erythromycin)
Althrocin 250mg is commonly used for the following indications (clinician-determined):
- Upper respiratory tract infections: pharyngitis, tonsillitis and sinusitis
- Lower respiratory tract infections: bronchitis and some community-acquired pneumonias
- Skin and soft tissue infections: impetigo, mild cellulitis, infected cuts
- Ear infections: otitis media
- Eye infections: bacterial conjunctivitis (systemic therapy where indicated)
- Certain sexually transmitted infections, when in line with local guidelines
- Dental infections and prophylaxis in certain dental procedures, as directed
Note: Use is determined by the prescriber based on culture results, local resistance patterns and patient-specific factors.
Benefits of Althrocin 250mg (Erythromycin)
When used appropriately, Althrocin provides several benefits:
- Broad spectrum activity against many common bacteria causing respiratory and skin infections.
- Suitable alternative for patients with penicillin allergy.
- Generally well tolerated with an established safety profile.
- Ease of oral dosing for outpatient management saves hospital visits.
- Rapid reduction of symptoms such as sore throat, fever, cough and local inflammation when infection is bacterial.
In Treatment of Worm infections
Important: Erythromycin is an antibiotic active against bacteria and is not a treatment for helminth (worm) infections. If worms or helminths are suspected, appropriate anthelmintic drugs (albendazole, mebendazole, praziquantel, etc.) should be used based on diagnosis. This heading is included to match the page structure but clinically erythromycin does not treat parasitic worms.
Side effects of Althrocin 250mg (Erythromycin)
Like all medicines, Althrocin can cause adverse effects. Many people experience no or only mild side effects; serious reactions are uncommon but possible.
Common side effects of Althrocin 250mg (Erythromycin)
- Nausea and vomiting
- Abdominal cramps and dyspepsia
- Diarrhoea — usually mild; if severe or persistent seek medical advice
- Loss of appetite
- Mild skin rash or irritation
Serious (rare) side effects: cholestatic hepatitis, severe allergic reactions (anaphylaxis), QT prolongation and cardiac arrhythmias in susceptible individuals, Clostridioides difficile associated diarrhoea (severe colitis). If you develop jaundice, severe abdominal pain, breathing difficulty, high fever, bloody diarrhoea, or fainting, seek urgent medical care.
How to use Althrocin 250mg (Erythromycin)
Always follow the prescribing doctor’s instructions and the product leaflet. General guidance:
- Swallow tablets whole with a glass of water.
- Take at evenly spaced intervals as directed; common regimens include 250 mg four times daily or 500 mg twice daily depending on indication — follow your prescriber.
- Taking with food may reduce stomach upset though absorption can be marginally delayed.
- Complete the entire prescribed course even if you feel better earlier — stopping early can lead to relapse or resistance.
- Do not self-adjust dose or duration without consulting your healthcare provider.
How Althrocin 250mg (Erythromycin) works
Erythromycin binds to the 50S subunit of bacterial ribosomes, inhibiting translocation during protein synthesis. This action prevents production of essential bacterial proteins, which inhibits growth (bacteriostatic) and ultimately leads to clearance of the infection by the immune system. Its mechanism differs from penicillins, hence it’s useful where beta-lactams are unsuitable.
Safety advice
| Allergy | Do not use if you have a known allergy to erythromycin or other macrolides. |
| Pregnancy | Discuss with your clinician — erythromycin is often considered when benefits outweigh risks; some formulations are preferred. Follow prescriber’s advice. |
| Breastfeeding | Small amounts pass into breastmilk. Consult your doctor before use. |
| Cardiac disease | Use with caution if you have known QT prolongation, electrolyte imbalances, or are taking other QT-prolonging drugs. |
| Liver impairment | Monitor liver function if you have significant hepatic disease. |
| Drug interactions | Erythromycin interacts with many drugs (statins, some anticoagulants, antiarrhythmics, certain anticonvulsants). Always tell your prescriber about other medicines you take. |
What if you forget to take Althrocin 250mg?
If you miss a dose, take it as soon as you remember. If it is nearly time for the next dose, skip the missed dose — do not double doses. If you miss several doses or are unsure, contact your healthcare provider for guidance. For infections, maintaining consistent dosing helps ensure success and prevents resistance.
All substitutes
Where erythromycin is unsuitable or unavailable, clinicians may choose alternative macrolide or other classes depending on infection and susceptibility. Possible alternatives include:
- Azithromycin (macrolide) — different dosing, often better tolerated
- Clarithromycin (macrolide) — similar spectrum, different drug interactions
- Doxycycline (tetracycline) — where indicated
- Benzylpenicillin or amoxicillin (beta-lactams) — where not allergic and susceptible
Always use the alternative recommended by your prescriber based on culture & sensitivity and clinical situation.
Quick tips
- Inform your prescriber of all medications and supplements you use.
- Avoid grapefruit juice with some macrolides where advised (clarithromycin interaction — not typically erythromycin, but check local guidance).
- Store tablets in a cool, dry place away from children.
- Report severe side effects immediately (jaundice, severe rash, breathing problems, severe diarrhoea).

Patient concerns
Will erythromycin cure my throat infection quickly? Many patients notice symptomatic relief within 48–72 hours, but complete the prescribed course. If symptoms worsen or fail to improve, contact your prescriber for reassessment.
Is it safe for children? Erythromycin is used in children under clinician supervision; dosing is weight/age-based. Do not administer adult tablets to young children unless directed.

FAQs
Can Althrocin 250mg (Erythromycin) be stopped when my symptoms are gone?
No. You should complete the full prescribed course unless advised otherwise by your prescriber. Stopping early may allow bacteria to persist and increase antibiotic resistance risk.
Can the use of Althrocin cause diarrhoea?
Yes — mild diarrhoea is a common side effect. If diarrhoea is severe or contains blood, seek medical attention as it could indicate a more serious infection such as C. difficile colitis.
Will Althrocin 250mg be more effective if taken in more than recommended dose?
No. Increasing dose without clinical direction raises risk of toxicity and side effects (including cardiac effects) and does not reliably improve outcomes.
What are the instructions for storage and disposal of Althrocin 250mg?
Store in the original container at room temperature away from moisture and direct sunlight. Keep out of reach of children. Return unused medicines to a pharmacy for proper disposal rather than discarding in household waste.
