Althrocin 500mg (Erythromycin) – Affordable Ery Tab Alternative
Althrocin 500 mg is a delayed-release tablet and is an antibacterial medicine containing erythromycin base in an especially enteric-coated tablet. The coating of the tablet protects the antibiotic from the inactivating effects of gastric acidity and allows efficient absorption of the antibiotic in the small intestine. Althrocin is highly effective in treating a great variety of clinical infections, such as:
- Upper respiratory tract infections of a mild to moderate degree
- Mild to moderately severe lower respiratory infections
- Eye infection
- Ear infection
- Oral infections
- Respiratory tract infections
- Gastrointestinal infections
- Mild to moderate-severe skin and skin structure infections
Precautions with Erythromycin 500mg tablets
Some medicines can contribute to undesirable or dangerous effects when used with Erythromycin consumption. This medicine is contraindicated in patients taking tolterodine, amisulpride, mizolastine, terfenadine, cisapride, astemizole, simvastatin, or pimozide. The medication is contraindicated in patients taking ergotamine and dihydroergotamine.
The liver excretes this medication, so caution should be taken in using the antibiotic in patients with impaired insufficiency or concomitantly receiving medications that cause hepatotoxicity. There have been reports that Althrocin may cause worsening of the weakness of patients with myasthenia gravis. (a muscle problem).
Rhabdomyolysis (breakdown of skeletal muscle tissue) that causes kidney damage and other electrolyte imbalances have been reported in seriously ill patients receiving Erythromycin antibiotics.
Infants born to women treated with Althrocin at the time of pregnancy for early syphilis should be treated with appropriate penicillin therapy. Infantile hypertrophic pyloric stenosis (IHPS) may occur in infants receiving this antibiotic. This medicine can contribute to diarrhoea, which may be a symptom of a new infection. If you develop watery or bloody diarrhoea, discontinue treatment and seek medical help. In this case, anti-diarrheal medicine should be avoided unless advised by the healthcare provider.
Seek immediate medical help if you develop signs of an allergic reaction to Althrocin 500mg (trouble breathing, swelling in your face or throat, hives) or a severe skin reaction (sore throat, skin pain, burning eyes, fever, red or purple skin rash with peeling and blistering). Speak to your healthcare professional if you develop.
- A seizure
- Headache with severe dizziness, chest pain, fainting, and fast or pounding heartbeats.
- Hearing problems
- Severe stomach pain, watery or bloody diarrhoea (even if it occurs months after taking the last dose).
- Liver problems include tiredness, loss of appetite, easy bruising or bleeding, clay-coloured stools, upper right side pain in the abdomen, and jaundice (yellowing of the skin or eyes).
- Pancreatitis (inflammation of the pancreas)- nausea, vomiting, severe pain in your upper stomach that is spreading to your back.
Serious side effects of the medication may be more likely to occur in older adults. These include hearing loss or a life-threatening fast heart rate. Talk to your healthcare provider if a baby receiving this medicine is vomiting or irritable even while feeding.
Commonly reported side effects may include:
- Liver problems
- Abnormal liver function tests
- Severe stomach pain, watery or bloody diarrhoea, even if it occurs months after taking the last dose.
This is not a complete list of side effects, and there may be other side effects that occur. Seek medical advice about side effects.
Althrocin 500mg is taken orally, preferably an hour before or two hours after food. It is best absorbed when taken on an empty stomach. Avoid chewing, crushing, or breaking a delayed-release pill. Swallow the pill with a glass of water. It should be taken exactly as prescribed by your healthcare provider regularly at evenly spaced intervals.
It is recommended that the medicine be taken for the full prescribed length of time. In some cases, symptoms may improve before the infection is eliminated from the body. Stopping the medicine too early may contribute to the recurrence or worsening of the infection.
Note: Missing doses may increase your risk of developing further infections that are resistant to antibiotics. Althrocin will not treat a viral infection such as the common cold and flu.
What is Althrocin 500mg used for?
Althrocin 500mg contains erythromycin stearate 500mg — an oral macrolide antibiotic. It is used for: respiratory tract infections (community-acquired pneumonia — particularly atypical organisms: Mycoplasma pneumoniae, Legionella, Chlamydophila; streptococcal tonsillitis; whooping cough prophylaxis and treatment — erythromycin is a first-line for Bordetella pertussis); skin and soft tissue infections (impetigo, erysipelas, cellulitis — particularly in penicillin-allergic patients); sexually transmitted infections (non-gonococcal urethritis due to Chlamydia, lymphogranuloma venereum); intestinal amoebiasis (E. histolytica); dental infections (in penicillin-allergic patients); and acne vulgaris (oral use in special circumstances when other agents cannot be used).
How should Althrocin 500mg be taken?
Take Althrocin 500mg as prescribed — typically 500mg twice daily to four times daily depending on the infection. Erythromycin stearate: take on an empty stomach (1 hour before or 2 hours after meals) — food reduces absorption of erythromycin stearate. Take with a full glass of water. Duration: as prescribed for the specific infection (typically 7–14 days for respiratory infections; 5–7 days for skin infections; 14 days for chlamydia). Complete the full course — stopping early when symptoms resolve allows residual bacteria to survive and potentially cause relapse or resistance. Do not crush or chew enteric-coated tablets. Take at evenly spaced intervals to maintain consistent blood levels.
What drug interactions make Althrocin 500mg potentially dangerous?
Erythromycin is a significant CYP3A4 inhibitor and QT-prolonging agent — interactions are extensive. Contraindicated or high-risk combinations: pimozide, quinidine (fatal arrhythmias — QT prolongation); simvastatin, lovastatin (rhabdomyolysis — switch to pravastatin/rosuvastatin during erythromycin); ergot alkaloids (ergotism — severe vasoconstriction); colchicine (colchicine toxicity — particularly with renal impairment); cisapride (cardiac arrhythmia). Significantly increased levels requiring monitoring: warfarin (elevated INR — monitor closely); ciclosporin, tacrolimus (nephrotoxicity); carbamazepine (toxicity); digoxin (digitalis toxicity). Other QT-prolonging drugs: additive risk — antipsychotics, antiarrhythmics, some antidepressants. Always review all co-medications before erythromycin.
Is Althrocin 500mg safe in pregnancy?
Erythromycin base and erythromycin stearate are classified FDA Category B and are among the safer antibiotics in pregnancy. Erythromycin is commonly prescribed in pregnancy for: chlamydial infections (first-line alternative to azithromycin); streptococcal pharyngitis in penicillin-allergic pregnant women; pertussis prophylaxis and treatment. Important: erythromycin estolate salt should be avoided in pregnancy (hepatotoxicity risk) — erythromycin stearate (Althrocin) is the safer alternative. GI side effects (nausea) may be more pronounced in pregnancy. Dose: standard dosing applies. Erythromycin is NOT associated with major teratogenicity — evidence from large epidemiological studies is generally reassuring for brief antibiotic courses in pregnancy.
What are the GI side effects of Althrocin 500mg and how can they be managed?
GI side effects are the most common reason for erythromycin discontinuation — occurring in 20–30% of patients. Mechanisms: erythromycin is a motilin receptor agonist — stimulates gastric motility and intestinal smooth muscle, causing: nausea, vomiting, abdominal cramping, and diarrhoea (this prokinetic property is also exploited therapeutically for gastroparesis). Management: take with a small amount of food (despite reduced absorption — the tolerability benefit outweighs the modest pharmacokinetic effect for the stearate formulation); use antacids (separate by 2 hours from dose); reduce dose frequency if clinically tolerable; consider switching to azithromycin (same macrolide class — better GI tolerability, once-daily dosing) or clarithromycin if erythromycin GI intolerance prevents completion of the course.
How does Althrocin 500mg compare to azithromycin for respiratory infections?
Erythromycin 500mg and azithromycin 500mg are both macrolide antibiotics for atypical respiratory infections. Azithromycin advantages: once-daily dosing (better adherence); shorter course (3–5 days vs. 7–14 days for erythromycin); significantly fewer GI side effects; longer tissue half-life providing persistent concentrations after the last dose; fewer drug interactions (less potent CYP3A4 inhibitor). Erythromycin advantages: lower cost; longer clinical experience; first-line for pertussis (whooping cough) — equal efficacy; available as liquid suspension for children. Most current antibiotic guidelines prefer azithromycin over erythromycin for most macrolide indications due to superior tolerability, convenience, and compliance. Erythromycin is retained as: first-line for pertussis; alternative when azithromycin is unavailable; and first-line oral macrolide in penicillin-allergic patients in some resource settings.
Is Althrocin 500mg equivalent to Erythrocin or E-Mycin?
Yes. Althrocin 500mg and branded Erythrocin 500mg / E-Mycin 500mg all contain erythromycin stearate 500mg in equivalent oral tablet formulations. Althrocin is the generic alternative providing the same macrolide antibiotic therapy at significantly lower cost. PremiumRxDrugs.com stocks authentic manufacturer-sourced Althrocin 500mg verified for quality and bioequivalence.

Our genuine manufacturer-verified erythromycin tablets, competitive pricing, and free worldwide shipping on qualifying orders make us a reliable international pharmacy for oral macrolide antibiotic therapy.
What side effects does Althrocin 500mg cause?
Common (>10%): nausea, vomiting, abdominal pain, and diarrhoea (see GI discussion above). QT prolongation: erythromycin prolongs the cardiac QT interval — risk of life-threatening torsades de pointes arrhythmia particularly with IV use, pre-existing QT prolongation, or concurrent QT-prolonging drugs; avoid in patients with known prolonged QT, hypokalaemia, or hypomagnesaemia. Hepatotoxicity: cholestatic jaundice (more common with erythromycin estolate — less risk with stearate; avoid in pre-existing liver disease). Ototoxicity: high-dose or prolonged use can cause reversible hearing loss and tinnitus. Allergic reactions (rash, urticaria) — rarely anaphylaxis. Clostridium difficile colitis: rare with short courses but possible. Superinfection (candida vaginitis, oral thrush).
What is the role of erythromycin for whooping cough (pertussis) treatment?
Erythromycin remains the preferred antibiotic for Bordetella pertussis (whooping cough) treatment and post-exposure prophylaxis. Why erythromycin: it is the most studied macrolide for pertussis; reduces Bordetella carriage (bacterial eradication) within 5–7 days; reduces transmission to contacts when given to index cases. Treatment dose: erythromycin 500mg four times daily for 14 days (adults). Prophylaxis for household contacts: same dose and duration. Clinical caveat: erythromycin treatment reduces bacterial shedding and transmission, but does not significantly shorten the clinical course of the illness (coughing paroxysms) if started more than 1–2 weeks after symptom onset. Azithromycin (5-day course) and clarithromycin (7-day course) are acceptable alternatives with better GI tolerability — particularly important for young children who struggle with 14-day erythromycin courses.
What is the correct erythromycin dose for chlamydial infection treatment?
For uncomplicated urogenital Chlamydia trachomatis: erythromycin base or stearate 500mg four times daily for 7 days — or erythromycin ethylsuccinate 800mg four times daily for 7 days. This is the WHO/CDC-recommended alternative regimen when azithromycin (preferred — 1g single dose) or doxycycline (preferred — 100mg twice daily for 7 days) cannot be used (e.g., pregnancy: erythromycin preferred over doxycycline and azithromycin). Treatment success: erythromycin achieves approximately 80% cure for chlamydia (lower than azithromycin or doxycycline due to GI intolerance leading to incomplete course completion). Test of cure: recommended 3 weeks after erythromycin treatment in pregnancy to confirm chlamydia eradication. Partner notification and simultaneous treatment of sexual partners is essential.
