Althrocin 250 mg is used for treatment of Bacterial infections.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Althrocin 250 mg contains Erythromycin (250mg). It belongs to the Macrolide class of medicines.
Treatment of Bacterial infections
Althrocin 250 Tablet is an antibiotic. It works by inhibiting the production of key proteins that bacteria need to perform essential tasks. Thus, it stops the bacteria from growing and prevents the infection from spreading.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Althrocin 250 Tablet is to be taken on an empty stomach.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Althrocin 250 Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause vomiting, hearing disturbance and heart rhythm changes. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Althrocin are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.
| Pregnancy | Pregnancy CONSULT YOUR DOCTOR |
|---|---|
| Breastfeeding | Breast feeding CAUTION |
| Alcohol | Alcohol CONSULT YOUR DOCTOR |
| Driving | Driving CONSULT YOUR DOCTOR |
| Kidney | Kidney CAUTION |
| Liver | Liver CAUTION |
| Habit forming | No |
Finish the whole course even after you feel better. Tell your doctor if you have a heart rhythm problem or take a medicine for one — this group can affect the heart's electrical timing. Report severe or watery loose motions during or after the course rather than treating them yourself.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a known allergy to macrolide antibiotics, or with certain heart rhythm disorders.
Interacts with a long list of medicines, including statins, some heart medicines and blood thinners — tell your doctor everything you take. Antacids reduce absorption; separate them by a couple of hours.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Do not skip any doses and finish the full course of treatment even if you feel better. Stopping early may allow the infection to return and make it more difficult to treat. Do not take antacids 2 hours before or after taking Althrocin 250 Tablet. Diarrhea may occur as a side effect, but it should stop when your course is complete. Inform your doctor if it doesn't stop or if you find blood in your stools. Stop taking Althrocin 250 Tablet and inform your doctor immediately if you develop an itchy rash, swelling of the face, throat, or tongue, or breathing difficulties while taking it.
