Zathrin 100 DT Tablet is used for treatment of Bacterial infections.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Zathrin 100 DT Tablet contains Azithromycin (100mg). It belongs to the Macrolide class of medicines.
Treatment of Bacterial infections
Zathrin 100 DT Tablet is an antibiotic. It works by interfering with the synthesis of essential proteins required by bacteria to perform important functions. By doing so, it stops the infection-causing bacteria from growing further and prevents the infection from spreading.
Swallow the tablet whole with a glass of water. Do not chew, crush or break it unless your doctor has told you to. Take it with or just after food. Taking it at about the same time each day helps you remember. Follow the dose and the duration written on your prescription.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
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 Zathrin 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 | Consult your doctor before using this in pregnancy. |
|---|---|
| Breastfeeding | Consult your doctor before using this while breastfeeding. |
| Alcohol | Alcohol may worsen the side effects of this medicine. Limit it. |
| Driving | Not expected to affect your ability to drive. |
| Kidney | Kidney CAUTION |

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.
Your child must complete the entire course of this medicine. Stopping too soon may cause the bacteria to multiply again, become resistant, or cause another infection. Give Zathrin 100 DT Tablet with food to avoid an upset stomach. Encourage your child to drink plenty of water in case diarrhea develops as a side effect. Zathrin 100 DT Tablet will not be effective for viral infections. However, the doctor may prescribe this medicine in case of a secondary bacterial infection. So make sure to speak to your child’s doctor first. Only give Zathrin 100 DT Tablet to your child for their current infection. Never save medicine for future illnesses. Stop the medicine and contact the doctor immediately if your child develops an itchy rash, facial swelling, and breathing difficulties soon after the intake.
