Azithromycin Interactions:

A drug can interact with any other medicine that you are taking and show some unwanted effects or desired effect will be diminished. Azithromycin can interact with various medications, vitamins or any herbal medication you are taking and hence, it is advisable to discuss with your doctor about the drug details before taking it.

Some medicines can cause serious interactions and may need medical attention, like:

  • Nelfinavir: If you take Azithromycin with this, you may notice liver or hearing problems.
  • Warfarin: This combination may lead to increased bleeding.

Consumption of this drug with mild alcohol will not show any serious side-effects but moderate to high alcohol intake may increase the side-effects.


Just like every other drug, this medicine also has its own side-effects which are as follows:

  • Nausea, vomiting.

  • Diarrhea.

  • Pain in the abdomen.

  • Dizziness.

  • A headache.

These are milder forms of unwanted effects and may go within some time. There are some serious side effects that require stoppage of the medicine and immediate medical attention, and they are as follows:

  • Liver issues which can show symptoms like weakness, fatigue, upper abdominal pain, yellow discoloration of the skin and mucous membrane, dark urine.

  • Irregular rhythm of the heart.

  • Pregnancy and breastfeeding: The drug can pass through breast-milk. Hence, it is necessary to talk to your gynecologist before consuming the drug in case of both pregnancy and breastfeeding.

In case of overdose, contact the emergency medical team for immediate medical help. Inappropriate usage of this drug will lead to the development of drug resistance to the bacteria, hence should not be used without physician’s advice.
