Ingredients in azithromycin?

Azithromycin isn’t a single ingredient—it's usually azithromycin (the active ingredient) plus inactive (inactive) ingredients that vary by brand and dosage form (tablet, capsule, oral suspension, etc.).

Common active ingredient

• Azithromycin (as azithromycin dihydrate, azithromycin monohydrate, etc., depending on the product)

Common inactive ingredients (vary by product)

These can include, depending on whether it’s a tablet/capsule or liquid:

• Microcrystalline cellulose
• Starch (e.g., pregelatinized starch/corn starch)
• Lactose (in some tablets)
• Magnesium stearate
• Sodium starch glycolate (for tablets as a disintegrant)
• Cellulose derivatives (e.g., hypromellose), talc
• Colorants/ink ingredients for tablets/capsules
• For oral suspension, often:
  • Sucrose or other sweeteners
  • Xanthan gum or similar thickener
  • Citric acid
  • Flavorings
  • Purified water

If you tell me the exact product, I can be precise

What does your label say (e.g., Zithromax 250 mg tablets, azithromycin 100 mg/5 mL suspension, etc.) and the manufacturer if listed? Then I can list the specific inactive ingredients for that formulation.
