Ingredients in metronidazole?

Metronidazole products vary by formulation (tablet, capsule, vaginal gel/cream, IV infusion, etc.). So the “ingredients” can mean either the active drug or the full list of excipients (inactive ingredients).

Active ingredient

• Metronidazole (the medication itself)

Common inactive ingredients (examples, depend on brand/form)

Tablets/capsules may contain things like:

• Lactose (in some brands)
• Microcrystalline cellulose
• Starch
• Povidone
• Magnesium stearate
• Sodium starch glycolate (sometimes, as a disintegrant)
• Colloidal silicon dioxide
• Film-coating materials (hypromellose, titanium dioxide, etc.), depending on the product

Vaginal gels/creams may include:

• Carbomer/carbopol
• Glycerin or propylene glycol
• Water/propylene glycol
• Emulsifiers/thickeners
• Preservatives (varies)

IV infusion may include:

• Sodium chloride and/or sterile water (and sometimes buffering agents)

To give you the exact ingredient list

Tell me:

1. the dosage form (tablet, capsule, gel, cream, IV),
2. the strength (e.g., 500 mg, 250 mg), and
3. the brand name (and country if possible).

If you paste the label or “inactive ingredients” section from the package insert, I can break it down for you.
