Dyes in Medications: What They Are & Why They’re Used
Many medications contain color additives, often referred to as dyes.

Why Are Dyes Added to Medications?
Dyes are commonly used to:
- Differentiate strengths or dosages
- Identify medications visually
- Improve consistency in appearance
- Prevent confusion between similar products
Coloring is especially common in tablets and capsules.
