Red Dye No. 3: What ingredient did the FDA just ban?

4 min read

In early 2025, the U.S. Food and Drug Administration (FDA) announced a long-awaited and historic ban on a decades-old additive. The answer to the question, What ingredient did the FDA just ban?, is Red Dye No. 3, a color additive that will no longer be permitted in ingested medications or foods after its regulatory phase-out is complete.

Quick Summary

The FDA has banned Red Dye No. 3, a color additive, from all ingested food and drugs, citing animal studies that linked it to cancer. Manufacturers have until January 2027 to reformulate products, marking a major update to food and drug safety regulations.

Key Points

  • FDA Bans Red Dye No. 3: In early 2025, the FDA finalized a ban on the color additive Red Dye No. 3 from all ingested food, drinks, and drugs.

  • Carcinogenicity in Animal Studies: The ban was based on animal studies from the 1980s that linked the dye to thyroid cancer in male rats.

  • Two-Year Phase-Out Period: Manufacturers have until January 2027 to reformulate products, so items containing Red 3 may still be available during the transition.

  • Check Medication Labels: The dye is listed in the 'inactive ingredients' section of drug labels, and consumers can look for "Red 3" or "FD&C Red #3".

  • Separate from Phenylephrine Action: This ban is distinct from the FDA's proposed removal of the oral decongestant phenylephrine, which was due to a lack of effectiveness, not safety.

  • Alternatives are Available: For both food and medicine, manufacturers can use other dyes, including natural alternatives like beet juice and carmine.

The FDA’s Final Rule on Red Dye No. 3

After decades of regulatory inaction, the FDA issued a final order to ban FD&C Red No. 3, also known as Red 3, from all ingested food and drug products. The ban was the culmination of pressure from consumer advocacy groups and follows similar state-level legislation in places like California. This decision ends a prolonged period of regulatory paradox where the dye had been deemed unsafe for topical use but remained legal in products people consume.

The Carcinogenicity Finding and Regulatory History

The ban on Red Dye No. 3 is rooted in animal studies from the 1980s that demonstrated a link between the additive and thyroid cancer in male rats. Under federal law, the FDA is required to prohibit any ingested color additive that causes cancer in animals or humans, a provision known as the Delaney Clause. While the FDA banned Red 3 in cosmetics and topical drugs in 1990 based on this evidence, it failed for over three decades to extend the prohibition to food and oral drug products. The final action in early 2025 rectifies this long-standing discrepancy, aligning federal regulation with the agency's own safety mandate.

Impact on Ingested Medications and Consumers

The ban applies to any ingested medicine containing FD&C Red No. 3, which is often listed in the 'inactive ingredients' section of drug labels. Many over-the-counter (OTC) medications used to treat colds, flu, and allergies may be affected, particularly those formulated as brightly colored tablets or liquids.

This regulatory change means:

  • Reformulation is Required: Drug manufacturers have been given a timeline, with a final compliance date of January 2027, to remove Red Dye No. 3 from their products.
  • Check Labels: Until the deadline, consumers should check the ingredient lists for "Red 3" or "FD&C Red #3" if they wish to avoid the additive.
  • Consult Your Pharmacist: Healthcare providers can assist consumers in finding dye-free or reformulated alternatives to their current medications.

Implications for the Food Industry

The ban also has a significant impact on the food and beverage industry, where Red Dye No. 3 was a common ingredient in many products. These included seasonal candies, fruit cocktails, and maraschino cherries. While many companies have already phased out the use of Red 3, the ban ensures all manufacturers will comply. Alternatives being adopted include naturally derived colorants like beet juice, carmine, and pigments from fruits and vegetables.

Alternatives and Consumer Options

For consumers concerned about color additives, several alternatives are available, both in the food and medication sectors:

  • Dye-Free Formulations: Many drug brands now offer dye-free or naturally colored versions of their products.
  • Alternative Colorants: Manufacturers can and do use alternative artificial dyes, though some, like Red 40, face separate controversies and state-level bans.
  • Dietary Choices: Avoiding ultra-processed foods and beverages is another way to significantly reduce consumption of synthetic dyes.

A Broader Context: Comparison with Oral Phenylephrine

This ban on Red Dye No. 3 is not the only recent FDA action concerning OTC medications. Another significant development pertains to the oral decongestant phenylephrine. The FDA's Nonprescription Drug Advisory Committee concluded in September 2023 that oral phenylephrine is ineffective at the recommended dosage, finding it works no better than a placebo. Following this, in November 2024, the FDA issued a proposed order to remove oral phenylephrine from OTC products, with a final decision expected in 2026. This action, however, was based on a lack of efficacy rather than safety concerns, and it does not affect phenylephrine nasal sprays, which remain effective.

Comparing Regulatory Actions: Red Dye No. 3 vs. Oral Phenylephrine

Feature Red Dye No. 3 Ban Oral Phenylephrine Proposed Ban
Reason for Action Carcinogenicity concerns based on animal studies. Lack of evidence of efficacy at recommended dosage.
Regulatory Status Finalized ban on all ingested products in early 2025. Proposed ban announced in November 2024; final order pending public comments.
Timeline for Compliance Manufacturers have until January 2027 to reformulate products. Enforcement expected no sooner than late 2026, pending final order.
Scope of Ban Affects all ingested foods, drinks, and drugs. Affects only oral, ingested forms of the drug (e.g., pills, syrups).
Impact on Safety Action taken based on potential health risk (carcinogen). Action based on ineffectiveness; no new safety concerns identified.
Affected Products Seasonally colored candies, maraschino cherries, some medications. Many popular OTC cold and allergy medications like Sudafed PE and DayQuil.

Conclusion

The FDA's decision to ban Red Dye No. 3 from ingested drugs and foods is a landmark moment in food and drug safety regulation, finally addressing a decades-old health concern. While the phase-out period provides a gradual transition, it signals a renewed commitment to consumer protection and underscores the importance of ongoing review of inactive ingredients. This action, alongside the proposed removal of oral phenylephrine, highlights the dynamic nature of regulatory science and the mechanisms in place to ensure medications are both safe and effective for public use. Consumers should remain vigilant by reading ingredient labels and consulting healthcare professionals to stay informed about the products they use.
