When using ketoconazole 2% (Nizoral) shampoo or cream, you should avoid certain products and practices that may irritate your skin or reduce the effectiveness of treatment.
What should you avoid?
1. Avoid using it too frequently. Using ketoconazole more often than recommended can cause dryness, redness, itching, or burning. Daily use is appropriate for some fungal infections, but not routinely for dandruff.
2. Avoid contact with your eyes and mouth. Ketoconazole is intended for external use only. If it gets into your eyes, rinse thoroughly with water.
3. Avoid applying it to broken or severely irritated skin. Consult your healthcare provider before using it on cuts, open wounds, or inflamed skin.
4. Avoid harsh skincare products. Alcohol-based products, strong exfoliants, and heavily fragranced soaps may increase irritation when applied to the same area.
5. Avoid applying multiple medicated products simultaneously. If using ketoconazole cream with other creams or lotions, separate applications by approximately 30 minutes unless your healthcare provider advises otherwise.
6. Avoid scratching infected areas. Scratching may damage the skin and potentially spread the infection.
7. Avoid stopping treatment too early. Even if itching or redness improves, complete the recommended treatment course to reduce the chance of recurrence.
8. Avoid sharing towels and clothing. Some fungal skin infections can spread through contaminated personal items.

For ketoconazole 2% shampoo, generally leave the lather on the affected area for 3–5 minutes before rinsing thoroughly. Follow your specific product instructions.
Can you drink alcohol or go into the sun?
-
Alcohol: You generally do not need to avoid drinking alcohol while using topical ketoconazole shampoo or cream.
-
Sun exposure: Normal sun exposure is not prohibited, but protect irritated skin from excessive sunlight.
-
Other medications: Tell your healthcare provider if you're using topical steroids or other medicated skin products.
Stop using ketoconazole and seek medical advice if you develop severe irritation or an allergic reaction. Difficulty breathing or swelling of the face or throat requires emergency care.
