Managing Vaniqa Side Effects
For Acne
- Use non-comedogenic moisturisers
- Apply Vaniqa after acne treatments (e.g., benzoyl peroxide)
- Consult your GP for topical antibiotics if persistent
For Skin Irritation
- Reduce application to once daily until tolerance improves
- Apply a fragrance-free moisturiser 30 minutes after Vaniqa
- Avoid alcohol-based skincare products
When to Discontinue
Stop Vaniqa and consult a doctor if:
- Side effects worsen after 2 weeks
- You develop sores or severe rash
- Eye irritation occurs (Vaniqa isn't for periorbital use)
Frequently Asked Questions
Are Vaniqa side effects worse than laser hair removal?
Vaniqa typically causes milder but more frequent side effects (acne, irritation) versus laser (temporary redness/swelling). Laser risks include burns or pigment changes in dark skin.
Can I use makeup if Vaniqa irritates my skin?
Yes, but wait 5 minutes after applying Vaniqa. Choose mineral-based, non-comedogenic products to avoid clogging pores.
Does Vaniqa cause long-term skin damage?
No studies show permanent damage. Any irritation typically resolves within 4 weeks of stopping treatment.
Why does Vaniqa cause acne?
Eflornithine may temporarily increase skin cell turnover, trapping oil in pores. This usually improves as skin adjusts.
Can men experience different side effects?
Vaniqa isn't licensed for men. Off-label use may cause worse irritation due to thicker facial skin and denser hair follicles.
