Frequently asked questions
Is Selsun shampoo still available in the UK?
No. Selsun 2.5% medicated shampoo was discontinued by its manufacturer in September 2022 and is no longer supplied as a UK medicine. Nizoral 2% remains available and treats dandruff and seborrhoeic dermatitis – the same scalp conditions treated by Selsun – using a different active ingredient.
Why was Selsun discontinued?
Selsun 2.5% was discontinued by its manufacturer in September 2022. It was not an MHRA safety recall. If you used Selsun for dandruff or seborrhoeic dermatitis, Nizoral 2% is an available UK treatment for the same conditions.
Is Nizoral the same as Selsun?
No. Selsun contained selenium sulfide 2.5%, whereas Nizoral contains ketoconazole 2%. They are different but both treat dandruff and seborrhoeic dermatitis.
Can I use Nizoral instead of Selsun?
Yes – if you used Selsun for dandruff or seborrhoeic dermatitis, Nizoral 2% is a suitable UK treatment option for many people because it is licensed for the same conditions. If you are unsure what is causing your scalp symptoms, ask a pharmacist or doctor.
What does Nizoral 2% shampoo treat?
Nizoral 2% treats and helps prevent dandruff and seborrhoeic dermatitis – the same conditions Selsun was used to treat. These conditions can cause scalp flaking, itching and redness.
How does Nizoral work?
Nizoral contains ketoconazole 2%, an antifungal medicine that targets Malassezia yeast associated with dandruff and seborrhoeic dermatitis. Controlling this yeast helps reduce the flaking, itching and redness caused by these conditions.
How do I use Nizoral shampoo?
Wet the hair and scalp, apply a small amount and massage it into a lather. Leave it on for 3 to 5 minutes, then rinse thoroughly. Avoid contact with the eyes and mouth, and follow the leaflet supplied with your pack.
How often should I use Nizoral for dandruff?
Use it twice a week for 2 to 4 weeks. Once symptoms have cleared, it can be used once every 1 to 2 weeks to help prevent them returning. Do not use it more often than directed.
How long does Nizoral take to work?
Symptoms may start to improve within 2 to 3 weeks, but complete the recommended 2-to-4-week treatment course. Speak to a pharmacist or doctor if symptoms are worsening or have not cleared after 4 weeks.
Can I use Nizoral every day?
Not for the usual treatment of dandruff or seborrhoeic dermatitis. Use it twice weekly for 2 to 4 weeks, followed by once every 1 to 2 weeks for prevention if needed.
Can children use Nizoral shampoo?
Most adults and children aged 12 years and over can use ketoconazole shampoo. Ask a pharmacist or doctor before using it for a child under 12.
Can I use Nizoral during pregnancy or while breastfeeding?
NHS guidance says ketoconazole shampoo can be used during pregnancy and breastfeeding because only tiny amounts are absorbed. Tell your pharmacist or doctor if you are pregnant, trying to conceive or breastfeeding if you have any concerns.
What side effects can Nizoral shampoo cause?
Side effects are uncommon when used correctly, but irritation, itching, burning or redness can occur. Stop using it and seek advice if irritation is severe, spreads or does not improve. Seek urgent help for signs of a serious allergic reaction.
Does Nizoral treat hair loss?
No. Nizoral 2% shampoo is not licensed as a treatment for hair loss.Â
