Product information

Bettamousse is a treatment for skin conditions affecting the scalp, such as psoriasis, and is made by Pharmasol. It contains a type of agent called a corticosteroid, which is effective at reducing inflammation and relieving other symptoms. The treatment is a mousse, or foam, which in most cases is applied to the region affected twice daily, but this may be different in cases where symptoms are mild.

  1. For use on the scalp
  2. Gets to work on psoriasis quickly
  3. Simple to use

Psoriasis can occur anywhere on the body, but the scalp is one of the more common problem areas. Symptoms include inflammation leading to irritation, redness and itching, and it will usually result in scaly patches of skin and excess shedding. Pustules can also occur in more severe instances. Approximately two per cent of the UK population is affected, with the condition presenting itself for the first time usually prior to the age of 35.

The chronic nature of symptoms means that it is a condition which will return on a recurring basis. Several triggers have been identified, but these are not the same for everybody. Some people find that a flare-up can be brought on by stress, whereas others may find that smoking or excessive alcohol consumption may induce irritation. In other cases, a reaction to medication or changes in hormone levels can also be the principal instigator of a reactivation.

It isn’t fully understood why the condition occurs, but it is thought to be an autoimmune problem. When the immune system perceives a threat, which may not necessarily be present in those with psoriasis, it reacts by releasing a defensive chemical which attacks skin cells. This causes replacement cells to generate at an accelerated rate, leading to the above symptoms.

Prevention techniques for those living with the condition include avoiding likely triggers, however this is not always possible, and treatment may be required. Bettamousse is a foam which can be applied to treat those eruptions on the scalp, and is only available to buy in the UK on prescription. It contains a corticosteroid agent which works in the body to limit the activity of chemicals which can cause inflammation and redness to occur.

To buy this item, you will first need to be assessed by a doctor. This is so that they can ensure the treatment is suitable for you.

Presently, we do not offer this medication through our online service. Make an appointment with your GP if you are seeking treatment for psoriasis.

When using this medication, make sure you adhere to the instructions given by your prescriber, and that you familiarise yourself with the guidelines in the leaflet beforehand. This will help you to limit the risk of associated side effects and get the most out of the treatment.

  1. Administer as prescribed.
  2. This will in most cases be a twice daily application to the scalp but may vary depending on the severity of symptoms.
  3. It should only be used on the scalp.
  4. Wash your hands before and after use.
  5. Remove the cap.
  6. Squirt a golf ball-sized amount of mousse onto a clean saucer or holding surface. It is important not to squeeze it directly onto your hand, as it begins to dissolve on contact with the skin.
  7. Transfer the mousse onto the head and rub into the scalp.
  8. Permit the hair to dry naturally, and do not wash it after application. The mousse should be left in to work over the course of the day, or night if applying before bedtime.
  9. Do not exceed the prescribed dose.
  10. If you forget to use it, simply skip the dose you have missed and take it at the next appropriate time.
