Management
of psoriasis with emollients only may
be adequate in mild or asymptomatic cases, as well as for maintenance between
exacerbations.

An emollient is important to lubricate skin at all times
- An emollient is important to lubricate skin at all times.
- The addition of a tar preparation may be appropriate in mild cases.
-
Alternatively, calcipotriol ointment should be used to a maximum of 100g per week in adults, due
to risk of hypercalcaemia.
20% of patients experience irritation, and for this reason the face and flexures
should be avoided.
- A moderately potent or potent steroid ointment may be added for patients intolerant of or unresponsive to calcipotriol alone. These should be used in an alternating am/pm or am/am regimen.

Dovobet
RPotent topical steroids carry the risk of destabilising psoriasis and side-effects from prolonged use – regular review is required by prescribers.
- Short contact dithranol may be useful if there are just a few large plaques.
- Clearance is deemed to have occurred when the skin is flat to the touch.
·
Itchy plaques - consider alternating tar
or calcipotriol with moderately
potent topical steroid
·
Hyperkeratotic
- salicylic
acid preparation, which is sometimes appropriate to combine with a topical
corticosteroid e.g. Diprosalic®, in combination with tar or calcipotriol
· Flexural - moderately potent topical steroid, often used in combination with anti-yeast and antibacterial preparations, eg Trimovate®.
· Guttate - emollient plus coal tar preparation. Consider referral for phototherapy if not settling after 6 weeks.
· Scalp
Application of olive or coconut oil to scalp, leave overnight to remove scale and wash out with tar-based shampoo T-gel® or Capasal®
If not itchy, use a descaling ointment such as Sebco®
If
hairline affected, use moderately potent topical steroid
· Refer to secondary care if:
fails to respond adequately to above
diagnostic uncertainty
>20% skin involved (to consider phototherapy or systemic therapy)
stubborn guttate (to consider phototherapy)
unstable
(pustular or fiery) psoriasis - emergency referral indicated
Phototherapy is now the treatment of choice for moderate to severe psoriasis. Ultraviolet light does not help all cases of psoriasis and treatment has to be carefully monitored. Sunbeds should not be used for treatment as they cannot be carefully monitored and importantly, are not an effective treatment whereas phototherapy (narrow-band UVB and PUVA) is highly effective.
