ACUTE

cutaneous disease

Back
1st line – 

topical or intralesional corticosteroid

In mild cases, potent topical corticosteroids are used as first-line therapy.[55]​​

Hypertrophic LP plaques may benefit from potent topical corticosteroids under occlusion or intralesional corticosteroids.

Tapering down topical corticosteroid strength/dosage at the earliest possible opportunity is important to avoid its cutaneous adverse effects. The risk of adrenal suppression is low unless LP is extensive.

Primary options

clobetasol topical: (0.05%) apply to the affected area(s) twice daily, maximum 50 g/week

OR

betamethasone dipropionate topical: (0.05%) apply to the affected area(s) once or twice daily

OR

triamcinolone acetonide: consult specialist for guidance on intralesional dose

Back
Consider – 

antihistamine

Treatment recommended for SOME patients in selected patient group

Consider using antihistamines as an adjunct to reduce itch.

Primary options

chlorpheniramine: 8 mg (extended-release) orally two to three times daily when required, maximum 24 mg/day

OR

diphenhydramine: 25-50 mg orally every 6-8 hours when required, maximum 300 mg/day

Back
Consider – 

topical antipruritic

Treatment recommended for SOME patients in selected patient group

Consider topical antipruritic agents (e.g., doxepin, menthol, camphor) as an adjunct treatment to reduce itch.[55]​ Various formulations of menthol and camphor are available without a prescription, and formulations vary.

Primary options

doxepin topical: (5%) apply to the affected area(s) four times daily (at least 3-4 hours apart) for up to a maximum of 8 days

Back
2nd line – 

oral corticosteroid or retinoid or phototherapy

Severe forms of the disease (i.e., with marked irritation, widespread guttate LP) may require treatment with systemic corticosteroids.[2][57] Treatment may be continued for 2 to 6 weeks and then gradually tapered over several weeks.

Systemic corticosteroids also remain a popular strategy for recalcitrant LP. Consultation with a specialist is recommended for dosing and treatment duration for longer term use.

Oral retinoids (e.g., acitretin) have been documented as an effective second-line therapy.[58]

Phototherapy (in the form of broad or narrowband UVB, oral, or bath photochemotherapy with psoralen [PUVA] and UVA1 phototherapy) can also be used as an effective second-line therapy.[59][60][61][62] Considering the potential adverse effects, UVB is often preferred over PUVA.

Consultation with a specialist is recommended before initiating systemic treatment.

Primary options

prednisone: 30-80 mg orally once daily for 4-6 weeks, then taper gradually according to response

Secondary options

acitretin: 20-35 mg orally once daily

Back

Consider – 

phototherapy added to oral corticosteroid or retinoid

Treatment recommended for SOME patients in selected patient group

Phototherapy (in the form of broad or narrowband UVB, oral or bath photochemotherapy with psoralen [PUVA] and UVA1 phototherapy) can be used as a treatment adjunct in patients not already being treated with phototherapy.[59][60][61][62] Considering the potential adverse effects, UVB is often preferred over PUVA.

Back
3rd line – 

immunosuppressant/immunomodulator

Numerous alternative treatment modalities exist, but evidence for these is limited.[63]

Oral cyclosporine is useful for inducing a remission in severe cases resistant to retinoids and systemic corticosteroid therapy.[64][65]​ However, long-term use is associated with renal toxicity and relapse of LP may occur on discontinuation.

Topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus) may also be considered, but data on efficacy for cutaneous LP are limited to case reports.[55][63]​ Because of the theoretical risk of potentiating malignant transformation, patients on topical calcineurin inhibitors need careful evaluation on follow-up.

Topical vitamin D analogues (e.g., calcipotriene) may be useful as an alternative to topical corticosteroids, but evidence is very low quality.[63]

Examples of other agents used in the treatment of severe cutaneous LP include antifungals (e.g., griseofulvin), antibiotics (e.g., metronidazole), sulfasalazine, hydroxychloroquine, low-molecular-weight heparin (e.g., enoxaparin), and other immunosuppressants (e.g., azathioprine, mycophenolate, methotrexate).[55][63]​​​[66]​​

Consultation with a specialist is recommended before initiating systemic treatment.

Primary options

However, UVB should not be used with certain oral immunosuppressive drugs, including cyclosporine, azathioprine, and mycophenolate. UVB may be used with methotrexate in some patients.[84]

Consult a specialist for guidance when combining phototherapy with pharmacotherapy.

scalp disease

Back
1st line – 

topical or intralesional or oral corticosteroid

High-potency topical corticosteroids are used as first-line therapy.[56]​​[67][68]​ However, intralesional corticosteroid injection (e.g., triamcinolone) may be more effective.[55]​​

Systemic corticosteroids may be required for severe disease.[67][68]

Tapering down corticosteroid strength or dose when able to is important to avoid side effects.

Long-term therapy has numerous potential risks.

Consultation with a specialist is recommended before initiating systemic treatment.

Primary options

clobetasol topical: (0.05%) apply to the affected area(s) once daily, maximum 50 g/week

oral disease

Back
1st line – 

topical corticosteroid ± oral corticosteroid

Atrophic/ulcerative oral LP is best treated with topical corticosteroid preparations formulated for oral use.[72][74][85][86][87][88][89]

Severe disease unresponsive to topical measures is usually treated with a short course of systemic corticosteroids, with topical oral corticosteroids as further maintenance.[72]

Some physicians recommend dissolving oral prednisone or betamethasone tablets in water and using as a mouthwash.

Oropharyngeal candidiasis can be prevented by concomitant topical antifungal therapy.

Consultation with a specialist is recommended before initiating systemic treatment.

Primary options

triamcinolone topical: (0.1% in orabase) apply sparingly to the affected area(s) two to three times daily

OR

clobetasol topical: (0.05% in orabase) apply sparingly to the affected area(s) twice daily

Secondary options

prednisone: 30-80 mg orally once daily for 4-6 weeks, then taper gradually according to response

-- AND --

triamcinolone topical: (0.1% in orabase) apply sparingly to the affected area(s) two to three times daily

or

clobetasol topical: (0.05% in orabase) apply sparingly to the affected area(s) twice daily

Back
Consider – 

symptom relief

Treatment recommended for SOME patients in selected patient group

The treatment aims of symptomatic oral LP are to heal areas of painful ulceration and blistering.[72] It is important that the patient maintains a high standard of oral hygiene and avoids any causes of oral trauma like ill-fitting dentures.

Symptomatic nonulcerative LP is best treated with barrier agents and/or a topical anesthetic as a mouth rinse or gel.[72] Agents to consider include benzydamine mouth rinse, topical lidocaine, and aloe vera gel.[72][73]

Analgesics (e.g., acetaminophen) may provide pain relief in certain patients; however, as nonsteroidal anti-inflammatory drugs may worsen symptoms, a specialist should be consulted before deciding on appropriate analgesia.

Primary options

benzydamine topical: (0.15%) 15 mL swished in the mouth and spit out every 3 hours when required

OR

lidocaine oropharyngeal viscous solution: (2%) 15 mL every 3 hours when required (swish around in mouth and spit out), maximum 8 doses/day

OR

aloe (Aloe vera): apply to the affected area(s) twice daily

OR

acetaminophen: 325-1000 mg every 4-6 hours when required, maximum 4000 mg/day

Back
2nd line – 

immunosuppressant/immunomodulator or retinoid

Other forms of treatment used for recalcitrant oral disease include sulfasalazine, azathioprine, hydroxychloroquine, topical or oral retinoids (e.g., tretinoin, acitretin),​ topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus),​ mycophenolate, or methotrexate, although data for efficacy are very limited.[55][77][78]​​​​

Malignancy risk is elevated with long-term use of immunosuppressants and regular routine blood tests are recommended.

Concerns have been expressed regarding the potential of tacrolimus to encourage malignant transformation of the mucosa, though the evidence for this is very limited.[79]​ Combined with the risk of malignant transformation in oral LP of around 1%, it is important to monitor patients treated with topical calcineurin inhibitors, particularly those with erosive and ulcerative lesions.[79]

Consultation with a specialist is recommended before initiating systemic treatment.

Primary options

tacrolimus topical: (0.03% or 0.1%) apply to the affected area(s) twice daily for 1-2 months

OR
