Tazarotene
Encyclopedia
Tazarotene is a prescription
topical retinoid
sold as a cream or gel. This medication is approved for treatment of psoriasis
, acne
, and sun damaged skin (photodamage). It is commonly sold in two concentrations: 0.05% and 0.1%.
Common side effect
s include worsening of acne, dry skin, itchiness, redness and in some cases extreme drying and cracking of skin. For most patients these side effects are uncomfortable but mild and decrease markedly after the first 2–4 weeks of use.
For best results dermatologists recommend applying the cream or gel once daily before bedtime after washing the face with a mild cleanser. Dermatologists recommend using a moisturizer with tazarotene so skin will not be as dry and flaky.
"There is limited evidence that tazarotene and isotretinoin
benefit patients with moderate photodamage on the face: both are associated with skin irritation and erythema
."
In addition to tretinoin, which has been associated with greater skin improvements with high concentrations, tazarotene and isotretinoin creams are also found to be effective for photodamage, but at the expense of skin irritation. More evidence is needed before any recommendations can be made on oral or topical polysaccharides or hydroxy acids. Evidence from one trial suggests that the effectiveness of 0.05% tretinoin
, is equivalent to the effects of 0.05% and 0.1% tazarotene.. However for acne vulgaris, several recent double blind studies have shown consistently superior efficacy for tazarotene and roughly equal tolerability for both treatments.
"Specifically, tazarotene reduced the number of noninflammatory and inflammatory lesions at 4, 8, and 12 weeks -- all timepoints examined during treatment. Although the reduction of inflammatory lesions compared with tretinoin did not achieve statistical significance, the reduction of open comedones at 12 weeks was 65% for tazarotene vs 44% for tretinoin (P = .034). Tazarotene also proved superior in the reduction of noninflammatory lesions at 12 weeks (55% vs 42% for tretinoin, P = .042)."
