Medical Editor: John P. Cunha, DO, FACOEP
Targretin (bexarotene) 1% Gel is a retinoid used to treat skin lesions of cutaneous T-cell lymphoma (CTCL) (Stage 1A and 1B) in patients who have not responded to or not tolerated other therapies. Common side effects include redness, itching, warmth, swelling, burning, scaling, or other irritation.
Targretin gel should be initially applied at a dosing frequency once every other day for the first week. The application frequency should be increased at weekly intervals to once daily, then twice daily, then three times daily and finally four times daily according to individual lesion tolerance. Targretin may interact with vitamin A supplements, insect repellents or other products that contain DEET, and other topical products used on the affected area at the same time. Tell your doctor all medications and supplements you use. Targretin gel must not be given to a pregnant woman or a woman who intends to become pregnant. It can harm a fetus. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Targretin Gel FDA Prescribing Information: Side Effects
The safety of Targretin® gel has been assessed in clinical studies of 117 patients with CTCL who received Targretin® gel for up to 172 weeks. In the multicenter open-label study, 50 patients with CTCL received Targretin® gel for up to 98 weeks. The mean duration of therapy for these 50 patients was 199 days. The most common adverse events reported with an incidence at the application site of at least 10% in patients with CTCL were rash, pruritus, skin disorder, and pain.
Adverse events leading to dose reduction or study drug discontinuation in at least two patients were rash, contact dermatitis, and pruritus.
Of the 49 patients (98%) who experienced any adverse event, most experienced events categorized as mild (9 patients, 18%) or moderate (27 patients, 54%). There were 12 patients (24%) who experienced at least one moderately severe adverse event. The most common moderately severe events were rash (7 patients, 14%) and pruritus (3 patients, 6%). Only one patient (2%) experienced a severe adverse event (rash).
In the patients with CTCL receiving Targretin® gel, adverse events reported regardless of relationship to study drug at an incidence of 5% are presented in Table 1.
A similar safety profile for Targretin® gel was demonstrated in the Phase I-II program. For the 67 patients enrolled in the Phase I-II program, the mean duration of treatment was 436 days (range 12-1203 days). As in the multicenter study, the most common adverse events regardless of relationship to study drug in the Phase I-II program were rash (78%), pain (40%), and pruritus (40%).
