The U.S. Food and Drug Administration (FDA) is warning about reports of severe allergic reactions and herpes zoster (shingles) associated with the use of Picato gel (ingenol mebutate). Picato is used to treat actinic keratosis, a scaly, crusty lesion on the skin that may be red or yellow in color.
We have also received reports of cases involving severe eye injuries and skin reactions associated with the application of Picato gel. Some cases were associated with Picato gel not being used according to the instructions for use on the label. As a result, we are requiring changes to the label to warn about these new safety risks and to provide additional instructions on the safe and appropriate application of the product.
Patients should use Picato gel as prescribed by their health care professionals, and should not use it on an area of skin larger or for a longer period than instructed in the drug label. Also patients should avoid applying the gel in, near, and around the mouth, lips and eye area. Accidental transfer of Picato gel from the hands even after washing has occurred, including through application of make-up and insertion of contact lenses. Applying Picato gel in a manner other than recommended in the product label has been associated with severe skin reactions and eye injuries (See Additional Information for Patients section).
Patients who experience a severe allergic reaction should stop using Picato gel and seek immediate medical attention. The allergic reaction may include throat tightness, difficulty breathing, feeling faint, or swelling of the lips or tongue. Patients should also stop using the product and contact their health care professionals if they develop hives, itching, or severe skin rash. If accidental eye exposure occurs, flush the eyes thoroughly with water and seek medical care.
Actinic keratosis, which is treated with Picato gel, is a scaly, crusty lesion on the skin that may be red or yellow in color. The lesions are typically located on areas exposed to the sun such as the face, scalp, back of the hands, and chest. The majority of these lesions are not harmful. However, actinic keratosis may occasionally develop into skin cancer.
We reviewed postmarketing cases submitted to the FDA Adverse Event Reporting System (FAERS) for Picato gel. In some cases, severe eye injuries and skin reactions occurred when the application of the product was not according to the instructions found in the labeling. Other cases described severe allergic reactions, including anaphylaxis. Herpes zoster was also reported.
We urge patients and health care professionals to report side effects or medication errors involving Picato gel to the FDA MedWatch program, using the information in the “Contact FDA” box at the bottom of the page.

Since the approval of Picato gel in January 2012, FDA has received adverse event reports describing application of Picato gel in a manner that is not according to the recommendations in the label, which in some cases resulted in severe eye injuries and skin reactions. Severe allergic reactions (including anaphylaxis) and herpes zoster reactivation were also reported. Key findings from these cases are summarized below:
Application of the product in a manner that is not according to the instructions in the label includes:
- Wrong application site size and location. These cases included applying the product to an area larger than 25 cm2 (5 cm x 5 cm), and/or to more than a single affected area at a time.
- Wrong strength. These cases included applying the wrong product strength for the treatment area (e.g., applying the 0.05% strength to the face or scalp instead of the recommended 0.015% strength). Some resulted from prescribing errors and some from dispensing errors.
- Wrong treatment duration. These cases included application of all the unit dose tubes supplied in a carton at one time, application for less than or more than the recommended 2 or 3 consecutive treatment days.
- Wrong technique. These cases included the following:
- Washing off the product before waiting 6 hours
- Mixing Picato gel with other topical medications or lotions
- Occlusion of the treatment area with a bandage, dressing, or overlay treatment after light therapy or cryotherapy (liquid nitrogen treatment)
- Applying make-up soon after Picato gel treatment
- Applying the product less than 2 hours before going to bed
- Wrong storage conditions. All of the cases described the product as having not been kept refrigerated.
- Accidental exposure. The majority of these cases described accidental exposure to the eyes. Other areas affected were the lip, tongue or mouth, face, nose, leg, and rectum. Causes for these accidental exposures included transfer of product from the hands even after washing it off, dripping into the eyes while showering, or applying near the eyes.
Severe eye injuries:
- Some cases reported eye exposure resulting from application near or around the eyes, or transfer to the eyes via sweating, washing, showering, or insertion of contact lenses.
- Some of the injuries such as eyelid swelling, eye irritation, and pain are included in the Picato gel label.
- Other types of eye injuries include chemical conjunctivitis and corneal burns.
Severe allergic reactions and allergic contact dermatitis:
- Severe allergic reactions, including anaphylaxis, generalized rashes, and allergic contact dermatitis have been reported with Picato gel use.
Herpes zoster reactivation:
- Herpes zoster reactivation has been reported with Picato gel use. One immunosuppressed patient experienced ophthalmic herpes zoster. Most cases reported reactivation at or near the Picato gel application site. Some reported use of the product in a manner that was inconsistent with the label such as application to areas greater than 25 cm2 and use of the 0.05% concentration of Picato gel on the scalp.
