Precautions
It is very important that your doctor check your progress three months after the treatment. This will allow your doctor to see if the medicine is working properly and to check for unwanted effects.
This medicine causes the treated areas of your skin to be more sensitive to light. Avoid exposure to sunlight or bright indoor light for 3 hours after the medicine is applied to your skin. This includes medical examination lights, operating room lights, tanning beds, or any lights that are close to you. You should also avoid exposure to sunlight or bright indoor light on the treated skin for 2 days after the light treatment (photodynamic therapy). Cover the treated areas of your skin. If you must go out during daylight hours, wear a protective hat or clothing. Check with your doctor if you have questions about this.
Avoid cold temperatures for 3 hours after the medicine is applied to your skin. Wear warm clothing and cover the treated area if you are in cold places.
