Hi!
Flu-like symptoms ,together with headache and muscle pain, are rare side effects while using Aldara. More common are mild local skin reactions such as itching, peeling, burning, rush, pain, erosion and edema at the site of application or surrounding areas. If you experience a severe skin reaction like erosion, you should wash it off and notified your doctor.
I'll suggest you to inform your doctor and ask to decrease the application, because some trials showed that the side effects were more common and more intense with daily use rather than 3 times a week.
All best to you!
