My mother is 86 years old and has been using Aldara (immiquimod) for 5 weeks (one being a partial week). She took a break for a week so she actually started six weeks ago. She has one week left - this week! She is extremely tired and has had an increase in body pain, and she is also having more problems breathing - it is like she has the flu. The TX has been very hard on her but she has soldiered on because radiation would be even harder on her, especially given her age. How long does it take for the flu like symptoms to go away, especially the fatigue?
