<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have shingles and no health insurance. I still have some amoxicillan sitting in my fridge that hasnt expired. Will it help with the shingles? Ive had shingles before so Im sure the signs I have mean I have it. I have a constant headache, fatigue and a small rash that is identical to the rash I had when I had shingles last time.  <response>: Hi, Amoxicillin wouldnt work here, as it is antibacterial not antiviral Chat Doctor. So, you have to go for acyclovir800 mg 5 times a day for 5 days or of acyclovir 3 times a day, start only within 3 days of symptoms, after 3 days no active treatment require. If pain still there need appropriate painkiller. Have plenty of fruit juices, water and it c. I had many patients with similar illness, and they respond very well with diet and painkillers. Fatigue will subside soon in 2-3 days on its own. Review after 5 days and in between if things wouldnt control or minimize.
