Question: Antibiotics for mono?

 storaged - Thu Dec 06, 2007 3:09 pm

Hi, I am an 18-year-old female. About a month ago I had a severe sore throat, cough, fever, etc. My doctor just looked in my throat and said it was pharyngitis, and prescribed me a Z-pack. The Z-pack did nothing, so we called her back and she prescribed Amoxicillin. After finishing the Amoxicillin I felt better for a few days, but now I feel weak, my throat has white in it, my lymph nodes are swollen, my temperature is 101, and I have body aches. I looked up the symptoms and thought I probably had mono, so I went back to the doctor today. She felt my lymph nodes, took my temperature, and took a throat culture, and told me I was right. But then she prescribed me more Amoxicillin.

My question is, will Amoxicillin help in any way? I know mono is a virus and I'm very against taking unnecessary antibiotics. Is there any possible way more antibiotics could help with mono?

User avatar Hi Storaged,

If your infection is mono antibiotics will not help. In fact, taking the amoxicillin may cause a rash. Mono is caused by ebstein-barr virus (EBV). There is an interaction between EBV and amoxicillin that causes a rash to develop all over the body.

EBV can be tested for with a blood test called a monospot.

If the sore throat is caused by the group A strep bacteria, the amoxicillin is appropriate. Strep can also be tested for.

I would suggest you talk with your doctor about having these tested for.

Best wishes.
