Hello have tonsillitis and have been put on penicillin two tablets four times daily without food, my urine is a florecent. yellow is this normal?

Don't worry: You might even smell the antibiotic in your urine. The color is usually related to your level of hydration. The clearer the better. If you are fighting an infection it is best to drink lots and lots of fluids. You will be helping your body fight the infection and you will feel better. Most people are somewhat dehydrated normally. When sick, they tend to drink less, and this makes things worse.
