Tanning and antibiotics?

I had bronchitis and was put on an antibiotic called azithromycin.It said to stay out of the sun and not to use tanning beds while on it.I think its also known as z pack.I took 2 pills the 1st day and took one pill the next 2 days but on the 3rd day I had an allergic reaction so the last time I took it was on Saturday night.I am now on amoxicillin I started it yesterday and the pharmacist said its ok to go tanning while on it.Anyways I havent taken the z pack since saturday and was wondering if it would be safe if I started going back to the tanning beds again.Thanks
