Will Pharmacias in Progresso Nuevo Give Pencillin Shots?

In my old age, I seem to catch every cold going around and with side effects, they last a month. Had so many I know the drill; penicillin shot after about 5 days onset, then Amoxycillin for 10 days. I prefer the shot plus azithromax, but docs in the USA seem to prefer Amoxycillin and frequently want to skip the shot. Just wondering if I can custom design my treatment in Progresso.
