My in-laws are visiting us for a few weeks. One of them ran out of blood-pressure pills. Local pharmacies have them but they only sell them by prescription. Being just tourists, my in-laws do not have a medical insurance. A visit to a doctor to get a prescription could be rather expensive (but I'll go for it if there is no other choice). The drug itself is cheap, about $50 as quoted by a local CVS.

Is there a way to get this drug without having to take him to a doctor? To make things worse, my in-laws do not speak English. Maybe there is a simple way to get a prescription if I know what he needs?

Any hints? Thanks!
