Yes, there are many pharmacies (Farmacia) in Jaco, and most have a doctor available. Many things are over the counter, but if you need specific prescriptions filled, you should take care of that before you leave, as there are no guarantees that the pharmacy will have what you need. Also, remember that grocery stores do not carry medications such as Tylenol or Advil, so you will need to buy those things in the pharmacies, which usually close around 8 pm in Jaco.
