It is best to bring your prescription drugs with you. Prescriptions from doctors abroad are generally not honored at pharmacies which may require that you see a local doctor. Also, the specific drug that you take at home may not be available on-island.
US health insurance is not accepted on Aruba. Be prepared to pay with cash or credit card at a doctor’s office, pharmacy or hospital. 
Rental of wheelchairs, walkers, crutches, special medical equipment and home health care products are available through Labco (tel 582-6651).
