Yes, or so I hear. The info sheets report a number of different denominations.

Belgrade isn't unhealthy living, although I wished one could buy organic food, especially for my son. Medical care isn't so hot. If you're not a State Department person and have to take care of these matters yourself, choose private clinics (Belmedic is a good one). Doctors are often very good, whereas equipment and technology are below standard. Private clinics have to be paid on the spot, but are affordable for non-Serbians.Treatments in hospitals should be avoided, if only for the different take on treating a patient. Sometimes, they don't allow visitors. Fathers are not allowed in the birth room. No rooming-in for babies and new mothers. Standards of hygiene are very different.Medications are available on a limited basis although there are pharmacies galore in Belgrade. Some prescriptions aren't readily available and can't be ordered as simply as in the US or in Germany. Bring all your important medications and things like cold medicine, cough syrup, etc. (Especially when you have kids since kid's meds are even harder to come by.) Pharmacies also carry diapers and wipes - the Serbian brand is horrible but Pampers are everywhere.
