Those with allergies may find Bucharest annoying in that it is both hot and very dusty in the summer, with temperatures easily exceeding 30 C in July and August, so bring whatever you might need to stay comfortable. Please note that during the summer, sun strokes and heat strokes can be very dangerous.
Pharmacies are usually open between 9 AM and 6 PM, but some will stay open through the night. In Romania, there are relatively few over-the-counter drugs available, but pharmacists are allowed to dispense limited quantities of some prescription drugs (such as pain relief medicine) for what they see as immediate needs. Bucharest has 6 designated emergency hospitals and a modern ambulance service, plus a large number of additional public and private hospitals, clinics, and dental practices.
