Many physicians suggest any of the following lubricating creams or ointments. They can all be purchased without a prescription: Bacitracin, A and D Ointment, Eucerin, Polysporin, and Vaseline. Up to three applications a day may be needed, but usually every night at bedtime is enough. A saline nasal spray will also moisten dry nasal membranes. If the nosebleeds persist, you should see your doctor. Using an endoscope, a tube with a light for seeing inside the nose, your physician may find a problem within the nose that can be fixed. He or she may recommend cauterization (sealing) of the blood vessel that is causing the trouble.
