Prednisone is a prescription drug that can be used to treat the symptoms of low corticosteroid levels, as well as symptoms of some kinds of cancer and other conditions that may affect your skin, kidneys, blood, eyes, thyroid, stomach and lungs. Do not take this medicine for longer than recommended. At the same time, make sure you take as much as recommended, without stopping suddenly based on your own perceptions. If you have any symptoms that you find impossible to handle talk to your health care provider, and a dose adjustment may do the trick. If you have been prescribed the concentrated solution you need to have a special dropper to measure the exact amount of drug that needs to be taken. If such a dropper does not come with the medicine when you buy it, you can ask your pharmacist for one.
