Final answer:
Taking prednisone 5 mg by mouth can lead to symptoms including increased appetite, weight gain, insomnia, and mood swings due to its glucocorticoid properties.
Step-by-step explanation:
One of the symptoms of taking prednisone at a dose of 5 mg by mouth (PO) is increased appetite. Prednisone is a synthetic derivative of cortisol, and like natural glucocorticoids, it can have an array of side effects. Some common side effects include weight gain, insomnia, and mood swings. It is known to reduce inflammation and is used to treat conditions like asthma and arthritis. However, its use, particularly over the long term, can lead to various health problems including the aforementioned side effects.
