Prednisone is a corticosteroid that can cause insomnia, restlessness, and difficulty falling or staying asleep. It may also cause increased energy, anxiety, mood changes, or a "wired" feeling that makes sleep harder.

Why Does Prednisone Interfere With Sleep?
Prednisone can have stimulating effects. It may increase alertness, cause restlessness or anxiety, and affect the body's normal cortisol-related rhythm. Insomnia is more likely with higher doses or longer treatment, but it can also happen during a short course.
What Can You Do if Prednisone Keeps You Awake?
If you take prednisone once daily, taking it in the morning with breakfast may reduce its effect on nighttime sleep. Do not change the timing if your clinician prescribed multiple daily doses, a specific tapering schedule, or steroid replacement therapy. Ask your clinician or pharmacist first.
You can also try:
- Avoiding caffeine later in the day
- Keeping the same bedtime and wake time each day
- Avoiding naps late in the afternoon
- Keeping your bedroom dark, quiet, and cool
- Telling your doctor or pharmacist if insomnia lasts more than a few nights or affects your daily activities
Your prescriber may change the dose, timing, or treatment plan. Do not stop prednisone suddenly, especially if you have taken a high dose or used it for more than a few weeks. Stopping abruptly can cause withdrawal problems and allow the condition being treated to flare.
When Should You Contact a Doctor Urgently?
Contact your prescriber promptly if insomnia occurs with severe anxiety, unusually elevated mood, depression, confusion, memory problems, hallucinations, or other major behavior changes. Corticosteroids can sometimes cause serious mental health effects.
Seek emergency help if you have thoughts of self-harm, lose contact with reality, develop severe confusion, have trouble breathing, or show signs of a serious allergic reaction.
If morning dosing does not improve your sleep, ask your prescriber or pharmacist what to do next. Do not change the dose or stop prednisone on your own.
