RAYOS is available by prescription only. Your pharmacy should carry RAYOS. In the event they do not have it on the shelf, ask your pharmacist to order it for you. RAYOS can be delivered to your pharmacy, typically within 24 hours. Ask your doctor if RAYOS may be right for you.

RAYOS is the first and only delayed-release form of prednisone. There are generic forms of prednisone, but there is no generic substitute for delayed-release prednisone. RAYOS is different in that only RAYOS releases the anti-inflammatory action of prednisone about 4 hours after taking the tablets.

Prednisone is a type of corticosteroid. Corticosteroids are different from anabolic steroids, which are sometimes used by body builders. Corticosteroids closely resemble hormones that your body produces naturally and are used to help reduce inflammation, which can in turn relieve pain.

A delayed-release medication postpones the drug effect for an amount of time after you take the dose. With RAYOS, the prednisone dose is released in about 4 hours.

Your doctor will tell you when to take RAYOS. For example, your doctor may ask you to take RAYOS at bedtime. In clinical studies, RAYOS was taken around 10 pm.

RAYOS should be taken once a day. RAYOS tablets should not be broken, divided, or chewed because the delayed release of prednisone depends on a whole tablet. RAYOS is available in 1-mg, 2-mg, and 5-mg tablets. Your doctor will decide what dose is right for you based on your symptoms and will talk to you about when to take it. Your doctor may tell you to take more than 1 pill or a combination of 2 different dose sizes. Always follow the dosing instructions from your doctor.

RAYOS should be taken with food. In a clinical study, RAYOS was taken with a light meal or snack if more than 2.5 hours had passed since the evening meal. RAYOS worked similarly when taken with dinner or with a light meal.

If you miss a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and take RAYOS at the next regularly scheduled time. Do not take an extra dose to make up for the missed dose.

Talk with your doctor before you stop taking RAYOS. You may need to gradually reduce the amount of RAYOS you are taking. Stopping RAYOS suddenly may cause unwanted side effects.
