FAQ
Tell a pharmacist or prescriber if swallowing tablets is difficult so they can advise on an appropriate option. Do not crush, chew, or alter a prednisone tablet unless the package instructions or a pharmacist specifically says it is suitable.
Not necessarily. Tablet color, shape, size, markings, packaging, and inactive ingredients can differ between manufacturers, even when the active ingredient is prednisone and the strength is the same.
A different appearance alone does not show that the product is incorrect. Compare the package label for the active ingredient, strength, dosage form, manufacturer, lot number, expiration date, and tablet imprint when present. Do not use the tablets until any mismatch in ingredient, strength, dosage form, imprint, seal, or condition has been checked.
Store the tablets at 68°F to 77°F; excursions between 59°F and 86°F are permitted. Keep the container tightly closed and protect it from moisture.
Prednisone is a corticosteroid used to reduce inflammation and suppress immune activity when needed. It is used for many corticosteroid-responsive conditions, including severe allergic, skin, respiratory, rheumatologic, gastrointestinal, kidney, blood, eye, neurologic, endocrine, and certain cancer-related conditions, as well as organ-transplant treatment.
Prednisone tablets are taken by mouth, usually with food to help reduce stomach irritation. The dose, timing, and treatment length depend on the condition being treated and must follow the prescribed directions; prednisone should not be stopped abruptly after longer-term use unless a prescriber directs a taper.
Description
Deltasone is the brand name for prednisone, an oral corticosteroid tablet that we carry in 5 mg, 10 mg, 20 mg, and 40 mg strengths. This guide walks through what the tablets are for, what to check before starting them, how to store them at home, and what to expect when you order from us.
Quick overview
Prednisone belongs to the corticosteroid drug class. It works by damping down the immune system and reducing the release of inflammatory chemicals in the body, which is why prescribers use it across a wide range of conditions where inflammation or an overactive immune response is the underlying problem. That includes certain types of arthritis, asthma flares, allergic reactions, some skin conditions, and inflammatory bowel disease, among others. Because the same tablet can be used for very different conditions, dosing is highly individualized: a short course for a flare-up looks nothing like a longer, tapered regimen for a chronic condition, and the prescribing clinician sets the strength, schedule, and duration based on the specific diagnosis. If joint inflammation is what brought you here, our Arthritis category page rounds up other treatment options worth comparing.
Who prednisone tablets are typically for
Prednisone is well established for use in adults and has recognized pediatric uses as well, though children on corticosteroids need closer monitoring for effects like slowed growth. A few situations call for extra caution rather than automatic exclusion. People with diabetes or impaired glucose tolerance should expect blood sugar to run higher on prednisone and may need to check glucose more often or adjust their diabetes medication. Pregnant patients and prescribers need to weigh the potential benefit against possible fetal risks, including cleft palate or fetal adrenal suppression, before starting treatment. Breastfeeding parents should use prednisone cautiously, since it passes into breast milk and higher doses could affect a nursing infant. Prednisone is not appropriate for anyone with a known hypersensitivity to prednisone or another tablet ingredient, or for anyone with a systemic fungal infection, and it should not be started without medical input if any of these situations apply to you.
Before you start using it
A little preparation before the first dose helps avoid surprises later.
Checks worth making first
Confirm there's no known allergy to prednisone or to any tablet ingredient.
Flag diabetes, prediabetes, or any history of glucose intolerance so blood sugar can be tracked from day one.
Mention pregnancy or breastfeeding so the prescriber can weigh benefits against risks.
List other medications and supplements, since prednisone interacts with drugs such as NSAIDs, certain diuretics, some vaccines, and medications metabolized through the same liver pathways.
Prednisone tablets are usually taken with food or milk to reduce stomach upset, and once-daily doses are often taken in the morning to mirror the body's natural cortisol rhythm. The anti-inflammatory effect may become noticeable within hours to a day or two during an acute flare, while the response to longer treatment varies by condition. If prednisone has been taken at a high dose or for a prolonged period, do not stop it abruptly unless the prescriber advises you to do so; a gradual taper may be needed to help the body's own cortisol production recover safely. Common side effects include increased appetite, mood changes, trouble sleeping, and fluid retention, while higher doses in the 20-40 mg range can bring on dizziness, blurred vision, or confusion, so it's worth being cautious about driving or operating machinery until you know how a dose affects you.
Handling and storage at home
Keeping tablets stable is mostly about controlling temperature and moisture. Store Deltasone tablets at 68°F to 77°F, with brief excursions down to 59°F or up to 86°F considered acceptable during transport or minor fluctuations. Keep the tablets in their original, tightly closed container rather than a pill organizer exposed to bathroom humidity, and keep the container out of direct sunlight. As with any prescription medication, storage should be somewhere out of the reach and sight of children.
Ordering and delivery with us
We currently list Deltasone in 5 mg, 10 mg, 20 mg, and 40 mg tablets. The 5 mg strength comes in packs of 180, 270, or 360 tablets, while the 10 mg, 20 mg, and 40 mg strengths are available in 60, 90, 120, 180, 270, or 360-tablet packs, so you can match the pack size to the length of a prescribed course or to an ongoing refill schedule. Prednisone tablets are a prescription-only medication in the United States. If you're unsure what information is needed for your order, our support team can confirm the details before anything ships.
Once an order is placed, we pack it discreetly and send it directly to the shipping address you provide, with no medication labeling visible on the outer packaging and your order details kept confidential throughout. Our team has supported US customers since 2008, and licensed pharmacist support is available 24/7 by email, online chat, or phone if you have questions about your order, a dose, or anything else before or after your delivery arrives.

Q
Asked by Ashley S, Philadelphia, United States
Before I order from Philadelphia, can I check whether prednisone can be shipped to my ZIP code?
A
Answered by Support team
Yes. Enter your full Philadelphia delivery address and ZIP code at checkout, and we will show the shipping options available for that destination before you place the order.
Q
Asked by Stephanie J, San Francisco, United States
I have type 2 diabetes and was prescribed prednisone for inflammation. Can it affect my blood sugar?
Yes. Prednisone can raise blood glucose, worsen diabetes control, and increase the amount of insulin or other diabetes medicine a person needs. Blood glucose monitoring and possible adjustment of diabetes treatment should be arranged with the clinician managing your diabetes.
