Deltasone (Prednisone) Tablets: Uses, Dosage and Safety Guide

Deltasone is a brand of prednisone, an oral corticosteroid that reduces inflammation and suppresses an overactive immune response. It is used for a wide range of corticosteroid-responsive allergic, respiratory, joint, skin, bowel and autoimmune conditions. Treatment may involve a short course for an acute flare or a carefully monitored longer course. This guide explains how the tablets work, the principles behind dosing and tapering, and the main safety considerations.

What Deltasone is and why it is prescribed

Prednisone is a synthetic corticosteroid related to cortisol, a hormone produced naturally by the adrenal glands. Deltasone is taken by mouth, and we offer tablets in four strengths: 5 mg, 10 mg, 20 mg and 40 mg. Multiple strengths allow a prescriber to select an appropriate daily amount and, when necessary, reduce it in planned stages.

Corticosteroids such as prednisone are not antibiotics or conventional painkillers. They act on inflammatory and immune processes, which is why the same medicine can be used for conditions affecting very different parts of the body. The inactive ingredients may differ between tablet products, so anyone with a known excipient allergy should check the relevant product information.

Inflammation and corticosteroid treatment

Inflammation is a normal response to infection or injury, but it can become excessive or misdirected. Depending on the affected tissue, this may cause pain, swelling, breathing difficulty, skin damage, bowel symptoms or impaired organ function. Prednisone does not correct the underlying cause of most chronic diseases, but it can reduce inflammatory activity, relieve symptoms and help protect tissues while the underlying condition is investigated or a longer-term treatment takes effect.

How prednisone works in the body

Prednisone is converted mainly in the liver to prednisolone, its active metabolite. Prednisolone binds to glucocorticoid receptors inside cells, and the resulting complex alters the expression of many genes involved in inflammation and immunity. This reduces inflammatory chemical messengers, changes white blood cell activity and limits the leakage of fluid from small blood vessels.

Because these effects occur throughout the body rather than at one highly specific target, prednisone can work across many inflammatory conditions. The same broad action also accounts for its varied adverse effects, particularly at higher doses, during repeated courses or with prolonged treatment.

Effectiveness and clinical role

Systemic corticosteroids have a well-established role in controlling acute asthma exacerbations, severe inflammatory and allergic episodes, inflammatory bowel disease, rheumatoid arthritis and other autoimmune conditions, and selected skin and blood disorders. Prednisone can act more quickly than many disease-modifying treatments, making it useful for a flare or as temporary treatment while a slower-acting medicine takes effect.

Its value depends on the diagnosis, dose and duration. Prednisone is not usually preferred as an unrestricted long-term solution because cumulative exposure increases the risks of infection, osteoporosis, diabetes, cataracts, glaucoma, adrenal suppression and other complications. For many conditions, the goal is the lowest effective dose for the shortest suitable period.

Established uses

A prescriber may recommend oral prednisone for conditions such as:

• severe allergic or hypersensitivity reactions as part of an appropriate treatment plan
• acute asthma exacerbations and other corticosteroid-responsive airway inflammation
• rheumatoid arthritis and other inflammatory joint diseases
• flares of inflammatory bowel disease, including ulcerative colitis and Crohn's disease
• selected inflammatory skin disorders
• certain autoimmune, connective tissue and blood disorders

The presence of inflammation alone does not mean prednisone is suitable. Infection, the cause and severity of the symptoms, previous corticosteroid exposure and other medical conditions all affect the decision.

Strengths and general dosing principles

We offer Deltasone oral tablets in 5 mg, 10 mg, 20 mg and 40 mg strengths. The prescribed dose can vary substantially according to the condition, its severity, age or body size, other illnesses and the response to treatment. The following patterns are general educational examples rather than regimens for an individual reader.

Prednisone is often taken with food to reduce stomach upset. Morning administration is commonly preferred for once-daily treatment because it more closely follows the body's cortisol rhythm and may reduce sleep disturbance. However, timing and dose division depend on the condition and the prescriber's directions.

Do not stop sustained, high-dose or repeated corticosteroid treatment abruptly unless a clinician directs this. After the adrenal glands have reduced their own cortisol production, sudden withdrawal can cause marked fatigue, weakness, nausea, low blood pressure and a return or worsening of the treated condition. A taper should follow an individual plan rather than a fixed schedule applied to everyone.

Elimination and half-life

After conversion from prednisone, prednisolone has an elimination half-life of roughly two to three hours in many adults. Its biological effects last much longer than its concentration in the blood, generally placing prednisone among intermediate-acting corticosteroids. This difference between elimination and duration of action helps explain why once-daily administration is possible in many treatment plans.

Liver or kidney disease, age, interacting medicines and changes in protein binding can affect handling of corticosteroids. A prescriber may therefore alter the choice of corticosteroid, dose or monitoring rather than relying on the usual half-life alone.

Contraindications and important precautions

Deltasone must not be used by someone with known hypersensitivity to prednisone or an ingredient in the relevant tablet. Systemic fungal infection is another important contraindication unless appropriate specialist management indicates otherwise. Live vaccines may also be contraindicated while a person is receiving an immunosuppressive corticosteroid dose.

Additional caution is needed with active or recent infection, tuberculosis exposure, diabetes, high blood pressure, heart failure, osteoporosis, peptic ulcer disease, glaucoma, cataracts, seizure disorders and certain psychiatric conditions. Prednisone can suppress or mask signs of infection, so serious infection may develop without the expected fever or inflammatory symptoms.

Pregnancy and breastfeeding

Prednisone crosses the placenta. During pregnancy, a prescriber must weigh the expected maternal benefit against potential fetal risk, particularly when treatment is prolonged or involves high doses. Extended systemic corticosteroid exposure has been associated with impaired fetal growth and may affect adrenal function in a newborn.

Prednisone and prednisolone pass into breast milk in small amounts. Short-term or low-dose treatment is generally considered compatible with breastfeeding, but prolonged or high-dose therapy may require monitoring of the infant for growth or adrenal effects. A clinician may sometimes recommend allowing several hours between a dose and a feed to reduce exposure.

Children and older adults

Prednisone can be used in children when clinically indicated, but paediatric dosing requires careful calculation and monitoring. Prolonged systemic treatment can suppress growth and affect bone development. Older adults may be more susceptible to osteoporosis, blood glucose changes, fluid retention, high blood pressure, cataracts, glaucoma and skin fragility.

Driving and operating machinery

Prednisone is not usually sedating, but dizziness, blurred vision, insomnia, agitation, euphoria or other mood changes can impair driving in some people. Anyone experiencing these effects should avoid driving or operating machinery until they have resolved and the medicine's effects are understood.

Monitoring during treatment

Monitoring depends on the dose and duration but may include blood pressure, blood glucose, weight, electrolytes, eye health and signs of infection. Bone protection may be considered during prolonged treatment, especially for people with other osteoporosis risk factors. Children receiving extended treatment also need growth monitoring.

Prescription status and our ordering policy

In Australia, prednisone tablets are Schedule 4 Prescription Only Medicines and require a prescription from an authorised prescriber for lawful supply. This is the medicine's Australian regulatory classification.

Separately, our ordering policy for Deltasone does not require customers to upload a prescription document through our checkout. This ordering step does not change the medicine's Australian classification or replace appropriate assessment by a qualified clinician. Our pharmacist team is available by email and online chat 24 hours a day, 7 days a week, for medicine-related questions.

Interactions with medicines, vaccines and alcohol

Prednisone can interact with prescription medicines, non-prescription products and vaccines. A doctor or pharmacist should review current treatment before a course begins, especially when corticosteroid therapy will be prolonged. Important examples include:

• non-steroidal anti-inflammatory drugs such as ibuprofen and aspirin, which can increase the risk of stomach irritation, ulceration or bleeding
• insulin and other diabetes medicines, because prednisone can raise blood glucose and alter treatment requirements
• potassium-depleting diuretics, which may add to the risk of low potassium
• warfarin and other anticoagulants, whose effects may change and require closer monitoring
• live vaccines, which are generally avoided during immunosuppressive corticosteroid treatment
• rifampicin and certain anticonvulsants, which may reduce corticosteroid exposure by increasing metabolism
• some antifungal, antiviral and other medicines that inhibit corticosteroid metabolism and may increase adverse effects
• alcohol, which may add to stomach irritation, particularly when other gastrointestinal risk factors are present

Prednisone also suppresses immune responses and can reduce the response to some vaccines. Vaccination timing should therefore be discussed with a clinician rather than changed without advice.

Side effects and when to seek help

Short courses are often tolerated without serious problems, although adverse effects can still occur. Common effects include increased appetite, indigestion, fluid retention, difficulty sleeping, restlessness, mood changes and temporary rises in blood glucose. Higher doses and longer courses increase the likelihood of weight gain, rounded facial appearance, easy bruising, thin skin, muscle weakness, osteoporosis, cataracts, glaucoma, high blood pressure, diabetes and infection.

Seek prompt medical attention for signs of infection, new or severe vision problems, black or tarry stools, vomiting blood, marked swelling, significant shortness of breath, severe muscle weakness or major changes in mood, thinking or behaviour. Emergency care is required for difficulty breathing, facial or throat swelling, collapse, or another sign of a severe allergic reaction.

Symptoms of adrenal insufficiency can emerge during a rapid dose reduction, after treatment ends or during major illness or surgery following prolonged therapy. Severe weakness, persistent vomiting, dizziness, fainting or confusion requires urgent assessment. People who have used systemic corticosteroids for an extended period should tell healthcare professionals about that treatment when receiving emergency care.

Suspected overdose

If more prednisone than intended has been taken, contact the Australian Poisons Information Centre on 13 11 26 for advice, even if no immediate symptoms are apparent. Call emergency services for collapse, severe confusion, breathing difficulty, a seizure or another life-threatening symptom.

Excessive acute or repeated dosing may intensify fluid retention, high blood pressure, mood disturbance, electrolyte changes and elevated blood glucose. There is no specific antidote; management is based on the amount taken, the timing, other medicines involved and the symptoms present. Keep the medicine container or packaging available when seeking advice.

Storage

Store Deltasone tablets at 20°C to 25°C; excursions between 15°C and 30°C are permitted. Keep the container tightly closed, protect the tablets from moisture and keep them out of reach of children. Do not use tablets after their expiry date. Take unwanted or expired medicines to a pharmacy disposal service rather than placing them in household rubbish or pouring them down a drain.

Benefits and trade-offs

Prednisone's main advantage is its broad and often relatively rapid anti-inflammatory action. It can control a significant flare while a slower treatment begins working, and oral tablets make systemic treatment possible without an injection. The available strengths also support dose adjustment when a carefully staged taper is required.

The trade-off is that systemic exposure affects more than the inflamed tissue. Risks rise with dose, duration and repeated treatment, and some complications require active monitoring. Prednisone is therefore most useful when there is a clear corticosteroid-responsive condition and a plan for reviewing response, reducing exposure when possible and managing relevant risk factors.

Generic prednisone and therapeutic alternatives

A generic prednisone tablet contains the same active ingredient at the stated strength, but products may differ in appearance, inactive ingredients and local registration or availability. A pharmacist or prescriber can confirm whether a particular product is an appropriate substitute; equivalence should not be assumed solely because two products contain prednisone.

Prednisolone is a different medicine, although it is the active metabolite formed from prednisone and may be preferred when conversion in the liver is a concern. Dexamethasone and other systemic corticosteroids have different potencies and durations of action, so their milligram strengths are not directly interchangeable with prednisone.

For inflammation confined to a particular area, an inhaled, topical, locally injected or other targeted corticosteroid may reduce whole-body exposure compared with an oral tablet. These dosage forms are therapeutic alternatives for selected conditions, not generic equivalents of Deltasone. The appropriate option depends on the diagnosis, site and severity of inflammation, required speed of action and individual safety considerations.
