This can happen during illnesses. See your doctor straight away if you become ill. If you are vomiting or unable to swallow tablets, contact your doctor urgently. You must not be without steroid medicine, particularly if you are unwell. For the same reason, it can be quite dangerous to stop long-term treatment suddenly — the body can find itself seriously short of steroid. Anyone taking regular steroid tablets should wear a Medic-Alert bracelet.
Then, if an accident occurs, and extra steroid is needed, the doctors will know. When long-term treatment is to be stopped, this must be done very gradually. The dose must be slowly reduced, often over several months. This allows the body time to start making its own cortisone again, Slow reduction will also stop unpleasant side effects, such as severe muscle aches, arthritis and depression.
Prednisone is used in severe episodes of asthma. It works slowly over several hours to reverse the swelling of the airways. If you stop too early your asthma may get worse again. The main ones are: Increased appetite and weight gain. Thinning of the bones, which can lead to bone fractures if very severe. Slowing of growth in children.
Easy bruising of the skin and slow healing of cuts. Puffiness or roundness of the face. Indigestion or stomach ulcers. Fluid retention with swelling of the ankles. Cataracts in the eyes. You can help keep the dose down by: taking your other asthma medicines as usual; using your inhaler right — ask your nurse or doctor to check your technique, use a spacer with an MDI Metered Dose Inhaler or see if an alternative device could be of help; measuring your peak flow every day, and follow a Self Management Plan , starting extra treatment early; letting the doctor know if your peak flow reading drops or you feel unwell.
Fewer side effects occur if: the steroid tablets can be taken every other day, instead of each day even if a slightly bigger dose is needed to keep the asthma under control ; the daily dose is taken as a single dose in the morning. Morning is the time the body normally products its cortisone for the day; taken during or after meals.
Bone strength Long-term steroid tablet treatment can weaken bones. Despite the small sample size in a study by Chetta et al. High dose treatment resulted in a significant decrease in basement membrane thickness, number of vessels, vascular area and mean vessel size whereas no change was observed with low dose.
Like the current study findings, there were no significant differences in the improvements in AHR and asthma symptom scores between the groups. The lack of difference between high and low dose ICS effect on inflammatory markers in the present study, compared with the findings of Chetta et al. This is supported by the correlation observed between baseline severity and magnitude of improvement in outcomes.
Modulation of alveolar macrophage inflammatory responses is an important mechanism underlying ICS efficacy in asthma [ 34 - 36 , 62 - 65 ]. There are no published randomized studies examining the dose-response relationship of the effect of ICSs on pro- and anti-inflammatory cytokine production in asthma. A smaller effect size would be expected between two active treatment arms of different doses than between active treatment and placebo but, while this difference may be considered clinically significant, a greater number of participants in each group would have been required to show statistical significance.
Previous in vitro studies have shown that inhibition of pro-inflammatory cytokines by corticosteroids is dose-dependent [ 32 , 33 ] and it was postulated that the in vivo effects of treatment on the same inflammatory markers would also be dose-dependent. The present study, however, found no significant difference between low and high dose inhaled FP groups in the change in quantity of constitutive and LPS induced cytokine mRNA and protein from alveolar macrophages. Previous studies examining the effects of ICSs on IL-1ra show conflicting results ranging from no effect [ 54 , 74 ] to elevation of IL-1ra levels post treatment [ 52 , 74 ].
In the current study, the finding of a reduction in IL-1ra mRNA and protein after treatment with FP was unexpected considering this cytokine has anti-inflammatory properties. The present study found no significant changes in the anti-inflammatory cytokine IL gene expression or protein secretion resulting from treatment with FP.
The levels of IL were close to the lower limit of detection in many subjects making resolution of changes impossible. Previous studies have revealed mixed effects of corticosteroids on IL, including no effect of in vitro dexamethasone [ 75 ], elevation after high dose inhaled budesonide [ 48 ] or inhaled triamcinolone [ 49 ] and inhibition in nonasthmatics [ 50 ]. Basement membrane thickness in asthma is reduced by corticosteroid treatment in some studies [ 73 , 76 - 80 ].
Although dose related differences in the effects of corticosteroids on bronchial mucosal BMT are apparent in some studies [ 55 , 56 ], the current study did not demonstrate a significant reduction in BMT after FP treatment for 7 weeks. This is consistent with the findings of Boulet et al. Although two previous studies have shown a significant effect of short term treatment six weeks with medium or high dose inhaled corticosteroid on BMT [ 56 , 76 ], longer treatment duration three to twelve months is more likely to alter BMT [ 73 , 77 , 78 , 82 - 84 ].
An important feature of current asthma management guidelines is the use of a maintenance dose of ICS which is the minimum effective dose to achieve asthma symptom control to limit the potential for adverse effects. Current therapy guidelines also advocate alternative approaches to achieve asthma control without increasing the ICS dose.
Combining the different anti-asthmatic mechanisms of other therapies with the attenuation of cytokine driven inflammation by ICS might be a superior and safer approach to achieving asthma control. It is possible that differences in inflammation may occur with longer term treatment and it would be important to conduct longitudinal studies with larger sample size to re-evaluate the dose-response relationship of a wide repertoire of inflammatory mediators, along with the probably smaller influence of dose on remodeling and fibrotic markers.
Additionally, prevention of asthma exacerbations and decline in lung function would be important endpoints to assess in a long term study.

Abstract Background While most of the clinical benefits of inhaled corticosteroid ICS therapy may occur at low doses, results of dose-ranging studies are inconsistent. Keywords: asthma, corticosteroids, airway hyperresponsiveness, alveolar macrophage, airway inflammation, airway remodeling.
Background Corticosteroids are the most effective medication for the prevention and treatment of asthmatic inflammation. Methods Subjects Adult volunteers were recruited, aged years, with intermittent or mild persistent or moderate persistent atopic asthma according to Global Initiative for Asthma, Global Strategy for Asthma Management and Prevention, NIH Publication, Updated Lung function and airway hyperresponsiveness AHR AHR was measured by bronchial provocation with dry powder mannitol [ 57 ].
Results Twenty three subjects completed the protocol in full. Table 1 Clinical baseline characteristics of the asthmatic subjects grouped into low and high dose FP treatment arms. Open in a separate window. Table 2 Change in each endpoint after FP in low and high dose treatment arms.
Effects of FP on clinical, physiological and in vitro parameters Because no significant differences were found between the low and high dose treatment groups, the effect of FP on the 22 asthmatics as a single group was evaluated.

On the other hand, modern steroid medications inhaled on the bronchial tubes from pressurized canisters act directly on these tubes; almost no medication is carried into the bloodstream. Although not as powerful in their immediate effects, steroids by inhalation are better suited for long-term use in the treatment of inflamed bronchial tubes because they are free of major undesirable side effects.
More information about the inhaled steroids is available in a separate pamphlet prepared by the Partners Asthma Center, entitled, Asthma and Inhaled Steroids. The remainder of this pamphlet focuses on the use of steroids in tablet or liquid form. Steroids taken in tablet or liquid form "oral steroids" are usually prescribed for asthma that has become difficult to control by any other means; they are the most effective treatment available for a severe "attack" of asthma.
Most often, they are prescribed for a short period of time: a short course may be as brief as days or as long as weeks. They are stopped when the asthma has gotten better and other treatments suffice to keep it under control. Longer periods of treatment and continuous treatment with oral steroids are generally avoided except for the most difficult-to-control asthma because of the undesirable side effects that often develop with prolonged oral steroid treatment.
As a rough guide, we consider less than 20 milligrams abbreviated "mg" of prednisone a low dose, 20 to 30 mg a moderate dose, and 40 to 60 mg a high dose of oral steroids. When rapid relief from an asthma attack is needed, a high dose will often be recommended initially, followed by a gradual reduction in dose on successive days until the oral steroids are stopped: a "steroid taper. There is no single schedule of oral steroid dosing that is right for all asthma attacks in all patients.
Most often, we recommend taking the tablets altogether in the morning. Sometimes the steroid dose is divided up during the day and on occasion even given once daily in the evening. The beneficial effects of oral steroids are usually evident within several hours. Breathing becomes easier and wheezing, cough, mucus production, and chest tightness all gradually lessen. Other allergic diseases, such eczema and nasal congestion and drip, are also likely to be helped by the anti-inflammatory action of the oral steroids.
Many people also find that oral steroids, independent of their effect on breathing, give a powerful boost of energy—for a short while. Undesirable side effects of oral steroids are common, even during a short course. Any individual person may experience none, some, or all of these side effects, which generally go away quickly when the medication is stopped. These side effects include: stomach irritation "indigestion" , fluid retention causing a sense of bloating, hunger, sleeplessness, blurry vision, short temper, and difficulty concentrating.
Women may have their menstrual cycle become irregular for a brief while and may develop a vaginal yeast infection. Rare complications include loss of a sense of reality psychosis , triggering the onset of diabetes, and injury to the bone in a joint aseptic necrosis of a bone. When the steroid dose is being tapered or stopped, one may experience a different set of side effects. Bear with them; these side effects will go away in a short while. If taken for a long time months to years , daily oral steroids, especially in moderate to high doses, can cause many harmful side effects.
These complications of long-term use include cataracts of the eyes, thinning of the bones osteoporosis , weakness of the muscles myopathy , fragile skin with a tendency to bruise easily, hair loss, facial hair growth in women, puffy cheeks, a fatty bulge at the base of the back of the neck, and weight gain.

If you have serious worsening of asthma symptoms (an asthma attack), your doctor. Prednisone and other steroid drugs may be used to help control sudden and severe asthma attacks or in rare cases to treat long-term. At least on a short term basis, our results suggest that in stable mild or moderate adult asthmatic patients, who are corticosteroid free for.
