Yes it is advisable to wean off steroids slowly so that body gets accustomed to low doses. You can consume turmeric in diet as Golden Paste. Start with 1/4 tsp and increase gradually to 1-2 tsp 2-3 times a day or how it suits you. Avoid taking it close to other medications. Curcumin works well with steroids.
Many users have reported that its easier to go off steroids when taking turmeric. But you should consult a doctor about this.
Corticosteroids and long-acting bronchodilators are also available in combinations for ease of use and efficacy. There is evidence that use of long-acting bronchodilators without an inhaled corticosteroid increases the risk of death during an asthma attack, which makes combination metered dose inhaler medications more popular. Brand names available for metered dose inhalers combining both a steroid and bronchodilator are Advair and Symbicort. Because of the corticosteroid component, these inhalers should not be discontinued suddenly without your Physician’s advice.
