How to use
Individualize the dose, using the lowest possible dosage. (2.1) • The recommended starting replacement dosage is 8 to 10 mg/m2 daily. Higher doses may be needed based on patient’s age and symptoms of the disease. Use of lower starting doses may be sufficient in patients with residual but decreased endogenous cortisol production. (2.1) • Round the dose to the nearest 0.5 mg or 1 mg. More than one capsule may be needed to supply the required dose. (2.1) • Divide the total daily dose in 3 doses and administer 3 times daily. Older patients may have their daily dose divided by 2 and administered twice daily. (2.1) • When switching from other oral hydrocortisone formulations, use the same total daily hydrocortisone dosage. If symptoms of adrenal insufficiency occur, increase total daily dosage. (2.2) • ALKINDI SPRINKLE are oral granules contained within capsules. Do not swallow the capsule. Do not chew or crush the granules. (2.3) • See the Full Prescribing Information for detailed administration instructions. (2.3) 2.1 Dosage Information Individualize the dose for each patient, using the lowest possible dosage. The recommended starting replacement dosage is 8 to 10 mg/m 2 /day daily. Higher doses may be needed based on patient’s age and symptoms of the disease. Use of lower starting doses may be sufficient in patients with residual but decreased endogenous cortisol production.…

Warnings
Important safety information
Adrenal Crisis: Undertreatment, sudden discontinuation of therapy, or switching from another oral hydrocortisone formulation may lead to adrenocortical insufficiency, adrenal crisis and death. Adrenal crisis may also be induced by stress events such as infections or surgery. Increase the dose during periods of stress. Switch patients who are vomiting, severely ill or unable to take oral medications to parenteral corticosteroid formulations. (5.1) Immunosuppression and Increased Risk of Infection with Use of a Dosage Greater Than Replacement : Use of a greater than replacement dosage can suppress the immune system and increase the risks of new infections or exacerbation of latent infections with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic infections. Monitor patients for signs and symptoms of infections. (5.2) Growth Retardation: Long-term use in excessive doses may cause growth retardation. Use the minimum dosage of ALKINDI SPRINKLE to achieve desired clinical response and monitor the patient’s growth. (5.3) Cushing’s Syndrome Due to Use of Excessive Doses of Corticosteroids: Prolonged use with supraphysiologic doses may cause Cushing’s syndrome. Monitor patients for signs and symptoms of Cushing’s syndrome every 6 months, pediatric patients under one year of age may require more frequent monitoring. (5.4) Decrease in Bone Mineral Density: Corticosteroids decrease bone formation and increase bone resorption which may lead to inhibition of bone growth and development of osteoporosis. Use the minimum dosage of ALKINDI SPRINKLE to achieve desired clinical response. (5.5) Psychiatric Adverse Reactions: Use may be associated with severe psychiatric adverse reactions such as euphoria, mania, psychosis with hallucinations and delirium or depression. Symptoms typically emerge within a few days or weeks of starting the treatment. Most reactions resolve after either dose reduction or withdrawal, although specific treatment may be necessary. Monitor patients for behavioral and mood disturbances during treatment. Instruct caregivers and/or patients to seek medical advice if psychiatric symptoms develop. (5.6) Ophthalmic Adverse Reactions: Cataracts, glaucoma and central serous chorioretinopathy have been reported with prolonged use of high doses. Monitor patients for blurred vision or other visual disturbances and if they occur, refer them to an ophthalmologist. (5.7) Gastrointestinal Adverse Reactions: Increased risk in patients with certain gastrointestinal disorders. Signs and symptoms may be masked. (5.8) 5.1 Adrenal Crisis Undertreatment with ALKINDI SPRINKLE or sudden discontinuation of therapy with ALKINDI SPRINKLE may lead to adrenocortical insufficiency, adrenal crisis, and death. Adrenal crisis may also be induced by stress events such as infections or surgery when patients require higher doses of corticosteroids. Symptoms of adrenocortical insufficiency include poor feeding, fatigue, low muscle tone, joint pain, nausea, vomiting, hypoglycemia, low blood pressure and electrolyte disturbances. Increase the dosage of ALKINDI SPRINKLE during periods of stress (infections, surgery). Switch patients who are vomiting, severely ill or unable to take oral medications to parenteral corticosteroid formulations without delay. Once the patient recovers, gradually reduce the steroid dosage used during the acute event. When switching patients to ALKINDI SPRINKLE from another oral hydrocortisone formulation, consider the potential for dosing inaccuracy if the other oral hydrocortisone formulation has been manipulated (e.g., split or crushed tablets, compounded formulations). Manipulation of oral hydrocortisone formulations may result in a relative difference in hydrocortisone exposure when using the same dosage to initiate ALKINDI SPRINKLE treatment. Closely monitor patients after switching to ALKINDI SPRINKLE to ensure ALKINDI SPRINKLE is providing the same level of hydrocortisone exposure as the previously used oral hydrocortisone formulation. If symptoms of adrenal insufficiency occur, increase the total daily dosage of ALKINDI SPRINKLE. 5.2 Immunosuppression and Increased Risk of Infection with Use of a Dosage Greater Than Replacement Use of the recommended dosage of ALKINDI SPRINKLE [see Dosage and Administration (2.1, 2.2)] as a replacement therapy in pediatric patients with adrenocortical insufficiency is not expected to cause immunosuppression or increase the risk of infection. The use of a greater than replacement dosage can suppress the immune system and increase the risk of infection with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic pathogens. The use of ALKINDI SPRINKLE at greater than replacement dosage can: • Reduce resistance to new infections • Exacerbate existing infections • Increase the risk of disseminated infections • Increase the risk of reactivation or exacerbation of latent infections • Mask some signs of infection Infections associated with the use of corticosteroids at a greater than replacement dosage range from mild to severe or fatal, and the rate of infectious complications increases with increasing corticosteroid dosages. Monitor for the development of infection and consider ALKINDI SPRINKLE dosage reduction as needed. 5.3 Growth Retardation Long-term use of corticosteroids in excessive doses may cause growth retardation in pediatric patients. Historical cohorts of adults treated from childhood for congenital adrenal hyperplasia have been found to have growth retardation. Effects on linear growth are less likely when using corticosteroids as replacement therapy. Use the minimum dosage of ALKINDI SPRINKLE to achieve desired clinical response and monitor the patient’s growth. 5.4 Cushing’s Syndrome Due to Use of Excessive Doses of Corticosteroids Prolonged use of corticosteroids in supraphysiologic doses may cause Cushing’s syndrome. Symptoms and signs of Cushing’s syndrome include weight gain, decreased height velocity, hyperglycemia, hypertension, edema, easy bruising, muscle weakness, red round face, depression or mood swings. Monitor patients for signs and symptoms of Cushing’s syndrome every 6 months; pediatric patients under one year of age may require more frequent monitoring, e.g., every 3 to 4 months. 5.5 Decrease in Bone Mineral Density Corticosteroids decrease bone formation and increase bone resorption which may lead to development of osteoporosis. Historical cohorts of adults treated from childhood for congenital adrenal hyperplasia have been found to have reduced bone mineral density and increased fracture rates. Use the minimum dosage of ALKINDI SPRINKLE to achieve desired clinical response. 5.6 Psychiatric Adverse Reactions Corticosteroid use may be associated with severe psychiatric adverse reactions. Euphoria, mania, psychosis with hallucinations and delirium or depression have been seen in patients at replacement doses of hydrocortisone [see Adverse Reactions ( 6 )] . Symptoms typically emerge within a few days or weeks of starting the treatment. Risks may be higher with high doses, although dose levels do not allow prediction of the onset, type, severity or duration of reactions. Most reactions resolve after either dose reduction or withdrawal, although specific treatment may be necessary. Monitor patients for behavioral and mood disturbances during treatment with ALKINDI SPRINKLE. Instruct caregivers and/or patients to seek medical advice if psychiatric symptoms develop. 5.7 Ophthalmic Adverse Reactions Ophthalmic effects, such as cataract, glaucoma or central serous chorioretinopathy have been reported with prolonged use of corticosteroids in high doses. Monitor patients for blurred vision or other visual disturbances. If patients develop ophthalmic adverse reactions, refer them to an ophthalmologist for further evaluation. 5.8 Gastrointestinal Adverse Reactions There is an increased risk of gastrointestinal perforation in patients with certain…

Interactions
Table 2 Drug Interactions with ALKINDI SPRINKLE CYP3A4 Inhibitors Clinical Impact: Hydrocortisone is metabolized by cytochrome P450 3A4 (CYP3A4). Concomitant administration of inhibitors of CYP3A4 may lead to increases in serum concentrations of ALKINDI SPRINKLE and increase the risk of adverse reactions associated with the use of excessive doses. Intervention: Concomitant use of CYP3A4 inhibitors may require a decrease in the ALKINDI SPRINKLE dose. Examples: Anti-fungals: itraconazole, posaconazole, voriconazole Antibiotics: erythromycin and clarithromycin Antiretrovirals: ritonavir Grapefruit juice CYP3A4 Inducers Clinical Impact: Hydrocortisone is metabolized by cytochrome P450 3A4 (CYP3A4). Concomitant administration of inducers of CYP3A4 may lead to decreases in serum concentrations of ALKINDI SPRINKLE and increase the risk of adverse reactions, including adrenal crisis. Intervention: Concomitant use of CYP3A4 inducers may require an increase in the ALKINDI SPRINKLE dose. Examples: Anticonvulsants: phenytoin, carbamazepine and oxcarbazepine Antibiotics: rifampicin and rifabutin Barbiturates: phenobarbital and primidone Antiretrovirals: efavirenz and nevirapine Estrogen and Estrogen Containing Products Clinical Impact: Oral estrogen and estrogen-containing oral contraceptives may interact with hydrocortisone by increasing serum cortisol-binding globulin (CBG) concentration. Concomitant use may reduce the efficacy of ALKINDI SPRINKLE by binding and delaying or preventing absorption. Intervention: Concomitant use of estrogen/estrogen containing products may require an increase in the ALKINDI SPRINKLE dose. Antidiabetic Agents Clinical Impact: Corticosteroids in supraphysiologic doses may increase blood glucose concentrations. Intervention: Use of ALKINDI SPRINKLE in supraphysiologic doses may require a dose adjustment of antidiabetic agents. Anticoagulant Agents Clinical Impact: Concomitant use of warfarin and corticosteroids usually results in inhibition of response to warfarin, although there have been some conflicting reports. Intervention: Monitor coagulation indices in patients receiving ALKINDI SPRINKLE and concomitant warfarin to maintain the desired anticoagulant effect. Cyclosporine Clinical Impact: Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with concurrent use. Intervention: Monitor patients receiving ALKINDI SPRINKLE and concomitant cyclosporine. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) Clinical Impact: Concomitant use of NSAIDs and corticosteroids increases the risk of gastrointestinal adverse reactions. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids; this could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when corticosteroid is withdrawn. Intervention: Monitor patients receiving ALKINDI SPRINKLE and concomitant NSAIDs. CYP3A4 Inhibitors : concomitant administration may require a decrease in the ALKINDI SPRINKLE dose. ( 7 ) CYP3A4 Inducers : concomitant administration may require an increase in the ALKINDI SPRINKLE dose. ( 7 ) Estrogen and Estrogen Containing Products : concomitant administration may require an increase in the ALKINDI SPRINKLE dose. ( 7 ) Antidiabetic agents: excessive doses may increase blood glucose concentrations. Dose adjustment of antidiabetic agents may be required. ( 7 ) NSAIDs: concomitant administration increases risk of gastrointestinal adverse reactions. ( 7 ) See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling (Medication Guide).

How long does Hydrocortisone stay in your body?
The elimination half-life of hydrocortisone is about 1.5 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the plasma (terminal) elimination half-life; the FDA label states "The terminal half-life of hydrocortisone is about 1.5 hours following intravenous and oral dosing of hydrocortisone tablets" in healthy adults, so roughly 90% of a dose clears within about 8 hours and nearly all within ~12 hours. Hydrocortisone is not a prodrug, but its half-life measures how fast the drug leaves the blood, not how long its effects last: as a short-acting glucocorticoid its biological (tissue) effect on the body persists well beyond blood clearance, and this short plasma half-life is why oral replacement is usually dosed 2-3 times a day. Because hydrocortisone is metabolized in the liver, significant liver impairment can slow clearance; the label does not give a specific half-life adjustment for age, kidney, or liver function. Half-life is not the same as a drug-test detection window.
