Intravaginal Administration

Vaginal insert (Intrarosa)
For intravaginal use only. Administer once daily at bedtime.
Use the applicators that comes with the package; each applicator is for a single-use only.
The patient should empty the bladder and wash hands before handling the vaginal insert and applicator.
Preparing applicator for insertion:
Remove 1 applicator from the package. Pull back on the plunger until it stops to activate the applicator; the applicator must be activated before use. Place the applicator on a clean surface.
Tear off 1 vaginal insert along the perforations from the 7-vaginal insert strip.
Slowly pull the plastic tabs on the vaginal insert away from each other while keeping the vaginal insert still between your fingers.
Carefully remove the vaginal insert from the plastic wrap. If a vaginal insert falls on an unsanitary surface, replace it with a new one.
Place the flat end of the vaginal insert into the open end of the activated applicator. The vaginal insert is now ready for insertion.
Insertion:
Hold the applicator between the thumb and middle finger. Leave the index (pointer) finger free to press the applicator plunger after the applicator is inserted into the vagina.
Select the position for insertion that is most comfortable; either lying down or standing.
Gently slide the vaginal insert end of the applicator into the vagina as far as it will comfortably go, but do not use force.
Press the applicator plunger with the index finger to release the vaginal insert. Remove the applicator and throw it away after use.
Wash hands after administration.

Hepatic Impairment

The effect of hepatic impairment has not been studied; it appears that no dosage adjustments are needed.

Renal Impairment

The effect of renal impairment has not been studied; it appears that no dosage adjustments are needed.

Abarelix: (Major) Concomitant use of androgens or estrogens with abarelix is relatively contraindicated, as both could counteract the therapeutic effect of abarelix.
Acarbose: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Acetaminophen; Aspirin, ASA; Caffeine: (Moderate) Prasterone, dehydroepiandrosterone, DHEA appears to have antiplatelet effects, which may prolong bleeding times. Because of these potential, varied effects on coagulation, patients receiving DHEA concurrently with aspirin, should be monitored for side effects or the need for dosage adjustments.
Acetaminophen; Aspirin: (Moderate) Prasterone, dehydroepiandrosterone, DHEA appears to have antiplatelet effects, which may prolong bleeding times.

Acetaminophen; Aspirin; Diphenhydramine: (Moderate) Prasterone, dehydroepiandrosterone, DHEA appears to have antiplatelet effects, which may prolong bleeding times. Because of these potential, varied effects on coagulation, patients receiving DHEA concurrently with aspirin, should be monitored for side effects or the need for dosage adjustments.
Albuterol; Budesonide: (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Alogliptin: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.

Alprazolam: (Major) Prasterone, dehydroepiandrosterone, DHEA may inhibit the metabolism of benzodiazepines (e.g., alprazolam, estazolam, midazolam) which undergo CYP3A4-mediated metabolism. In one study of elderly volunteers, half of the patients received DHEA 200 mg/day PO for 2 weeks, followed by a single dose of triazolam 0.25 mg. Triazolam clearance was reduced by close to 30% in the DHEA-pretreated patients vs. the control group; however, the effect of DHEA on CYP3A4 metabolism appeared to vary widely among subjects. While more study is needed, benzodiazepine-induced CNS sedation and other adverse effects might be increased in some individuals if DHEA is co-administered.
Anastrozole: (Major) Prasterone, dehydroepiandrosterone, DHEA is converted via hydrosteroid dehydrogenases and aromatase into androstenedione, testosterone, and estradiol by peripheral tissues. Prasterone or DHEA supplements should not be given concurrently with any aromatase inhibitors, as DHEA could interfere with the pharmacologic action of the aromatase inhibitor and compromise aromatase inhibitor effectiveness. Conversely, aromatase inhibitors (e.g., aminoglutethimide, anastrozole, exemestane, letrozole, testolactone, vorozole) could interfere with biotransformation of DHEA.
Anticoagulants: (Major) Prasterone (DHEA) is contraindicated for use in patients with active deep vein thrombosis, pulmonary embolism or history of these conditions. Prasterone is also contraindicated in patients with active arterial thromboembolic disease (for example, stroke and myocardial infarction), or a history of these conditions. Thus, patients receiving anticoagulation due to a history of these conditions are not candidates for prasterone treatment. DHEA is converted to androgens and estrogens within the human body and thus may affect hemostasis via androgenic or estrogenic effects. Estrogens increase the production of clotting factors VII, VIII, IX, and X. Androgens, such as testosterone, increase the synthesis of several anticoagulant and fibrinolytic proteins. Because of the potential effects on coagulation, patients receiving prasterone or DHEA concurrently with preventative anticoagulants (e.g., warfarin or heparin) or other platelet inhibitors, including aspirin, ASA should be monitored for side effects or the need for dosage adjustments.

Cetrorelix: (Major) Prasterone, dehydroepiandrosterone, DHEA is converted via hydrosteroid dehydrogenases and aromatase into androstenedione, testosterone, and estradiol by peripheral tissues. DHEA is a weak androgen that has complex hormonal effects. It is unclear what actions prasterone, dehydroepiandrosterone, DHEA would have on other exogenous hormonal regimens. It would seem prudent to not administer DHEA with infertility or hormonal cancer treatments such as GnRH analogs (cetrorelix, ganirelix, goserelin, histrelin, leuprolide, or triptorelin) since DHEA may theoretically interfere with these therapies.
Chlordiazepoxide: (Major) Prasterone, dehydroepiandrosterone, DHEA may inhibit the metabolism of benzodiazepines (e.g., alprazolam, estazolam, midazolam) which undergo CYP3A4-mediated metabolism.

Concurrent administration of androgens can increase the patient's response to epoetin alfa, reducing the amount required to treat anemia. Because adverse reactions have been associated with an abrupt increase in blood viscosity, this drug combination should be avoided, if possible. Further evaluation of this combination needs to be made.
Ertugliflozin: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Ertugliflozin; Metformin: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.

In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Estazolam: (Major) Prasterone, dehydroepiandrosterone, DHEA may inhibit the metabolism of benzodiazepines (e.g., alprazolam, estazolam, midazolam) which undergo CYP3A4-mediated metabolism. In one study of elderly volunteers, half of the patients received DHEA 200 mg/day PO for 2 weeks, followed by a single dose of triazolam 0.25 mg. Triazolam clearance was reduced by close to 30% in the DHEA-pretreated patients vs. the control group; however, the effect of DHEA on CYP3A4 metabolism appeared to vary widely among subjects. While more study is needed, benzodiazepine-induced CNS sedation and other adverse effects might be increased in some individuals if DHEA is co-administered.
Esterified Estrogens: (Moderate) Either additive or antagonistic effects could potentially occur if prasterone is combined with estrogen therapy.
Esterified Estrogens; Methyltestosterone: (Moderate) Either additive or antagonistic effects could potentially occur if prasterone is combined with estrogen therapy.

Etonogestrel; Ethinyl Estradiol: (Moderate) Either additive or antagonistic effects could potentially occur if prasterone is combined with estrogen therapy.
Exemestane: (Major) Prasterone, dehydroepiandrosterone, DHEA is converted via hydrosteroid dehydrogenases and aromatase into androstenedione, testosterone, and estradiol by peripheral tissues. Prasterone or DHEA supplements should not be given concurrently with any aromatase inhibitors, as DHEA could interfere with the pharmacologic action of the aromatase inhibitor and compromise aromatase inhibitor effectiveness. Conversely, aromatase inhibitors (e.g., aminoglutethimide, anastrozole, exemestane, letrozole, testolactone, vorozole) could interfere with biotransformation of DHEA.
Fludrocortisone: (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Flunisolide: (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Flurazepam: (Major) Prasterone, dehydroepiandrosterone, DHEA may inhibit the metabolism of benzodiazepines (e.g., alprazolam, estazolam, midazolam) which undergo CYP3A4-mediated metabolism. In one study of elderly volunteers, half of the patients received DHEA 200 mg/day PO for 2 weeks, followed by a single dose of triazolam 0.25 mg.

Fondaparinux: (Major) Prasterone (DHEA) is contraindicated for use in patients with active deep vein thrombosis, pulmonary embolism or history of these conditions. Prasterone is also contraindicated in patients with active arterial thromboembolic disease (for example, stroke and myocardial infarction), or a history of these conditions. Thus, patients receiving anticoagulation due to a history of these conditions are not candidates for prasterone treatment. DHEA is converted to androgens and estrogens within the human body and thus may affect hemostasis via androgenic or estrogenic effects. Estrogens increase the production of clotting factors VII, VIII, IX, and X. Androgens, such as testosterone, increase the synthesis of several anticoagulant and fibrinolytic proteins. Because of the potential effects on coagulation, patients receiving prasterone or DHEA concurrently with preventative anticoagulants (e.g., warfarin or heparin) or other platelet inhibitors, including aspirin, ASA should be monitored for side effects or the need for dosage adjustments.
Formoterol; Mometasone: (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Ganirelix: (Major) Prasterone, dehydroepiandrosterone, DHEA is converted via hydrosteroid dehydrogenases and aromatase into androstenedione, testosterone, and estradiol by peripheral tissues. DHEA is a weak androgen that has complex hormonal effects. It is unclear what actions prasterone, dehydroepiandrosterone, DHEA would have on other exogenous hormonal regimens. It would seem prudent to not administer DHEA with infertility or hormonal cancer treatments such as GnRH analogs (cetrorelix, ganirelix, goserelin, histrelin, leuprolide, or triptorelin) since DHEA may theoretically interfere with these therapies.
Glipizide; Metformin: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements.

Monitor blood glucose and HbA1C when these drugs are used together.
Methoxy polyethylene glycol-epoetin beta: (Moderate) Androgens are known to stimulate erythropoiesis. Despite the fact that endogenous generation of erythropoietin is depressed in patients with chronic renal failure, other tissues besides the kidney can synthesize erythropoietin, albeit in small amounts. Concurrent administration of androgens can increase the patient's response to MPG-epoetin beta, reducing the amount required to treat anemia. Because adverse reactions have been associated with an abrupt increase in blood viscosity, this drug combination should be avoided, if possible. Further evaluation of this combination needs to be made.

The mechanism of action of prasterone in postmenopausal women with vulvar and vaginal atrophy is not fully established. Prasterone is a synthetic steroid that is chemically identical to the naturally-occurring pro-hormone 5-dehydroepiandrosterone (5-DHEA), a pro-hormone secreted by the adrenal cortex, gonads and brain tissue. Exogenous prasterone is converted into active estrogens in the same manner as endogenous prasterone or DHEA. Endogenous DHEA is synthesized by the conversion of cholesterol via CYP11A1 to pregnenolone, followed by CYP17 conversion to DHEA and then to DHEAS via dehydroepiandrosterone sulfatransferase. The synthesis of DHEA occurs exclusively in the adrenal cortex in women. In females, DHEA serum levels are high in neonates right after birth, rapidly fall within 5 months, then begin to rise at the age of 7 years. Endogenous DHEA concentration then peaks again in females at roughly the 20th and 40th year of life. DHEA levels decline steadily after the fifth decade.

Prasterone is administered intravaginally. Exogenous prasterone is metabolized in the same manner as endogenous prasterone. Human steroidogenic enzymes such as hydroxysteroid dehydrogenases, 5-alpha-reductases, and aromatases transform prasterone into androgens and estrogens.
 
Affected cytochrome P450 (CYP450) isoenzymes and drug transporters: Data not available.

Other Route(s)

In a clinical study, administration of prasterone vaginal insert once daily for 7 days resulted in a mean prasterone Cmax and exposure (AUC 0 to 24) at Day 7 of 4.4 ng/mL and 56.2 ng x hour/mL, respectively, which were significantly higher than those in the group treated with placebo. The Cmax and AUC of the metabolites testosterone and estradiol were also slightly higher in women treated with prasterone compared to those receiving placebo.

Pregnancy

Prasterone is only indicated in postmenopausal women. There are no data with prasterone use in pregnancy regarding any drug-associated risks. Animal reproduction studies have not been conducted with prasterone. Studies of the role of endogenous fetal and maternal prasterone (DHEA) in pregnancy indicate that the ratio of DHEA or DHEAS to other hormones in the serum or placenta may influence the processes of fetal development, parturition, and labor. Endogenous DHEA and DHEAS appear to be important in the functional development of the adrenal cortex and other endocrine activities in the fetus; it is assumed that exogenous DHEA supplementation to a pregnant woman could potentially have deleterious effects on fetal development or viability. The androgenic effects of DHEA could potentially result in masculinization of a female fetus. Do not administer prasterone to a pregnant woman.

Prasterone is only indicated in postmenopausal women. There is no information on the presence of prasterone in human milk, the effects on the breastfed infant, or the effects on milk production. Most hormones are excreted in breast milk. Like other androgenic hormones, it is possible that prasterone could inhibit lactation. Due to the potential harm to a nursing infant, prasterone use should be avoided during breast-feeding.
