What is Rapamune?
From the FDA label:Sirolimus is an mTOR inhibitor immunosuppressive agent. Sirolimus is a macrocyclic lactone produced by Streptomyces hygroscopicus . The chemical name of sirolimus (also known as rapamycin) is (3 S ,6 R ,7 E ,9 R ,10 R ,12 R ,14 S ,15 E ,17 E ,19 E ,21 S ,23 S ,26 R ,27 R ,34a S )-9,10,12,13,14,21,22,23,24,25,26,27,32,33,34, 34a-hexadecahydro-9,27-dihydroxy-3-[(1 R )-2-[(1 S ,3 R ,4 R )-4-hydroxy-3-methoxycyclohexyl]-1-methylethyl]-10,21-dimethoxy-6,8,12,14,20,26-hexamethyl-23,27-epoxy-3 H -pyrido[2,1-c][1,4] oxaazacyclohentriacontine-1,5,11,28,29 (4 H ,6 H ,31 H )-pentone. Its molecular formula is C 51 H 79 NO 13 and its molecular weight is 914.2. The structural formula of sirolimus is illustrated as follows. Sirolimus is a white to off-white powder and is insoluble in water, but freely soluble in benzyl alcohol, chloroform, acetone, and acetonitrile. Sirolimus is available for administration as an oral solution containing 1 mg/mL sirolimus. The inactive ingredients in sirolimus oral solution are Phosal 50 PG ® (phosphatidylcholine, propylene glycol, mono- and di-glycerides, ethanol, soy fatty acids, and ascorbyl palmitate) and polysorbate 80. Sirolimus oral solution contains 1.5% – 2.5% ethanol. Chemical Structure

FDA Boxed Warning (the FDA’s most serious warning)
Boxed (black-box) warning — from the FDA label
IMMUNOSUPPRESSION, USE IS NOT RECOMMENDED IN LIVER OR LUNG TRANSPLANT PATIENTS • Increased susceptibility to infection and the possible development of lymphoma and other malignancies may result from immunosuppression Increased susceptibility to infection and the possible development of lymphoma may result from immunosuppression. Only physicians experienced in immunosuppressive therapy and management of renal transplant patients should use sirolimus for prophylaxis of organ rejection in patients receiving renal transplants. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient [ see Warnings and Precautions (5.1) ] . • The safety and efficacy of sirolimus as immunosuppressive therapy have not been established in liver or lung transplant patients, and therefore, such use is not recommended [ see Warnings and Precautions (5.2 , 5.3) ] . • Liver Transplantation – Excess Mortality, Graft Loss, and Hepatic Artery Thrombosis (HAT) The use of sirolimus in combination with tacrolimus was associated with excess mortality and graft loss in a study in de novo liver transplant patients. Many of these patients had evidence of infection at or near the time of death. In this and another study in de novo liver transplant patients, the use of sirolimus in combination with cyclosporine or tacrolimus was associated with an increase in HAT; most cases of HAT occurred within 30 days post-transplantation and most led to graft loss or death [ see Warnings and Precautions (5.2) ]. • Lung Transplantation – Bronchial Anastomotic Dehiscence Cases of bronchial anastomotic dehiscence, most fatal, have been reported in de novo lung transplant patients when sirolimus has been used as part of an immunosuppressive regimen [ see Warnings and Precautions (5.3) ].

Only physicians experienced in immunosuppressive therapy and management of renal transplant patients should use sirolimus for prophylaxis of organ rejection in patients receiving renal transplants. • The safety and efficacy of sirolimus as immunosuppressive therapy have not been established in liver or lung transplant patients, and therefore, such use is not recommended ( 5.2 , 5.3 ). o Liver Transplantation – Excess mortality, graft loss, and hepatic artery thrombosis ( 5.2 ). o Lung Transplantation – Bronchial anastomotic dehiscence ( 5.3 ).
Warnings
Important safety information
Hypersensitivity Reactions ( 5.4 ) • Angioedema ( 5.5 ) • Fluid Accumulation and Impairment of Wound Healing ( 5.6 ) • Hyperlipidemia ( 5.7 ) • Decline in Renal Function ( 5.8 ) • Proteinuria ( 5.9 ) • Latent Viral Infections ( 5.10 ) • Interstitial Lung Disease/Non-Infectious Pneumonitis ( 5.11 ) • De Novo Use Without Cyclosporine ( 5.12 ) • Increased Risk of Calcineurin Inhibitor-Induced Hemolytic Uremic Syndrome/ Thrombotic Thrombocytopenic Purpura/ Thrombotic Microangiopathy ( 5.13 ). • Embryo-Fetal Toxicity: Can cause fetal harm. Use of highly effective contraception is recommended for females of reproductive potential during treatment and for 12 weeks after final dose of sirolimus ( 5.15 , 8.1 ). • Male Infertility: Azoospermia or oligospermia may occur ( 5.16 , 13.1 ) • Immunizations: Avoid live vaccines ( 5.19 ) 5.1 Increased Susceptibility to Infection and the Possible Development of Lymphoma Increased susceptibility to infection and the possible development of lymphoma and other malignancies, particularly of the skin, may result from immunosuppression. The rates of lymphoma/lymphoproliferative disease observed in Studies 1 and 2 were 0.7–3.2% (for sirolimus-treated patients) versus 0.6–0.8% (azathioprine and placebo control) [ see Adverse Reactions (6.1) and (6.2) ]. Oversuppression of the immune system can also increase susceptibility to infection, including opportunistic infections such as tuberculosis, fatal infections, and sepsis. Only physicians experienced in immunosuppressive therapy and management of organ transplant patients should use sirolimus for prophylaxis of organ rejection in patients receiving renal transplants. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient. 5.2 Liver Transplantation – Excess Mortality, Graft Loss, and Hepatic Artery Thrombosis The safety and efficacy of sirolimus as immunosuppressive therapy have not been established in liver transplant patients; therefore, such use is not recommended. The use of sirolimus has been associated with adverse outcomes in patients following liver transplantation, including excess mortality, graft loss and hepatic artery thrombosis (HAT). In a study in de novo liver transplant patients, the use of sirolimus in combination with tacrolimus was associated with excess mortality and graft loss (22% in combination versus 9% on tacrolimus alone). Many of these patients had evidence of infection at or near the time of death. In this and another study in de novo liver transplant patients, the use of sirolimus in combination with cyclosporine or tacrolimus was associated with an increase in HAT (7% in combination versus 2% in the control arm); most cases of HAT occurred within 30 days post-transplantation, and most led to graft loss or death. In a clinical study in stable liver transplant patients 6–144 months post-liver transplantation and receiving a CNI-based regimen, an increased number of deaths was observed in the group converted to a sirolimus-based regimen compared to the group who was continued on a CNI-based regimen, although the difference was not statistically significant (3.8% versus 1.4%) [ see Clinical Studies (14.5) ]. 5.3 Lung Transplantation – Bronchial Anastomotic Dehiscence Cases of bronchial anastomotic dehiscence, most fatal, have been reported in de novo lung transplant patients when sirolimus has been used as part of an immunosuppressive regimen. The safety and efficacy of sirolimus as immunosuppressive therapy have not been established in lung transplant patients; therefore, such use is not recommended. 5.4 Hypersensitivity Reactions Hypersensitivity reactions, including anaphylactic/anaphylactoid reactions, angioedema, exfoliative dermatitis and hypersensitivity vasculitis, have been associated with the administration of sirolimus [ see Adverse Reactions (6.7) ]. 5.5 Angioedema Sirolimus has been associated with the development of angioedema. The concomitant use of sirolimus with other drugs known to cause angioedema, such as angiotensin-converting enzyme (ACE) inhibitors, may increase the risk of developing angioedema. Elevated sirolimus levels (with/without concomitant ACE inhibitors) may also potentiate angioedema [ see Drug Interactions (7.2) ]. In some cases, the angioedema has resolved upon discontinuation or dose reduction of sirolimus. 5.6 Fluid Accumulation and Impairment of Wound Healing There have been reports of impaired or delayed wound healing in patients receiving sirolimus, including lymphocele and wound dehiscence [ see Adverse Reactions (6.1) ]. Mammalian target of rapamycin (mTOR) inhibitors such as sirolimus have been shown in vitro to inhibit production of certain growth factors that may affect angiogenesis, fibroblast proliferation, and vascular permeability. Lymphocele, a known surgical complication of renal transplantation, occurred significantly more often in a dose-related fashion in patients treated with sirolimus [ see Adverse Reactions (6.1) ]. Appropriate measures should be considered to minimize such complications. Patients with a body mass index (BMI) greater than 30 kg/m 2 may be at increased risk of abnormal wound healing based on data from the medical literature. There have also been reports of fluid accumulation, including peripheral edema, lymphedema, pleural effusion, ascites, and pericardial effusions (including hemodynamically significant effusions and tamponade requiring intervention in children and adults), in patients receiving sirolimus. 5.7 Hyperlipidemia Increased serum cholesterol and triglycerides requiring treatment occurred more frequently in patients treated with sirolimus compared with azathioprine or placebo controls in Studies 1 and 2 [ see Adverse Reactions (6.1) ]. There were increased incidences of hypercholesterolemia (43–46%) and/or hypertriglyceridemia (45–57%) in patients receiving sirolimus compared with placebo controls (each 23%). The risk/benefit should be carefully considered in patients with established hyperlipidemia before initiating an immunosuppressive regimen including sirolimus. Any patient who is administered sirolimus should be monitored for hyperlipidemia. If detected, interventions such as diet, exercise, and lipid-lowering agents should be initiated as outlined by the National Cholesterol Education Program guidelines. In clinical trials of patients receiving sirolimus plus cyclosporine or sirolimus after cyclosporine withdrawal, up to 90% of patients required treatment for hyperlipidemia and hypercholesterolemia with anti-lipid therapy (e.g., statins, fibrates). Despite anti-lipid management, up to 50% of patients had fasting serum cholesterol levels >240 mg/dL and triglycerides above recommended target levels. The concomitant administration of sirolimus and HMG-CoA reductase inhibitors resulted in adverse reactions such as CPK elevations (3%), myalgia (6.7%) and rhabdomyolysis (<1%). In these trials, the number of patients was too small and duration of follow-up too short to evaluate the long-term impact of sirolimus on cardiovascular mortality. During sirolimus therapy with or without cyclosporine, patients should be monitored for elevated lipids, and patients administered an HMG-CoA reductase inhibitor and/or fibrate should be monitored for the possible development of rhabdomyolysis and other adverse effects, as described in the respective labeling for these agents. 5.8 Decline in Renal Function Renal function should be closely monitored during the co-administration of sirolimus with cyclosporine, because long-term administration of the combination has been associated with deterioration of renal function. Patients treated with cyclosporine and sirolimus were noted to have higher serum creatinine levels and lower glomerular filtration rates compared with patients…
Who should not take Rapamune
Sirolimus is contraindicated in patients with a hypersensitivity to sirolimus [ see Warnings and Precautions (5.4) ]. Hypersensitivity to sirolimus ( 4 )
Overdose — what happens if you take too much
Reports of overdose with sirolimus have been received; however, experience has been limited. In general, the adverse effects of overdose are consistent with those listed in the adverse reactions section [ see Adverse Reactions (6) ]. General supportive measures should be followed in all cases of overdose. Based on the low aqueous solubility and high erythrocyte and plasma protein binding of sirolimus, it is anticipated that sirolimus is not dialyzable to any significant extent. In mice and rats, the acute oral LD 50 was greater than 800 mg/kg.

Interactions
Sirolimus is known to be a substrate for both cytochrome P-450 3A4 (CYP3A4) and p-glycoprotein (P-gp). Inducers of CYP3A4 and P-gp may decrease sirolimus concentrations whereas inhibitors of CYP3A4 and P-gp may increase sirolimus concentrations. • Avoid concomitant use with strong CYP3A4/P-gp inducers or strong CYP3A4/P-gp inhibitors that decrease or increase sirolimus concentrations ( 7.4 , 12.3 ). • Therapeutic drug monitoring and dose reduction for sirolimus should be considered when sirolimus is co-administered with cannabidiol ( 5.21 , 7.5 ). • See full prescribing information for complete list of clinically significant drug interactions ( 12.3 ). 7.1 Use with Cyclosporine Cyclosporine, a substrate and inhibitor of CYP3A4 and P-gp, was demonstrated to increase sirolimus concentrations when co-administered with sirolimus. In order to diminish the effect of this interaction with cyclosporine, it is recommended that sirolimus be taken 4 hours after administration of cyclosporine oral solution (MODIFIED) and/or cyclosporine capsules (MODIFIED). If cyclosporine is withdrawn from combination therapy with sirolimus, higher doses of sirolimus are needed to maintain the recommended sirolimus trough concentration ranges [ see Dosage and Administration (2.2) , Clinical Pharmacology (12.3) ]. 7.2 Strong Inducers and Strong Inhibitors of CYP3A4 and P-gp Avoid concomitant use of sirolimus with strong inducers (e.g., rifampin, rifabutin) and strong inhibitors (e.g., ketoconazole, voriconazole, itraconazole, erythromycin, telithromycin, clarithromycin) of CYP3A4 and P-gp. Alternative agents with lesser interaction potential with sirolimus should be considered [ see Warnings and Precautions (5.20) , Clinical Pharmacology (12.3) ]. 7.3 Grapefruit Juice Because grapefruit juice inhibits the CYP3A4-mediated metabolism of sirolimus, it must not be taken with or be used for dilution of sirolimus [ see Dosage and Administration (2.9) , Drug Interactions (7.3) , Clinical Pharmacology (12.3) ]. 7.4 Weak and Moderate Inducers or Inhibitors of CYP3A4 and P-gp Exercise caution when using sirolimus with drugs or agents that are modulators of CYP3A4 and P-gp. The dosage of sirolimus and/or the co-administered drug may need to be adjusted [ see Clinical Pharmacology (12.3) ]. • Drugs that could increase sirolimus blood concentrations: Bromocriptine, cimetidine, cisapride, clotrimazole, danazol, diltiazem, fluconazole, letermovir, protease inhibitors (e.g., HIV and hepatitis C that include drugs such as ritonavir, indinavir, boceprevir, and telaprevir), metoclopramide, nicardipine, troleandomycin, verapamil • Drugs and other agents that could decrease sirolimus concentrations: Carbamazepine, phenobarbital, phenytoin, rifapentine, St. John's Wort ( Hypericum perforatum ) • Drugs with concentrations that could increase when given with sirolimus: Verapamil. 7.5 Cannabidiol The blood levels of sirolimus may increase upon concomitant use with cannabidiol. When cannabidiol and sirolimus are co-administered, closely monitor for an increase in sirolimus blood levels and for adverse reactions suggestive of sirolimus toxicity. A dose reduction of sirolimus should be considered as needed when sirolimus is co-administered with cannabidiol [ see Dosage and Administration (2.5) , Warnings and Precautions (5.21) ].

Frequently asked questions
- What does Rapamune treat?
- Rapamune (Sirolimus) may be used to treat lymphangioleiomyomatosis, perivascular epithelioid cell neoplasms, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
- How does Rapamune work?
- Rapamune is a kinase inhibitor. Kinase inhibitors block protein kinases, the enzymes that relay 'grow and divide' signals inside cells. By shutting down the overactive kinase signals that a tumor depends on, they help slow or stop cancer cells from multiplying.
- How much does Rapamune cost?
- Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $48.61 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
- Is there a coupon or discount for Rapamune?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Rapamune. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
