Compounded Exemestane

The primary FDA-approved indication for exemestane is adjuvant therapy for hormone-receptor-positive early breast cancer in postmenopausal women — typically 25 mg daily, switched in after 2–3 years of tamoxifen, or used as extended therapy after initial anastrozole or letrozole. It's also used for metastatic breast cancer that has progressed on other endocrine therapy.

Because exemestane is a steroidal (irreversible) aromatase inhibitor — structurally similar to androstenedione — some men on TRT use it off-label when non-steroidal AIs (anastrozole, letrozole) cause excessive estradiol crash symptoms like joint pain and dry skin. Exemestane's mild androgenic metabolites may preserve a more favorable side-effect profile in that context. It also appears in post-cycle therapy protocols in anabolic-steroid-using populations, though that use is outside mainstream medical practice.

Commercial exemestane is available only as a 25 mg tablet. That works for standard oncology dosing but is limiting for three patient groups.

First, patients with documented sensitivities to the tablet's inactive ingredients (mannitol, crospovidone, magnesium stearate, polysorbate 80, simethicone, hypromellose, and titanium dioxide) benefit from dye-free, filler-minimized compounded capsules. Second, patients who cannot swallow tablets — typical in advanced oncology care — need liquid suspensions or sublingual troches. Third, off-label users (TRT, post-cycle) typically titrate at lower doses (6.25 mg or 12.5 mg) and cannot reliably split scored or unscored 25 mg tablets into consistent fractions.

Compounded exemestane capsules at exact sub-25 mg strengths solve the splitting problem and deliver consistent doses that match protocol titration.

Oncology dosing is straightforward: 25 mg once daily, typically after a meal to improve absorption. Exemestane is taken as long-term adjuvant therapy (5 years total endocrine therapy is the standard framework) and irreversibly inactivates aromatase, so once-daily dosing is sufficient regardless of timing within the day.

Off-label TRT protocols typically use 12.5 mg every other day or 12.5 mg three times weekly, adjusted based on estradiol and symptom response. Post-cycle protocols may use 25 mg every other day for a defined taper period. Off-label use is prescriber-dependent; your clinician sets the protocol. Because exemestane is an irreversible inhibitor, the pharmacodynamic effect outlasts the drug's half-life, which matters when comparing dosing intervals to reversible AIs like anastrozole.

Compounded exemestane capsules typically run $45–$95 for a 30-day supply at standard 25 mg dosing, or $30–$70 at sub-25 mg strengths. Sublingual troches are $50–$110 per 30-day supply. Oral suspensions are $55–$120 per 30-day supply.

Commercial generic exemestane 25 mg tablets are usually cheaper per pill through insurance or GoodRx — often $30–$60 for a 30-day supply. Compounding is the right choice when you need dye-free formulations, a non-standard strength, or an alternative route because you can't swallow tablets.
