How Does Femara Work?

Femara provides anti-estrogen effects through competitive aromatase inhibition:

1. Aromatase Inhibition: Competitively binds to aromatase enzyme complex
2. Estrogen Synthesis Blockade: Inhibits conversion of androgens to estrogen throughout the body
3. Estrogen Suppression: Reduces circulating estrogen levels by 97-99%
4. Tumor Growth Prevention: Suppresses estrogen-dependent tumor cell proliferation

Femara Side Effects and Warnings

Common side effects include hot flashes, fatigue, joint pain, headache, nausea, and increased sweating. Bone pain and arthralgia are frequently reported.

Serious Considerations

1. Osteoporosis Risk: Accelerates bone mineral density loss – regular bone monitoring required
2. Cardiovascular Events: Increased incidence of hypercholesterolemia and cardiovascular events
3. Hepatic Impairment: Use with caution in patients with severe liver dysfunction
4. Drug Interactions: Avoid concomitant use with estrogen-containing therapies
5. Pregnancy Risk: Contraindicated in pregnant and premenopausal women
