Its okay: One missed dose will have little significance. Like most drugs, it stays in your system for a while and the effects/benefits last beyond the dose taken. Studies have shown that even when hormonal therapy is discontinued at 5 years, the curves plotting benefit continue to separate for several years afterwards.

Depends: What are you taking it for? If you're taking low dose to suppress aromatization it's not a big deal. If you're taking post-breast cancer therapy then it's more important not to miss a dose. However, Anastrozole has an extremely long half-life so missing one dose is likely not going to have any consequences.

Side effects/options: Discuss the other hormonal therapy options, benefits, and side effects. With ais, address the bone and joint symptoms (arthralgias) and most particularly the effect on bone density. Patients starting on an ai should have a recent or baseline bone densitometry at the start of treatment.

Depends: If you are using this off label for estrogen blockade in the context of testosterone usage; then anywhere form 1-2mg/week works well. See a doc who specializes in hormone replacement therapy. This is beyond the scope of most primary care docs out there. www.blueskymd.com.

Not likely . . .: Check out https://online.Epocrates.Com/noframe/showpage.Do?Method=drugs&monographid=403&activesectionid=10 for info re anastrozole. I could not find any link to thyroid concerns. It might increase testosterone production . .

See below: Anastrozole (marketed under the trade name Arimidex (anastrozole) by astrazeneca) is an aromatase-inhibiting drug approved for treatment of breast cancer after surgery, as well as for metastasis in both pre and post-menopausal women. The severity of breast cancer is increased by estrogen, as sex hormones cause hyperplasia, and differentiation at estrogen receptor sites.
