Dosing & Uses

AdultPediatric

Dosing Form & Strengths

tablet

60mg

Osteoporosis in Post-menopausal Women

60 mg PO qDay

Breast Cancer

Prevention; risk reduction of invasive breast cancer in postmenopausal women at high risk for invasive breast cancer

60 mg PO qDay for 5 years

Dosing Modifications

Moderate to severe renal impairment: Caution; safety and efficacy not established

Mild hepatic impairment: Safety and efficacy not established

Dosing Considerations

Calcium and vitamin D supplementation

Postmenopausal patients should take supplemental calcium and vitamin D if dietary intake is not adequate
Postmenopausal women require an average of 1500 mg/day of elemental calcium
Total daily intake of calcium above 1500 mg has not demonstrated additional bone benefits
Daily intake above 2000 mg has been associated with increased risk of adverse effects, including hypercalcemia and kidney stones
The recommended intake of vitamin D is 400-800 IU daily

Breast cancer risk

High risk of breast cancer is defined as at least 1 breast biopsy showing lobular carcinoma in situ (LCIS) or atypical hyperplasia, 1 or more first-degree relatives with breast cancer, or a 5-year predicted risk of breast cancer >1.66% (based on the modified Gail model)

Limitations of use for breast cancer risk reduction

There are no data available regarding the effect on invasive breast cancer incidence in women with inherited mutations (BRCA1, BRCA2), so specific recommendations on the effectiveness of raloxifene cannot be made
Not indicated for the treatment of invasive breast cancer or reduction of the risk of recurrence
Not indicated for reduction in the risk of noninvasive breast cancer

Not recommended

Serious - Use Alternative

Significant - Monitor Closely

All Interactions Sort By:

Contraindicated (1)

ospemifene
ospemifene, raloxifene. Either increases effects of the other by pharmacodynamic synergism. Contraindicated.

Serious - Use Alternative (0)

Monitor Closely (4)

apalutamide
apalutamide will decrease the level or effect of raloxifene by increasing elimination. Use Caution/Monitor. Apalutamide induces UGT and may decrease systemic exposure of drugs that are UGT substrates.
cholestyramine
cholestyramine decreases levels of raloxifene by inhibition of GI absorption. Applies only to oral form of both agents. Use Caution/Monitor.
famciclovir
raloxifene decreases levels of famciclovir by aldehyde dehydrogenase inhibition. Use Caution/Monitor. The conversion of 6-deoxy penciclovir to penciclovir is catalyzed by aldehyde oxidase. Interactions with other drugs metabolized by this enzyme and/or inhibiting this enzyme could potentially occur. Raloxifene, a potent aldehyde oxidase inhibitor in vitro, could decrease the formation of penciclovir.
levothyroxine
raloxifene decreases levels of levothyroxine by inhibition of GI absorption. Applies only to oral form of both agents. Use Caution/Monitor.

Supplemental calcium and vitamin D recommended

Therapy should not be used for primary or secondary prevention of cardiovascular disease

Triglyceride levels may increase in women with history of triglyceride elevation in response to oral estrogens; monitor serum triglycerides

Concomitant use of estrogens not recommended; taper off estrogen treatment, then wait month before starting raloxifene

Examine unexplained uterine bleeding

Use with caution in renal or hepatic impairment

Premenopausal use not recommended

Pregnancy & Lactation

Pregnancy Category: X

Lactation: Excretion in milk unknown; contraindicated

Pregnancy Categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

Also, women who have had a heart attack or are at risk for a heart attack may rarely have an increased risk of dying from a stroke while taking raloxifene.

In other parts of the body (uterus and breasts), raloxifene acts like an estrogen blocker. It does not relieve menopause symptoms such as hot flashes. Raloxifene belongs to a class of drugs known as selective estrogen receptor modulators-SERMs.This medication should not be used before menopause.It should not be used to prevent heart disease.
