⚠️ Specialist-supervised cancer therapy — this medication is started, monitored, and stopped by an oncologist or haematologist. Dosing depends on tumour type, stage, body surface area, organ function, and concomitant therapy. Self-treatment is not appropriate; the information below is educational and supports informed conversations with your specialist.
AIs are NOT effective in pre-menopausal women — without ovarian suppression, ovaries override AI inhibition. Pre-menopausal HR+ breast cancer requires tamoxifen ± ovarian suppression (LHRH agonist) or AI WITH ovarian suppression as a specialist-supervised regimen.
AIs accelerate bone density loss and fracture risk. Baseline DEXA is recommended; consider bisphosphonate (zoledronic acid, ibandronate) or denosumab in osteopenia/osteoporosis. AIs may modestly raise lipid levels and cardiovascular events vs tamoxifen. Monitor lipids and cardiovascular risk factors annually.
Vanlige spørsmål
AI vs tamoxifen — which is better?
In post-menopausal HR+ breast cancer, AIs (anastrozole, letrozole, exemestane) give modestly higher disease-free survival than tamoxifen (ATAC, BIG 1-98, MA.17). AIs are preferred adjuvant in most post-menopausal women; tamoxifen remains preferred in pre-menopausal disease and in patients with severe AI side effects.
How long is treatment?
Adjuvant therapy is typically 5 years; some women benefit from extended adjuvant (5-10 years total) based on ATLAS/MA.17 data. Specialist decides extended therapy based on recurrence risk.
Common side effects?
Hot flushes, joint and muscle pain (arthralgia/myalgia — affects 30-50%, often improves with continued therapy), fatigue, vaginal dryness, mood changes, accelerated bone loss.
Joint pain — is it serious?
AI-related arthralgia is the most common reason for non-adherence. Often improves over 3-6 months; symptomatic relief with NSAIDs, exercise, occasionally switching between AIs (anastrozole ↔ letrozole ↔ exemestane). Vitamin D + calcium adequacy helps.
What if I’m pre-menopausal?
AIs alone do not work — ovaries override. Discuss tamoxifen, or AI + ovarian suppression, with your specialist.
Knochetetthet?
Mandatory baseline DEXA. Repeat every 1-2 years. Add a bisphosphonate or denosumab if osteopenia or osteoporosis develops, or in high baseline-risk patients prophylactically.
Side effects vs exemestane?
Anastrozole and letrozole are non-steroidal AIs (reversible). Exemestane is a steroidal AI (irreversible inactivator). Side-effect profiles broadly similar; some women prefer one over another. Switching is reasonable for tolerability.
Vaginal dryness?
Common. Topical vaginal moisturisers and water-based lubricants help. Topical oestrogen (very low dose, vaginal) is generally avoided in HR+ breast cancer; if symptoms severe, discuss with oncologist — vaginal DHEA, ospemifene, or specialist menopause review may be options.
Legemiddelinteraksjoner?
Few major. CYP-modulators have minimal effect on AIs. Tamoxifen and AIs should NOT be combined (no benefit). Always disclose all medications.
Hva om jeg glemmer en dose?
Take when you remember if same day; otherwise skip. Do not double up. Consistent daily dosing maximises effect.
