Casodex
Casodex
- Casodex (bicalutamide) is dispensed in pharmacies and hospitals in Canada and internationally; it is a prescription-only medicine (Rx) and legitimate pharmacies will require a valid prescription for sale.
- Casodex is used in the hormonal treatment of prostate cancer; it is a nonsteroidal anti‑androgen that competitively blocks androgen receptors, reducing the effect of testosterone and dihydrotestosterone on prostate cancer cells.
- Usual adult dosing is 50 mg once daily in combination with an LHRH analogue for metastatic disease; 150 mg once daily is used as monotherapy for certain locally advanced, non‑metastatic cases where licensed—always follow prescriber guidance.
- Casodex is given orally as a film‑coated tablet (commonly 50 mg and 150 mg strengths).
- Pharmacologic effects begin within hours (peak plasma concentrations within a few hours), but meaningful clinical responses (e.g., PSA changes or symptom improvement) typically take weeks to months.
- The drug is taken once daily and provides 24‑hour coverage; bicalutamide has a relatively long elimination half‑life (on the order of days), with steady state reached over several weeks.
- Avoid heavy alcohol use and be cautious with any alcohol consumption, especially if you have liver disease, as alcohol may worsen fatigue and increase risk of liver injury while taking Casodex.
- The most common side effect is hot flashes (other frequent effects include breast tenderness or enlargement/gynecomastia, fatigue, gastrointestinal upset and elevated liver enzymes).
- Would you like to try casodex without a prescription?

Health Canada‑aligned use follows global approvals for prostate adenocarcinoma management.
Typical authorised use is as an anti‑androgen for metastatic prostate cancer in combination with an LHRH analogue at 50 mg once daily.
Off‑Label Patterns In Canadian Healthcare
How Do Clinicians Sometimes Use Bicalutamide Off‑Label?
In certain clinical scenarios and regional protocols, higher‑dose monotherapy (150 mg once daily) is used for locally advanced non‑metastatic disease where practice permits.
Off‑label or less common uses include flare prevention when starting LHRH therapy and short‑term peri‑procedural hormonal manipulation.
| Indication | Typical Dose | Funding Likelihood By Province |
|---|---|---|
| Metastatic Prostate Cancer (Combination) | 50 mg once daily with LHRH analogue | Moderate to High (often covered via cancer agency formularies) |
| Locally Advanced Non‑Metastatic (Selected Monotherapy) | 150 mg once daily (regionally variable) | Variable; may require special authorization |
| Peri‑procedural Use / Flare Prevention | Short course 50 mg | Usually clinic‑arranged; funding varies |
How It Works In The Body
Layman’s Explanation (Canadian Patient‑Friendly Tone)
How Does Casodex Fight Prostate Cancer?
Bicalutamide is an anti‑androgen that blocks testosterone from activating prostate cancer cells.
Think of testosterone as a key and the androgen receptor as the lock; bicalutamide fits the lock so the key cannot turn it.
When combined with an LHRH agonist that lowers testosterone production, the two together reduce the signals that help prostate cancer grow.
Clinical Detail From Health Canada Resources
What Clinical Actions And Monitoring Are Important?
Pharmacologically, bicalutamide is a non‑steroidal androgen receptor antagonist and is classified under ATC L02BB03.
It binds androgen receptors in prostate tissue and inhibits androgen‑driven transcriptional activity.
Health Canada‑aligned product information emphasises baseline and periodic liver function tests because of potential hepatotoxicity.
Drug interactions of note include effects on warfarin and other narrow‑therapeutic‑index medicines, so monitoring is advised.
Onset of pharmacologic effect is reflected in PSA decline; symptomatic benefit may lag behind biochemical changes.
Dosage & Administration
Standard Regimens Per Canadian Guidelines
What Is The Usual Dosing?
Standard regimen for metastatic prostate cancer is bicalutamide 50 mg once daily combined with an LHRH analogue.
Selected locally advanced cases may use 150 mg once daily as monotherapy in regions that allow that approach.
Tablets are taken orally and may be taken with or without food.
Metastatic treatment is typically continued until progression or unacceptable toxicity.
Adjustments By Patient Type (With Canadian Clinical Notes)
Who Needs Dose Changes?
Children: contraindicated and not indicated.
Elderly: no routine adjustment is required; standard doses are used.
Hepatic impairment: caution is advised and moderate to severe impairment generally makes bicalutamide unsuitable.
Renal impairment: no regular adjustment is generally needed.
| Indication | Dose | Monitoring Timeline |
|---|---|---|
| Metastatic Disease (Combo) | 50 mg once daily | LFT baseline, 1–3 months, then periodically; PSA per oncology protocol |
| Locally Advanced (Selected Monotherapy) | 150 mg once daily | LFT baseline and close early monitoring; PSA per protocol |
- Missed Dose: Take when remembered unless close to the next dose; do not double.
- Overdose: Supportive care and urgent medical attention as needed.
Contraindications & Side Effects
Common (Health Canada‑Approved List)
Who Should Not Take Casodex?
Absolute contraindications include women, children, hypersensitivity to bicalutamide or excipients, and severe hepatic impairment.
Common side effects include hot flashes, breast tenderness or gynecomastia, rash, anaemia, weakness, peripheral oedema, pain and gastrointestinal symptoms.
Elevated liver enzymes (ALT/AST) are an important laboratory finding to monitor, especially early in treatment.
Rare But Serious (With Canadian Pharmacovigilance Data)
