Generic Casodex (Bicalutamide) – Med Supply Drive

A drug called Casodex is used to treat the symptoms that are characteristic of prostate cancer. It may be administered alone or in combination with other drugs. When used in conjunction with other medications or surgical procedures, Casodex has shown to be a successful treatment for advanced prostate cancers that have metastasized.

When other medication therapies, surgery, or radiation therapy cannot be performed, locally advanced prostate cancers without metastases can be treated with Casodex using higher doses, or as maintenance therapy following surgical removal or radiation.

Casodex is a member of a group of medications known as moderate-strength antineoplastic, antiandrogen, and CYP3A4 inhibitors. Non-steroidal antiandrogen Casodex has no additional impact on the endocrine system. The medication inhibits androgenic stimuli by binding to androgen receptors without triggering gene expression. This inhibition causes the prostate tumor to recede.

In other words, it contains bicalutamide, which is the active component. It prevents androgens’ (male hormones) unfavorable influence on prostate growth. There are certain instances in which individuals experience withdrawal symptoms after they stop taking medicine.

Casodex is only available with a prescription and must be used under the constant supervision of a doctor.

Cost of Generic and Brand

The price for Casodex in the US varies between $200 and $300 for thirty 50mg tablets for a generic version of this medication. The brand Casodex can be around $1000 but can go much higher, up to $4,000. In Canada, the prices are about on the same level, but there is more chance to find a cheaper offer.

How to use?

The usual dose is one coated tablet per day that can have 50 mg of the active substance or three times this amount.  You should always take the tablets at approximately the same time, such as at breakfast. It doesn’t matter if you swallow the tablets before, during, or after a meal.

If you forget to take a tablet for one day, you should not take it later, but take the next tablet at the usual time of the next day. If you accidentally took double or more of the prescribed dose, you need to let the medical specialist know about it without wasting time. You should never change the prescribed dosage on your own. If you think the medicine is too weak or too strong, have your doctor reevaluate the treatment plan.

Effectiveness and safety of Casodex

In a combined evaluation of three double-blind, placebo-controlled studies including more than 8,000 participants, the treatment of localized or locally progressed prostate cancers without metastases with casodex at a dosage of 150 mg was investigated.

Casodex was administered as supportive medication for radiation or radical prostatectomy as well as emergency hormonal therapy. Almost 10 years later, there was a noticeable disease progression in 36.6% of men using Casodex and 38.17% of those taking a placebo, respectively.

A reduction in the risk of health issue progression was recorded in a significant number of individuals, but it was most noticeable in individuals at high risk. Accordingly, the doctor may decide that the best way to go for low risk individuals, in particular with the use of the drug after radical prostatectomy, may be to delay hormones until signs that the sickness is worsening appear.

In a clinical study, the mean concentration of (R)-bicalutamide in the semen of men treated with Casodex at a dosage of 150 mg was 4.9 µg/ml. The amount of bicalutamide potentially ingested by a female partner during intercourse is low and may be around 0.3 µg/mL, which did not lead to an exposure of offspring in laboratory animals.


There is not enough research to determine if this drug is safe for children. As a result, it is not typically prescribed to people of this age.

Casodex shouldn’t be given to women, especially if they are expecting a baby or breastfeeding. Men and/or their partners are encouraged to adhere to effective methods of contraception during the Casodex treatment course and three months after it.

Increased sensitivity to any of its chemical elements means a healthcare provider might need to turn to alternatives.

Despite the fact that the impact of bicalutamide on the structure of sperm has not been studied, Casodex users have not reported seeing such alterations. Impaired fertility has been seen in animal studies. It was, though, reversible. It should be assumed that males may have infertility or experience periods of insufficient reproductive function.

You must use a reliable form of birth control while taking the medication and for three months after stopping it. This goes for your partner as well. If you are worried, your doctor may provide you with further information on this topic.
