Fosfestrol
About Fosfestrol
Fosfestrol is an oral prescription medication used as a palliative treatment for advanced, hormone-sensitive prostate cancer. It is prescribed to help manage symptoms and slow the spread of cancer when other therapies may not be suitable. Targeting hormone-dependent cells helps control the progression of the disease.
To get the most benefit, you must take Fosfestrol consistently at the same time every day as directed by your doctor. You can take this tablet with or without food, though taking it with a meal may help prevent mild stomach upset. Incorporating a balanced, heart-healthy diet and staying active can also support your overall well-being during treatment.
While taking this medication, you may experience common side effects such as mild nausea, fluid retention, or breast tenderness. Most of these are manageable, but you must contact your doctor immediately if you experience severe symptoms like sudden chest pain, shortness of breath, or severe leg swelling.
Before starting treatment, tell your doctor if you have a history of heart disease, stroke, or circulation problems. Do not take this if you have active blood clots, severe liver damage, or if you have a known allergy to any of its ingredients.
This medication can interact with alcohol, which may increase the strain on your liver, and smoking, which significantly raises your risk of dangerous blood clots. While this drug is primarily for male patients, it must never be taken by pregnant or breastfeeding individuals due to severe developmental risks.

FAQs
Fosfestrol is used to treat prostate cancer in an adult male.
Fosfestrol contains Fosfestrol, an inactive synthetic oestrogen (sex hormone) that gets converted to active oestrogen in the body. Prostate cancer cells require androgens (male sex hormones) such as testosterone to grow rapidly. Oestrogen lowers the blood levels of androgens and prevents its effects at the tumour site. Thereby, Fosfestrol prevents the growth of prostate cancer cells and eventually shrinks the prostate tumour.
Yes, Fosfestrol relieves difficulty in urination and makes it easier to urinate by shrinking the prostate tumour. This reduces pressure on the urinary bladder, thereby preventing pain and intense urge to urinate.
Fosfestrol should be used with caution in diabetic patients as it may increase the risk of high blood sugar levels. Therefore, it is advised to regularly monitor blood sugar levels while taking Fosfestrol and inform your doctor if you have diabetes before taking Fosfestrol.
