Drug Description


Nolvadex is a well-established Selective Estrogen Receptor Modulator (SERM) with potent therapeutic effects that have earned it widespread popularity. Often regarded as an anti-estrogen, this compound exerts antagonist activity in some tissues while exhibiting agonist activity in others.  

Despite being one of the earliest SERMs developed and still in common use for medicinal purposes, Nolvadex is distinct from anabolic steroids. 

Tamoxifen is a medication prescribed for the treatment of breast cancer and prevention of breast cancer in patients deemed high-risk. Its mechanism of action involves impeding the growth of breast cancer cells by interfering with the effects of estrogen on breast tissue.  

This drug has shown efficacy in blocking the progression of breast cancer and reducing the likelihood of its recurrence. 

Uses and Dosage 

Before commencing the use of tamoxifen, carefully read the Medication Guide provided by the pharmacist. Consult with their physician or pharmacist if they have any questions or concerns. 

Tamoxifen is typically taken by mouth, with or without food, once or twice daily for a period of 5 years as directed by the physician. Daily doses greater than 20 milligrams are generally divided into two halves and administered in the morning and evening, or as directed by the doctor.  

The prescribed dosage of tamoxifen is dependent on the patient’s medical condition and response to treatment. To prevent the return of cancer, treatment duration may last between 5 to 10 years, varying based on the patient’s response to the medication. 

Regular use of tamoxifen is critical for optimum therapeutic outcomes. Patients are encouraged to take the medication at the same time(s) every day to ensure consistent administration. 

Patients with breast cancer that has metastasized to other parts of the body may experience an initial increase in bone/cancer pain and/or disease flare-up upon commencing treatment with tamoxifen. These symptoms may indicate a positive response to the medication, but patients must notify their physician immediately of any such symptoms, which typically resolve quickly. 

Side Effects 

In the event of any persistent or distressing side effects, promptly seek medical attention or consult with your healthcare provider. Common side effects of tamoxifen treatment may include: 

  • Hot flashes 
  • Nausea or vomiting 
  • Fluctuations in weight 
  • Fatigue, dizziness, or general weakness 
  • Bone, back, joint, or muscle pain 
  • Diarrhea or constipation 
  • Sleep disturbances 
  • Feelings of anxiety or nervousness 


Prior to initiating tamoxifen therapy, disclose any known allergies to the medication or its inactive ingredients to your healthcare provider or pharmacist. Provide your full medical history, particularly if you have a history of blood clots, diabetes, high blood pressure, cataracts, liver disease, or mobility limitations. 

If you plan to undergo surgery, including breast reconstruction, inform your doctor or dentist of all medications and supplements you are taking. 

Tamoxifen may pose a risk to a developing fetus and should not be taken during pregnancy. Women using this medication should utilize reliable, non-hormonal methods of birth control during treatment and for two months after discontinuation, while men using tamoxifen should use reliable forms of birth control during treatment and for six months following discontinuation. Speak with your doctor immediately if you or your partner become pregnant.
