In some cases, the dosage may be adjusted based on various factors, including:

  1. Patient’s age
  2. Weight and overall health
  3. Other concurrent medications
  4. Side effects experienced

Potential Side Effects

While aromatase inhibitors are effective for treating breast cancer, they may cause side effects such as:

  • Hot flashes
