When treating these conditions, women typically receive a Goserelin injection once a month. Your doctor might also use this medicine for other health needs not listed here. If you have any questions, always ask your doctor or pharmacist. You might also hear this medicine called by its brand names, such as Zoladex or Zoladex 3-Month.
