Gonadotropin-Releasing Hormone (GnRH) Analogue — Hormone Therapy
Last reviewed June 2026
Who is this for?
Goserelin (commonly known as Zoladex in Nigeria) is a hormone-blocking injection that works by telling your brain to stop producing certain sex hormones like estrogen in women and testosterone in men, which can fuel the growth of some cancers and other conditions.
Binds to GnRH receptors in the anterior pituitary, causing initial stimulation followed by prolonged suppression of gonadotropin (LH and FSH) secretion, thereby reducing testosterone and estrogen production.
Prescription Required
You need a doctor's prescription to buy this drug.
Explore this drug
This is not a drug you take at home by yourself. A doctor or nurse will inject a small implant under the skin of your lower belly. The Zoladex 3.6 mg is given once every 28 days (monthly), and the Zoladex LA 10.8 mg is given once every 12 weeks (about 3 months). You must keep all your appointment dates to get the next dose on time.
If you miss your scheduled injection appointment, contact your doctor or hospital as soon as possible to reschedule. Do not wait until your next planned visit — getting the injection late can reduce how well the treatment works.
Only get this injection from a hospital, clinic, or qualified healthcare provider — never buy or accept it from unregistered sellers. Make sure the packaging is sealed and not expired before the injection is given. Do not stop your treatment schedule without talking to your doctor, even if you feel better, as the condition may come back.
Goserelin may affect how drugs that change heart rhythm work (like some malaria or infection drugs), so tell your doctor about all medicines you are taking. There are no major food interactions, but avoid excessive alcohol as it can worsen mood changes and hot flashes.
Check your specific combination
Is it safe to take Goserelin with your other drugs?
Goserelin is NOT safe during pregnancy or breastfeeding — it can cause serious harm to the unborn baby, and women of childbearing age must use non-hormonal contraception (like condoms) during treatment.
The injection should be stored below 25°C, so it needs to be kept in a cool, dry place away from direct sunlight and heat. In Nigeria's hot weather, hospital pharmacies usually store it in the fridge. Keep out of reach of children.
