• your cancer has spread to the spine (when being treated for prostate cancer)
• you have any other medical conditions not already discussed with your doctor
• you take any medicines for any other condition.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Although not expected to be applicable, make sure your doctor is aware you are pregnant or are breastfeeding.

Hormonal Flare

Symptoms may increase at the beginning of treatment. This is applicable to patients being treated for prostate cancer (also known as tumour flare) and precocious puberty. Refer to Section 6 Are there any side effects? for advice on symptoms of hormonal flare and what to do if you experience any of them.

Allergic Skin Reactions (in children and men)

Very rare, severe allergic skin reactions that include a rash with blisters and peeling called Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis have been reported. If you develop these symptoms after receiving Lucrin, contact your healthcare provider right away or get emergency medical help.

Pituitary apoplexy (in children)

The pituitary gland is a small gland in your brain that plays a major role in regulating body functions and general wellbeing. Pituitary apoplexy is a condition where blood flow is restricted into the pituitary gland. If your child experiences symptoms including sudden headache, vomiting, changes to vision, unconsciousness, then urgent medical attention is required.

Pseudotumor cerebri (PTC)/idiopathic intracranial hypertension (in children)

A condition characterised by increased pressure inside the head (intracranial pressure) for no obvious reasons has been reported in children receiving this medicine.

Monitor/watch your child for signs and symptoms of PTC including headache, vision issues such as blurred vision, double vision, loss of vision, pain behind the eye or pain with eye movement, ringing in the ears, dizziness, and nausea. Contact your doctor immediately and take your child to an ophthalmologist (an eye specialist) to find out if there is papilloedema (pressure in or around the brain which causes the part of the optic nerve inside the eye to swell). If papilloedema is present, this means your child has PTC and immediate treatment is necessary.

Metabolic syndrome (in men)

If you are male and have a history of high blood sugar, diabetes, high cholesterol, and/or fatty liver, your doctor should monitor you closely for metabolic syndrome/changes.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Lucrin and affect how it works, while Lucrin may affect how other medicines work.
