The name of your medicine is Synarel which contains an active ingredient called nafarelin acetate.
Synarel belongs to a group of medicines called pituitary hormone analogues which work by decreasing the secretion of sex hormones.
Specifically, Synarel belongs to a class of drugs known as synthetic gonadotrophin-releasing hormones.
Synarel is usually prescribed by your doctor to treat a condition called endometriosis. The lining of the uterus or womb is called the endometrium, and part of it is shed during menstruation (periods). In endometriosis, this lining, or endometrial tissue, is found outside the uterus (e.g. ovaries, intestines or other organs in the pelvis), and like normal endometrial tissue, this can bleed during a menstrual cycle.
Although some women with endometriosis may not experience any symptoms, others may have lower back pain, have painful bowel movements, painful periods, or experience pain during intercourse.
Endometrial tissue is affected by the body's hormones, especially oestrogen, which is made by the ovaries. When oestrogen levels are low, endometrial tissue shrinks or may even disappear, and the symptoms of endometriosis ease. Synarel will temporarily reduce the level of oestrogen in the body, thereby temporarily relieving your endometriosis symptoms.
Synarel can also be prescribed by a specialist for women as part of in-vitro fertilisation (IVF) programmes. Synarel assists in decreasing the amount of oestrogen produced by the ovaries. This provides a more controlled situation for subsequent stimulation of the ovaries to produce eggs.
Your doctor may have prescribed Synarel for another purpose.
Ask your doctor if you have any questions why Synarel has been prescribed for you.
Do not give Synarel to anyone else.
Your doctor has prescribed it specifically for you and your condition.

Tell your doctor if:
Tell your doctor if you are taking any other medicines including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Your doctor will tell you how much Synarel to use each day and how long your treatment should continue. Depending on your condition, the usual dose is as follows:
The usual dose of Synarel is one spray to one nostril in the morning and one spray to the other nostril at night. Your bottle of Synarel contains enough medication to last 30 days.
If your doctor increases your daily dose of Synarel, then your bottle will not last the length of time.
Always ensure that you have sufficient supplies of Synarel Nasal Spray so that your treatment is not interrupted.
The usual dose of Synarel is one spray to each nostril in the morning and one spray to each nostril at night. Your bottle of Synarel contains enough medication to last 15 days.
If your doctor has prescribed the use of Synarel Nasal Spray any differently then you should discuss this with him or her.
Before you use a bottle of Synarel Nasal Spray for the first time you have to prime the spray pump.
CAUTION: Avoid breathing in the spray during priming.
Follow these steps:
1. Remove the safety clip and the clear plastic dust cover from the spray bottle.
2. Put two fingers on the "shoulders" of the spray bottle and put your thumb on the bottom of the bottle.
3. Hold the bottle in an upright position away from you. Apply pressure EVENLY to the "shoulders" and push down QUICKLY AND FIRMLY until a fine spray occurs. Usually the spray will appear after about 5 to 10 pumps.
4. The pump is now primed. Priming only needs to be done once when you start using a new bottle of Synarel Nasal Spray. You will waste medication if you prime the pump before each use and will not have enough medication for the entire treatment period.
IMPORTANT TIPS ABOUT USING SYNAREL NASAL SPRAY
1. Your pump should produce a fine mist, which can only be produced by a quick and firm pumping action. It is normal to see some larger droplets of liquid within the fine mist. However, if your Synarel Nasal Spray comes out of the pump as a thin stream of liquid rather than as a fine mist, it may not be as effective and you should return this spray to your pharmacist.
2. DO NOT TRY TO ENLARGE THE TINY HOLE IN THE SPRAYER. If the hole is enlarged, the pump will deliver an improper dose of Synarel.
3. The pump is made to deliver only a set amount of medication, no matter how hard you squeeze it.
Using Synarel Nasal Spray
1. Gently blow your nose to clear both nostrils before you use Synarel Nasal Spray.
2. Remove the safety clip and clear plastic dust cover from the spray bottle.
3. Clean the tip of pump. Hold the bottle in a horizontal position and rinse the spray tip with warm water, while wiping the tip with your finger or a clean soft cloth.Do not clean the spray tip with a pointed object. This could cause an improper dose of the spray to be delivered. Do not remove the pump from the bottle, as this will release the priming pressure.Wipe the tip dry with a clean soft cloth or tissue.
4. Bend your head forward a little and put the spray tip into one nostril. (The tip should not reach too far into your nose.) Aim the tip toward the BACK and OUTER SIDE of your nose.
5. Close the other nostril with your finger.
6. Applying pressure EVENLY to the "shoulders", QUICKLY AND FIRMLY pump the sprayer ONE TIME, at the same time as you sniff in gently.
7. Remove the sprayer from your nose and tilt your head backwards for a few seconds. This lets the spray spread over the back of your nose.
8. Do not spray into the other nostril unless your doctor has specifically instructed you to do so.
9. Clean the tip of the pump. Hold the bottle in a horizontal position and rinse the spray tip with warm water, while wiping the tip with your finger or a clean soft cloth.Do not clean the spray tip with a pointed object. This could cause an improper dose of the spray to be delivered. Do not remove the pump from the bottle, as this will release the priming pressure.Wipe the tip dry with a clean soft cloth or tissue.Cleaning the spray tip before and after use is important to prevent clogging of the tip.
10. Replace the safety clip and the clear plastic dust cover on the spray bottle.
You should start using Synarel 2 to 4 days after your period begins and continue to use it everyday for 6 months. This is the usual length of treatment for Synarel.
You should start using Synarel on either day 2 or 21 after your period begins and continue to use it strictly as advised by your doctor until told to cease treatment. The length of treatment will depend on the success or failure of in-vitro fertilisation. Treatment should be stopped at least 3 days before embryo implantation.
It is very important that you do not miss a single dose of Synarel.
However, if you do miss a dose, follow the directions below.
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember and then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you miss one or more doses of Synarel, vaginal bleeding (often called breakthrough bleeding) may occur.
If you miss successive doses of Synarel (two or more doses following each other) and have not been using contraceptive measures (as described in the section "While you are using Synarel"), there is a possibility you could be pregnant.
See your doctor immediately to check if you are pregnant.
Below are some tips to help you remember to use Synarel regularly.
Immediately telephone your doctor, or the Poisons Information Centre (telephone 131 126), or go to accident and emergency at your nearest hospital, if you think you or anyone else may have taken too much Synarel. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
At present, there is very limited experience with cases of Synarel overdosage when used as a spray.
If Synarel is accidently ingested, enzymes in the stomach and bowels will inactivate the medication.
Make sure that all doctors, dentists and pharmacists who are treating you know that you are using Synarel.
Tell the hospital doctor that you are using Synarel if you need to have an operation, or go to hospital in an emergency.
If you are about to be started on any new medicine, tell your doctor or dentist and your pharmacist that you are using Synarel.
If you become pregnant while using Synarel, see your doctor immediately.
While using Synarel it is important to use a non-hormonal method of contraception such as a diaphragm with contraceptive jelly, an IUD or condoms.
If you are on an IVF programme make sure that you keep all appointments so that your condition can be monitored.
Speak to your doctor about how Synarel may affect your bones.
When you use Synarel, your oestrogen levels will be low. Low oestrogen levels can result in a loss of mineral from bone. During the six month treatment course of Synarel you will lose a small amount of mineral from your bones. In most women a single six month treatment course of Synarel should not be a concern. However, you should discuss the effect of Synarel on bone with your doctor and particularly how this may affect you.
You should also be aware that repeat treatments close together (that is, more than one treatment period of 6 months) are not recommended. However, if your doctor considers that a second course of treatment is necessary he or she will ask you to undergo bone density studies prior to a repeat course of Synarel.
Do not take birth control pills (oral contraceptives) while you are using Synarel. Use another method of contraception such as a diaphragm with contraceptive jelly, an IUD or condoms.
Do not use the spray bottle beyond 30 days if you are using 2 sprays per day, or beyond 15 days if you are using 4 sprays per day.
At the end of the recommended 15 or 30 days, a small amount of liquid will be left in the bottle.
Do not try to use the leftover amount because you may get too low a dose of medication, which could interfere with the effectiveness of your treatment. Dispose of the bottle and do not use again.
Do not use Synarel Nasal Spray past the expiry date shown on the label.
If you use the spray after the expiry date has passed, it may not work as well.
For the first two months after you start using Synarel, you may experience some irregular vaginal spotting or bleeding. The amount of bleeding and the time this bleeding continues for may vary. This bleeding will usually stop by itself. After the first two months of Synarel treatment, you can expect a decrease in menstrual flow, and your periods may stop altogether. However, if you miss one or more doses of Synarel, you may continue to experience vaginal bleeding.
See your doctor if you continue to have normal periods after two months of using Synarel.
If you suffer from hayfever or have a cold (which results in a runny or blocked nose) during Synarel treatment, you should see your doctor for a nasal decongestant. This decongestant should be used at least 30 minutes after using Synarel Nasal Spray so that the absorption of Synarel is not affected.
Synarel is not expected to affect driving or operating of machinery.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Synarel.
Synarel helps most women with endometriosis and/or in an in vitro fertilisation programme but it may have unwanted side effects in some women.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Due to the initial high levels of oestrogen when you start Synarel therapy, you may experience oestrogen-sensitive migraine or epilepsy. These will clear provided you continue to use your Synarel as directed
Continuous treatment may induce a menopausal state.
Tell your doctor if you notice any of the following and they worry you:
Tell your doctor immediately if you notice any of the following:
This is not a complete list of all possible side effects. Others may occur in some people and there may be some side effects not yet known.
Tell your doctor if you notice anything else that is making you feel unwell, even if it is not on this list.

Do not put your spray in the freezer or refrigerator.
If you have accidentally stored Synarel in the refrigerator, take it out and leave it at room temperature for at least 1 hour before using it.
If your doctor tells you to stop taking Synarel ask your pharmacist what to do with any nasal spray that is left over.
