Progestérone

About progesterone

Progesterone is a naturally occurring female sex hormone which is essential for the function of the female reproductive system. It is produced in the ovaries during the second half of the menstrual cycle, and also by the placenta during pregnancy. The amount of progesterone a woman produces declines during the menopause.

You will have been prescribed progesterone to supplement your naturally produced progesterone for a reason which your doctor will have explained to you. It works by adjusting the balance of your body's own hormones.

Progesterone is available in a number of formulations that are the subject of this leaflet (gel, injection, capsules, and pessaries). Each formulation is prescribed for a different gynaecological reason.

Progesterone may also be included as an ingredient in a number of combination products used for a variety of medical reasons. These products are not covered by this leaflet and you should read the printed information provided by your doctor and the manufacturer.

Before taking progesterone

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking progesterone, it is important that your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• If you have migraines, asthma, epilepsy or high blood pressure.

• If you are having any vaginal bleeding other than your normal monthly period.

• If you have ever had a blood clot in your legs or lungs.

• Si vous avez une maladie cardiaque.

• If you have had any problems with the way your liver or kidneys work.

• If you have ever had depression.

• Si vous avez trop de sucre dans le sang (diabète sucré).

• Si vous avez un cancer.

• If during a pregnancy you had problems such as severe itching, yellowing of your skin or of the whites of your eyes (jaundice), or a skin condition called pemphigoid gestationis.

• Si vous avez un trouble sanguin héréditaire rare appelé porphyrie.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Si vous prenez ou utilisez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et complémentaires.

How to take progesterone

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about the brand of progesterone you have been given. It will also provide a full list of side-effects which you may experience.

• Follow carefully the instructions your doctor has given you. Progesterone is usually only used on a number of specified days during a monthly cycle. This may range from 4 to 25 days of a month depending on the reason it has been prescribed for you. If you are unsure about what to do, check again with your doctor.

If you have been prescribed:

• Utrogestan® capsules as HRT: these should be taken at bedtime, on an empty stomach. This means that you should not take them with or soon after eating food. Just take them on the days of the month your doctor has told you to. You will also be prescribed an oestrogen-containing HRT medicine to take throughout the month.

• Utrogestan vaginal® capsules for fertility treatment: use the applicator and follow the manufacturer's instructions for inserting the capsule high into the vagina. Do not take the capsule by mouth, although if you do swallow it accidentally, it will not harm you. The capsules are usually prescribed during the first three months of pregnancy only.

• Lutigest® vaginal tablets for fertility treatment: put one tablet into the end of the applicator and use it to insert the tablet into the vagina following the manufacturer's instructions. Push the plunger to release the tablet. The usual dose is one tablet inserted three times daily starting on the day of egg retrieval. You will need to continue using Lutigest® for 30 days if pregnancy is confirmed. Follow the instructions of your doctor.

• Crinone® vaginal gel for fertility treatment: use one 'applicatorful' daily into the vagina. Just use it on the days of the month your doctor has told you to.

• Cyclogest® pessaries for menstrual problems: use twice daily on the days of the month your doctor has told you to. Pessaries are generally designed to be inserted into the vagina, but Cyclogest® pessaries are also suitable to be inserted into the back passage, as a suppository. If you are unsure which is the correct way for you to use them, check again with your doctor.

• Lubion® injection for fertility treatment: make sure you know how to use this injection. If you are unsure which days to use it, or how much to use, check again with your doctor or clinic.

Tirer le meilleur parti de votre traitement

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Also, remember to keep any routine appointments for breast screening and cervical smear tests.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are on progesterone.

• If you have diabetes you may need to check your blood glucose more frequently, as progesterone can affect the levels of sugar in your blood. Your doctor will advise you about this.

• It is best to avoid smoking and drinking too much alcohol while on progesterone. If you are a smoker and you would like advice on how to quit, speak with your doctor or pharmacist.

• If you buy any medicines, check with a pharmacist that they are suitable to take with progesterone. This is because some herbal preparations (such as St John's wort) can interfere with the way it works.

Can progesterone cause problems?

Along with their useful effects, all medicines can cause unwanted side-effects although not everyone experiences them. The table below lists some of the most common ones associated with progesterone. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve over the first few days of taking or using a new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.

Si vous ressentez d'autres symptômes que vous pensez être dus à ce médicament, parlez-en à votre médecin ou à votre pharmacien.
