5 Conservation of Cyclogest
Cyclogest contains progesterone, which is a natural female sex hormone produced in the body.
Cyclogest is for women who need extra progesterone while undergoing treatment as part of an Assisted Reproduction Technique (ART) procedure.
Progesterone acts on the lining of the uterus and helps to maintain pregnancy when undergoing fertility treatment.
Do not use Cyclogest:
Warnings and precautions
Be particularly careful and consult your doctor directly if you experience any of these symptoms during treatment or even a few days after the last administration:
Before treatment with Cyclogest, consult your doctor if you have or have had any of the following health problems:
Children and adolescents
There is no specific use for Cyclogest in children.
Using Cyclogest with other medications
Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.
This is especially important if you are taking carbamazepine (e.g., to prevent epileptic seizures, to treat certain types of pain or mood disorders), rifampicin (to treat infections), or phenytoin (e.g., to prevent epileptic seizures or treat certain types of pain), as they may reduce the effectiveness of progesterone.
The use of other vaginal products at the same time as Cyclogest is not recommended, as it is not known whether it affects treatment.
Pregnancy and breastfeeding
Cyclogest may be used during the first trimester of pregnancy for women who need extra progesterone while undergoing treatment as part of an Assisted Reproduction Technique (ART) procedure.
The risk of congenital anomalies (conditions present at birth), including abnormalities in the genitals of boys and girls, from exposure to exogenous progesterone during pregnancy has not been fully established.
This medication should not be used during breastfeeding.
Driving and using machines
Cyclogest has a low to moderate influence on the ability to drive or use machines. It may cause dizziness; therefore, caution is recommended for drivers and machine users.
Follow your doctor's instructions for administering this medication exactly. If in doubt, consult your doctor again.
The recommended dose is 400 mg twice a day by vaginal insertion. Start using Cyclogest on the day of egg retrieval. If pregnancy is confirmed, Cyclogest administration should be continued until 38 days of treatment have been completed from the start.
How to insert Cyclogest
Always wash your hands before and after inserting the pessary.
To insert it into the vagina, place the pessary between the vaginal lips and push it upwards and backwards. You may find it easier if you are lying down or squatting.
If you use more Cyclogest than you should
If you (or someone else) have accidentally swallowed a pessary or used too many, contact the emergency department of your nearest hospital or consult your doctor immediately for advice.
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount used or ingested.
If you forget to use Cyclogest
If you forget to insert a pessary, do so as soon as you remember, unless it is almost time for your next dose.
Never use two doses together. Remember to use the remaining doses at the correct time.
If you stop using Cyclogest
Consult your doctor or pharmacist if you intend to stop or have stopped using Cyclogest. Abruptly stopping progesterone administration may cause anxiety, irritability, and increased sensitivity to seizures.
If you have any other doubts about using this medication, ask your doctor or pharmacist.
