Cyclogest
In brief
- Cyclogest (micronised progesterone capsules) can be purchased in our pharmacy without a prescription, with delivery available across the United Kingdom.
- Prometrium (UK equivalent: Utrogestan) contains micronised progesterone, the natural hormone, in oral capsules of 100 mg and 200 mg.
- It is used for endometrial protection alongside oestrogen in hormone replacement therapy and for secondary amenorrhoea; fertility clinics also use progesterone for luteal support.
- Dosing depends on the indication, for example 200 mg at bedtime for 12 days of a 28-day cycle with oestrogen, or 400 mg at bedtime for 10 days in secondary amenorrhoea.
- It is taken by mouth as a capsule, swallowed whole with water, preferably at bedtime because it can cause drowsiness.
- Drowsiness and dizziness can appear within a few hours of a dose, which is why evening dosing is advised.
- Take it once daily at the same time each evening and do not double a missed dose.
- Limit alcohol while using this medicine, as it can add to drowsiness and dizziness.
- Common side effects include headache, breast tenderness, abdominal cramps, dizziness, fatigue and mood changes.

Morning vs evening dosing
Prometrium can be taken either in the morning or evening. However, healthcare professionals commonly recommend the evening slot due to drowsiness being a potential side effect.
- Taking it at night can help ease any fatigue that may occur.
Maintaining a consistent dosing schedule is imperative to ensure optimal effectiveness. Variations in timing can impact how well the body responds to the medication, so it's best to stick to a routine.
Taking with or without meals (UK diet habits)
Patients have the flexibility to take Prometrium with or without food. Taking it with a meal may reduce gastrointestinal discomfort, a concern for many patients.
Given frequent dietary habits in the UK, which often include rich and heavy meals, timing Prometrium administration after a light meal can be beneficial.
- This approach may help to minimise symptoms such as nausea or other digestive side effects.
Furthermore, keeping a simple food diary can help patients identify any dietary patterns that might influence how Prometrium works for them. Such documentation may offer insights into potential triggers for side effects and improve the overall experience with this treatment.
In summary, whether it's the morning or evening, consistency is key. Adjusting the timing in conjunction with meal intake may provide extra comfort and better outcomes for those patients on Prometrium. Understanding how to best utilise this medication is paramount in achieving the desired results whether during IVF or for other hormonal balancing needs.
Ingredients overview
Prometrium features micronised progesterone as its active ingredient, a hormone that the body naturally produces. Alongside progesterone, the formulation includes excipients like peanut oil, which enhances the delivery and absorption of the medication. However, patients with peanut allergies should consult their healthcare provider about alternative medications before starting treatment.
Mechanism basics explained simply
The main function of progesterone is to prepare the uterus for the implantation of a fertilised egg and to sustain early pregnancy stages. Prometrium helps support the luteal phase by stabilising the endometrium, which is crucial for those trying to conceive. It plays a pivotal role in regulating hormonal balance and preventing complications, such as thickening of the endometrium during hormone replacement therapy.
Understanding how Prometrium works provides valuable insight for those undergoing treatment. This awareness allows patients to appreciate its significance in aiding conception and maintaining a healthy pregnancy, further cultivating confidence in their treatment choice.
Main indications
When it comes to the use of Prometrium, many people wonder about its main indications and effectiveness in various treatments. Understanding these can help patients navigate their options better.
Approved uses (MHRA listing)
Prometrium is primarily indicated for use in aiding fertility treatments, especially during in-vitro fertilisation (IVF) attempts. Many women rely on this medication to enhance their chances of conception. In addition to its role in fertility, Prometrium is also prescribed for:
- Treating secondary amenorrhoea, a condition where a woman misses her period for an extended time after having had regular menstrual cycles.
- Protecting the endometrium in women undergoing hormone replacement therapy, particularly as part of postmenopausal treatment regimens.
Off-label uses in UK clinics
Interestingly, some clinicians may prescribe Prometrium off-label for conditions like luteal phase defects or to prevent recurrent miscarriage. This approach often involves closely monitoring the patient and engaging in meaningful conversations about treatment expectations. Such off-label uses highlight the necessity for open communication between healthcare providers and patients regarding Prometrium’s effectiveness and potential side effects.
Interaction warnings
Interactions can be a concern for many during their treatment plan. Knowing what to avoid while taking Prometrium is crucial for patient safety.
Drug conflicts (MHRA Yellow Card reports)
Interaction with other drugs requires careful consideration. Particularly, medications that affect liver enzymes can significantly impact the metabolism of Prometrium. Examples include certain anticonvulsants and antifungal medications, which may reduce its effectiveness. Patients are encouraged to discuss their complete medication lists with healthcare providers to assess potential risks and ensure safe interactions.
