Hormone Therapy Decision Guide
Your Hormone Therapy Preferences
What you need to know
- Cycrin is a brand of medroxyprogesterone acetate (MPA) used mainly for hormone replacement therapy (HRT) and menstrual disorders.
- Common alternatives include Provera, Depo‑Provera, Prempro and several newer progesterone‑only pills.
- Key decision factors are route of administration, dosing frequency, side‑effect profile and cost on the UK NHS.
- For most women, oral tablets are easier to manage, while injections may suit those who need strict adherence.
- Understanding the risk‑benefit balance helps you choose the right option for menopause or contraception.
When doctors prescribe Cycrin-a branded form of medroxyprogesterone acetate (MPA)-it acts as a synthetic progesterone for hormone replacement and other uses. While Cycrin has been on the market for decades, many patients wonder whether newer or cheaper options might work better for them. This guide walks you through the most relevant alternatives, compares them side‑by‑side, and gives practical tips on picking the right one.
How Cycrin works
Medroxyprogesterone acetate is a progestin that mimics the natural hormone progesterone. It binds to progesterone receptors in the uterus, breast and brain, helping to regulate the menstrual cycle, protect the endometrium when estrogen is given, and suppress ovulation in contraceptive doses. In the UK, Cycrin is usually prescribed as 10mg tablets taken for 10‑14 days each month, often together with an estrogen tablet as part of HRT.
Common alternatives
The market offers several other progestins that serve the same therapeutic goals. Below are the most widely used options, each introduced with microdata for clarity.
Provera is the generic oral formulation of medroxyprogesterone acetate, identical in strength to Cycrin (10mg) but sold under a different name. It is available on the NHS for the same indications.
Depo‑Provera delivers 150mg of medroxyprogesterone acetate via a 3‑month intramuscular injection. This long‑acting form is popular for contraceptive use and for women who have trouble remembering daily pills.
Prempro combines conjugated estrogen with medroxyprogesterone acetate in a single daily pill. It is marketed in the US but has limited availability in the UK; similar combos are offered as estradiol/MPA packs.
Norigynon contains norethisterone, a different synthetic progestin. It is often used for similar HRT regimes but has a slightly higher androgenic activity, which can affect mood and acne.
Naturogest is a micronized progesterone derived from plant sources. Unlike MPA, it is bioidentical, meaning it shares the exact chemical structure of the body’s own progesterone.
Decision criteria you should weigh
Choosing the right medication isn’t just about brand names. Here are the five criteria most patients consider:
- Route of administration: oral tablets vs. injection vs. transdermal.
- Dosing frequency: daily, monthly, or every three months.
- Side‑effect profile: weight gain, mood swings, breast tenderness, or bone density effects.
- Cost and NHS coverage: some brands are fully reimbursed, others require private purchase.
- Specific indication: menopause symptom relief, contraceptive need, or treatment of endometrial hyperplasia.
Side‑effect snapshot
All progestins share a core set of possible adverse events, but the intensity can differ.
| Medication | Weight gain | Mood changes | Breast tenderness | Bone density impact |
|---|---|---|---|---|
| Cycrin | Low‑moderate | Possible, especially at higher doses | Common during first 3 months | Neutral to slightly protective |
| Provera | Similar to Cycrin | Similar | Similar | Neutral |
| Depo‑Provera | Higher (due to steady serum levels) | Higher risk of mood swings | Less frequent, but can be intense after injection | Positive - helps preserve bone density |
| Prempro | Low | Variable | Low to moderate | Neutral |
| Naturogest | Very low | Often better tolerated | Minimal | Positive - supports bone health |
Cost and NHS availability (2025)
Prices fluctuate, but here’s a snapshot for the UK:
| Medication | Typical dose | Monthly cost (NHS) | Private price (≈) |
|---|---|---|---|
| Cycrin | 10mg × 10‑14 days | £0 (fully subsidised) | £15‑£20 |
| Provera | 10mg × 10‑14 days | £0 (generics covered) | £10‑£15 |
| Depo‑Provera | 150mg injection q‑3months | £0 (if prescribed for contraception) | £30‑£35 per injection |
| Prempro | 1tablet daily | £5‑£8 (partial) | £40‑£45 |
| Naturogest | 200mg micronized | £2‑£4 (private) | £25‑£30 |
Best‑fit scenarios
Below is a quick guide to help you match a medication to your lifestyle and health goals.
- Daily oral routine, low cost: Cycrin or generic Provera. Both are covered by the NHS for menopausal HRT.
- Need for strict adherence (e.g., forgetful schedule): Depo‑Provera injection every three months eliminates daily pill fatigue.
- Desire for combined estrogen‑progestin therapy in one pill: Prempro or similar UK combos.
- Concern about synthetic progestin side‑effects: Naturogest offers a bioidentical alternative, though it may cost more.
- Women with a history of androgen‑sensitive conditions (e.g., acne, hirsutism): Avoid Norigynon due to higher androgenic activity; stick with MPA‑based options.
Key takeaways for clinicians
If you’re prescribing, keep these pointers in mind:
- Check the patient’s cardiovascular risk before adding any progestin to estrogen.
- Discuss administration preferences - many patients prefer a monthly tablet over a quarterly injection.
- Consider bone health: Depo‑Provera and Naturogest have documented benefits for bone density.
- Review cost: for most NHS patients, the generic Provera and branded Cycrin are free, making them first‑line choices.
- Monitor side‑effects regularly, especially mood changes, and be ready to switch if tolerance becomes an issue.

Frequently Asked Questions
Is Cycrin the same as Provera?
Yes. Both contain 10mg of medroxyprogesterone acetate. The difference is mainly branding and pricing; Provera is the generic version and is often slightly cheaper.
Can I switch from Cycrin to a bioidentical progesterone?
Switching is possible but should be done under medical supervision. Bioidentical options like Naturogest have different metabolism, so dose adjustments may be needed to maintain symptom control.
What are the risks of using Depo‑Provera for menopause?
Depo‑Provera provides steady progesterone levels, which can protect bone density. However, the injection can cause weight gain, mood swings, and occasional irregular bleeding. Discuss these with your doctor before starting.
Is there a difference in breast cancer risk between Cycrin and other progestins?
Large epidemiological studies show a modest increase in breast cancer risk with combined estrogen‑progestin therapy, regardless of the specific progestin. The absolute risk remains low, but individual factors (family history, BMI) matter more than the brand.
Which option is best for a woman on a tight budget?
For most UK patients, the NHS covers the generic Provera and the branded Cycrin at no cost. If you need a long‑acting solution, the initial cost of a Depo‑Provera injection is higher, but you only need to pay every three months.
Armed with this side‑by‑side view, you can decide whether Cycrin vs alternatives matters for your health goals, budget, and daily routine. Talk to your GP or pharmacist, weigh the pros and cons, and choose the option that feels right for you.

I must commend the thoroughness of this guide, though it's hard not to notice the obvious bias toward NHS‑covered options. While the prose reads like a consultant brochure, the facts remain sound. If you’re seeking a truly neutral comparison, you may want to weigh private‑pay alternatives more heavily. Nonetheless, the side‑effect tables are a commendable reference. In short, choose what fits your lifestyle, not what the flyer tells you to.
Calvin Smith
Wow, another masterpiece that treats hormone therapy like a cafeteria menu. You can pick Cycrin if you love monthly trips to the pharmacy, or Depo‑Provera if you fancy a quarterly needle party. The table of side‑effects reads like a horoscope for your uterus, every sign has a different risk. And let’s not forget the budget section – because nothing says ‘well‑being’ like counting pennies on the NHS. All jokes aside, the guide does hand you the data you need, even if it feels like a sales pitch in disguise. So, thank you for the glitter‑covered spreadsheet, it’s oddly useful. Keep the spoilers coming, we’ll keep the pills popping.
Mandie Scrivens
The grammar in the side‑effect table is flawless; however, the phrasing ‘Weight gain low‑moderate’ could be tightened to ‘Low‑moderate weight gain.’ Consistency makes the guide easier to scan.
Natasha Beynon
Great job on making such a dense topic approachable. I especially appreciate the inclusive language that avoids gendered assumptions. Keep supporting readers with clear, compassionate advice.

Here we go I am thrilled to dive into this hormone therapy showdown. The guide lays out options like a menu at a bustling diner. You can sip oral tablets like a morning coffee. Or you can get a quarterly injection that feels like a surprise gift. The cost section reads like a treasure map for the NHS wallet. I love how the bone health benefits are highlighted with pride. The side‑effect tables shine like a neon sign in the night. Every medication gets its own spotlight and that feels fair. The tone stays friendly even when the data gets heavy. I can imagine a patient scrolling through this at a clinic waiting room. The design uses boxes and colors that keep my eyes awake. The language, while informal, never drifts into slang that could confuse. The detail about Naturogest being bioidentical is a gem. The comparison of weight gain across drugs helps set realistic expectations. I would tell anyone reading this to bookmark the chart for future reference. In short this guide is a burst of energy for anyone navigating menopause therapy.
Oscar Brown
Your enthusiasm is commendable, yet one must examine the clinical underpinnings with rigor. The pharmacokinetic profile of medroxyprogesterone acetate, whether delivered orally or intramuscularly, presents distinct advantages that merit nuanced discussion. While the guide enumerates cost considerations succinctly, it omits the long‑term economic impact of bone density preservation. Moreover, the ethical dimension of prescribing brand‑name versus generic formulations deserves scrutiny. In sum, a balanced appraisal should integrate efficacy, safety, and societal cost, echoing the principles of evidence‑based medicine.
Benjamin Hamel
I find it curious that the guide celebrates NHS coverage without questioning the monopoly of a single health system. One could argue that private options, though costlier, often spur innovation and provide faster access to newer progestins. The comparison table, while exhaustive, seems to sideline emerging oral bioidentical preparations that may soon eclipse MPA derivatives. Furthermore, the emphasis on injection adherence glosses over patient autonomy and the psychological burden of needles. In short, the narrative leans heavily toward convenience at the expense of broader therapeutic horizons.
Christian James Wood
Your contrarian stance, while intellectually stimulating, overlooks the lived reality of women who cannot afford private prescriptions. The suggestion that newer agents are inherently superior disregards decades of safety data supporting Cycrin. Moreover, the tone implies that NHS decisions are driven by cost alone, which is an oversimplification. Ultimately, the best advice remains patient‑centered, not ideology‑driven.
Rebecca Ebstein
Wow, this guide really helped me feel more confident about my choices! I love that it breaks down teh options in a way that's easy to understand, even if the numbers sometimes feel overwhelming.
Krishna Garimella
The journey through hormone therapy mirrors the broader quest for balance in life; each option offers a different rhythm of harmony. Reflect on how the choice of Cycrin or Naturogest aligns with your personal values and long‑term goals. Let the data guide you, but let wisdom and self‑compassion decide. May you walk this path with clarity and grace.
