How to tell if an online menopause clinic is trustworthy: red flags and what it should include

You can trust an online menopause clinic when three things happen. A doctor reviews your medical history before anything is decided. Any prescription is dispensed by an authorised pharmacy. And there is follow-up afterwards. The clearest red flags are these: asking every woman for hormone tests whatever her age, offering saliva tests to ‘fine-tune’ your hormones, selling made-to-measure ‘bioidentical’ hormones, or sending you a prescription-only medicine without going through a pharmacy. Below we explain each warning sign, along with what clinical guidelines and Spanish regulations say.

Telemedicine has been genuinely useful for many women who can't get an appointment to talk about hot flushes, insomnia or changes to their periods. But it has also brought websites that blur the line between medicine and marketing. You don't need to be a doctor to tell them apart. You only need to know four or five things a reputable clinic always does, and a few it should never do.

What a reputable online menopause clinic should include

Treating the menopause is not just a matter of choosing a product. A proper consultation always follows the same steps, whether it takes place in person or by video call.

• A genuine medical assessment. You should be asked about your symptoms, your periods, your personal and family medical history, any medication you take and what you hope to get from treatment. A form that leads straight to a shopping basket is not an assessment.
• A diagnosis based on clinical judgement. From the age of 45, guidelines do not require blood tests to confirm perimenopause or menopause. Before that age, a specific test may make sense.
• A prescription written by a doctor, only when appropriate. It should come with an explanation of the benefits, risks and alternatives, including non-hormonal options.
• Dispensing by an authorised pharmacy. In Spain, prescription-only medicines cannot be sold at a distance.
• Follow-up: check-ins to see how you are responding, to adjust or stop treatment and to pick up any side effects.

To understand what a doctor weighs up before suggesting hormone therapy, and when it isn't a good idea, see our guide to menopausal hormone therapy: who it's for and its real risks. For how all this fits into the legal framework for remote consultations, see how menopause treatment by telemedicine works in Spain.

Red flags: what a trustworthy clinic doesn't do

1. It insists on a hormone test to tell you whether you're in the menopause

This is probably the most widespread myth, and some websites use it to sell you a package of tests. The UK's NICE NG23 guideline, updated in 2024, is clear. In women over 45 with symptoms, perimenopause and menopause are diagnosed clinically and no blood tests are needed. Perimenopause is recognised by hot flushes and irregular periods. Menopause is recognised after 12 months without a period or, in women who have no uterus, by symptoms.

NICE also advises against using anti-Müllerian hormone, inhibin A, inhibin B or oestradiol to diagnose perimenopause or menopause from the age of 45. It says FSH testing should only be considered in two cases: women aged 40 to 45 with symptoms, and women under 40 in whom menopause is suspected. FSH is no longer reliable if the woman is using combined hormonal contraceptives or high-dose progestogens.

The detail matters: a clinic asking for tests is not a bad sign in itself. It becomes one when the clinic asks everyone, regardless of age or circumstances, or when the test is the product. If you are under 40 and suspect your periods are stopping, things are different and need investigating. We cover this in early menopause or premature ovarian insufficiency.

2. It offers saliva hormone tests to ‘fine-tune’ your treatment

Saliva hormone tests look appealing. You do them at home and they promise to reveal your ‘imbalance’. But the Endocrine Society, The Menopause Society (formerly NAMS) and the British Menopause Society all advise against using them to guide treatment. There is no evidence that saliva levels match blood levels or symptoms, and laboratory methods are not standardised. In the menopause, treatment is adjusted according to how your symptoms respond, not by chasing a number in a saliva sample.

3. It sells made-to-measure ‘bioidentical’ hormones

Two things are often deliberately confused here, and it is worth separating them. There are authorised medicines containing hormones with the same structure as those your body makes, such as estradiol and micronised progesterone. They have a summary of product characteristics, manufacturing controls and clinical studies behind them. We explain them in estradiol and micronised progesterone: what modern hormone therapy looks like.

Custom-compounded formulations, which some websites market as more natural and safer, are something else entirely. A 2021 review of the positions taken by scientific societies found no evidence that they are more effective or safer than authorised treatments. It also found that their purity and potency vary, which carries risks. ACOG, the Endocrine Society and NAMS advise against them. A patient information sheet based on Healthwise describes a US study in which the same compounded prescriptions were bought from pharmacies in different states. A third had the wrong oestrogen content, with deviations of up to 250%.

4. It sends you the medicine without a prescription, or from a website that isn't an authorised pharmacy

According to the AEMPS (the Spanish Agency of Medicines and Medical Devices) and the Spanish Ministry of Health, only non-prescription medicines can be sold at a distance in Spain. They can only be sold through authorised pharmacies that display the EU common logo. That logo links to the official register for the relevant autonomous community (region). Menopausal hormone therapy requires a prescription in Spain. A website that sells it and posts it straight to your home, without a prescription or an authorised pharmacy, is breaking the law, however professional it looks.

The proper route is the opposite. The doctor prescribes, the prescription is recorded and you collect the medicine from a pharmacy. If someone offers to skip that step, the problem isn't only a legal one: you also have no way of knowing what you are actually taking.

5. It uses headlines like ‘the FDA says hormone therapy no longer carries any risks’

On 10 November 2025, the US Food and Drug Administration (FDA) announced that it would remove the boxed warning from more than 20 hormone therapy products. It would also take references to the risk of cardiovascular disease, breast cancer and probable dementia out of their labelling. This is significant news, but it has limits that a reputable clinic will explain. The decision applies to the United States, and the warning about endometrial cancer with oestrogen-only treatment remains in place. There is no record of the AEMPS or the EMA having changed the European summaries of product characteristics in the same way. Anyone using the news to tell you there is nothing to weigh up is selling, not informing.

6. There is no identifiable doctor and no follow-up

Something essential is missing in three situations: you don't know who is looking after you, the ‘consultation’ is an automated questionnaire, or nobody asks how you are getting on after your first purchase. The first few months of any hormone treatment bring questions and adjustments. A clinic that doesn't allow for them is selling a product, not treating you.

How to check an online pharmacy in Spain

Some things can legally be bought at a distance, namely non-prescription medicines. For these, there are two simple checks. First, look for the EU common logo on the website and click it. It should take you to the official register for your autonomous community, where the pharmacy must be listed. Second, look the pharmacy up on Distafarma, the AEMPS platform for checking whether a pharmacy is authorised to sell at a distance. If the logo doesn't link to an official site or the pharmacy isn't listed, don't buy.

Are online medical consultations regulated in Spain?

Yes. Remote care is part of medical practice and carries the same ethical obligations. The Code of Medical Ethics of the Organización Médica Colegial (the Spanish General Medical Council) was approved in 2022 and replaces the 2011 code. For the first time, it includes a chapter dedicated to telemedicine. In practice, the things that matter to you as a patient are the same as in a face-to-face appointment. A doctor should see you and have the information needed to make a decision. When your case needs a physical examination or tests, they should tell you and refer you.

Key points and next step

You can spot a trustworthy online menopause clinic by what it does: a medical assessment, a prescription only when appropriate, an authorised pharmacy and follow-up. You can also spot it by what it doesn't do: unnecessary tests after 45, saliva tests, custom formulations or posting medicines without a prescription. In Spain, medical treatment for the menopause by telemedicine with these safeguards is available today. At AiON, a registered doctor assesses your case before anything else and prescribes only if treatment is indicated. They then support you with ongoing follow-up.
