# Qsymia — why it is not prescribed in most of the EU

> Qsymia (phentermine/topiramate): why the EMA refused EU-wide approval, where it is sold under the name Qsiva, and EU-authorised alternatives.

Qsymia is the United States brand name for a capsule that combines phentermine and topiramate, approved there in July 2012. Hi-Doctor does not prescribe it: it has no EU-wide marketing authorisation, so in most member states — including Spain — a doctor cannot prescribe it for weight loss.

## What is Qsymia?

Qsymia is a once-daily capsule combining phentermine, which dampens appetite, with a slow-release form of topiramate — an epilepsy and migraine medicine that also reduces how much people want to eat.

<Note>
  In Europe the same product is called Qsiva.
</Note>

## Why it is not marketed across the EU

There is no EU-wide approval. The European Medicines Agency refused the Europe-wide application in 2013 because of concerns about long-term effects on the heart, on mood, and on memory and attention. The manufacturer later obtained national approvals through a separate route led by Sweden, and the product is on the market in a small number of northern European countries — Sweden, Denmark, Finland and Poland, plus Norway and Iceland.

<Warning>
  Qsymia has no EU marketing authorisation for weight loss in most member states, including Spain. No doctor there — including ours — can prescribe it for this use. It may be an approved medicine for something else, or approved in another country, but that does not make it prescribable here.
</Warning>

## What the studies reported

<Note>
  Every NCT identifier links to its ClinicalTrials.gov record. A readout is not the same as peer-reviewed publication.
</Note>

The CONQUER trial ran for 56 weeks across 93 centres in the United States only. When the EMA reviewed this programme, it judged that a cardiovascular outcomes trial would be needed before it could accept the long-term safety of the combination — and that trial has not been published.

## What has been reported

| Effect                          | Higher dose | Lower dose | Placebo |
| ------------------------------- | ----------- | ---------- | ------- |
| Dry mouth                       | 21%         | 13%        | 2%      |
| Pins and needles (paraesthesia) | 21%         | 14%        | 2%      |

Figures are from the CONQUER trial. The EU product information also lists constipation, dizziness, insomnia, depression and anxiety as reported effects, along with effects on the heart and circulation, and a risk in pregnancy — none of these are quantified in the harvested source for this page.

## Why buying Qsymia online is not a shortcut

A medicine bought online without an EU marketing authorisation and without a doctor's review carries risks the CONQUER trial and the EMA's own assessment flag directly — including the unresolved cardiovascular question that led to the EU refusal. Check for the EU common logo on any online pharmacy before buying medication anywhere.

## What can I take instead?

Semaglutide is approved in the EU, has published peer-reviewed trial results, and can be prescribed today if a doctor decides it suits you. A licensed doctor decides case by case — Hi-Doctor never prescribes without evaluation.

## How Hi-Doctor handles it

Weight-loss treatment runs as an ongoing plan, with a first consultation and doctor-reviewed renewals. See the full set of available options on the [treatment areas page](/library/treatments/weight-management-program), and [pricing](/essentials/pricing) for how the plan is billed.

## Start a consultation

<Card title="Weight-loss consultation" icon="stethoscope" href="https://hi-doctor.ai/consultation/weight-loss/1">
  Answer the weight-loss questionnaire and a registered doctor reviews it.
  They decide whether treatment is appropriate, which one, and at what dose —
  and declining is a normal outcome. See [what it costs](/essentials/pricing)
  and [how the review works](/essentials/how-it-works).
