Buy Qsymia (phentermine topiramate). Qsiva is the European name for Qsymia, an appetite suppressant approve in the United States. An application for Qsiva was rejected by the European Medicines Agency.

Qsiva is designe to help obese patients reduce their appetite and feel satisfied with less food. It comes in capsule form and is consume daily.
How does Qsiva work?
Qsiva contains two active ingredients, phentermine and topiramate. Phentermine use to be a commonly prescribe slimming medication. Until about a decade ago, when concerns were raise about its impact on long-term health and whether it is addictive. Phentermine is no longer generally prescribe in the UK but there are some specialist slimming clinics that prescribe this medication for very short-term use. Phentermine is still the most commonly prescribe weight loss medication in the United States. Topiramate approve in 1996 as a treatment for epilepsy and more recently as a treatment for migraine prevention.
Topiramate works through GABA receptors in the brain to increase feelings of satiety and fullness. Phentermine stimulates the release of the neurotransmitter noradrenalin, which reduces appetite. The combination of Topiramate with Phentermine appears to increase Topiramate’s window of effectiveness.

Qsiva has gone through two separate phase. III clinical trials is require by the FDA and results from the trials show that it is an effective aid to weight loss in obese patients.

- 84% of patients on the highest dose lost 5% or more of their total body weight, with 59% on the lower dose achieving the same results, compared with only 26% in the placebo group achieving the same result

Is Qsiva safe?
As with any medication, Qsiva does seem to have some side effects in some patients. The most common is dry mouth, tingling sensations, constipation, alter taste and insomnia. The medication did not seem to cause problems with mood, depression or suicidal ideation.
There had been concern about side effects reported previously with Phentermine. Raise blood pressure – and Topiramate, namely cognitive problems and depression. However both drugs are present in Qsiva in very low doses and there has been no indication in the clinical trial data that the medication causes any of these, or any other, serious side effects.
The Online Clinic has always opposed the prescription of Phentermine on its own but if this new sustained release formulation in combination with Topiramate is deemed to be safe and effective then we will give serious consideration to prescribing it once the medication has been approved by the European Medicines Agency and the MHRA.
When will Qsiva be available?
Qsymia is available in the United States through certain physicians but it can be online. If a European license is again applied for, we would expect Qsiva to become available in 2015 in the EU.
