Xenical Prescription

How to get a prescription for Xenical

To get a prescription for Xenical (orlistat), you will need to see a doctor, such as your general practitioner, a gastroenterologist, or a weight loss (bariatric) physician at the surgery.

After your examination with the doctor and getting your prescription you may retrieve your Xenical medication at a retail pharmacy or online pharmacy in the UK.

Be aware that although the over-the-counter medication Alli also contains orlistat, Alli has a lower dose of orlistat than Xenical does.

Getting a Xenical prescription for the first time

To get a prescription for Xenical for the first time, your doctor will likely conduct the following to make sure that Xenical is the right medication for you:

  • Take your medical history
  • Do a physical examination, including measuring your height, body mass index (BMI) and waist
  • Order laboratory tests
  • Find out what other medications you are taking

Your BMI, which is a measure of how overweight you are, will be an important factor in determining whether or not you are a candidate for a Xenical prescription. A BMI is a proportion (ratio) of your weight to your height. In a healthy adult, normal BMI is 18.5 to 24.9 kg/m. But, people who are muscular may have higher BMIs.

Generally, to be a candidate for a Xenical prescription you must be at least 12 years of age and have either one of the following conditions:

  • A BMI that is at least 30
  • A BMI that is least 28 AND a weight-related diagnosis, such as high blood pressure, high level of fat in the blood or diabetes

If your doctor decides to give you a prescription for Xenical, the doctor will explain that Xenical needs to be taken with a weight loss program, including a low-fat diet and regular exercise, in order for Xenical to be effective and to avoid side effects.

The prescription consists of a green slip, which you give to the pharmacist and a white side (called the re-order form), showing a list of drugs that you are allowed to obtain by repeat prescriptions.

Some retail pharmacies require that the pharmacist check your weight, height and blood pressure for free in a private consultation room prior to dispensing the Xenical medication.

Also, once you have your prescription you may order Xenical from an online pharmacy in the UK.

Getting repeat prescriptions of Xenical

Typically for Xenical your doctor will likely determine how much weight you have lost after three months before deciding whether or not to continue prescribing Xenical for you. If you have lost at least 5% of your starting weight by the three months, your doctor will consider continuing your prescription.

Prescription medicines that your doctor has authorized that you can receive for a designated timeframe, typically from 6 to 12 months, without having to see your doctor in person again are called repeat prescriptions.

To get repeat dispensing of your Xcytrin prescription, you should request it from your prescriber in person or by phone, stating that you would like to be able to collect your Xenical prescription monthly from a retail pharmacy or online pharmacy.

If you are obtaining your repeat prescription of Xenical from a retail pharmacy, you usually have to mark the re-order form and present it to the pharmacy, or have it arrive by mail at the pharmacy, or order it through the online service of the retail pharmacy two to five days before you run out of the medication and need to pick up the repeat medication.

If you need your repeat prescription of Xenical urgently, call or visit the prescriber as soon as possible. A general practitioner or nurse at a local NHS walk-in-centre or an out-of-hours health facility may be able to provide you with an emergency prescription, or perhaps even a supply of your Xenical.

If the prescriber or another healthcare professional is unavailable, a pharmacist may be able to provide one treatment cycle of Xenical if:

  • You visit the pharmacist in person at least two working days prior to running out of the medication
  • You prove that you have been prescribed Xenical previously
  • The pharmacist agrees that you need the Xenical immediately

In certain circumstances the pharmacist may be able to provide you with a small supply of the prescription medication until you can visit your healthcare professional in person. Realise, however, that an emergency supply of a prescription is not covered by the NHS, so that the pharmacy is allowed to charge for the service.

Remember that you should not change or stop your taking of Xenical without speaking to your doctor and pharmacist first.
