About Feminax Ultra
  1. What is Feminax Ultra?

    The alternative treatment Naproxen 250mg is available to buy at Medicine Direct.

    Feminax Ultra is available to purchase without a prescription. It contains the active ingredient naproxen, which is a nonsteroidal anti-inflammatory used to reduce the pain and inflammation associated with a wide number of conditions, most commonly period pain.

    Is Feminax Ultra still available in the UK?

    Unfortunately, Feminax Ultra has been discontinued in the UK and is no longer manufactured as of 2020. 

    What is Feminax Ultra used to treat?

    Feminax Ultra is commonly used to treat period pain and menstrual cramps in women.

    It is a fast-acting medicine that provides pain relief during your period. Feminax Ultra is mostly used by women who are aged between 15 and 50 years old.

    For the most effective pain relief, it is best to take one tablet as soon as your period pain starts; Feminax Ultra will get to work on the pain immediately, allowing you to go about your daily life without discomfort.

    How does Feminax Ultra work?

    Feminax Ultra contains naproxen, which is a nonsteroidal anti-inflammatory drug (NSAID). Naproxen works by preventing your body from releasing hormones called prostaglandins, which contribute towards inflammation and can cause pain. By stopping the prostaglandins from being released, your pain will be eased significantly.

    Who can take Feminax Ultra?

    Feminax Ultra provides effective relief for women who suffer from period pain, but it may not be suitable for all women to take.

    Before you start to use this medication, please inform your doctor or pharmacist if any of the below apply to you:

    • You have a blood clotting disorder
    • You have lupus
    • You have high blood pressure
    • You have had an allergic reaction to naproxen or any other medication
    • You have any heart problems, including severe heart failure

    • You have Crohn's disease or ulcerative colitis
    • You have severe liver or kidney disease

    This list is not exhaustive. Always read the patient information leaflet for a complete list of reasons why Feminax Ultra may not be suitable for you.

    Can you buy Feminax Ultra over the counter?

    No, Feminax Ultra has been discontinued and is no longer for sale.

    Can you buy Feminax Ultra online in the UK?

    Feminax Ultra is no longer available from Medicine Direct. However, it is possible to buy Naproxen tablets from our pharmacy. Naproxen is the active ingredient contained in Feminax Ultra and can be used to provide effective relief from period pain.

    To buy Naproxen from our online pharmacy, all you need to do is complete an online consultation. One of our prescribers will review your condition and medical history through the answers you provide in an online questionnaire, to make sure Naproxen is safe for you.

    Feminax Ultra alternatives

    Naproxen is the active ingredient in Feminax Ultra and works in exactly the same way as this branded medicine. Naproxen is also available to order from Medicine Direct.

    You can also buy Mefenamic Acid 500mg tablets and the branded version of this medicine, Ponstan, which are also highly effective in relieving period pain.

  2. Feminax Ultra Dosage

    Always read the patient information leaflet thoroughly before taking Feminax Ultra. Please do not hesitate to speak to your pharmacist if you are not sure of how to take it.

    You should take one tablet as soon as the pain begins to appear. Swallow the tablets whole with a drink of water.

    On the first day, take two tablets. If required, you can take one tablet between 6 and 8 hours later.

    On the second day, if required, take one tablet every 6 to 8 hours. This dose can be repeated on the third day if you still have period pain.

    Always ensure you inform your doctor or pharmacist of any medicines you are already using before you start to take Feminax Ultra. This includes both prescription and non-prescription medication, herbal remedies, vitamins and supplements.

    Pregnancy and breastfeeding

    Feminax Ultra is not normally recommended to be taken by women who are currently pregnant, particularly if you are more than 30 weeks pregnant. If this is the case, you should only take Feminax Ultra if it is prescribed by a doctor.

    There is a link between birth defects and taking naproxen. There may also be a link between this drug and miscarriages in early pregnancy.

    If you are currently pregnant, think you might be pregnant, or are trying to get pregnant, you should first inform your doctor or pharmacist before taking this medicine.

    Paracetamol is normally the safest medicine to use for pain while pregnant.

    Similarly, if you are breastfeeding, it is usually safer to use ibuprofen. Tell your doctor if you are breastfeeding before taking this medicine.
