Can Prelox Improve Sexual Function for Women?

Some studies have shown positive results – there have been some scientific studies conducted to establish whether Prelox is effective at improving female sexual dysfunction. One study showed that healthy women of late reproductive age, who were supplemented for 8 weeks with Prelox saw their sexual function improve significantly. The herbal supplement was also well tolerated and no one needed to stop the trial due to adverse effects. However this study was very small and therefore further studies are needed to confirm if Prelox is effective and safe.

It could work well in post-menopausal women – an earlier study carried out in 2012, found that post-menopausal women may benefit from taking Prelox. In fact, the study found that Prelox was significantly more effective than a placebo and that the results were significant after just four weeks. This study also reported no adverse effects and that Prelox was well-tolerated by the participants. Once again this study was of very small numbers of women and further studies are needed.

Prelox contains ingredients that are related to sexual function in women – nitric oxide (NO) is known to be a key media for sexual function. One of the ingredients of Prelox, L-arginine, is a precursor of NO. Therefore, an increase in L-arginine could increase NO which in turn could help improve sexual function. However further study of this theory is needed to confirm whether this is the case.

A doctor won't recommend Prelox – your doctor will not prescribe you Prelox as it is a herbal supplement which is not licensed and is not available on prescription. However, there may be alternative medications or treatments available from your doctor depending on the cause of your sexual problems.

Is it Worth Trying Prelox?

It might be, as long as it's safe for you – it may be worth trying Prelox but take care to read the label to ensure you are not allergic to any of the ingredients. However, it is worth noting that the effectiveness of Prelox may be a placebo effect. In other words, it may work because of your belief in its effectiveness rather than because of its active ingredients. As mentioned above, there are scientific studies which show that Prelox can be effective in improving the sexual function of both women of pre and post-menopausal age. However it is important to balance this against the risks of taking an unregulated product.

Potential side effects of reported by the manufacturers of Prelox include:

  • gastro-intestinal discomfort
  • headache
  • nausea
  • dizziness

You could be disappointed by the results – the cost of Prelox may not feel worth it, especially if it does not work for you. Furthermore, if a treatment like Prelox doesn’t work it can be quite disappointing or frustrating.

Why is Prelox Not a Prescription Medication?

Why isn't it prescribed by doctors? – Prelox is not a pharmaceutical medication and so is classed as a supplement and requires no prescription. Prelox is not a licenced medication, and therefore has not been through this trial and regulation process to prove that it is safe and effective

It still has the risk of side effects – Prelox has no proven medical effect but there are still risks of side effects. This is because the ingredients can interact with your body or other medications you may take causing an adverse or allergic reaction. Plus, as we noted above some of the ingredients can cause side effects just like prescription medications. If you take any other medications or have any health conditions you should always check with your doctor if Prelox is safe for you to try.

How does something become a licensed medications? – before a medication can become available for treatment in the UK, it must go through a strict process. Usually, this involves researching the medication in a laboratory and then testing it in clinical trials. If successful, the medication may be granted a licence so that it can be made available for use.The licence confirms the health condition the medication should be used for and the recommended dosage.

Are there Medications That Treat Sexual Dysfunction in Women?

There is one licensed in the US – but in the UK there are currently no medications that are licensed specifically for the treatment of sexual dysfunction in women. Many people will have heard of a medication called flibanserin (Addyi), which is licensed in the USA for this. It has been developed for women who have not yet been through the menopause and have acquired, generalized hypoactive sexual desire disorder or HSDD.

What are the effects of Addyi? – it is thought that Addyi works on the part of the brain involved in sexual desire and interest, but how it works is not fully understood. Some studies claim that the effectiveness of Addyi is limited and that it has some potentially unpleasant side effects, including:

  • dizziness
  • nausea
  • fatigue
  • sleepiness

What other alternatives are there? – Depending on the cause of your sexual problems your doctor may be able to suggest an appropriate treatment. For example there is some evidence that testosterone therapy can improve low sexual desire however this is not licensed in women.
