Thousands of women may be putting their health at risk by taking erectile dysfunction drugs such as Viagra in a bid to perk up their sex lives, experts have warned. 

A revealing survey by LloydsPharmacy Online Doctor found up to 40 per cent of women suffered flagging libidos, or found sex uncomfortable or painful. 

Yet experts sounded the alarm after one in ten admitted they believed Viagra—which has only been tested for use by men—was safe for them to take. 

Viagra works by relaxing blood vessels which, in men, helps improve erections. 

While generally safe in rare cases, the drug can cause heart-related side effects, especially in those with pre-existing heart conditions or who take certain medications.

These include heart attack, stroke, irregular heartbeat, and low blood pressure.

LloydsPharmacy Online Doctor GP, Dr Bhavini Shah, warned women against taking the drug in the mistaken belief it could improve their bedroom performance.

‘It’s thought, or hoped, by some, that Viagra may increase sexual pleasure in women by increasing blood flow to the female genital area,’ said Mr Shah.

‘However, the medical trials to date have failed to produce significant evidence that Viagra works for women. 

‘Viagra has been shown to be ineffective in women who have sexual difficulties.’

The survey, which involved questioning 500 women across the UK, found eight in ten struggled to achieve orgasm, with a quarter struggling often. 

Almost half said they didn’t enjoy sex as much as they thought they should.

Dr Bhavini Shah said: ‘Female sexual dysfunction, or FSD, affects around 40 per cent on women. 

‘This may cause loss of libido, difficulties reaching orgasm or cause sex to be uncomfortable or painful. 

‘We diagnose FSD if these problems have occurred for more than six months.

‘It can be triggered by illness, life experiences—during pregnancy, after having a baby—stress, hormonal changes like menopause, medication side-effects, cancer treatment, chronic illness or depression.

‘It can also ‘sneak up on you’ for no apparent or obvious reason.’

She adds: ‘Many women have difficulties with sex at some stage in their life and for most this is temporary. 

‘But if you’re finding sex is more of a chore than a pleasure, these feelings have been occurring for a long time, or it’s affecting your relationship you could be experiencing female sexual dysfunction.’

Treatments for FDS include counselling or psychotherapy, reducing alcohol consumption and pelvic floor exercises.

If medication may be causing the issue, there might be a way to switch to another drug or reduce the dose, under the guidance of a doctor. 

While Viagra and other erectile dysfunction drugs are proven to be effective in men, a similar drug is yet to be made available to women.

A number of tablets have been trialled but have failed to produce consistent results.

Part of the reason, say experts, is that FSD is a far more complex condition that the male equivalent, erectile dysfunction.  

Dr Shah said: ‘FSD may not occur in every situation and with every partner, or only in some situations or with some partners. It may resolve by itself, or it may need help.

‘To find the reasons for sexual dysfunction you may need to look at physical, psychological and relationship factors.

‘If you think you might have FSD, try and identify the aspects of sex that are difficult for you and/or are causing distress in your relationship. 

‘Is it a lack of libido? Do you find it difficult to orgasm or do you experience pain when having sex?

‘Being clear about what the issues are will help talking to your GP.’
