Sildenafil in women with sexual arousal disorder following spinal cord injury
Some benefits, especially in ability to achieve orgasm, were reported.
- Sildenafil's effect duration in women may range from 4 to 6 hours.
- It may help women experiencing low libido linked to blood flow issues.
- The drug’s efficacy in women is less predictable than in men.
- Female sexual dysfunction has multiple causes beyond blood flow.
Men and women who take selective or nonselective serotonin reuptake inhibitors (SRIs) commonly report sexual dysfunction; the main difficulties among women are orgasmic dysfunction and problems with arousal, including lubrication.
Other Treatments for Low Libido
Speak to your doctor about how drug interactions should be managed. Sildenafil is metabolized mainly by CYP3A4 and to some extent by CYP2C9. It also weakly inhibits CYP1A2, 2C(, 2C19, 2D^, 2E1, and 3A4. Any drug that is a substrate of one of these enzymes could potentially interact with sildenafil. In addition, taking sildenafil with too much alcohol can lead to orthostatic hypotension, which is a drop in blood pressure when you go from a sitting or lying down position to standing. Studies of selective phosphodiesterase type 5 inhibitors (sildenafil [Viagra], vardenafil [Levitra], and tadalafil [Cialis]) as therapy for women with sexual arousal disorder have produced mixed results.

Exclusion Criteria

May not be suitable for some people including those with angina, chest pain, other heart conditions, liver or kidney problems, blood or bleeding disorders, stomach ulcers, certain eye conditions, or a physical deformity of the penis (such as Peyronie's disease). Higher dosages of sildenafil are associated with a higher risk of death in children with PAH. For this reason, the FDA does not recommend use in children aged less than 18 years. May interact with some medications including certain antibiotics and antifungals, herbal remedies, HIV medicines, nitrates, and drugs used in the treatment of high blood pressure or prostate disorders.
Effects on sexual dysfunction
Sildenafil should not be taken with other PDE-5 inhibitors. The dosage may need to be reduced in people with kidney or liver disease. More research is needed to establish if sildenafil has a role in sexual dysfunction in women. Sildenafil offers no protection against sexually transmitted diseases. Note: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects. mean treatment time, 28 months), and had substantial sexual dysfunction associated with antidepressant use; they were randomized to sildenafil (50-100 mg) or to placebo; drugs were taken 1 to 2 hours before anticipated sexual activity.
- Future studies may clarify sildenafil’s effectiveness for women.
- Regulatory approval for women may be granted if proven safe.
- Personalized medicine approaches could enhance treatment outcomes.
- In the meantime, women should seek professional advice before use.
From baseline to 8 weeks, sildenafil-treated women reported a mean improvement of 1.9 points on a global sexual function

Blocking PDE-5 means increased levels of cGMP within the smooth muscles which promotes muscle relaxation and vasodilation (a widening of blood vessels). High levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of the blood vessels and muscles. Sildenafil belongs to the drug class called phosphodiesterase (PDE) type 5 inhibitors. Sildenafil (Viagra, Vybrique brands and generic) is used to treat erectile dysfunction (ED, impotence).

5. Tips
Taking these substances together can cause a sudden and dangerous drop in blood pressure. Always buy your ED medications from a reputable supplier as there are a lot of counterfeit products on the market. Certain lifestyle and psychological factors, such as smoking, drinking, and stress, can impact ED. Eliminating these - for example, staying more active, losing weight if you are overweight, reducing alcohol intake, stopping smoking, and reducing stress - may also help improve ED. Never take other ED medications at the same time as taking sildenafil.

Drinking alcohol after taking sildenafil may lower blood pressure and decrease sexual performance.

Eur. Urol.
Peak plasma concentrations of sildenafil are reached within 30 to 120 minutes of a single dose. Effects of sildenafil, when used for ED, are usually noticeable within 30 to 60 minutes of a single dose. When used to treat PAH, blood pressure-lowering effects are noticeable within one to two hours. Medicines that interact with sildenafil may either decrease its effect, affect how long it works, increase side effects, or have less of an effect when taken with sildenafil. An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. These results are more positive than those in prior studies, so further replication will be required before these drugs can be recommended for off-label use.
