Safety and efficacy of sildenafil citrate for the treatment of female sexual arousal disorder: a double-blind, placebo controlled study.
Do not take sildenafil with recreational drugs such as "poppers". 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. Do not take Viagra while taking Revatio and vice-versa. Seek urgent medical advice if an allergic reaction, sudden vision loss, or painful erections lasting more than four hours occur. Drinking alcohol after taking sildenafil may lower blood pressure and decrease sexual performance. If you are a woman of childbearing age taking sildenafil (brand Revatio) for PAH, then tell your doctor if you become pregnant or are intending to become pregnant.
It is not known if sildenafil is distributed into breast milk. 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. Female sexual dysfunction (FSD) affects up to one third of women in the U.S., often involving sildenafil 100mg blue pill low libido, arousal difficulties, and pain during intercourse.

Viagra (sildenafil citrate) is approved to treat erectile dysfunction in men but is sometimes prescribed off‑label in women.
Sexual arousal and orgasm in women: effects of spinal cord injury. Arch Sex Behav 2004; 33: 295-302. Hultling C, Giuliano F, Quirk F, Pen ˜a B, Mishra A, Smith MD. Quirk FH, Heiman JR, Rosen RC, Laan E, Smith MD, Boolell M. Development of a sexual function questionnaire for clinical trials of female sexual dysfunction. Evidence is limited and mixed, and FSD often has multifactorial causes including hormonal changes, medications, relationship issues, and psychological factors. By blocking PDE‑5, it increases blood flow to genital tissues: In women, enhanced blood flow to the clitoris and labia may increase lubrication, sensitivity, and genital engorgement following sexual stimulation.
An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. 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. Symptoms include a headache, dizziness, or fainting when standing. Antacids, such as magnesium hydroxide or aluminum hydroxide may also affect the absorption of sildenafil. Grapefruit juice may also increase the side effects of sildenafil. Note that this list is not all-inclusive and includes only common medications that may interact with sildenafil.
You should refer to the prescribing information for sildenafil for a complete list of interactions. Cialis vs Viagra - What's the difference between them? Do you know these 11 amazing facts about Viagra? Is generic Viagra sildenafil citrate chewable tablets available in the U.S.? Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use sildenafil only for the indication prescribed. Sildenafil is also available under the brand Revatio at lower doses for pulmonary hypertension in both sexes. Some trials suggest benefit for women with arousal problems or SSRI‑induced sexual side effects, particularly in postmenopausal women.
| Aspect | Description | Typical Dosage | Onset of Action |
|---|---|---|---|
| Pharmacology | PDE5 inhibitor originally for male ED | 25-100 mg | 30-60 minutes |
| Approved Use | Not officially approved for women, experimental use | N/A | N/A |
| Common Side Effects | Headache, flushing, nasal congestion | N/A | N/A |
| Contraindications | Nitrates, certain heart conditions | N/A | N/A |
Other studies show minimal or no improvement. More research is needed to determine which subgroups of women might benefit.
Methods: 129 women were randomized and treated with sildenafil or matching placebo. The Sexual Function Questionnaire, the Sexual Quality of Life Questionnaire-Female, a global efficacy question and Sexual Distress Question were also assessed. Results: Sildenafil-treated women and placebo-treated women had an increase in their percentage of sexual activities throughout the course of the study, with no statistically significant difference between groups in the percentage of successful sexual activities at end of treatment versus baseline. There were also no statistically significant differences between sildenafil-and placebo-treated women on the aforementioned measures. Conclusion: The results of this study are similar to other reports regarding a lack of clinically meaningful benefit of sildenafil in other populations of women.

Side effects include dizziness, fatigue, nausea, dry mouth, and insomnia. Vyleesi (bremelanotide): injected at least 45 minutes before sexual activity, up to 8 doses per month, for premenopausal women with low desire. Common side effects are nausea, flushing, injection site reactions, headache, and fatigue.

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. 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. In this multisite trial, funded by sildenafil´s manufacturer, researchers enrolled 98 women (mean age, 37) who had normal sexual function before treatment for depression, were being treated successfully with SRIs (usually fluoxetine, sertraline, or paroxetine; 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.
From baseline to 8 weeks, sildenafil-treated women reported a mean improvement of 1.9 points on a global sexual function scale (range, 1-7 points) compared with 1.1 points for those who received placebo — a statistically and clinically significant difference. Only 28% of sildenafil-treated women noted no improvement, compared with 73% of those who received placebo. Treatment also resulted in significant improvement in ability to achieve orgasm as measured on three additional scales, as well as near-significant improvements in several measures of satisfaction and enjoyment. Significant nitric oxide (NO) and NO synthase activity has been found in female genital tissue, suggesting a plausible biological explanation for how drugs such as sildenafil, which are used in erectile dysfunction, could also affect female sexual function. 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.
