[24] This cyanopsia can be explained because sildenafil, while selective for PDE5, does have some affinity for PDE6, which is the phosphodiesterase found in the retina.

[8] Sildenafil should not be taken by people on nitric oxide donors such as nitroglycerin, as this may result in a serious drop in blood pressure. Sildenafil acts by blocking phosphodiesterase 5 (PDE5), an enzyme that promotes breakdown of cGMP, which regulates blood flow in the penis. [8] It requires sexual arousal to work, and does not by itself cause or increase sexual arousal. [8] It also results in dilation of the blood vessels in the lungs. Pfizer originally discovered the medication in 1989 while looking for a treatment for angina.
[11] It was approved for medical use in the United States and in the European Union in 1998. [5][8][11][12] In 2023, it was the 151st most commonly prescribed medication in the United States, with more than 3 million prescriptions. [13][14] It is available as a generic medication. [15][16] In the United Kingdom, it is available as a pharmacy medicine. The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete sexual intercourse).
Its use is now one of the standard treatments for erectile dysfunction, including for males with diabetes mellitus. Tentative evidence suggests that sildenafil may help males who experience antidepressant-induced erectile dysfunction. While sildenafil improves some markers of disease in people with pulmonary arterial hypertension, it does not appear to affect the risk of death or serious side effects. Sildenafil and other PDE5 inhibitors are used off-label to alleviate vasospasm and treat severe ischemia and ulcers in fingers and toes for people with secondary Raynaud's phenomenon;[9][21] these drugs have moderate efficacy for reducing the frequency and duration of vasospastic episodes. [9] As of 2016,[update] their role more generally in Raynaud's was not clear. Some complained of blurriness and loss of peripheral vision.

In July 2005, the US Food and Drug Administration (FDA) updated labeling for tadalafil (Cialis), vardenafil (Levitra), and sildenafil (Viagra) to reflect a small number of post-marketing reports of sudden vision loss, while acknowledging that "...it is not possible to determine whether these oral medicines for erectile dysfunction were the cause of the loss of eyesight or whether the problem is related to other factors such as high blood pressure or diabetes, or to a combination of these problems.
The side effects are usually mild and temporary, including headache and dizziness. It may not be suitable for everyone, particularly if emotional or psychological concerns are the primary source of sexual problems. However, women with sexual dysfunction can also consider other alternatives to Sildenafil like Flibanserin, Bremelanotide, and Lovegra after consulting their doctor. Sildenafil usually takes 30–60 minutes to show its effect in women. Its effect depends on individual metabolism, food intake, and dosage.
It only works with sexual stimulation, as it enhances physical arousal but does not boost desire on its own. No, daily use of Sildenafil is generally not recommended unless specifically advised to do so by a doctor. Research on long-term daily use in women is limited, and frequent dosing may increase side effects or interactions. Hence, occasional, as-needed use is usually preferred. There is no officially approved dose of Sildenafil for women.
Doctors usually recommend a low dose, such as 25–50 mg, depending on an individual’s health and response. Self-adjusting the dose is not recommended. Similar to men, the effects of Sildenafil in women typically last 4–6 hours; however, this duration can vary depending on individual metabolism, health conditions, and dosage. Its benefits require sexual stimulation, and the intensity of effects may gradually decrease as the medication wears off. No, it is not recommended for a woman to take her husband’s Viagra, as it is not meant to be used by women. "[25] A careful review of pooled data from clinical trials containing well documented information about the dose and duration of exposure to the drug for a large number of patients, yields no evidence for an increased risk of non-arteritic anterior ischemic optic neuropathy or other adverse ocular events associated with PDE5 inhibitor use.
Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss.
Marketed under the brand name Addyi, Flibanserin is a daily oral medicine approved for the treatment of decreased sexual desire in premenopausal women, as well as some postmenopausal women up to the age of 65. It works by regulating brain chemicals like serotonin and dopamine to gradually boost desire. However, it takes constant usage over several weeks and is only approved for women with HSDD. It is a self-administered subcutaneous (under the skin) injection that is taken on demand before sexual activity. Sold under the brand Vyleesi, Bremelanotide is an approved Sildenafil alternative for premenopausal women with poor sexual drive.
It acts by stimulating melanocortin receptors to increase sexual desire, with effects visible within hours and lasting up to a day. Lovegra, often known as female Viagra, is a Sildenafil-based medication, marketed to help women with FSAD. It works by increasing blood flow to the genital area, which can improve sensitivity, natural lubrication, and responsiveness to sexual stimulation when taken before intimacy. However, unlike Flibanserin and Bremelanotide, its usage in women is not approved by major authorities such as the FDA. Due to a lack of evidence of its efficacy and safety, it is advisable to consult a certified healthcare provider before its safe and effective usage.
Although not approved by the FDA, Sildenafil can be used off-label to address sexual health issues, particularly Female Sexual Arousal Disorder in some women. It can be quite helpful for women experiencing difficulties with sexual arousal, particularly those with physical causes like poor blood flow or lubrication problems. It works by boosting blood flow to the vaginal region, potentially improving sensitivity, lubrication, and the ability to achieve orgasm. While clinical trials show mixed outcomes, many women, particularly those who have experienced postmenopausal symptoms or who have had sexual adverse effects from antidepressants, have benefited from its usage. Sildenafil for women is generally considered safe when used under the guidance of a medical professional. [4] In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss.
While Sildenafil in Viagra is sometimes used off-label for women, her husband’s dose can be unsafe. It can cause serious side effects like irregular heartbeat or severe interactions with other medications and health conditions.

Sildenafil, sold under the brand name Viagra among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. [4][8] It is also sometimes used off-label for the treatment of certain symptoms in secondary Raynaud's phenomenon. [9] It is unclear if it is effective for treating sexual dysfunction in females.
[8] It can be taken orally (swallowed by mouth), intravenously (injection into a vein), or through the sublingual route (dissolved under the tongue). [8][10] Onset when taken orally is typically within twenty minutes and lasts for about two hours. Common side effects include headaches, heartburn, and flushed skin. [8] Caution is advised in those with cardiovascular disease. [8] Rare but serious side effects include vision problems, hearing loss, and prolonged erection (priapism) that can lead to damage to the penis. Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection.
Sildenafil has shown some potential for improving exercise performance at high altitudes. However, its overall efficacy is not clear. Sildenafil has been studied for high-altitude pulmonary edema (HAPE), but its use is currently not recommended for that indication. In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, indigestion, nasal congestion, and impaired vision, including photophobia and blurred vision. [4] Some sildenafil users have complained of seeing everything tinted blue (cyanopsia). Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects.
Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours.
