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. "[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.

What causes erection problems (also called erectile dysfunction or ED) in one man may not affect another man. Talk to your health care provider if you think that a medicine or drug is having a negative effect on your sexual performance. Never stop taking any medicine without first talking to your provider. Some medicines may lead to life-threatening reactions if you do not take care when stopping or changing them. The following is a list of some medicines and drugs that may cause erectile dysfunction (ED) in men.

Quit smoking

There may be additional drugs other than those on this list that can cause erection difficulties. Antidepressants and other medicines for mental health conditions Antihistamine medicines (certain classes of antihistamines are also used to treat heartburn): High blood pressure medicines and diuretics (water pills): Thiazides are the most common cause of erectile dysfunction among the high blood pressure medicines. The next most common cause is beta blockers. Alpha blockers tend to be less likely to cause this problem. Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen and naproxen) Impotence caused by medicines; Drug-induced erectile dysfunction; Prescription medicines and impotence Burnett AL, Ramasamy R. 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. [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. 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.

• Headache: A common side effect of vasodilators like PDE5 inhibitors.
• Flushing: Redness and warmth of the face and upper body due to vasodilation.
• Dyspepsia: Indigestion or upset stomach, common with sildenafil.
• Nasal congestion: A stuffy or runny nose due to vasodilation in sinuses.
• Myalgia: Muscle aches, a side effect more commonly associated with tadalafil.
• Back pain: A side effect more commonly associated with tadalafil.
• Visual changes: A blue tinge (cyanopsia) or increased light sensitivity.
• Dizziness: Can occur due to a drop in blood pressure.
• Penile pain: Common with alprostadil injections and suppositories.
• Urethral burning: A common side effect of the MUSE suppository system.

[4] Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels. The use of sildenafil and an α1 blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart.

How do health care professionals treat ED?

[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 pills to get her in the mood instantly for people with secondary Raynaud's phenomenon;[9][21] these drugs have moderate efficacy for reducing the frequency and duration of vasospastic episodes.

Also reviewed by David C. Dugdale, MD, Medical Director, Brenda Conaway, Editorial Director, and the A.D.A.M. 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. [32] Sildenafil's brand name, Viagra, is widely recognized in popular culture, and the drug's association with treating erectile dysfunction has led to its recreational use. [33] The reasons behind such use include the belief that the drug increases libido, improves sexual performance,[33] or permanently increases penis size. [34] Studies on the effects of sildenafil when used recreationally are limited, but suggest it has little effect when used by those who do not have erectile dysfunction.

• The discovery of nitric oxide: Its role in erectile physiology won a Nobel Prize.
• The accidental discovery of sildenafil: Originally developed for angina pectoris.

• Military and VA care: Specific protocols for treating ED in veterans.
• Global access: Disparities in availability and affordability of ED treatments worldwide.

In one study, a 25 mg dose was shown to cause no significant change in erectile quality, but did reduce the postejaculatory refractory time. [35] This study also noted a significant placebo effect in the control group. Unprescribed recreational use of sildenafil and other PDE5 inhibitors is noted as particularly high among users of illegal drugs.

• The future of generics: Increasing availability and lower costs for older ED medications.
• Biosimilar testosterone: Potential for biologic versions of testosterone therapies.
• Over-the-counter trends: More countries may approve lower-dose PDE5 inhibitors for OTC sale.
• Digital therapeutics: Apps and online programs for psychological ED treatment.

[36] Sildenafil is sometimes used to counteract the effects of other substances, often illicit. [33] Some users mix it with methylenedioxymethamphetamine (MDMA, ecstasy), other stimulants, or opiates in an attempt to compensate for the common side effect of erectile dysfunction, a combination known as "sextasy", "rockin' and rollin'", "hammerheading", or "trail mix".

How should this medicine be used?

[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.

Penile Injections (Prostaglandins)

[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. [33] Mixing it with amyl nitrite, another vasodilator, is particularly dangerous and potentially fatal. The 2007 Ig Nobel Prize in aviation went to Patricia V. Agostino, Santiago A. Plano, and Diego A.
