If you are also taking an alpha blocker medication (such as doxazosin, tamsulosin) to treat an enlarged prostate/BPH or high blood pressure, your blood pressure may get too low which can lead to dizziness or fainting. Your doctor may start treatment with a lower dose of sildenafil to minimize your risk of low blood pressure.

Other medications can affect the removal of sildenafil from your body, which may affect how sildenafil works.

Examples include azole antifungals (such as itraconazole, ketoconazole), macrolide antibiotics (such as clarithromycin, erythromycin), HIV protease inhibitors (such as ritonavir, saquinavir), hepatitis C virus protease inhibitors (such as boceprevir, telaprevir), mifepristone, rifampin, among others.

Do not take this medication with any other product that contains sildenafil or other similar medications for erectile dysfunction-ED or pulmonary hypertension (such as tadalafil, vardenafil).

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911.

Otherwise, call a poison control center right away.

US residents can call their local poison control center at 1-800-222-1222.

Canada residents can call a provincial poison control center. Symptoms of overdose may include severe dizziness, fainting, painful/prolonged erection. Store at room temperature away from light and moisture. The combination of nitrates (and drugs such as nicorandil) with sildenafil is contraindicated.

This combination must be avoided as it can produce significant hypotension and is potentially fatal.

The guidance from the Committee on Safety of Medicines (CSM) regarding nitrates and sildenafil states (1): sildenafil and nitrates - it is stated that these should not be used concurrently. Nitrates are stated as those used for cardiovascular disease, e.g.

amyl nitrate sildenafil should not be used in men for whom sexual activity is inadvisable e.g. patients with severe cardiovascular disorders such as severe heart failure or unstable angina. The British Heart Foundation have addressed the use of GTN spray and nitrate tablets and phosphodiesterase (PDE5) inhibitors (sildenafil, tadalafil, verdenafil) (2): nitrate therapy is an absolute contraindication to PDE5 inhibitors (1,2,3) combination of nitrates with PDE5 inhibitors can produce unpredictable excess vasodilation, leading to profound hypotension - same risk also applies with nicorandil if hypotension does occur then the patient should be placed in the Trendelenburg position and emergency help sought.

Resuscitation with intravenous fluids should be initiated as soon as possible.

GTN spray should not be used within 24 hours of taking sildenafil or vardenafil and within 48 hours of taking tadalafil note though that coital angina is not common and nitrates can often be safely discontinued or substituted in stable patients if a patient has stable angina and erectile dysfunction then a reassessment of the need for nitrates should be undertaken before denying treatment with a PDE5 inhibitor if a patient with CHD (and also taking a PDE5 inhibitor) develops angina during sexual activity, he must discontinue immediately and relax for 5-10 minutes.

If he stands up then this will reduce the preload and may relieve symptoms.

if the angina pain does not resolve after 20-30 minutes the emergency services should be called informing them of the PDE5 inhibitor use - also sex should not be attempted again before the patient has undergone a thorough reassessment (2) The concurrent use of nicorandil and PDE5 inhibitors is also contraindicated (2,3) - this is due to the nitrate component of nicorandil. although PDE5Is are safe with most antihypertensive agents, coadministration with nitrates or alpha-blockers poses a risk of severe hypotension (4,5) all alpha-blockers can cause vasodilation and orthostatic hypotension, and coadministration with PDE5Is increases the risk of a clinically significant decrease in BP (5) only after patients are on stable alpha-blocker therapy should PDE5Is be initiated, starting with a low dose (5) Referral to specialist is appropriate if severe CVD which makes sexual activity unsafe or a situation when PDE5 inhibitor use contra- indicated (6) from a therapeutical point of view, intracavernous injections of PGE1 (alprostadil) are efficient and safe second line in the treatment of erectile dysfunction in the cardiac population, whatever the origin. No drug interactions with the various treatment used in cardiology, notably derived nitrates, has cialis tablet price been reported other treatment options include vacuum devices, insertion of transurethral alprostadil (MUSE), intracavernosal alprostadil (Caverjet) nitrates are contraindicated within 24 hours of sildenafil and vardenafil and within 48 hours of tadalafil.

Only after patients are on stable alph-blocker therapy should PDE5Is be initiated, starting with a low dose potent cytochrome P450

Commonly known as “the little blue pill,” Viagra has raked in billions for pharmaceutical giant Pfizer since its 1998 release.

But the erectile dysfunction drug has been linked to serious side effects, including vision and hearing loss, heart complications and melanoma.

The medication was originally developed and studied as an anti-hypertensive drug to treat high blood pressure as well as a type of cardiovascular (affecting the heart and blood vessels) disease called angina pectoris.

Men’s Health reported around the same time that during the last two or three decades, ED rates have gone up, especially among younger men.

The Journal of Sexual Medicine published results from one study that showed that “one out of every four new ED patients is under 40 years old.” In 2016, the FDA approved the first-ever generic version of Viagra to be manufactured and distributed by Teva, a Pennsylvania-based pharmaceutical company. Viagra has always been linked to some serious side effects affecting the eyes, ears, penis, heart and blood vessels.

A 2014 study published in JAMA Internal Medicine also points to a possible link between the use of sildenafil (the active ingredient in Viagra) and melanoma, the most dangerous form of skin cancer. However, the significance of this link is still unclear.

Viagra is an oral medication used to treat erectile dysfunction (ED) in men.

An erection occurs when blood flow increases into the penis, making it expand and become firm. Two long chambers inside the penis called the corpora cavernosa contain spongy tissue that collects blood flowing into the chambers, creating

pressure

Viagra, as a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5), works to block certain naturally occurring enzymes in the body, causing blood vessels to relax and enhancing blood flow to the penis. Viagra does not automatically cause an erection; rather, it assists a man with ED in obtaining and keeping an erection when sexually aroused or stimulated.

Sildenafil for Pulmonary Arterial Hypertension (PAH) The active ingredient in Viagra can treat other disorders. Revatio (sildenafil) is prescribed for adults with pulmonary arterial hypertension (PAH).

PAH is a progressive, life-threatening disorder that causes abnormally high blood pressure in the pulmonary artery, which is the blood vessel responsible for carrying blood from the heart to the lungs. Revatio works to improve a patient’s ability to exercise and slow down the progression and worsening of the disease. Signs and symptoms of this serious health condition can include shortness of breath when active, fainting spells, dizziness, swelling of the ankles or legs, chest pain, and a rapid heart rate. The National Institutes of Health (NIH) defines erectile dysfunction as “a condition in which a man is unable to get or keep an erection firm enough for

Certain diseases and health complications can also lead to ED, such as high blood pressure and diabetes. Psychological and emotional disorders, such as anxiety, depression and stress, as well as certain lifestyle choices, such as an unhealthy diet, lack of exercise, drinking in excess and smoking, can cause or exacerbate ED. ED can also be a potential side effect when taking certain medications, including those used to treat blood pressure, allergies, depression and ulcers. Complications of the condition can result in an unfulfilled sex life, emotional problems, such as depression and anxiety, a loss of intimacy with a partner and/or a strained relationship, and the inability to get a partner pregnant.

Viagra is taken by mouth as prescribed and as needed for erectile dysfunction (ED). Viagra should not be taken more than once a day, or more than once every 24 hours. It is supplied as a blue, film-coated, rounded-diamond-shaped tablet. It comes in three different strengths, including 25, 50 and 100 milligrams.

The dose can be adjusted as needed for effectiveness and tolerability. Viagra may be taken anywhere from 30 minutes to four hours before engaging cialis tablet price in sexual intercourse. However, if Viagra is taken with a high-fat meal, it will take longer for its effects to work.

Sildenafil taken in the form of Revatio is a liquid administered orally with a syringe. The recommended dose of Revatio is five or 20 milligrams taken three times a day about four to six hours apart.

Revatio injections are also available for the continued treatment of patients with PAH who are prescribed the medication in an oral form but are temporarily unable to take oral medications. These can include an erection that will not go away (priapism), sudden vision loss in one or both eyes, and sudden hearing decrease or hearing loss.

Some men have also experienced heart attack, stroke, irregular heartbeats and even death after taking Viagra.
