While Viagra (sildenafil) isn't a direct cause of mini-strokes (TIAs) in most healthy individuals, reports exist of strokes and TIAs occurring after use, often linked to a sudden drop in blood pressure, especially when combined with nitrates or in those with pre-existing heart/blood vessel conditions. The drug can lower blood pressure and affect cerebral blood flow, posing risks for vulnerable patients, though some research even suggests potential benefits for brain blood flow in certain conditions.
Several studies examining the effects of sildenafil on mortality have been published during recent years. The great majority of these studies found that sildenafil is not an extra risk factor for an acute coronary syndrome or sudden cardiac death.
Yes, but it's recommended to start with a lower dose. The typical starting dosage of Viagra is one 50 mg tablet about an hour before sexual activity. But for adults over age 65, it's recommended to start with a lower 25 mg dose. Compared to younger people, Viagra leaves the body more slowly in older adults.
“Mechanistically, Viagra targets Alzheimer's biology for a neuroprotective effect,” says Dr. Cheng. Improved blood flow triggered by Viagra also improves overall brain function and reduces inflammation, factors that can help guard against the sort of neural brain decline associated with Alzheimer's.
There have been reports of heart attack, stroke, irregular heartbeat, bleeding in the brain or lungs, high blood pressure, and sudden death in men who took sildenafil for erectile dysfunction. Most, but not all, of these people had heart problems before taking sildenafil.
There isn't good evidence that Viagra is dangerous for a person who had a stroke. One trial suggested there was benefit of reducing the size of a stroke with Viagra. However, Viagra does lower blood pressure by a few points, so if your husband's blood pressure is on the borderline, that might be an issue.
The vasodilating action of sildenafil affects both the arteries and the veins, so the most frequent side effects of sildenafil are headache and facial flushing. Sildenafil causes small decreases in systolic and diastolic blood pressures, but clinically significant hypotension is rare.
In summer 2024, UK-based research published in Circulation Research showed that Viagra can get into the blood vessels of your brain, improving blood flow to the area and improving blood vessel function in those at a higher risk of vascular dementia.
Both Viagra and the non-branded generic version, Sildenafil, are safe to take everyday, both in their 50mg and 100mg dosages. However, you really shouldn't be taking them daily if you are not intending to engage in sexual activity daily. Importantly, you shouldn't take Sildenafil or Viagra more than once a day.
Phosphodiesterase-5 inhibitors (PDE5-I) are commonly used for on-demand or chronic treatment of ED. It is widely known that PDE5-I have lower response rates in older men than in younger patients, but they have the advantages of ease of use and excellent safety profile, also in the elderly.
What alternative medications to Viagra are there?
Can you cut Viagra in half? Viagra tablets can sometimes be split, but it's not always recommended. While splitting may seem like a way to adjust your dose or save money, it can lead to inaccurate dosing if not done carefully.
However, this new study says Viagra actually causes platelet clumping. It does that by elevating levels of a compound in cells called cyclic guanosine monophosphate (cGMP). This compound actually encourages platelets to clump. The researchers used laboratory cells and mouse and human platelets in their research.
chest pain – a feeling of pressure, heaviness, tightness or squeezing across your chest. pain in other parts of the body – it can feel as if the pain is spreading from your chest to your arms (usually the left arm, but it can affect both arms), jaw, neck, back and tummy. feeling lightheaded or dizzy.
Use of illegal and highly addictive substances, including cocaine, heroin and amphetamines, have been associated with an increased risk of stroke. These substances can speed up the heartbeat and raise blood pressure, causing damage to the blood vessels in the brain, ultimately leading to a stroke.
have a serious heart or liver problem. have recently had a stroke, heart attack or a heart problem – your doctor should carefully check whether your heart can take the additional strain of having sex. have low blood pressure (hypotension) have a rare inherited eye disease, such as retinitis pigmentosa.
The study found that people had a higher risk for dementia if they took:
The 10 warning signs of dementia include memory loss, difficulty with familiar tasks, confusion about time/place, trouble with language, poor judgment, misplacing things, personality changes, loss of initiative, and problems with visual/spatial skills, requiring professional assessment to distinguish from normal aging.
The most common side effects are headaches, feeling sick, indigestion and dizziness. Many people have no side effects or only mild ones. It can be dangerous to take sildenafil if you also take medicines called nitrates (often given for chest pain). The combination can cause a dangerous fall in your blood pressure.
Overall, the most common adverse effects of sildenafil are strongly associated with its pharmacological nature as an inhibitor of PDE5 (headache, nasal congestion, ageing and dyspepsia) and as a weak inhibitor of PDE6 (visual impairment), being dose-dependent and observed in 6–18% of men taking sildenafil [53].
Both drugs have a relatively mild risk profile. It is worth noting that any side effects experienced from tadalafil will typically last longer because the drug remains in the bloodstream significantly longer than sildenafil.
Sildenafil citrate (Viagra®; Pfeizer US Pharmaceutical Group, New York, NY, USA) is a potent vasodilating agent to treat male erectile dysfunction. Among its adverse effects, hemorrhagic stroke has not been widely reported yet.
High blood pressure is the leading risk factor for stroke and a number of heart conditions. Without treatment, high blood pressure can advance and affect other systems.
The most common sexual problems that have been identified after stroke include decline in libido and coital frequency, decline in vaginal lubrication and orgasm in women, and poor or failed erection and ejaculation in men. The observed decline in sexual functions appears to be multifactorial in nature.
