Viagra (sildenafil) is primarily approved to treat erectile dysfunction (ED), and its "positive side effects" are actually its intended therapeutic effects or benefits, some of which extend to other conditions.
Headaches were the most common side effect reported in clinical trials of Viagra. They happen because Viagra widens your blood vessels. This helps you have an erection, but it can also cause headaches and other side effects.
No significant differences in segmental or total colon transit time were noted; however, significant changes in stool frequency and trends toward decreased stool consistency were noted during sildenafil use. A trend toward reduced resting anal sphincter pressure was seen after sildenafil.
Viagra boosts blood flow to the penis — causing an erection — by turning off an enzyme called phosphodiesterase 5. But in the process, the drug also meddles with a related enzyme in retinal cells. At high doses, experts say, this could permanently damage the retina.
Sildenafil does not directly cause prostate related complications. However, some studies suggest that it may lead to mild side effects such as headaches and facial redness. Most men tolerate its use without significant problems.
Flushing can happen for the first few days after taking Viagra. It might help to avoid alcoholic and caffeinated drinks such as tea and coffee during this time - instead cool yourself down with colder beverages. Speak to your doctor if the hot flushes don't go away.
Sildenafil, a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5), may rarely cause gouty arthritis. Gout can either manifest as acute arthritis or chronic arthropathy, which is also called tophaceous gout.
Spinal cord center for reflex erections: The parts of the spinal cord labeled S-2 to S-4 (see image) impact this type of erection. Some facts: If this center is intact, impulses from penis stimulation may cause an erection. If your injury is above S2, you may be able to have this kind of erection.
Sildenafil enhances the relaxation of urogenital smooth muscle in the corpus cavernosum during sexual stimulation via modulating the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) cascade [10].
Key takeaways: Medications like Viagra (sildenafil) are FDA approved to treat erectile dysfunction (ED). But some people take Viagra off-label to enhance sexual performance, or improve other sexual problems, even when they don't have ED. Taking non-prescription Viagra, or using it recreationally, can be dangerous.
“These medications, such as Cialis and Viagra, are believed to offer cardiovascular benefits through improved blood flow, lowering blood pressure, enhancing endothelial function, and providing anti-inflammatory effects,” said Dr.
Can Viagra Help Reduce Alzheimer's Risk? Because of evidence that tau levels may be reduced in people who take Viagra and the benefits it has on brain blood vessel health in general, it's possible the drug may become an Alzheimer's risk reducer. But doctors aren't recommending it for that use just yet.
Symptoms
Daily dosing with sildenafil may improve lower urinary tract symptoms. However, the lack of effect on urinary flow rates may mean that a new basic pathophysiology paradigm is needed to explain the etiology of lower urinary tract symptoms.
The most common Viagra side effects are headache, flushing, and upset stomach. These effects are usually mild and often resolve on their own. Viagra can cause an erection that lasts longer than 4 hours (called priapism), but this is rare. This can result in permanent damage if left untreated.
The present study indicates that sildenafil induces retinal vasodilation and increases retinal blood flow in vivo. After single dose administration of 100 mg sildenafil to healthy volunteers we observed a 4.7% increase in retinal venous diameters and a 15.7% increase in retinal blood flow.
1 Oils such as rose, lavender, and cinnamon are believed to promote emotional balance, reduce anxiety, and improve circulation, potentially boosting erectile function.
Water and other low-calorie drinks make good alternatives to alcoholic or sugar-laden concoctions. Some research suggests that some juices (like grape and pomegranate juice) may help support erectile health, thanks to compounds called polyphenols.
Exercise regularly.
Cardio and strength training improve circulation throughout the body, including the penis. Better blood flow means stronger erectile response and more nerve stimulation during sex.
