Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.
Speak with your healthcare provider about a different dose
If Viagra isn't working for you, you might need a higher dose. But don't experiment on your own: Always speak with a healthcare provider about dosage changes and never take more than one dose of Viagra in any 24 hour period.
Viagra is only recommended to be taken once per day. This means that if you're planning on engaging in sexual activity more than once throughout the day, you shouldn't take a pill every time. And if you take a pill and it doesn't work for you — don't double up and take another one.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained.
If it doesn't work, consider talking to your doctor about switching to a higher dose. Often, Viagra will become more effective after a few tries as you become more comfortable with the medication and confident in its effects.
Viagra doesn't start working immediately after taking it, as the medication needs time to be absorbed into your blood. For most men, it takes around 30 minutes before you start to feel the effects of Viagra. 12 minutes after – One study has shown that some men got an erection just 12 minutes after taking Viagra.
Viagra 100mg is the most effective dosage, but it also has the greatest risk of side effects. You may want to try Viagra 100mg if the standard 50mg dose didn't work well enough for you, but you didn't get any serious side effects.
Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues.
Viagra may not work fully the first time, especially if you feel anxious about sex. There are drug interactions linked to Viagra. Viagra can cause side effects, most of which are mild and temporary. All ED medications work best when they're combined with a healthy lifestyle.
When used in women, Viagra is thought to raise blood flow to the genitals so that there's more sensitivity and stimulation. Studies have shown that Viagra may provide a benefit for women having difficulty with sexual arousal — since it may help them respond better to sexual stimulation.
Viagra is a useful form of treatment for erectile dysfunction. It is best to take the drug around 60 minutes before sexual activity, and its effects can last up to 4 hours. Viagra cannot cause an erection if there is a lack of sexual arousal.
What happens when a woman takes Viagra? Even though Viagra doesn't necessarily increase a woman's sexual pleasure, a 2014 study indicated that the medication increases blood flow to a woman's genitals. This leads to swelling of the clitoris and increased lubrication of the labia, both signs of physical arousal.
Viagra does not make your penis bigger. No pill does. It can help you get and maintain a firmer erection that lasts longer, though. To put it another way, sildenafil and other ED medications make the most of what you've got.
When you have trouble achieving or maintaining an erection with a partner, it can be embarrassing – especially if it is happening for the first time. When something like this happens, it is easy to close yourself off and wallow in your worry and self-pity.
Causes of erectile dysfunction
Blood flow into the penis is reduced or the nerves are damaged. Emotional and psychological reasons such as stress, low self-esteem or performance anxiety. Lifestyle changes such as drinking more alcohol, new medication or taking recreational drugs.
The biggest difference between Viagra and Cialis is the amount of time their effects last. Viagra remains effective for 4 to 6 hours, which offers ample opportunity to have sex on multiple occasions if you wish. However Cialis typically allows you to achieve erections for up to 36 hours after taking a tablet.
Viagra does not stimulate you sexually, it can only help you get an erection once you're already aroused. Because Viagra only helps you to get an erection by improving blood flow to the penis, it doesn't force you to get an erection, so it won't work unless you're sexually stimulated.
Viagra can cause some serious side effects. 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.
As discussed above, alcohol can potentially cause or worsen ED. So, if you're taking a medication like Viagra to help you get or maintain an erection, alcohol may be counteracting its effects. In other words, it's best to limit alcohol consumption if you're taking an ED medication — or avoid it altogether.
