Viagra, also known as sildenafil, is a medication used to treat erectile dysfunction (ED), a common condition that affects over 150 million men worldwide. ED is characterized by the inability to achieve or maintain an erection during sexual activity.
Viagra works by blocking the activity of an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down certain messengers involved in the process of achieving an erection. By blocking the activity of PDE5, Viagra helps to relax the muscles and blood vessels in the penis, allowing for an increase in blood flow and achieving an erection.
Viagra Dosage
Viagra comes in tablet form and is available in 25 mg, 50 mg, and 100 mg doses. It is usually taken orally, about an hour before sexual activity, but can be taken anywhere from 30 minutes to 4 hours before sexual activity. It is important to note that Viagra only works when you are sexually aroused and that it should be swallowed whole and not crushed or chewed.
Effects Of Viagra
The effects of Viagra can last for up to 4 to 8 hours, depending on the person and the dose taken. Some people may experience more than one erection during this time, however, it’s worth noting that an erection lasting longer than 4 hours can be a condition known as priapism which can cause permanent damage to the tissue that helps you become erect.
It’s important to be aware of the potential side effects of Viagra. These can include headaches, flushing, indigestion, and visual disturbances, but these are usually mild and temporary. More serious side effects such as chest pain, irregular heartbeat, and sudden vision loss should be reported to a healthcare provider right away.
Over The Counter Medications
Viagra should not be used by people who are taking certain medications, such as nitrates, or by those with certain health conditions, such as severe heart or liver problems. It’s also important to inform your healthcare provider of any other medications you are taking, including herbal supplements and over-the-counter medications, as they may interact with Viagra.
It’s also worth noting that Viagra should not be used by people who do not have ED. It is a prescription medication and its use should be directed by a healthcare provider. It’s also important to keep in mind that Viagra is not a cure for ED and that it does not increase sexual desire or libido.
About Viagra
In addition, people who have sickle cell anemia, multiple myeloma, leukemia, or certain penile deformities (like Peyronie’s disease) are more likely to have a prolonged erection. Therefore, these individuals need to consult with a healthcare provider before taking Viagra, or any other PDE5 inhibitors.
In summary, Viagra is a medication used to treat erectile dysfunction (ED) by blocking the activity of an enzyme called PDE5. It helps to relax the muscles and blood vessels in the penis, allowing for an increase in blood flow and achieving an erection.
Follow Safe, Recommended Doses
The standard recommended dose of Viagra for treating ED is 50 mg, but your doctor could prescribe anywhere from 25 mg to 100 mg.
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. Exceeding the recommended Viagra dosage can put you at risk for serious effects.
Because Viagra can affect other parts of the body, such as the heart and lungs. It’s important to stick to the dose and instructions your doctor provides. And if your prescribed dose isn’t working for you, they may make adjustments to find one that works.
Take It On An Empty Stomach
Although it can be taken with or without food, Viagra tends to work best when taken on an empty stomach. So, to maximize its effects, try to take it separately from meals.
But if you do end up eating beforehand, avoid taking it with a high-fat meal since this can affect how quickly the medication is absorbed and how fast it kicks in.

Does Viagra Make You Last Longer?
Just as there are several reasons why someone experiences erectile dysfunction, the same goes for premature ejaculation. And while medications like Viagra can help your erection stay firm, it usually isn’t the first choice for preventing ejaculation.
However, the two issues often happen together, so your provider may recommend Viagra to help with any underlying erectile dysfunction. As a result of treatment, you may see some improvement in how long you last.
But if not, your provider may have you try behavioral methods (e.g., practicing ejaculation control), counseling, or other medications like numbing creams or antidepressants to help.
