By taking multiple tablets of Revatio or its generic form for ED, it’s possible to approximate the doses of Viagra. But you should only do this if it’s what a healthcare provider prescribes. What Viagra Dosage Is Best For You? Finding the perfect Viagra dose can be a matter of trial and error. Your healthcare provider might adjust your Viagra dosage by weight, age, or other factors.
Can Increasing the Dosage Improve Effectiveness?
It’s necessary to consider all of these factors holistically. For example, the optimal Viagra dosage for 70-year-old men with no underlying health problems could be lower than the optimal Viagra dosage for 50-year-old men with health conditions like diabetes. Determining proper dosage depends on all these factors collectively. Additionally, erectile dysfunction can vary in severity, which sildenafil 130mg can also influence the Viagra dosage prescribed. Currently, 25mg is the lowest dose of Viagra approved by the FDA to treat ED. It’s usually recommended to take it about 30 minutes to an hour before you plan to engage in sexual activity. We cover this topic in more detail in our guide to how long Viagra and other ED medications last.

However, older people or those who have kidney or liver issues might start at a lower dose Although your healthcare provider will provide the ultimate answer, we can address some general questions about this FDA-approved medication like how it works, typical dosages, and factors that influence optimal dosage. Viagra is a medication for treating erectile dysfunction famously called “the little blue pill.” The active ingredient in Viagra is called sildenafil citrate. It’s available as a brand-name drug under the name Viagra and as a generic medication called sildenafil, which is usually available at a white sildenafil tablets much lower cost per tablet.
Interaction with Food and Other Medications
Viagra is part of a class of drugs called phosphodiesterase type 5 or PDE5 inhibitors. In essence, they work by relaxing the blood vessels in your penis to improve blood flow. Erections are all about healthy blood flow. When you’re aroused, your nervous system sends signals to relax the blood vessels that supply the penis. This causes the corpora cavernosa (the erectile tissues inside your penis) to expand as blood flows in. There’s evidence that after taking Viagra, older men will have higher amounts of it in their blood. Because of this, it’s important to listen carefully to your healthcare provider and closely follow their instructions. While there's a well-established link between ED and obesity, Viagra efficacy doesn’t appear to be affected by your weight.

However, taking Viagra with a large, high-fat meal may slow down the absorption of this medication, meaning it could take a little longer before you start feeling its effects. Viagra is safe and effective for most men with ED. But like all medications, it can cause side effects. Our guide to Viagra side effects goes into more detail about various adverse effects and drug interactions that you should be aware of when using either brand-name Viagra or generic sildenafil. Taking an excessive dose of Viagra may result in a sudden drop in blood pressure, which could cause fainting. It’s important to make sure you don’t take more than the amount prescribed by your healthcare provider.
7.2 Alpha-blockers
Research does suggest that taking Viagra at a prescribed dose of 100mg is more likely to treat ED than other doses. In clinical trials, 82 percent of men who used a 100mg dose reported improvements in their erections. However, people who take Viagra at a dose of 100mg are also more likely to experience side effects than those who take lower doses. In particular, taking Viagra at this dose increases the risk of certain vision-related side effects, such as blurred vision, altered color vision, and increased sensitivity to light. It also seems to raise the prevalence of common side effects with clinical trials reporting the following in at least 4% of people: You should never exceed a 100mg dose of Viagra.
Typical dosages
It’s also important not to take Viagra more than once a day, and unless your healthcare provider specifically instructs you to, you should not take more than one dose of Viagra within a 24-hour period. Make sure to alert your healthcare provider if you still find it difficult to get or maintain an erection after using 100mg of Viagra. Following the medical advice of a healthcare professional is the best way to find a Viagra dosage to improve your erections and prevent sexual dysfunction with minimal side effects. If you have ED, your healthcare provider will determine a recommended dosage of Viagra after taking several factors into account, including: Whether you failed to respond to previous dosages Whether you failed to respond to previous dosages Your age, medical history, and overall health Your age, medical history, and overall health It may take a few months to “dial in” your dosage of Viagra.
