How long does Sildenafil last?
On average, Sildenafil usually lasts between 2 and 3 hours before its effects start to diminish. Sildenafil can last up to 5 hours or longer depending on your dosage, your body’s metabolism, and other external factors.
Depending on how your body metabolizes it, you may be able to get an erection several times with Sildenafil in your body. Sildenafil probably won’t make you last longer in bed, though. No research has proven definitively that Sildenafil can increase how long you can have sex.
Sildenafil may not work again immediately after you’ve had sex. Normally, you can’t get another erection right after ejaculating because your body isn’t physically prepared for it.
This is known as the refractory period. It may only last a few minutes, but it can last as long as a few hours or days.
Can any factors affect how long it lasts?
Several important factors can influence how long Sildenafil lasts for you:
- Dosage. The amount of Sildenafil you take affects how long it stays in your system. The smallest available dose, 25 milligrams (mg), won’t last as long as the largest available dose, 100 mg. But taking a higher dose isn’t always recommended, as it may not be safe for you.
- Age. As you get older, your metabolism slows down. So Sildenafil may last longer as you age. In general, you may notice Sildenafil works for a longer period when you’re 65 or older.
- Diet and lifestyle. Eating a large meal or a lot of high-fat foods right before you take Sildenafil can keep it from being metabolized quickly or effectively. But this can also make it last longer as it’s metabolized along with your meal. Drinking alcohol or smoking can also decrease blood flow to your penis, making Sildenafil less effective or shorter-lasting.
- Medications. Some medications, especially antibiotics such as erythromycin (Ery-Tab), clarithromycin (Biaxin), and ciprofloxacin (Cipro), can interact with Sildenafil and affect how long it lasts.
- Overall health. Certain existing conditions can affect how long Sildenafil lasts and how well it works for you. Diabetes, nervous system conditions like multiple sclerosis (MS), and heart conditions like atherosclerosis (fat buildup in your blood vessels) can all make Sildenafil less effective and not last as long. Some kidney conditions may make Sildenafil last longer because of the condition’s effect on your metabolism.
- Psychological state. Feeling anxious, nervous, depressed, or stressed can all influence how your body responds to sexual stimulation. If you’re not relaxed or comfortable during sex, or if you have performance anxiety because of past sexual experiences, Sildenafil may not last long or be fully effective.
How long does it take to leave my system?
Sildenafil usually leaves your system after 2 to 3 hours. Depending on your metabolism, Sildenafil can take 5 to 6 hours to fully leave your system.
A higher dosage will take longer to leave your body. A 25-mg dose may wear off after a couple of hours, but a 100-mg dose may take nearly four times as long to leave your system.
Is there anything I should be concerned about?
Sildenafil often lasts for a few hours. You won’t normally have an erection the entire time, as Sildenafil is only used to help increase blood flow. If you don’t think Sildenafil is working fast enough, try masturbation or foreplay to help stimulate arousal.
If Sildenafil doesn’t work after 30 minutes, don’t take any more than the daily dose that your doctor prescribed. Never take more than 100 mg of Sildenafil in a 24-hour period.
Taking too much Sildenafil can cause priapism, a painful erection that lasts longer than 4 hours. This can damage penis tissue because blood stored in the penis isn’t receiving any oxygen. Get emergency treatment right away if this happens.
When to see your doctor?
Talk to your doctor before you take Sildenafil or any related medication for ED. It’s important to take a safe dose and work out a clear understanding of how much you should take in a 24-hour period.
Some medications for heart conditions, such as nitroglycerin and other nitrates, can interact dangerously with Sildenafil and cause your blood pressure to drop too low.
If Sildenafil isn’t working or isn’t safe for you, talk to your doctor about other possible treatments for ED, such as:
therapy for anxiety, depression, or other similar conditions
