Just popped your first dose of Viagra and wonder when you should expect it to "kick in"? You're definitely not the only one who asks; it's probably the question everyone has the first time they take it. For the most part, the answer is an hour or less; however, there are a few things that affect just how fast sildenafil starts to work, which is good to know to time it properly: How Viagra actually works. The active compound in Viagra, sildenafil, is known as a PDE5 inhibitor.
The pill alone will not provide an erection or arousal. Check how an erection works for more clarity.
How Long Does It Take to Show Effects?
Generally, the effects of sildenafil will begin to become significant 30-60 minutes after taking the tablet orally, though some people report benefits as soon as 20-30 minutes, and some may have to wait closer to an hour, or a bit longer, for results. The peak concentration of the drug is usually at 1 hour, when the benefit may be the most pronounced. For this reason, taking a tablet for potential sex an hour earlier than planned is preferable to taking it immediately beforehand.
Key points:
- Onset: Usually within 30–60 minutes.
- Peak: Around 1 hour.
- Food: Fatty meals may delay absorption.
- Stimulation: Sexual arousal is still required.
- Timing: Take it about 1 hour beforehand.
- Response: Timing varies between individuals.
How Long Does It Last?
Once it kicks in, the typical effects of Viagra will continue for 4 hours for the majority of men, though it may be that mild effects are still present for longer. It is not the case that you will have an erection for the entire period; however, it just means that should the user become aroused with intent during this period, they will continue to be able to achieve one;
What Can Slow Viagra's Response Time?
Food and timing of meals
This is the largest factor. Consuming Viagra with a heavy meal, and particularly a high-fat meal, can decrease the stomach's absorption of Viagra, potentially leading to the time of onset extending beyond an hour or two. Consumption on an empty stomach or a light meal is likely to produce the fastest, most consistent result. Check Worst Foods for Erectile Dysfunction.
Alcohol
The use of alcohol shortly before taking Viagra can similarly blunt or delay the medication's response. Excessive alcohol consumption in general can contribute to erection difficulties independent of medication.
Dose Amount
Common dosage levels for Viagra include 25 mg, 50 mg, and 100 mg; while larger dosage amounts will not inherently affect the response time significantly, taking an amount that is too small for an individual can result in a weaker or subtler response over time.
Your Age, Metabolism and Organ Function
Age and kidney or liver function can affect the working of sildenafil (how sildenafil is cleared from the body), not how quickly it is absorbed. Older age and moderate to severe hepatic impairment or severe renal impairment can reduce the rate at which sildenafil is eliminated from the bloodstream, increasing the drug's overall exposure in the system rather than simply delaying when it starts to work. Severe hepatic impairment is considered a contraindication to sildenafil use, and it should not be taken by patients with this condition. Pharmacokinetic studies show these factors affect circulating levels of sildenafil, and, under medical supervision, clinicians may consider a lower starting dose such as 25 mg for patients with mild-to-moderate hepatic impairment or severe renal impairment. Mild to moderate kidney impairment does not routinely require the same dose adjustment. It is advised to always follow your own doctor's specific dosing advice rather than adjusting your dose yourself.
Other drugs
Sildenafil must never be combined with nitrate medicines (such as glyceryl trinitrate) or with riociguat, a medicine used to treat pulmonary hypertension — taking either alongside sildenafil can cause a dangerous, potentially life-threatening drop in blood pressure. Other blood pressure medicines, including alpha-blockers, can also interact with sildenafil to cause excessive drops in blood pressure and other adverse effects — this is a safety concern, not simply a change in onset time. Do not combine sildenafil with other PDE5 inhibitors (such as tadalafil or vardenafil), or with any other erectile dysfunction medicine, without your doctor's specific direction.
If an erection lasts longer than four hours (priapism), this is a medical emergency. Seek urgent medical attention immediately, as delayed treatment can cause permanent damage.
Anxiety or stress
Sexual performance anxiety alone can affect how well Viagra works. Sildenafil supports the mechanical process and blood flow.
Getting The Timing Right: Tips
It's best to take this medication either on an empty stomach, or at the least following a light snack, rather than straight after a large or fatty meal. You should ensure there is a 60-minute buffer between taking this medication and sexual intercourse.
You should not be drinking in large quantities around this time. Never take more than one dose of Viagra in a twenty-four-hour period. Don't be discouraged if, on your first attempt, it appears not to work, as response times vary slightly between individuals, and may require several attempts before you get a sense of how this medication works for you.
What If Viagra Doesn't Seem To Be Working?
If after a period of time and all factors considered correctly (i.e. not on a large meal, having adequate sexual stimulation, not having any underlying chronic illness, etc.) you still believe that Viagra does not appear to be working for you, then you should have this discussed with your G.P.
Your GP will perhaps have to review your dosage, or try an alternative medication that inhibits PDE5, which may work better for you, or investigate any chronic illnesses (e.g. Heart disease, diabetes, or low testosterone, etc.) that may be related.
FAQs: How Long Does It Take For Viagra To Work:
How fast is Viagra supposed to work?
Most users experience the beneficial effects within a matter of 30 to 60 minutes from when it is administered, but results vary from patient to patient. The drug does not necessarily induce a penile erection automatically; sexual stimulation is still necessary. It has been known that Viagra or sildenafil may have slower absorption when taken after an excessively rich or greasy meal, thus making sildenafil have a more variable duration of action and/or effect.
Is sildenafil absorbed faster on an empty stomach?
Often yes, the effect of sildenafil can occur much quicker on an empty stomach, or after having a relatively "light" meal. However, an overly rich, high-fat meal will usually cause slower absorption rates, and therefore the onset of medication may have to wait a longer amount of time to reach its peak concentration. Having medicine with food, however, doesn't strictly guarantee it won't have a desired effect.
Does Viagra have an effect without sexual stimulation?
No, the effects do not directly initiate an erection and, even though Viagra contains drugs which, when taken during sexual arousal, cause increased blood flow to the penis, making it possible to get and keep an erection, ingestion of sildenafil without taking any stimulating steps will normally bring about no penile tumescence.
Can Viagra be used every day?
Viagra is used as needed, no more than once daily for ED. Using viagra on consecutive days may be appropriate when prescribed by your doctor. An alternative PDE5 drug, tadalafil, comes as a low-dose pill for daily consumption.
Is it normal to feel that the first dose isn’t effective?
Yes, it can happen. Sildenafil can seem less effective if it has been taken at the wrong time, after a heavy meal, at the wrong dose, or without the necessary sexual arousal. Anxiety and other psychological or physiological factors can also interfere with erectile function.
What if sildenafil does not work consistently?
If sildenafil does not work consistently, consult a physician rather than increasing the dose on your own. Your doctor can assess how you are using the drug, review other medications and health conditions, and decide if you should take a different dose or treatment instead.
