If you and your doctor determine that Viagra is safe and effective for you, you’ll likely take it long term. The following information describes commonly recommended dosages for ED. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs. This article describes typical dosages for Viagra provided by the drug’s manufacturer.

Avoid consumption of alcohol as it may impair your ability to get an erection. Taking SILDENAFIL after a heavy meal might take longer time for the medicine to work; therefore you are advised to take SILDENAFIL with light meals. Viagra 100 mg Tablet belongs to the group of medicines called phosphodiesterase type-5 (PDE 5) inhibitors primarily used to treat erectile dysfunction (impotence) in adult men. Additionally, Viagra 100 mg Tablet may also be used to treat pulmonary arterial hypertension (high blood pressure in the lungs) in adults to improve the ability to exercise and to slow down clinical worsening. Viagra 100 mg Tablet works by relaxing the blood vessels in the penis, thereby allowing the blood to flow into the penis when the person is sexually excited. Thus, Viagra 100 mg Tablet helps treat erectile dysfunction.

Peak concentration in the blood is reached after two hours for tadalafil and about one hour for sildenafil. As such, we always suggest taking medication about an hour or two before sexual activity. The time it takes for the drug to function will vary between patients, so use prior experience as a guide.

Both Sildenafil and Viagra can be taken every day, up to the recommended maximum dosage of 100mg. It is a highly effective and minimally disruptive medication that can get to work in less than an hour – and so should help men with erectile dysfunction enjoy more adventure and freedom. The 50mg dose is usually sufficient to make it easier to gain and maintain an erection for 3-6 hours. If you take Sildenafil, it’ll start to work within minutes.

Physicians should consider whether their patients with underlying NAION risk factors could be adversely affected by use of PDE5 inhibitors. Individuals who have already experienced NAION are at increased risk of NAION recurrence. Therefore, PDE5 inhibitors, including VIAGRA, should be used with caution in these patients and only when the anticipated benefits outweigh the risks. VIAGRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines.

We also provide a free online consultation for anyone who requests an ED treatment through us to make sure the treatment is safe for you to take and doesn’t conflict with any medication you’re taking. Each consultation is personally and privately reviewed by a clinician who checks your answers to see if your chosen erectile dysfunction tablets are appropriate for you. Contrary to popular belief, taking Viagra Connect won’t result in an instantaneous erection. Likewise, Viagra Connect does not enhance your libido or sexual desire. It simply allows more blood to enter the penis when you become aroused so you can experience firmer erections that last longer. When shopping online, it is important to only make orders as licensed pharmacies.

For Viagra to work properly, you'll need to be sexually excited. According to Viagra’s FDA level, it has a terminal half-life of roughly 4 hours. This means that Viagra stays in the system for roughly 4 hours post-dose.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine. This medicine usually begins to work for erectile dysfunction within 30 minutes after taking it. It continues to work for up to 4 hours, although its action is usually less after 2 hours. For sildenafil to work properly, you'll need to be sexually excited.

When your brain sends pyschosexual signals down your spinal cord, this encourages an erection. The penis retains the increased blood within it and stays temporarily stiff. Sildenafil acts on the enzymes responsible for muscle contraction within the blood vessels; allowing better blood flow to – and within – the penis.

However, eating food, particularly high-fat food, can reduce the effectiveness of Viagra. Talk with your healthcare provider about your sex life and desired use. Both medications are generic now and can be found at discounted rates, making them more accessible than ever before. PDE5 inhibitors may be used to treat other conditions besides PAH.

Some men will experience unwanted side effects even on the median dose of Viagra. This sort of problem can sometimes be resolved by moving to the lower dose. Your doctor will discuss making this change with you; you shouldn’t try to split pills. "In between" doses aren’t licensed for the treatment of ED in the US. For example, Sildenafil 40mg is not used to treat erectile dysfunction. The Sildenafil 25mg dose can be a good starting point for men over the age of 65 with other medical conditions.

Taking SILDENAFIL with medicines used to treat angina/chest pain such as nitrates/nitroglycerin may cause severe lowering of blood pressure. Consult your doctor if you have a history of heart attack/stroke.

Less common side effects may include nausea, dizziness, rash, increased urination, and diarrhea. In rare cases, Generic Viagra may cause an erection that lasts longer than 4 hours. Other rare side effects may include an irregular heartbeat, chest pain, and sudden vision loss. Viagra contains the active ingredient sildenafil which is available as a generic Cialis medication. Often called the little blue pill, it works by improving blood flow to your penis, making it easier to get an erection hard enough for sex. It’s one of the most effective ED treatments available, working for up to 74% of men who take it.

Single doses of antacid (magnesium hydroxide/aluminum hydroxide) did not affect the bioavailability of VIAGRA. Although the interaction between other protease inhibitors and sildenafil has not been studied, their concomitant use is expected to increase sildenafil levels. Cimetidine (800 mg), a nonspecific CYP inhibitor, caused a 56% increase in plasma sildenafil concentrations when co-administered with VIAGRA (50 mg) to healthy volunteers. In addition, N-desmethyl metabolite AUC and Cmax values significantly increased by 200% and 79%, respectively in subjects with severe renal impairment compared to subjects with normal renal function. The mean profiles of the change from baseline in standing systolic blood pressure in subjects treated with doxazosin in combination with 100 mg VIAGRA or matching placebo are shown in Figure 4.

If you have any questions or concerns about your prescription, you should discuss them with your healthcare provider. Sildenafil, the active ingredient in Viagra, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing blood vessels in the penis, allowing increased blood flow during sexual stimulation, which helps achieve and maintain an erection. Whilst Viagra 50mg tends to be the normal Viagra dose to start on, this isn’t the case for everyone.

There is a stereotypical view of men’s sexual urges – that all men want sex all the time. This generalisation can make life especially challenging for the 40% of men who have difficulty getting, and keeping, an erection before they hit 40, and over 50% of men who have some difficulty after 40. If sildenafil tablets are not working, you should continue to take the tablets and use them on 8 separate occasions.

Sildenafil and Viagra both contain the same active ingredient, sildenafil citrate. They also are identical in their efficacy, safety and side effects. Both are available in the same dosages (25mg, 50mg, 100mg). Take one sildenafil tablet around 1 hour before sexual activity. Food can affect the absorption of sildenafil, so for best results, you should take sildenafil tablets on an empty stomach or eat a light meal beforehand.

However, there’s no evidence that Viagra caused these bleeding problems. If Viagra is taken with food, especially with a high fat meal, it will take longer to start working. We anticipate reposting the images once we are able identify and filter out images that do not match the information provided in the drug labels.

Like any new medication, you probably don’t know what to expect. It’s important to understand how to take Viagra correctly to get the best results. Taking too much Viagra at one time, not taking enough, or taking it under the wrong circumstances could potentially cause side effects, or for the drug to not work at all. Cialis can be taken daily, providing constant treatment for ED for people who have sex frequently. Viagra is always taken as needed, usually an hour before having sex.

It is the original erectile dysfunction medication and has helped millions of men around the world. You can order the branded Viagra or a lower cost generic equivalent. Simply answer a health questionnaire and one of our prescribers will make sure this treatment is right for you. You should not take any other erectile dysfunction treatments or tablets alongside Spedra or within 24 hours of taking them. If you find that your Spedra dose is not working effectively for you, you can up it to 200mg, or speak to your doctor to try a different ED medication.

Furthermore, the fact that Sildenafil is an approved ED treatment and used around the globe shouldn’t deter you from reading the accompanying patient information leaflet the first time you use it. Both medications are phosphodiesterase type 5 (PDE5) inhibitors that work by increasing blood flow to the penis. If you experience any of these symptoms, seek immediate medical attention. Viagra is a type of erectile dysfunction (ED) treatment for men that’s taken about 60 minutes before sex.

Two clinical studies were specifically designed to assess the time window after dosing during which sildenafil could produce an erection in response to sexual stimulation. In a separate RigiScan study, sildenafil was still able to produce an erection in response to sexual stimulation 4-5 hours post-dose. Physicians should advise patients to stop use of all PDE5 inhibitors, including VIAGRA, and seek medical attention in the event of a sudden loss of vision in one or both eyes. Physicians should discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye. Sold under the brand name Addyi, Flibanserin claims to increase sexual arousal by altering the chemicals in the brain. In the US, the drug - which started as a treatment for depression - is approved to treat low sexual desire in women before menopause.

Viagra (sildenafil) was the first erectile dysfunction pill the FDA approved, back in 1998. Like Cialis, it’s a PDE5 inhibitor that increases blood flow to the penis.

These side effects can include dizziness, lightheadedness, or even fainting. For more information about using Viagra with alpha-blockers, see the "Viagra interactions" section below.

You shouldn’t take Viagra with illegal drugs called poppers. Poppers contain nitrate drugs such as amyl nitrate, alkyl nitrate, and butyl nitrate. Taking Viagra with poppers can cause a dangerous drop in your blood pressure that can lead to heart attack or stroke. However, if you have high blood pressure that’s managed with medication and you also don’t have a heart condition, it’s usually fine to take Viagra.

Experts believe around 30–50 million American men have experienced ED at some point. It can happen at any age but becomes more common as men get older. By the time a man is in his 40s, he has about a 40% chance of having experienced ED at some point. That likelihood increases by about 10% for each decade of life (Ferrini, 2017; Sooriyamoorthy, 2021).

That is why you must discuss it with your doctor before you start Viagra. The drug is capable of many drug-drug interactions causing unpleasant side effects or reducing the potency of other drugs you take. However, psychological dependence may be seen in some people. It is therefore advised to take it only as directed and in recommended doses. Viagra typically starts to work within 30 minutes to 1 hour after ingestion.

ED is when you can't get or keep an erection long enough to have satisfying sex. That includes erections that aren't as firm or don't last as long as you'd like. Some people with ED have trouble getting morning erections as well.

Such countries are known to have equally advanced pharmaceutical and pharmacy regulatory systems.

Results with all doses have been pooled, but scores showed greater improvement at the 50 and 100 mg doses than at 25 mg. The pattern of responses was similar for the other principal question, the ability to achieve an erection sufficient for intercourse. The titration studies, in which most patients received 100 mg, showed similar results.

By inhibiting this enzyme, more blood can flow to where it is needed. And, with greater blood flow, the chances that you will achieve and maintain an erection increase, too. This is why medicines like Viagra – and its generic unbranded version, Sildenafil (or Viagra Soft Tabs Sildenafil Citrate) – are both so popular and so little understood by the general population. Although ED is common, we don’t talk about it as much as we should – and if we come to need the treatments, we don’t really know what it all entails. As such, men usually have a lot of questions about the drug – and that’s perfectly normal.

If use of a nitrate-containing medication is considered medically necessary, you must wait 48 hours after the last dose of sildenafil before taking a nitrate, and only under close medical supervision. Other medical conditions you have can also affect your Viagra dosage. Specifically, you may have a lower starting dosage than usual if you’re over age 65. For example, a 30-year-old might start at a dose of 50 milligrams (mg), while a 70-year-old might have a starting dose of 25 mg.

Sharing this information can help you avoid potential interactions. This is because certain side effects of Viagra may be worsened by alcohol, including headaches, flushing, and dizziness. And drinking lots of alcohol can also make it more difficult to get an erection. If Viagra doesn’t seem to work for you, talk with your doctor. They may increase your dosage or recommend that you try a different medication.

In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to sildenafil. If this happens during or after sex and you are taking nitrates, do not take them to treat your chest pain. Serious side effects are rare and happen in less than 1 in 1,000 people. Viagra 100 mg Tablet is not recommended for children under the age of 18. You are advised not to consume alcohol as it might temporarily impair your ability to get an erection.

Another study conducted at the University of Toronto examined the interaction of sildenafil with other drugs such as nitrates and alpha blockers. The results showed that the combined use of sildenafil with nitrates can lead to serious side effects such as hypotension (decreased blood pressure). Viagra is usually taken only when needed, 30 minutes to 1 hour before sexual activity.

Viagra is remarkably well tolerated and free from significant side effects in the vast majority of men who take it. Viagra increases blood flow which can have adverse effects on other parts of the body, although these are usually mild. Most men who experience side effects carry on treatment regardless.

If VIAGRA does not help you to get an erection, or if your erection does not last long enough for you to complete sexual intercourse you should tell your doctor.

Viagra helps to increase blood flow to the penis so that a man can get and keep an erection. It is also used to treat pulmonary arterial hypertension (PAH), a type of high blood pressure that affects the heart and lungs. Common side effects of Viagra include headache, facial flushing, indigestion, stuffy or runny nose, and dizziness.

Talk with your doctor if you have questions or concerns about your current dosage. If any of the above factors apply to you, talk with your doctor. They may lower your dosage to 25 mg of Viagra, instead of 50 mg. The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. In some cases, doctors may adjust your dosage from those shown below.

However, you should always be open and honest in the medical questionnaire before progressing with your treatment. For example, if you’ve had a cardiac issue such as a stroke or heart attack in the previous 6 months, PDE5 inhibitors like Sildenafil and Tadalafil should be avoided. It’s important to give a true account of your health and medical history – to allow your clinicians to supply safe medication for you. You can get sildenafil on the NHS if you have certain medical conditions, such as diabetes. If you require more than this, you are required to obtain treatment privately.

Avanafil is the active ingredient in Spedra tablets which tackles ED. It is a PDE-5 inhibitor — a drug that increases the blood flow to your penis once you have become aroused. This blood flow will only occur during sexual stimulation; using Spedra doesn’t mean you will achieve an erection as soon as you take the tablet.

Studies in vitro have shown that sildenafil is selective for PDE5, which is involved in the erection process. Its effect is more potent on PDE5 than on other known phosphodiesterases. There is a 10-fold selectivity over PDE6 which is involved in the phototransduction pathway in the retina. At maximum recommended doses, there is an 80-fold selectivity over PDE1, and over 700-fold over PDE2, 3, 4, 7, 8, 9, 10 and 11. In particular, sildenafil has greater than 4,000-fold selectivity for PDE5 over PDE3, the cAMP-specific phosphodiesterase isoform involved in the control of cardiac contractility. As dizziness and altered vision were reported in clinical trials with sildenafil, patients should be aware of how they react to VIAGRA, before driving or operating machinery.

Do not take more or less of it or take it more often than prescribed by your doctor. The products discussed in this site may have different product labeling in different countries. The information provided is for educational purposes only and is not intended to replace discussions with a healthcare provider. VIAGRA does not protect against sexually transmitted diseases, including HIV.

It’s worth noting, however, that these medications do not increase sexual desire. Instead, they allow the penis to better fill with blood and achieve a satisfactory erection. With both of these drugs, however, patients must realize that they do not have 100% success and that the success rate has a lot to do with the severity of ed.

A dose of Viagra will completely leave your system within about 20 to 24 hours. A doctor may adjust someone’s dosage of Viagra based on their age and medical history. For example, men older than 65 or those with hepatic or renal impairment are typically given a starting dose of 25 mg. The standard dose of Viagra for ED is 50 mg taken as needed, about one hour before sexual activity. According to manufacturer instructions, Viagra should only be taken once per day on an as-needed basis unless otherwise advised by a doctor.

Rarely, sildenafil can cause temporary color vision changes. If you have an eye condition called retinitis pigmentosa, check with your healthcare provider before using PDE5 inhibitors like sildenafil. It may also increase the risk of non-arteritic ischemic optic neuropathy (NAION) in some people––this is an eye problem that can lead to vision loss.

No worries, in this post, we'll explore the key factors to consider when selecting your treatment dosage for ED. There are other FDA-approved drugs to treat low libido in women. Simply put, Viagra (sildenafil) works by improving the blood supply to the genitals. This helps in venous engorgement in the penile tissue and thus a stronger erection. It also cuts down the refractory period in men, that is a man using Viagra can get the next erection within 10 minutes, rather than 20 (which is normal). If you have found Sildenafil 100mg to be ineffective, you should talk to your prescribing doctor.

Other drugs that operate by the same mechanism include tadalafil (Cialis) and vardenafil (Levitra). Consider a starting dose of 25 mg in patients treated with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, or saquinavir) or erythromycin. Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see Drug Interactions (7.4) and Clinical Pharmacology (12.3)]. Population pharmacokinetic analysis of clinical trial data indicated a reduction in sildenafil clearance when co-administered with CYP3A4 inhibitors (such as ketoconazole, erythromycin, cimetidine). Although no increased incidence of adverse events was observed in these patients, when sildenafil is administered concomitantly with CYP3A4 inhibitors, a starting dose of 25 mg should be considered. Most, but not all, of these patients had pre-existing cardiovascular risk factors.

In some cases, if the root of your ED is psychological, counselling may be helpful. ED caused by physical injury or an underlying condition, meanwhile, may improve with focused treatment, or lifestyle changes such as weight loss and exercise.

If you start to experience any serious side effects when taking sildenafil, you should talk to your healthcare practitioner at Felix immediately. They may be able to suggest alternative medications or dosages that may work better for you. Drinking alcohol whilst taking sildenafil can be safe, but only if you are drinking in moderation. Excess alcohol consumption can intensify side effects, and even contribute to erectile dysfunction. Alcohol slows down certain functions of the body, and constricts blood vessels, limiting blood flow to the penis.
