Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment. It is the generic version of Viagra, which means it contains the same active ingredient (sildenafil citrate) and works in the same way. If you take more than your prescribed dose, like taking 2 doses in 1 day, this can increase the risk of side effects and potentially dangerous complications, including permanent damage to your penis. When you take Viagra, the active ingredient, sildenafil, relaxes the smooth muscles in the penis blood vessels, increasing blood flow which causes an erection. Persistent erection problems can be a sign of an underlying condition, so if you experience erectile issues for a long time (even after taking erectile dysfunction tablets) you should consult your doctor.
Sildenafil and other PDE5 inhibitors should never be taken with nitrates. In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection.

If you experience any side effects, stop using the medication and seek immediate medical attention.

Your doctor may start you on the lower dose if you are taking certain medication, or you have a medical condition.

Here we look at how Viagra and Cialis are alike and different. Examples of products that contain one or more of these ingredients include Libido-Max and Extenze.

One of these chemicals, called cyclic GMP, relaxes and widens certain blood vessels in your penis. Cyclic GMP also relaxes the muscles around the erectile tissue in your penis that’s called the corpus cavernosum. These actions allow blood to flow into the corpus cavernosum, which causes your penis to get hard and become erect. This means that if you’re aroused, you should still be able to get an erection up to 4 hours after taking a dose of Viagra. Regardless of your age, you’ll take your prescribed dose about an hour before sex.

Yes, for most people, Viagra works the first time they use it. But for other people, it may take a few times of trying the drug to get the desired effect.

This is the biggest difference in approved dosages of Cialis compared with Viagra. The highest recommended Viagra dose for treating erectile dysfunction (ED) is 100 mg per day, according to the drug’s manufacturer. Doses of 150 mg or 200 mg would be considered off-label use. "Off-label" is when a drug is prescribed to treat a condition it isn’t approved to treat, or in a dose that’s not approved by the Food and Drug Administration (FDA). You can take the drug 30 minutes to 4 hours before you anticipate sexual activity. In fixed dose studies, the proportions of patients reporting that treatment improved their erections were 62% (25 mg), 74% (50 mg) and 82% (100 mg) compared to 25% on placebo.

It’s also important to store Viagra correctly and to not take expired medication. Storing Viagra at room temperature and away from moisture, heat, and sunlight will help make sure the medicine has the most extended shelf-life possible. The prescribing information recommends a maximum of one dose per day.
In the US, two medications have been approved to treat FSD. Known as Lady Era and Flibanserin, they may help to ease some of the symptoms of FSD, though more research is needed before these drugs are available to women in the UK.

This action improves blood flow to your penis and helps you get and keep an erection.
If priapism is not treated immediately, penile tissue damage and permanent loss of potency may result [see Warnings and Precautions (5.2)]. Physicians should advise patients to stop taking PDE5 inhibitors, including VIAGRA, and seek prompt medical attention in the event of sudden decrease or loss of hearing. These events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to the intake of PDE5 inhibitors, including VIAGRA. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Warnings and Precautions (5.4) and Adverse Reactions (6.2)].

Based on published literature, the annual incidence of NAION is 2.5–11.8 cases per 100,000 in males aged ≥ 50. The results suggest an approximate 2-fold increase in the risk of NAION, with a risk estimate of 2.15 (95% CI 1.06, 4.34). A similar study reported a consistent result, with a risk estimate of 2.27 (95% CI 0.99, 5.20). Other risk factors for NAION, such as the presence of "crowded" optic disc, may have contributed to the occurrence of NAION in these studies.
Around 30% of men who use Viagra or other ED treatments don’t experience the full benefits. There are physical and psychological causes of ED that can influence whether Viagra works or not. It is also important to ensure that you take Viagra in the correct way. The good news is that most of the reasons why Viagra is not working, can be easily resolved by making small changes. Like all medicines, Viagra can cause side effects in some people.
Sildenafil is the active ingredient in Viagra, so it works in the same way. This means it can be taken just as often as Viagra – even every day, if you’re seeking the desired effects this often. Erectile dysfunction (ED) is an extremely common condition. 40% of us experience it by the age of 40 – and that proportion increases the older we get. Branded medication is often more expensive than generic medication.

If you’re taking Viagra and have an erection that lasts longer than four hours (priapism), you should get emergency medical help as soon as possible. If you’re experiencing prolonged erections regularly, it’s best to talk with your healthcare provider about whether or not continuing to take Viagra is right for you. Viagra has been popular for decades, and recently Pfizer’s patent for the drug expired – allowing a generic unbranded medication, Sildenafil, to be produced and sold by accredited online pharmacies.

If you’re using Viagra, don’t use any other medications for ED without talking with your doctor.
The main measure of effectiveness was based on the ability of the men to get and maintain an erection. This was recorded in a special questionnaire completed at home using a scoring system on a five-point scale, where a score of 5 represents the best result. Viagra 25 mg is used to treat adult men with erectile dysfunction (sometimes called impotence), when they cannot get or keep a sufficiently hard penis (erection) for satisfactory sexual activity. For Viagra to be effective, sexual stimulation is required.
The concomitant administration of the protease inhibitor ritonavir substantially increases serum concentrations of sildenafil (11-fold increase in AUC). If VIAGRA is prescribed to patients taking ritonavir, caution should be used. Data from subjects exposed to high systemic levels of sildenafil are limited. Decreased blood pressure, syncope, and prolonged erection were reported in some healthy volunteers exposed to high doses of sildenafil (200–800 mg).

If you aren’t happy with your erections when taking the 50mg dosage, speak to your prescriber. The 100mg dosage is never used as a starting point for men new to Viagra.

These are some of most common prescription medications that customers searched for and ordered from our website. RxList does not provide medical advice, diagnosis or treatment.
As with any drug, never change your dosage of Viagra without your doctor’s recommendation. If you have questions about the dosage of Viagra that’s right for you, talk with your doctor.

Sildenafil at recommended doses has no effect in the absence of sexual stimulation. In fixed-dose studies, the incidence of some adverse reactions increased with dose. The type of adverse reactions in flexible-dose studies, which reflect the recommended dosage regimen, was similar to that for fixed-dose studies. At doses above the recommended dose range, adverse reactions were similar to those detailed in Table 1 below but generally were reported more frequently.
In studies with healthy volunteers of single doses up to 800 mg, adverse reactions were similar to those seen at lower doses but incidence rates and severities were increased. Analysis of the safety database from controlled clinical trials showed no apparent difference in adverse reactions in patients taking VIAGRA with and without anti-hypertensive medication. This analysis was performed retrospectively, and was not powered to detect any pre-specified difference in adverse reactions. Counseling of patients about the protective measures necessary to guard against sexually transmitted diseases, including the Human Immunodeficiency Virus (HIV), may be considered. However, there are no controlled clinical data on the safety or efficacy of VIAGRA in patients with sickle cell or related anemias. For example, a study conducted at McMaster University examined the effect of sildenafil on erectile function in men with diabetes mellitus.
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.
