A similar study reported a consistent result, with a risk estimate of 2.27 (95% CI 0.99, 5.20).

A doctor might prescribe Sildenafil 20mg for erectile dysfunction if they want to try you on a slightly lower dose. For example, if you’ve had a mild reaction to higher doses of sildenafil before, or if you’ve got a medical condition that means you’re more susceptible to side effects, you might be given the 20mg dose. Sildenafil 50mg is the middle dose and the one that most men will be introduced to. Starting here gives your clinician the opportunity to increase or decrease the dosage depending on how your body reacts to the treatment. It offers a great starting point, with 74% of patients in a fixed dose study reporting improved erections when using 50mg .

VIAGRA film-coated tablets are blue, with a rounded-diamond shape. They are marked "VIAGRA" on one side and "VGR 25", "VGR 50" or "VGR 100" on the other side. The tablets are provided in blister packs containing 2, 4, 8, 12 or 24 tablets. Do not use this medicine after the expiry date which is stated on the carton and blister after EXP. Do not take VIAGRA film-coated tablets in combination with VIAGRA orodispersible tablets.

Doses of 200 mg did not result in increased efficacy but the incidence of adverse reactions (headache, flushing, dizziness, dyspepsia, nasal congestion, altered vision) was increased. Caution is advised when sildenafil is administered to patients taking an alpha-blocker, as the co-administration may lead to symptomatic hypotension in a few susceptible individuals (see section 4.5). This is most likely to occur within 4 hours post sildenafil dosing.

It has an advantage over sildenafil as it works in as little as 30 minutes, and has a longer duration of up to 36 hours. However, this can be a disadvantage if you experience side effects, as they are also likely to last longer. You should not take more than one sildenafil tablet within a 24-hour period.

If you’ve been prescribed ED medication in the past, or if you are looking for a prescription now, you will undoubtedly be asked whether you take nitrates. Nitrates like nitroglycerin can cause a sudden drop in blood pressure and even lead to heart attack or stroke. Patients on nitroglycerin typically have serious cardiovascular issues that make taking ED medication risky in the first place. Patients taking recreational "poppers," including amyl nitrate, amyl nitrite, and butyl nitrate, should not take ED medication.

If you experience any side effects, stop using the medication and seek immediate medical attention. When taken as prescribed, Viagra can help you get hard so you can engage in sexual activity but do not expect it to do all the work. Moderate to heavy drinking can make it — er — harder for you to get an erection.

Physicians should advise patients of the potential for VIAGRA to augment the blood pressure lowering effect of alpha-blockers and anti-hypertensive medications. Concomitant administration of VIAGRA and an alpha-blocker may lead to symptomatic hypotension in some patients. The AUC of the active metabolite, N-desmethyl sildenafil, was increased 62% by loop and potassium-sparing diuretics and 102% by nonspecific beta-blockers. These effects on the metabolite are not expected to be of clinical consequence.

For severe side effects such as prolonged erections and loss of vision or hearing, stop taking the drug and immediately seek medical attention. Sildenafil is used to treat erectile dysfunction, a condition where you are unable to get or keep an erection firm enough to have sexual intercourse. It works by relaxing the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. This medicine will only help you to get an erection if you are sexually stimulated. Concomitant administration of sildenafil to patients taking alpha-blocker therapy may lead to symptomatic hypotension in a few susceptible individuals.

And there isn’t enough evidence to show that Viagra works for treating sexual problems in females. It hasn’t been studied in people younger than 18 years of age. If you have questions about using Viagra for Raynaud’s disease, talk with your doctor. With Raynaud’s disease, the blood vessels in your hands and feet spasm and temporarily become narrowed. These narrowed blood vessels restrict blood supply to your fingers or toes. This can cause your fingers and toes to look white and feel cold, painful, or numb.

(An active ingredient is what makes a drug work.) Viagra belongs to a group of drugs called phosphodiesterase 5 (PDE5) inhibitors. The use of VIAGRA offers no protection against sexually transmitted diseases. VIAGRA is rapidly absorbed after oral administration, with a mean absolute bioavailability of 41% (range 25–63%). The pharmacokinetics of sildenafil are dose-proportional over the recommended dose range. It is eliminated predominantly by hepatic metabolism (mainly CYP3A4) and is converted to an active metabolite with properties similar to the parent, sildenafil.

At least two-thirds of men have improved erections after taking it. For men with ED, their nerves aren’t properly stimulated, and so blood doesn’t flow properly into the penis. Viagra helps as it contains an active ingredient called sildenafil citrate, a PDE-5 inhibitor. This relaxes the walls of the blood vessels, allowing blood to flow more easily into the penis to cause an erection. When choosing one, tell your doctor or other health care professional what your preferences are, such as cost, ease of use, how long the drug's effects last and side effects. Generic versions of sildenafil, vardenafil and tadalafil are available.

Other drugs may interact with sildenafil, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide. Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers". Taking sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Sildenafil is also used in both men and women to treat the symptoms of pulmonary arterial hypertension. This is a type of high blood pressure that occurs between the heart and the lungs.

Consult your doctor if any of the side effects trouble you. Always take this medicine exactly as your doctor or pharmacist has told you. Erectile dysfunction (ED) can be a sign of an underlying medical condition, such as reduced circulation, diabetes, high cholesterol, or a neurological or hormonal issue. These things need to be assessed by a doctor face-to-face, which may include tests, and men taking ED tablets should have check-ups periodically.

If you feel that the effect of VIAGRA is too strong or too weak, talk to your doctor or pharmacist. You should take VIAGRA about one hour before you plan to have sex. You should be aware of how you react to VIAGRA before you drive or use machinery. Our doctors review all orders and issue new or repeat prescriptions online direct to our pharmacy.

Sildenafil (generic Viagra) is an erectile dysfunction treatment. It is a cost-effective option and well tolerated by most men. Sildenafil tablets take around minutes to work and lasts for up to 4 hours. This is when a man cannot get, or keep, a hard erect penis suitable for sexual activity. Ask your doctor if you have any questions about why this medicine has been prescribed for you. Viagra is not available at a dose of 20mg, but the generic version of it is.

It may also be prescribed off-label for ED at 20 mg, 40 mg, 60 mg, 80 mg, and 100 mg doses. Increasing your dosage in smaller increments can make finding an optimal dose easier for you and your healthcare provider (DailyMed, 2020). Viagra works by increasing blood flow to the penis so you can get hard enough, long enough to engage in sexual activity. If you are taking sildenafil for erectile dysfunction, your doctor will probably start you on an average dose of sildenafil and increase or decrease your dose depending on your response to the medication.

The usual recommended dose is 50 mg taken as needed, approximately 30 to 60 minutes before sexual activity. However, the medication may be taken any time from 4 hours to half an hour before sexual activity. Based on the effectiveness and side effects of the medication, the dose may be increased to 100 mg or decreased to 25 mg. In February 2007, it was announced that Boots, the UK pharmacy chain, would try over-the-counter sales of Viagra in stores in Manchester, England. VIAGRA was administered to more than 3,000 patients aged 19 to 87 years, with ED of various etiologies (organic, psychogenic, mixed) with a mean duration of 5 years. VIAGRA demonstrated statistically significant improvement compared to placebo in all 21 studies.

It can help you get and keep an erection if you’re sexually stimulated. Viagra tablets are a branded ED treatment, containing the active ingredient sildenafil. The active ingredient in Viagra is sildenafil, which is known medically as a PDE5 inhibitor.

It is generally recommended to limit alcohol consumption while using Viagra. Alcohol can impair sexual performance and increase the risk of side effects like dizziness and headaches. Excessive alcohol intake may also reduce the effectiveness of Viagra.

Read the drug information contained in the package from the drug manufacturer. If you don’t understand the instruction on how to take Viagra, ask your healthcare provider or pharmacist to explain. For this reason, a person who is 65 years of age or older may be started on a lower Viagra dose, typically 25 mg. In contrast, a young man with no significant health conditions is usually prescribed Viagra 50 mg as a starting dose. Also, men taking certain medications called alpha-blockers may need to take a lower dose of Viagra. Alpha-blockers are used to lower blood pressure and treat prostate disease (e.g., tamsulosin (Flomax), prazosin (Minipress), and doxazosin (Cardura)).

This is most likely to occur within 4 hours post sildenafil dosing (see sections 4.2 and 4.4). When sildenafil and doxazosin were administered simultaneously to patients stabilized on doxazosin therapy, there were infrequent reports of patients who experienced symptomatic postural hypotension. These reports included dizziness and light-headedness, but not syncope. With Viagra, you’ll take a dose between 30 minutes and 4 hours before you plan to have sex. With Levitra, you’ll take a dose about 1 hour before sexual activity. The medications can help you get an erection up to 4 hours after you take a dose.

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.

They may increase your dosage or recommend that you try a different medication.

Caution is advised when PDE5 inhibitors are co-administered with alpha-blockers. PDE5 inhibitors, including VIAGRA, and alpha-adrenergic blocking agents are both vasodilators with blood pressure lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may occur. Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you.

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.
