In addition, sildenafil also comes as 20-mg tablets, an oral liquid suspension, and a solution given by injection. These forms of sildenafil are generic versions of a brand-name drug called Revatio. But unlike Viagra, they’re not used to treat ED. Revatio and these forms of sildenafil are used to treat pulmonary arterial hypertension (PAH).
With PAH, you have high blood pressure in the artery between your heart and lungs.

This means that generic sildenafil is just as effective in treating ED as Viagra is when it’s taken at the same doses as Viagra.
Viagra and Cialis are both approved to treat ED in males ages 18 years and older. These drugs work to treat ED by helping you get and maintain an erection when you’re sexually aroused. But the drugs don’t work if you’re not aroused. In addition, Cialis is approved to treat symptoms caused by benign prostatic hyperplasia (BPH). BPH refers to having an enlarged prostate.
These symptoms include needing to pass urine frequently or urgently. They can also include having a weak flow of urine or being unable to fully empty your bladder. Viagra and Cialis both come as tablets that you take by mouth. With Viagra, you’ll take the drug between 30 minutes and 4 hours before you plan to have sex. The medication can help you get an erection up to 4 hours after you’ve taken a dose.
Viagra shouldn’t be taken more than once a day. With Cialis, you’ll take a dose at least 30 minutes before you plan to have sex. This medication can help you get an erection up to 36 hours after you’ve taken a dose. Cialis shouldn’t be taken more than once a day. While you can take Cialis just as needed for ED treatment, another option is to take a low dose of the drug regularly each day. It also means that sildenafil and Viagra can cause the same side effects. For information on the possible side effects of Viagra, see the “Viagra side effects” section.
The actual price you’ll pay for either drug depends on your insurance plan, your location, and your prescribed dosage. Like Cialis (described above), Levitra is also prescribed for similar uses as Viagra.

The generic form has the same use, dosage, safety, and effectiveness as the brand-name drug. The information about Levitra in this article also applies to vardenafil unless otherwise noted. Viagra contains the drug sildenafil, while Levitra contains the drug vardenafil. Both Viagra and Levitra belong to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra and Levitra are both approved to treat erectile dysfunction (ED) in males ages 18 years and older. Viagra and Levitra both come as tablets that you take by mouth. 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.
Doing this can help you to get an erection at any time when you’re sexually aroused. This may help make sex more spontaneous for you. Viagra and Cialis both contain the same type of drug. Therefore, these medications can cause very similar side effects. Below are examples of these side effects.
These lists contain up to 10 of the most common mild side effects that can occur with Viagra, with Cialis, or with both drugs (when taken individually). Can occur with Viagra:mild and temporary vision changes, such as a blue tinge to your vision, blurred vision, or sensitivity to lightnauseadizzinessrash mild and temporary vision changes, such as a blue tinge to your vision, blurred vision, or sensitivity to light Can occur with Cialis:pain in your arms or legsupper respiratory tract infectioncoughdiarrhea Can occur with both Viagra and Cialis:headacheflushingindigestionnasal congestion (stuffy nose)back painmuscle pain The following list contains examples of serious side effects that can occur with either Viagra or Cialis. priapism (long-lasting and sometimes painful erection) non-arteritic anterior ischemic optic neuropathy (NAION), which is an eye condition that causes damage to your optic nerve low blood pressure, if the drugs are taken with certain other medications cardiovascular problems, such as heart attack, irregular heartbeat, and stroke, all of which mainly occur in people with heart disease Viagra and Cialis have different approved uses, but they’re both used to treat ED. The use of Viagra and Cialis in treating ED has been directly compared in several clinical studies. One review of these studies found the two drugs were similarly effective in improving the ability of males to have and maintain erections.
However, sildenafil 5mg for sale researchers found that people who took Cialis had improved confidence in their sexual ability. So, the people were more likely to prefer Cialis over Viagra. This is likely due to the long-lasting effect of Cialis, which allows people to have more spontaneous sex. (Cialis’s dosing schedule allows less planning for when you need to take a dose before having sex.) The study also found that males who took Cialis were more likely to have back or muscle pain than those taking Viagra. But people taking Cialis were less likely to have flushing compared with those taking Viagra. The medications can help you get an erection up to 4 hours after you take a dose. But neither drug should be taken more than once a day. Viagra and Levitra both contain the same type of drug.
Examples of other drugs that may be used to treat ED include: testosterone replacement therapy, which is only used if you have low levels of testosterone Natural and over-the-counter (OTC) products for treating ED are widely available, especially on the internet. However, these products have not been tested for safety or effectiveness by the Food and Drug Administration (FDA). Because the products aren’t regulated, there’s no way to be certain of what these products actually contain. If you want to try a natural or OTC product for ED, you should first discuss it with your doctor. The American Urological Association doesn’t recommend using products that contain yohimbine, ginseng, and l-arginine for ED treatment.
(This includes products that contain these ingredients either alone or in combination with other ingredients.) This is because there’s not enough evidence to say whether the products work. And these products may cause harmful side effects. Examples of products that contain one or more of these ingredients include Libido-Max and Extenze. You should also avoid products you can buy online without a prescription that claim either to be generic forms of Viagra or to contain sildenafil. (Sildenafil is the active drug in Viagra.) If these drugs are available without a prescription, that means that they haven’t been tested or approved by the FDA.
As a result, it’s unknown if they’re effective or safe. And there’s no guarantee that the products actually contain sildenafil. You may wonder how Viagra compares with other medications that are prescribed for similar uses. Here we look at how Viagra and Cialis are alike and different. Both Viagra and Cialis belong to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
