12.1 Mechanism of Action

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.

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, 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. A generic medication is an exact copy of the active drug in a brand-name medication.

Your Viagra dosage won’t be based on your weight, but it may be based on your age.

Uso recreativo

For example, people ages 65 years and older tend to get higher levels of Viagra in their blood after taking a dose. So, if you’re over 65 years of age, your doctor will usually recommend a starting dose of Viagra for you that’s lower than the typical starting dose. For example, they may recommend that you take 25 mg of the drug rather than 50 mg. No, you should not take Viagra if you don’t have ED. Viagra is a prescription medication that can have serious side effects.

Recreational use

And it’s approved only to treat ED, not to be used recreationally. You should only take Viagra if it’s been prescribed to you by a doctor who knows your medical history. If you and your doctor determine that Viagra is safe and effective for you, you can likely take it for as long as you continue to need it. Other drugs are available that can treat ED. Some may be a better fit for you than others. However, the active drug in Levitra is available as a generic medication called vardenafil.

8.1 Pregnancy

If you’re interested in finding an alternative to Viagra, talk with your doctor. They can tell you about other medications that may work well for you. 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.

Can Viagra be crushed, split, or chewed?

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.

Does Viagra treat ED that’s related to diabetes?

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 sildenafil 25 mg tablets medications that are prescribed for similar uses.

But neither drug should be taken more than once a day. Viagra and Levitra both contain the same type of drug.
