Pediatric Indications and Dosage
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. 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. Viagra and Cialis are both brand-name drugs.
What happens if I miss a dose?
(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.

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.
What should I tell my healthcare provider before taking sildenafil?

The actual price you’ll pay for either drug depends on your insurance plan, your location, your prescribed dosage, and the pharmacy you use. In addition to being available as the brand-name drug Viagra, it’s available as a generic drug. Here we look at how Viagra and sildenafil are alike and different.
What should I do if I forget 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. And it’s approved only to treat ED, not to be used recreationally.
Special Populations
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. If you’re interested in finding an alternative to Viagra, talk with your doctor. Viagra, which contains the active drug sildenafil, is a brand-name drug. But sildenafil is also available as a generic medication. A generic medication is an exact copy of the active drug in a brand-name medication.

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).

Key takeaways
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. 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. 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.
