Basic and Cautionary Facts About Viagra

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. (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.

Does Viagra work the first time you use it?

Viagra and Cialis are both brand-name drugs. Generic forms of both drugs are available. Brand-name medications usually cost more than generics. 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. For example, if you have high blood pressure that’s not managed, your heart may not be healthy enough for sexual activity. (With unmanaged high blood pressure, your blood pressure is greater than 170/110 mmHg.) If this is the case, talk with your doctor about whether Viagra is safe for you. However, if you have high blood pressure that’s managed with medication and you also don’t have a heart condition, it’s usually fine to take Viagra. Just be aware that taking the drug could lower your blood pressure.

About this article

Can you take Viagra if you have high blood pressure?

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. Low blood pressure from Viagra usually isn’t a problem for most people. But if you’re taking a type of blood pressure drug called an alpha-blocker, taking Viagra might cause certain side effects.

• Blue sex pills do not protect against sexually transmitted infections; use condoms for protection.

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.
