Cialis is an FDA-approved medication used to treat male impotence. It’s unique among male impotence medications because it can last for up to 36 hours. Eli Lilly & Co. manufactures Cialis in the United States.

Cialis treats male impotence by relaxing penile muscles and increasing blood flow, facilitating an erection once you are sexually aroused. In most cases, Cialis will allow you to get and maintain an erection sufficient for sexual intercourse. After a sexual encounter, your erection will go away until you become aroused again.

Cialis is the only male impotence medication that can remain effective for up to 36 hours. This can be a benefit, because you won’t feel rushed to have sex right away. Cialis also starts working quickly. Since it starts working in as few as 30 minutes, it’s possible to have spontaneous sex whenever the mood is right.

In clinical trials, Cialis has been shown to work well for men with mild to severe male impotence. It’s easy and convenient to use Cialis, because you can take it with or without food.

Only take Cialis as instructed by your physician. Cialis works best if taken approximately 30 minutes before a sexual encounter. After taking Cialis, you will not get an erection until you are sexually stimulated. After sex, your erection will go away until you’re sexually aroused again. The effects of Cialis can last up to 36 hours, so it’s possible to get more than one erection per dose.

Cialis is generally well tolerated, but side effects are possible. Common minor side effects include headache, stomach upset, muscle pain and soreness, skin flushing, and nasal congestion. These minor side effects should not last more than 24 hours.

In some cases, muscle pain and soreness can start approximately 12 to 24 hours after taking Cialis. These side effects should subside within 48 hours. Tell your doctor if you experience more serious or persistent side effects when taking Cialis.

Before prescribing Cialis, your doctor will want to review your complete medical history and current health status. Tell your doctor if you have any health issues, including angina, heart failure, high blood pressure, low blood pressure, liver problems, kidney problems, ulcers, bleeding disorders, leukemia, or sickle cell anemia. Tell your doctor if your penis has any anatomical abnormalities or if you have ever had an erection that lasted more than 4 hours. After reviewing your medication history, your doctor will be able to determine if it’s safe for you to take Cialis.

Give your doctor a list of all your current prescription and non-prescription medications. This includes over-the-counter medications, vitamins, and herbal supplements. Cialis may interact with several medications, including nitrates, alpha-blockers, Flomax, Minipress, Uroxatral, and erythromycin. Never take Cialis with other medications used to treat male impotence. Your doctor will review your health information and list of current medications to determine if it’s safe for you to take Cialis.
