Cialis, which is chemically known as tadalafil is used to treat erectile dysfunction in men. This drug is similar to Viagra and Levitra. If Tadalafil is under the name Adcirca, it is used for treating pulmonary arterial hypertension.
How does Cialis Work
An erection occurs when the penis is filled with blood. This occurs because the blood vessels allow the penis to dilate by increasing the blood supply. When a man can not get an erection, it is because the blood flow to his penis has not increased. A man also lacks cGMP, which controls blood flow to and from the penis. Cialis uses Nitric oxide to aid the blood vessels in contracting, and it also helps blood flow in and out of the penis. The substance PDE5 is an issue that can kill an erection. Tadalafil stops PDE5 from destroying cGMP allowing the erection to last longer.
How to use Cialis
It can be used in doses of 5, 10, and 20 milligram doses. Patients suffering from erectile dysfunction should take it as needed, but it should not be taken more than once every 24 hours. A man must be sexually aroused before taking Cialis. The drug will not work if he is not, as it does not provide an erection without sexual stimulation. A dose of 10 milligrams should be taken at least thirty minutes before any sexual activity. The maximum dose that should ever be taken is 20 milligrams. As the drug can remain in the system for at least 24 hours, it is not recommended that the patient takes 10 to 20 milligrams a day. If the patient plans to be sexually active at least twice a week, they can take Cialis daily in a dose of 5 milligrams.
Depending on the reaction to the drug, that can be reduced to 2.5 milligrams once daily. Cialis should not be taken by anyone under the age of 18, or by anyone who is not suffering from erectile dysfunction.
Side Effects of Cialis
If Cialis is taken with a nitrate medication, it can cause a serious and sudden drop in blood pressure, leading to hypotension. If a man has a nitrate drug prescription for treating heart problems, or chest pain, he should not be using tadalafil. If certain symptoms occur during sexual activity, they could be a sign of a serious complication. Seek medical assistance in the event any of these side effects occur:
- or tingling or pain in the jaw, the arms, the chest, or the neck
An erection lasting more than 4 hours is called priapism and it can cause damage to the penis. In this case, seeking medical help is necessary, too. Very rarely, Cialis can undermine blood flow to the optic nerve of the eye. This can cause sudden loss of vision. However, this side effect is not very common and will likely only occur in patients with hypertension, diabetes, high cholesterol, pre-existing eye problems, or heart disease. If you suffer from any of the following conditions, you should not take Cialis:
- heart rhythm problems
- angina or any kind of heart disease
- high or low blood pressure (hypertension or hypotension)
- congestive heart failure or stroke within the last six months
- myocardial infarction within the last three months
- sickle cell anemia
- multiple myeloma
- leukemia or another blood disorder
- liver or kidney disease
- stomach ulcer
- retinitis pigmentosa
- structural deformity of the penis
- Peyronie’s disease (or any health condition for which you have been advised not to have any sexual intercourse)
The FDA has warned that sudden hearing loss has been experienced by people using tadalafil and similar products. They have also announced that it may increase your risk of melanoma skin cancer.
Where to get Cialis
Cialis can only be prescribed and used under supervision of a medical professional. The FDA issued a warning in 2015 about counterfeit tadalafil tablets that have become available in the U.S.
Compare and Contrast Viagra and Cialis
Cialis and Viagra have most of the same common side effects. As far as Viagra goes, the maximum dose is 100 milligrams daily, where as Cialis is 20 milligrams. Viagra needs to be taken one hour before sexual activity, where with Cialis, it needs to be taken 30 minutes before sexual activity. An erection with Cialis can last 18 hours, and with Viagra, it can last from 4-6. Neither pill should be taken by pregnant women.
