Available only on prescription by a doctor for erectile dysfunction in adult men, Cialis is a drug that helps to achieve or maintain an erection effective enough to be able to have sexual intercourse. Be careful, however, of the possible side effects it can cause. Discover in this article all the essential information to know about the use of Cialis as well as its risks, dangers and side effects.

Available only on prescription from a doctor in adult men, Cialis is an oral medication whose active substance is Tadalafil, used in the treatment of erectile dysfunction.

How it works ?

Cialis promotes the rise of blood in the penis by causing the blood vessels to dilate. It works very similar to the action of Viagra.

More democratized than Cialis, Viagra was invented earlier, at the end of the 90s. While the two drugs have already proven their effectiveness, there are disparities between the two substances:

• Duration of effects: up to 8 hours with Viagra versus 36 hours with Cialis;
• A daily dose of Cialis (in accordance with a medical prescription) is possible, while Viagra is used in anticipation of sexual intercourse only; 
• The effects of Viagra can be altered by food, which is not the case with Cialis;
• Viagra works in about an hour, compared to 30 minutes with Cialis.

If Cialis lasts longer than when taking Viagra, there are also more contraindications to taking the drug. Cialis is not recommended if: 

• You have had a heart attack or stroke;
• You suffer from cardiovascular fragility;
• You have severe heart failure; 
• You have high blood pressure or low blood pressure;
• You are taking medicines containing nitrates;
• You suffer from a pathology related to the optic nerve. 

There are also side effects that vary from patient to patient, including:

• Headache ; 
• Dizziness;
• Hypersensitivity; 
• Acouphenes ;
• Redness of the face;
• Muscle pain ; 
• Heart problems that require prompt consultation with a healthcare professional.

What to do in case of a prolonged erection?

If the erection lasts more than 4 hours, it is recommended to consult a doctor quickly.

Cialis has the effect of facilitating an erection in case of sexual arousal. It has the particularity of acting over a longer period than Viagra, so it is possible to take it between 30 minutes and 12 hours before sexual intercourse. 

Personalized treatment?

Depending on the treatment set up by your doctor, it is also possible to set up a daily intake if you have frequent intercourse or if the planning of these represents a real brake on your sex life.

It is up to the attending physician to determine which of the two drugs will be more effective against the patient’s erection problems. Several decision-making factors will be taken into account, such as: 

• Medical history;
• The number of sexual relations per week;
• The desired duration of intercourse;
• An allergy to a component of one of the two drugs.

Perceive efficiency

It is estimated that it will take about 8 doses of the drug to perceive whether the action is effective or on the contrary whether it will be preferable to change the treatment.
