Sildenafil
A private starting point for understanding sildenafil, the active ingredient in Viagra, as an option for erectile dysfunction.
Tadalafil
Explore tadalafil, the active ingredient in Cialis, with an individual assessment and clear guidance about erectile dysfunction treatment.
Erectile function and sexual desire are different
Sildenafil and tadalafil support erectile function through the PDE5 pathway. They help blood flow during sexual stimulation; they do not directly increase sexual desire or address every cause of sexual difficulty.
ED can be associated with physical health, medicines, emotional factors or a combination of causes. Understanding what a medicine is intended to do helps distinguish an ED treatment from a general claim about libido or sexual performance.
Comparing sildenafil and tadalafil in practical terms
The two ingredients have different duration and scheduling considerations. Sildenafil for ED is generally used as needed. Cialis labeling includes both daily and as-needed regimens for tadalafil. The instructions for the exact prescription determine the relevant schedule.
A longer response window does not mean a continuous erection, and neither medicine should be combined with another ED product without specific prescriber direction. The individual pages explain these differences and link to prescribing information.
Safety information to identify before use
Nitrates, recreational nitrites and riociguat are important contraindicated combinations with these medicines. Other drugs and cardiovascular conditions can also affect safety. A familiar brand name or tablet color is not enough to identify a suitable product.
An erection lasting more than four hours and sudden changes in vision or hearing require urgent medical attention. Read the complete product information rather than treating a brief category summary as the full safety guidance.
An individual plan. Clear information.
Sildenafil and tadalafil require a prescription and a review of your cardiovascular health and other medicines. Do not use them with nitrates, recreational nitrites or riociguat. They are separate treatment options; do not combine them without specific prescriber direction.
