Viagra, or sildenafil, treats erectile dysfunction (ED), a condition affecting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
The medication is a phosphodiesterase-5 (PDE5) inhibitor. This means it blocks an enzyme that can restrict blood vessel dilation. This allows for improved blood flow, facilitating an erection in response to sexual stimulation.
Viagra isn’t a stimulant; it doesn’t cause erections spontaneously. Sexual stimulation is necessary for the medication to work.
Dosage typically ranges from 25mg to 100mg, taken as needed, about one hour before sexual activity. Your doctor will determine the appropriate dosage based on your individual needs and health status.
Common side effects can include headaches, flushing, nasal congestion, and visual disturbances. More serious side effects are rare but require immediate medical attention.
Consult your doctor before using Viagra. It’s not suitable for everyone, particularly individuals with certain heart conditions, low blood pressure, or those taking specific medications.
Always follow your doctor’s instructions carefully and discuss any concerns or questions you may have regarding the medication or potential side effects.
