Generic Udenafil Buyer and Patient Handbook in South Africa

What is Udenafil?

Generic Udenafil is a phosphodiesterase-5 (PDE-5) inhibitor indicated for the treatment of Erectile Dysfunction in adult men. It belongs to the same class as Sildenafil and Tadalafil and is supplied as oral tablets. The medication is approved by the South African Health Products Regulatory Authority (SAHPRA) and conforms to international quality standards.

Who Should Use Udenafil?

• Men aged 18 years and older experiencing difficulty achieving or maintaining an erection.
• Individuals whose erectile dysfunction is not caused by hormonal deficiencies or severe vascular disease.
• Patients seeking an on-demand oral option with a relatively rapid onset of action.

How Does It Work?

Udenafil blocks the PDE-5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP) in the penile tissue. By preserving cGMP, the drug enhances blood flow during sexual stimulation, allowing an erection to occur. Think of it as keeping the “traffic lights” green for longer on the road that supplies blood to the penis.

Why Choose Udenafil?

• Effective: Clinical studies show it restores erectile function in a high proportion of users.
• Convenient: Taken as a single oral tablet, typically 30 minutes before sexual activity.
• Cost-Effective: As a generic product, it offers the same therapeutic benefit as branded PDE-5 inhibitors at a lower price point.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

• One 100 mg tablet taken orally.

How to Take

• Swallow the tablet whole with a glass of water.
• Take it about 30 minutes before planned sexual activity; it can be effective up to 4 hours afterward.

Missed Dose

• Do not take a second tablet to “make up” for the missed dose.

Overdose

Udenafil does not cause physical or psychological dependence. It is intended for use as needed rather than continuously.
