Vidalista Yellow (Sildenafil) Buyer and Patient Handbook in Singapore

What is Vidalista Yellow?

Vidalista Yellow is a 80 mg tablet containing sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor used to treat Erectile Dysfunction (ED). It belongs to the class of oral agents that improve blood flow to the penis during sexual stimulation. The product is approved by the Health Sciences Authority (HSA) of Singapore and is available in a convenient pill form.

Who Should Use Vidalista Yellow?

• Men aged 18 years and older who experience consistent difficulty achieving or maintaining an erection suitable for intercourse.
• Individuals whose ED is not caused by severe cardiovascular disease, uncontrolled Hypertension, or recent myocardial infarction.
• Patients who have been cleared by a qualified health professional to use a PDE-5 inhibitor.

How Does It Work?

Sildenafil blocks the enzyme PDE-5, which normally degrades cyclic guanosine monophosphate (cGMP). By inhibiting PDE-5, cGMP levels remain high, causing smooth-muscle relaxation and increased blood flow to the corpora cavernosa during sexual arousal. Think of it as unlocking a valve that allows more blood to enter the penis when you are excited. The effect starts within 30-60 minutes and can last up to 12 hours.

Why Choose Vidalista Yellow?

• Convenient dosing: A single 80 mg tablet is taken as needed, eliminating daily medication for many users.
• Cost-effective: Compared with many brand-name equivalents, Vidalista Yellow offers similar clinical efficacy at a lower price point.
• Proven safety profile: Sildenafil has been extensively studied worldwide, with well-documented benefits and risks.

Off-label uses (e.g., Pulmonary Arterial Hypertension) should only be considered under specialist supervision.

• Do not exceed one tablet within a 24-hour period.

How to Take

• Swallow the tablet whole with a glass of water.
• It can be taken with or without food; however, a high-fat meal may delay onset.

Missed Dose

Overdose

• If you suspect an overdose (e.g., more than one tablet), seek immediate medical attention. Symptoms may include severe headache, blurred vision, or low blood pressure.

Precautions and Warnings
