About Eriacta
Eriacta (Sildenafil) is a prescription-only oral tablet approved in Singapore for the treatment of erectile dysfunction, a condition that affects a significant proportion of adult men. Each 100 mg pill delivers the active ingredient sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor that improves penile blood flow during sexual stimulation. While the medication is primarily indicated for erectile dysfunction, clinicians sometimes consider it for other vascular-related conditions under specialist supervision. This article explains how Eriacta works, why it is prescribed, practical tips for safe use, and answers common questions you may have about incorporating it into your sexual health regimen.
What is Generic Eriacta (Sildenafil)?
Generic Eriacta (Sildenafil) belongs to the class of phosphodiesterase-5 inhibitors, a well-established group of drugs that target the enzyme responsible for breaking down cyclic guanosine monophosphate (cGMP) in the penis. In Singapore, the Health Sciences Authority (HSA) approved sildenafil for erectile dysfunction in 1998, and the tablet strength of 100 mg is a standard dose for many patients after titration. The product is marketed by Cipla, a globally recognized pharmaceutical company, and is manufactured under strict Good Manufacturing Practice (GMP) standards to ensure purity and consistency.
How Eriacta Works
Sildenafil exerts its effect by selectively inhibiting the PDE-5 enzyme found in the smooth muscle of the corpus cavernosum. During sexual arousal, nitric oxide (NO) is released from nerve endings and endothelial cells, stimulating the production of cGMP. Elevated cGMP causes relaxation of smooth muscle, allowing blood to fill the penile sinusoids and produce an erection. By blocking PDE-5, Eriacta prolongs the action of cGMP, enhancing and sustaining the erectile response.
Pharmacokinetically, sildenafil is absorbed rapidly, reaching peak plasma concentrations within 30-120 minutes after oral intake. Food, especially high-fat meals, can delay absorption by about an hour, which may affect the timing of onset. The drug is metabolized primarily by hepatic CYP3A4 and CYP2C9 enzymes, and its metabolites are excreted via the kidneys. The half-life of sildenafil is roughly 4 hours, meaning that its therapeutic effect typically wanes after 6-8 hours, allowing flexibility in dosing relative to planned sexual activity.
Why Eriacta is Used for Sexual Health Conditions
- Erectile Dysfunction (ED) - By restoring the NO-cGMP pathway, sildenafil directly addresses the physiological deficit that underlies most cases of organic ED. Clinical trials consistently show that 70-80 % of men achieve successful intercourse after taking a 100 mg dose, placing it as a first-line oral therapy in Singapore’s treatment guidelines.
- Premature Ejaculation (Adjunct) - Although not approved for this indication, some specialists prescribe low-dose sildenafil combined with behavioral techniques to improve control by prolonging erection latency.
- Pulmonary Arterial Hypertension (Off-label) - At lower daily doses (20 mg three times daily), sildenafil reduces pulmonary vascular resistance, improving exercise capacity in patients with this serious condition. This use is strictly off-label in Singapore and requires specialist supervision.
- Benign Prostatic Hyperplasia (Investigational) - Small studies suggest PDE-5 inhibition may relieve lower urinary tract symptoms by enhancing smooth-muscle relaxation in the prostate and bladder neck, though larger trials are needed before formal recommendation.
Off-Label and Investigational Uses of Eriacta
Beyond its approved role in erectile dysfunction, sildenafil has been explored for several off-label indications. Randomized controlled trials in pulmonary arterial hypertension demonstrate improvements in six-minute walk distance and hemodynamic parameters, leading to an FDA-approved formulation (Revatio) for that condition. In Singapore, using Eriacta for pulmonary hypertension is considered off-label and should only occur under the care of a cardiopulmonary specialist. Preliminary data also suggest potential benefits in Raynaud’s phenomenon and certain forms of heart failure, but these findings remain experimental. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Eriacta Right for You?
Eriacta is most appropriate for adult men with a confirmed diagnosis of erectile dysfunction who have not responded adequately to lifestyle modifications or non-pharmacological therapies. Suitable candidates are generally in good cardiovascular health, as sexual activity imposes a modest increase in cardiac workload. Men with severe uncontrolled hypertension, recent myocardial infarction, or advanced heart failure should avoid PDE-5 inhibitors unless advised otherwise by a cardiologist. Pregnancy and breastfeeding are not relevant to the male patient, but partners should be aware that sildenafil does not affect female sexual function directly. Caution is also warranted in patients taking nitrates, certain antihypertensives, or potent CYP3A4 inhibitors (e.g., ketoconazole) due to the risk of profound hypotension.
Taking Eriacta Effectively
- Timing: Take the tablet about 30-60 minutes before anticipated sexual activity. If you have a high-fat meal, consider a longer waiting period to allow absorption.
- Dosage flexibility: The 100 mg strength is the most common starting point, but clinicians may start at 50 mg and titrate up based on efficacy and tolerability. Do not exceed one tablet per 24 hours.
- Missed dose: If you forget to take the tablet and the scheduled time has passed, skip it and resume the next planned dose. Do not double up.
- Alcohol and smoking: Moderate alcohol intake does not contraindicate use, but excessive consumption can blunt the erection-enhancing effect. Smoking impairs vascular health and may reduce overall efficacy.
- Travel: Keep tablets in their original packaging, stored at room temperature away from moisture. Carry a copy of the prescription if you cross international borders, as some countries require documentation for PDE-5 inhibitors.
Understanding Side Effects and How to Manage Them
Most men tolerate sildenafil well; the most common adverse events are mild and transient:
- Headache - Caused by vasodilation in cerebral vessels. Over-the-counter analgesics (e.g., paracetamol) are usually sufficient.
- Flushing - A warm sensation in the face or neck due to peripheral vasodilation. Wearing light clothing and staying in a cool environment can help.
- Indigestion - May occur if the tablet is taken with a large, fatty meal. Taking the medication with a light snack can reduce this effect.
- Nasal congestion - Resulting from increased blood flow to nasal mucosa. A saline nasal spray can provide relief.
Serious but rare reactions include sudden loss of vision (non-arteritic anterior ischemic optic neuropathy), hearing loss, or prolonged erections lasting more than 4 hours (priapism). If you experience any of these, seek immediate medical attention. Always inform your prescriber of new or worsening symptoms, especially if you start other medications that could interact with sildenafil.
