Erectile dysfunction treatment online
Erectile dysfunction affects roughly 1 in 3 men over 40 and is highly treatable — most cases respond to FDA-approved oral medications (sildenafil, tadalafil, vardenafil). ED can also be an early sign of cardiovascular disease, so evaluation matters beyond the symptom itself. The FirstCall platform connects you with an independent, board-certified physician for same-day evaluation and, when clinically appropriate, a prescription sent to a pharmacy of your choice.

Understanding erectile dysfunction
Understanding the mechanism makes the commitment to treatment clearer — and the results more predictable.
Erectile dysfunction — the consistent inability to achieve or maintain an erection sufficient for satisfying sexual activity — affects men of all ages. Physical causes include cardiovascular disease, diabetes, hypertension, and low testosterone. Psychological causes include stress, anxiety, and depression. The majority of cases have a treatable physical component. ED is not a normal part of aging — it is a medical condition with highly effective treatment.
Key insight: ED is the most common male sexual health condition, yet fewer than 25% of affected men seek treatment. The barrier is almost entirely stigma — not access. Telehealth removes it entirely.
ED affects 30 million men — and most never seek treatment
Approximately 30 million American men experience erectile dysfunction. Yet the vast majority never discuss it with a physician. The gap between prevalence and treatment is almost entirely explained by stigma — the discomfort of sitting in a waiting room, speaking to a receptionist, or running into someone you know. FirstCall removes every one of those barriers. A 10-minute private consultation from your phone is all it takes.
What to expect
Set realistic expectations and stay consistent — results take time but are well-documented.
Sildenafil reaches full effect within 30–60 minutes. Best taken on an empty stomach for fastest absorption.
Daily low-dose tadalafil maintains continuous readiness — no timing required at all.
80–85% of men respond to their first ED medication. Dose adjustments are straightforward if needed.
PDE5 inhibitors maintain effectiveness long-term. No tolerance buildup or diminishing returns.
Two medications. One right for you.
Sildenafil (Generic Viagra®) works within 30–60 minutes and lasts 4–6 hours — ideal for planned intimacy. Tadalafil (Generic Cialis®) is available as a daily low-dose tablet for continuous readiness, or as an as-needed dose lasting up to 36 hours. Both are FDA-approved generics at a fraction of brand-name cost. Your physician will help you choose based on your lifestyle.
The science behind erectile dysfunction treatment
Evidence-based treatment addresses the underlying mechanism — not just the symptoms.
PDE5 inhibitors work by blocking phosphodiesterase type 5, an enzyme that restricts blood flow in the penis. By inhibiting PDE5, these medications allow smooth muscle relaxation and significantly increased blood flow — producing a natural erectile response when sexually aroused.
Sildenafil and tadalafil are among the most studied medications in men's health. Combined, they have been prescribed to hundreds of millions of men worldwide with a well-established safety and efficacy profile across more than 25 years of post-market data.
Sildenafil acts in 30–60 minutes. Tadalafil offers 36-hour windows or daily continuous protection. Whether you prefer spontaneity or planned intimacy, there is a formulation and dosing schedule that fits your life.

Frequently asked questions
Clear answers about erectile dysfunction treatment and how FirstCall works.
Do not take PDE5 inhibitors with nitrate medications (nitroglycerin, isosorbide) — this combination can cause a dangerous and potentially fatal drop in blood pressure. Not recommended for men with severe heart disease, recent stroke, or severely low blood pressure. Do not take more than one dose in 24 hours. Seek emergency care for erections lasting more than 4 hours (priapism). Read full prescribing information ›
