Tadalafil offers something sildenafil can't: a daily low-dose option that maintains consistent levels for spontaneous, ongoing vitality. Physician-prescribed through Eros MD. Discreetly delivered.
about Tadalafil
Tadalafil is a PDE5 inhibitor, the same class of medication as sildenafil. It was FDA-approved in 2003 under the brand name Cialis and became available as a generic in the United States in 2018. Like sildenafil, tadalafil works by blocking the PDE5 enzyme to improve blood flow to the penis, supporting the ability to achieve and maintain erections.
What sets tadalafil apart is its duration of action: up to 36 hours, compared to 4-6 hours for sildenafil. This has earned it the nickname 'the weekend pill.' But tadalafil's most distinctive feature is its availability as a daily low-dose formulation: 2.5mg or 5mg taken every day, which maintains consistent blood levels without requiring a dose before each sexual encounter.
Notably, daily tadalafil is also FDA-approved for benign prostatic hyperplasia (BPH), a prostate condition common in men over 50. This makes it a uniquely multifunctional medication for men managing both conditions simultaneously.
Eros MD positioning
Daily tadalafil aligns particularly well with Eros MD's longevity medicine positioning. For men who see health as ongoing optimization rather than reactive treatment, daily tadalafil provides consistent vascular support and removes the 'transactional' nature of on-demand dosing. It is the difference between treating ED and supporting vitality.

the details
Daily dosing is 2.5mg or 5mg taken at the same time each day, every day, regardless of whether you plan sexual activity. As-needed dosing is 10mg or 20mg taken 30-60 minutes before sexual activity, with no more than one dose in 24 hours. Tadalafil can be taken with or without food, and food interaction is minimal compared to sildenafil. Your Eros MD provider determines the appropriate dose and regimen based on your health profile, goals, and any relevant medications or conditions.

Eros MD Safety Process
Your Eros MD provider reviews your full medical history and current medications before prescribing tadalafil.
How it works
The process is straightforward, private, and physician-led. Here's what to expect:
Complete your confidential health assessment, 5-10 minutes. Covers your symptoms, health history, current medications, and whether you prefer daily or as-needed treatment.
A licensed Eros MD physician reviews your intake and determines if tadalafil is appropriate for your health profile.
If prescribed, your provider recommends the appropriate dose and formulation, daily or as-needed, based on your goals and health history.
Medication is dispensed from a licensed pharmacy and delivered in discreet, unmarked packaging.
Follow-up support included. Your provider can answer questions and adjust dosage as needed.
Questions worth asking
Yes. Tadalafil is the active ingredient in Cialis. Generic tadalafil contains the same active ingredient at the same doses, manufactured to the same FDA bioequivalence standards. Generic tadalafil has been available in the US since 2018.
Tadalafil can remain effective for up to 36 hours following a dose, significantly longer than sildenafil's 4-6 hours. This is why it is often referred to as 'the weekend pill.' Effects vary by individual.
Yes. Tadalafil is the only PDE5 inhibitor FDA-approved for daily use. Daily doses of 2.5mg or 5mg maintain consistent blood levels, eliminating the need to plan around a dose. Your provider will recommend whether daily or as-needed use is more appropriate for you.
Daily tadalafil has an established long-term safety profile. It is FDA-approved for daily use for both erectile dysfunction and BPH. Long-term use should be monitored by a licensed physician, which Eros MD provides as part of your ongoing care plan.
Tadalafil and sildenafil are both highly effective, and neither is clinically 'better' in an absolute sense. Tadalafil has a longer duration and a daily option, making it preferable for men who want more spontaneity. Sildenafil has a slightly faster onset and is better suited for planned, on-demand use. Your Eros MD provider will recommend based on your profile and preference.
The most common side effects include headache, flushing, back pain, muscle aches, and nasal congestion. Back pain and muscle aches are somewhat more common with tadalafil than sildenafil and typically appear 12-24 hours post-dose. They are usually mild and resolve within 48 hours. Serious side effects are rare and screened for during your provider assessment.
