What is the sildenafil capsule?

(sil-DEN-a-fil)

Sildenafil citrate powder in a capsule, swallowed with water. It works like the tablet: PDE5 blockade that keeps blood in the penis during arousal.

time to onset after swallowing

Slower after a heavy meal.

How it works,
week by week.

  1. Day 1

    A US-licensed physician reviews your health, medications (especially nitrates and blood pressure drugs) and goals, and chooses the dose and form.

  2. First doses

    Take it 30 to 60 minutes before intimacy, on a light stomach. Arousal is still needed; the medicine helps the response, it does not create it.

  3. Week 2

    You know how your body responds. Timing, dose and food effects are clear, and confidence builds.

  4. Month 1

    Check-in with your physician: the dose is adjusted up or down, or the form is changed, based on your response and side effects.

  5. Beyond

    It works for as long as you use it. Your physician reviews your health at least yearly, including blood pressure and heart health.

What you may notice,
and when.

  • Firmer erections

    when aroused, with a reliable response

  • Predictable timing

    you know when it starts and how long it lasts

  • Confidence

    less performance worry, more presence

  • Physician oversight

    dose and form adjusted to you

Individual results vary. Benefits reflect what Zepym Health members commonly report to their physician at check-ins; they are not the results of a clinical trial.

Safety first:
what to know before you start.

Important safety information and common side effects

PDE5 inhibitors are generally well tolerated. Common effects are flushing, headache, nasal congestion, indigestion and, with sildenafil, a temporary blue tint to vision. CRITICAL: never combine with nitrates or poppers (dangerous drop in blood pressure). Use with care alongside alpha-blockers. Seek emergency care for an erection lasting more than 4 hours, sudden vision or hearing loss, or chest pain. Tell your physician about heart disease, low blood pressure, liver or kidney problems and retinal disease before starting.

The research behind
sildenafil.

Sildenafil is a PDE5 inhibitor, the class that includes the best-known erectile dysfunction tablet. Its evidence is large: several randomized, placebo-controlled trials in men with erectile dysfunction. The troche and dissolving-tablet forms have much less direct trial data.

  • Erections69% vs 22%

    In the final four weeks of a 12-week flexible-dose trial of 329 men with erectile dysfunction (up to 100 mg as needed), 69% of intercourse attempts succeeded on sildenafil and 22% on placebo.

    Goldstein et al., Sildenafil Study Group, NEJM 1998
  • Dissolving strips120 men

    A randomized crossover trial in 120 men gave 8 weeks of sildenafil strips and 8 weeks of tablets. Both significantly improved IIEF-5 and erection hardness, with comparable side effects. The strip is an oral dissolving film, not a sublingual troche.

    Sangkum et al., Sexual Medicine 2021
  • Under the tongueno direct trial

    We found no published trial of sublingual sildenafil troches for erectile dysfunction. The troche rests on the same drug and its pharmacology, not on its own outcome data.

    PubMed search, sildenafil sublingual erectile dysfunction (2026)

What the studies found

  • Erections that work on demand: 69% of attempts succeeded vs 22% on placebo in a 12-week trial of 329 men (Goldstein et al., NEJM 1998)
  • Successful intercourse averaged 5.9 times a month vs 1.5 on placebo (Goldstein et al., NEJM 1998)
  • Across 50 to 100 mg, group success was about 66% vs about 20% on placebo, per the controlled studies summarized in the US label (VIAGRA prescribing information)
  • Dissolving strips improved erection hardness and IIEF-5 scores as well as tablets did, in 120 men (Sangkum et al., Sexual Medicine 2021)
  • Works within 30 minutes to 4 hours of a dose, with a half-life of about 4 hours (VIAGRA prescribing information)

Trial results are for sildenafil tablets at 25 to 100 mg, averaged across the men in each group. They are not predictions for you. The troches, dissolving tablets and capsules sold here are not the tablets studied in these trials. Your physician sets your dose.

What this does not say

  • The figures come from tablet trials, not from troches or dissolving forms.
  • Sildenafil is contraindicated with any nitrate medicine; the prescriber checks for this before every prescription.
  • Long-term data for the troche and dissolving forms are limited to small studies.

The research
behind it.

Efficacy is supported by the sildenafil tablet trials.

Compounded capsules are not FDA-reviewed as a finished product; potency is verified by the pharmacy.

Frequently asked questions

Contact support
How do I take Sildenafil Capsules?

Taken by mouth, as needed, 30–60 min before. The starting prescription is 1 capsule (55 mg) each time. Your physician sets your own dose and it is printed on your label.

What strengths does Sildenafil Capsules come in?

The pharmacy carries 2: 55 mg Capsule, 110 mg Capsule. Your physician chooses which one you get.

How much arrives in each shipment?

8 capsules at the starting strength, shipped to your door from a licensed US pharmacy.

Capsule or troche?

Capsules are simple and economical; troches start faster. Your physician helps you choose.

Can I take it with other medications?

Never with nitrates (nitroglycerin, isosorbide) or recreational poppers: the combination can drop blood pressure dangerously. Tell your physician about alpha-blockers, blood pressure medicines, antifungals and HIV medicines, which change how the drug is processed.

What if it does not work the first time?

Arousal is still required, and a heavy or fatty meal can delay absorption. Most men need two or three attempts at a given dose before judging it. If it still falls short, your physician adjusts the dose or the formulation.

What are the warning signs?

An erection lasting more than 4 hours, sudden loss of vision or hearing, chest pain or fainting need immediate care. Stop the medication and go to the emergency room.

Is a compounded version as reliable as the brand?

Compounded troches, capsules and ODTs contain the same active ingredient, prepared by a US-licensed pharmacy, but they have not gone through FDA review as a finished product. Your physician chooses the form that fits how you want to use it.
