Generic sildenafil is the same drug everywhere it's legally sold in the U.S.: sildenafil citrate, manufactured to FDA standards, bioequivalent to Viagra. What changes is the price, and it changes a lot. This comparison lays out per-dose sildenafil pricing by strength at the two providers we track most closely, converts it into monthly totals at real usage levels, and explains why the numbers differ. All pricing was verified from published sources in September 2026.
Per-Dose Pricing by Strength
| Strength | Roman (subscription) | PeterMD (fixed packs) | Brand Viagra (reference) |
|---|---|---|---|
| 25mg | ~$4/dose | Not offered | — |
| 50mg | ~$6/dose | Not offered | Up to ~$70/pill |
| 100mg | ~$10/dose | $6.00–$6.25/tab | Up to ~$70/pill |
The pattern is clear. Roman is cheaper at the lower strengths — PeterMD doesn't offer them at all — while PeterMD is meaningfully cheaper at 100mg. The 100mg gap is the interesting one: same drug, same strength, ~$10 versus ~$6.
Monthly Cost at Real Usage Levels
Per-dose pricing only becomes meaningful once you multiply it by how often you'll use it. Most men fall somewhere between one and three doses a week.
| Option | 4 doses/mo | 8 doses/mo | 12 doses/mo |
|---|---|---|---|
| Roman 25mg (~$4) | ~$16 | ~$32 | ~$48 |
| Roman 50mg (~$6) | ~$24 | ~$48 | ~$72 |
| Roman 100mg (~$10) | ~$40 | ~$80 | ~$120 |
| PeterMD 100mg (~$6.25) | ~$25 | ~$50 | ~$75 |
| Brand Viagra (~$70) | ~$280 | ~$560 | ~$840 |
Two things jump out. First, brand-name Viagra at 8 doses a month costs more than a year's worth of Roman's 25mg sildenafil at the same frequency. Second, the choice between Roman 50mg and PeterMD 100mg is nearly a wash on price, which means it should be decided by what your clinician prescribes and which buying model you prefer, not by the number on the table.
Why the Same Pill Costs Different Amounts
Strength tiers are a pricing strategy
Manufacturing a 100mg tablet doesn't cost 2.5x what a 25mg tablet does. Telehealth providers tier by strength because it's a straightforward way to segment customers, and because the higher strengths are what more men end up on. We go deep on this in Why is 100mg sildenafil so much more expensive?
Bundled services
Roman's price includes a video visit with a licensed clinician, a blood pressure review, ongoing messaging and free shipping. PeterMD's leaner intake skips the video visit. That difference in overhead shows up in the 100mg price gap.
Subscription vs pack economics
Subscription platforms count on retention and price accordingly, with the lowest per-dose rates at higher commitment. Fixed-pack sellers make their margin on each transaction with no assumption you'll return, which tends to produce simpler, flatter pricing.
Pack size
PeterMD's per-tablet price drops slightly as pack size rises, from ~$6.25 in a 10-pack to ~$6.00 in the larger packs. That's a modest discount for buying more at once; only take it if you'll use the tablets before expiry.

When generic sildenafil first entered the U.S. market in late 2017, retail pharmacy prices varied enormously and many men still paid brand prices out of habit. The direct-to-consumer telehealth model changed that by publishing per-dose rates and bundling the prescription. Today the competitive pressure runs in two directions at once: subscription providers like Roman compete on included services and lower-strength pricing, while fixed-pack sellers like PeterMD compete on transparency and a flat 100mg price. For buyers, the practical result is that the legitimate market has converged on a ~$4–$10 band, and the main way to overpay is to buy brand or to buy the wrong strength from the wrong model.
What we expect to change
Prices in this article are accurate as of September 2026 and we re-verify them regularly. The things most likely to move are Roman's plan-commitment thresholds for the lowest rates and PeterMD's pack sizes. The strength-tier structure at subscription providers has been stable for years and is unlikely to flatten, because it's a deliberate pricing choice rather than a cost artifact.
Reading the Fine Print
Provider pricing pages are designed to lead with the lowest number. Before you compare, check:
- Which strength the headline price applies to. "From $4" almost always means 25mg.
- Whether the rate requires a quantity or plan commitment. The lowest per-dose rate is often tied to a larger monthly quantity or a multi-month plan.
- Shipping. Roman includes it. Others may add it at checkout.
- Renewal terms. Subscriptions renew until you change them. Fixed packs don't.
- Evaluation fees. Some providers charge separately for the consult. Roman's evaluation is included; PeterMD's prices are public and all-in for the pack.
Sildenafil Price vs Tadalafil Price
Sildenafil is the cheaper drug per dose, but it works for roughly 4–6 hours. Tadalafil, at $6.33–$7.25 per tablet at PeterMD or from ~$8 at Roman, works for up to 36 hours. For a man whose typical use is a full weekend, one tadalafil dose can do the job of two or three sildenafil doses, and the "more expensive" drug ends up cheaper per month. See Tadalafil vs Sildenafil: Which Generic Is Cheaper Per Month? for that math.
Quick Decision Guide
- New to ED medication, no diagnosis yet: Roman. The video evaluation sets your strength properly and the 25mg/50mg pricing is the lowest we track.
- Already prescribed 100mg, want the lowest price: PeterMD's fixed packs at ~$6/tab.
- Already prescribed 100mg, want daily formats or Ro Sparks too: Roman, and accept the ~$10 rate or ask your clinician whether 50mg is sufficient.
- Irregular use, hate subscriptions: PeterMD.
- Want it fully handled with free shipping and clinician messaging: Roman.
Whichever you choose, use HSA/FSA funds if you have them; prescription sildenafil is generally eligible and it's a 20–35% effective discount. Details in our HSA/FSA guide.
What About Sildenafil Cheaper Than This?
Our Verdict — September 2026
For 25mg or 50mg sildenafil, Roman is the best value we track, with per-dose pricing at or below anything comparable and a genuine clinical evaluation included. For 100mg sildenafil, PeterMD's fixed packs at ~$6/tab are the cheaper route, particularly if you want to avoid a subscription. Let your clinician set the strength first; then pick the provider that prices that strength best.
Frequently Asked Questions
How much does generic sildenafil cost in 2026?
Through licensed U.S. telehealth providers, generic sildenafil costs roughly $4 to $10 per dose depending on strength and provider. Roman lists 25mg at ~$4, 50mg at ~$6 and 100mg at ~$10; PeterMD's 100mg fixed packs work out to ~$6.00–$6.25 per tablet.
Is 50mg or 100mg sildenafil better value?
Per milligram, 100mg is cheaper. Per dose, 50mg is cheaper. The right answer is the lowest strength that works for you, which your clinician should help determine. Don't pick a strength for price reasons.
Why is generic sildenafil priced per dose instead of per bottle?
Telehealth providers price per dose because prescriptions are typically written for a number of doses per month. Fixed-pack sellers like PeterMD price per pack of 10–30 tablets, which works out to a per-tablet rate.
Does generic sildenafil work as well as Viagra?
Yes. FDA-approved generics must demonstrate bioequivalence to the brand product. The active ingredient, sildenafil citrate, is identical; only the inactive ingredients and price differ.
Can I split 100mg sildenafil tablets to save money?
Some clinicians approve splitting scored tablets, which can lower the effective per-dose cost. This is a decision for your prescriber; don't assume it without asking, and be aware that unscored tablets split unevenly.
What's the cheapest sildenafil strength?
25mg is the cheapest per dose at Roman (~$4). It's also the lowest standard strength and won't be sufficient for everyone; many men start at 50mg.
Are sildenafil prices the same in every state?
Provider pricing is generally national, but availability varies. PeterMD lists service in 48 states, and Roman's clinician availability depends on state licensing. You'll see eligibility during sign-up.
