Pair sheet · PDE5 pair

Cialis versus Viagra versus Levitra is a schedule choice, not a brand vote

Last reviewed · 9 min read · Updated

Ro-style and clinic-style pages stack the three names as if the winner were a feeling. This pair sheet stacks the prescription questions: which clock, which first milligram, which stop.

Uxora's locks stay on the dockets: tadalafil 5 mg daily and/or 20 mg PRN, sildenafil 25 mg as the first tablet, vardenafil 2.5-10 mg after a QT screen. The sheet does not rank them.

Docket card

OnsetSildenafil and vardenafil: median Tmax ~60 min fasting; tadalafil median 2 h
DurationTadalafil PRN up to 36 h vs placebo; the other two ~4-5 h clocks
FoodTadalafil unmarked; sildenafil high-fat Tmax +60 min / Cmax -29%; vardenafil Cmax -18 to -50%
AlcoholClass vasodilator add-on; tadalafil names ≥5 units for orthostasis

01Three prescriptions, three clocks

A man who types Cialis vs Viagra vs Levitra prescription into a bar is usually trying to pick one visit. He should leave with one INN. Stacking two PDE5 fills in the same week is how the class gets doubled.

Tadalafil is the only one of the three with a labeled once-daily ED board (2.5 mg starting, 5 mg if stepped up) plus an as-needed board that can sit at 20 mg. Sildenafil and vardenafil are as-needed clocks with roughly 4-hour stories.

This sheet will not tell you which tablet 'works best.' Head-to-head marketing pages do that without a chart. The dockets file the stops. Read tadalafil, sildenafil, and vardenafil before you treat a color as a decision.

Uxora does not prescribe. [email protected] is for sourcing. A licensed clinician where you live still has to write the script.

Cialis 5-20, Viagra 25, and Levitra 2.5-10 on one pair sheet

02Which intake form belongs on which molecule

If the visit is really 'I want a calendar, not a timer,' the tadalafil daily 5 mg board is the labeled tool among these three. If the visit is 'one evening, lowest first tablet,' sildenafil 25 mg is this site's first-rung lock. If the visit names amiodarone, the Levitra form may need to close before milligrams are discussed.

Walgreens-style sildenafil pages and Ro-style Cialis pages both still require a clinician. The pair sheet does not create a third shop that sells all three in one carton.

Brand names help patients recognize a box. Generic INNs are what the e-script should carry unless brand is medically required. Cheap, when it happens, is a generic window print after that script, not a reason to pick the loudest ad.

Staxyn (vardenafil ODT) and Revatio (sildenafil for PAH) are other product lines. They do not belong on a Cialis-vs-Viagra-vs-Levitra evening chart.

Pair locks versus labeled usual starts. A clinician may leave the lock. The lock is the first talk on this site.

Vardenafil (Levitra)2.5-10 mg after QT10 mg ~60 min before sext½ 4-5 h; food cuts Cmax

03How a pair sheet helps a prescriber pick one INN

Use the sheet to name the schedule in one sentence: calendar (tadalafil daily 5), first low as-needed (sildenafil 25), or short as-needed after a clean QT list (vardenafil 2.5-10). Then open that docket, not all three carts.

AUA and clinic pages often say the oral PDE5 class is similar in efficacy when doses are comparable, and that duration and food are the practical splits. This sheet agrees with that boring conclusion. It will not invent a winner percentage.

Sildalist and other export combos are not a fourth column. Two INNs in one blister still carry two nitrate bans. They are not a pair-sheet shortcut.

Portugal readers still need a prescriber licensed in their country. A US telehealth title does not become a Cedofeita fill because this pair page used the word online.

Write the schedule in one sentence on the intake: calendar, first 25 mg tablet, or short as-needed after QT. Then stop ticking boxes.

04Food and alcohol do not treat the class the same

Tadalafil may be taken without regard to food. That is the practical reason couples pick it when dinner is the event. It is not a reason to drink five units on top of a 20 mg tablet.

Sildenafil with a high-fat meal delays Tmax by about 60 minutes and drops Cmax 29%. The 25 mg first tablet is the setting where that delay ends the night. The meal memo stays on that molecule.

Vardenafil high-fat studies cut Cmax 18% to 50%. The 'fast Levitra' headline dies on a heavy plate. The onset file keeps that number next to the 2.5-10 mg range.

Alcohol is a class vasodilator add-on. Only Cialis's leaflet bothers to name 5 units as the orthostatic example. The other two still drop blood pressure with drink. Do not use a glass as a timer for any of them.

05Shared nitrate wall, different QT note

All three are contraindicated with organic nitrates and with riociguat. That wall is not negotiable because one brand felt milder in a forum.

After tadalafil, an emergency nitrate, if it is ever given, waits at least 48 hours and then only under watch. After sildenafil, the Viagra label says the safe interval is unknown. Vardenafil keeps the same class ban. Do not home-time a spray against any of them.

Vardenafil is the one with the named avoid-use line for congenital long QT and for Class IA and Class III antiarrhythmics. Sildenafil and tadalafil still need a cardiovascular history. They do not copy Levitra's QT paragraph word for word.

CYP3A4 inhibitors cut every board: tadalafil PRN to 10 mg every 72 hours and daily to 2.5 mg; sildenafil with ritonavir to 25 mg every 48 hours; vardenafil with ritonavir to 2.5 mg every 72 hours. A pair page that never mentions ritonavir is a brochure.

Pair-sheet stops that outrank a brand preference

  • Nitrates / nitrites / poppers - all three closed
  • Riociguat - all three closed
  • Ritonavir - each INN has its own cap, none stay at the marketing start
  • Class IA/III or congenital QT - vardenafil avoid; still tell the other two visits
  • Two PDE5 INNs in one week - do not

06Brand Levitra left some shelves; the INN did not

Hims-style drug pages already say brand Levitra is gone in some markets and generic vardenafil is the usual fill. That does not delete the QT paragraph. A generic 10 mg tablet still avoids Class IA and III drugs.

Brand Cialis and brand Viagra still exist as higher cash rows. The cheap search under this pair title is almost always generic tadalafil, sildenafil, or vardenafil after a real script. This sheet will not invent a brand-versus-generic dollar.

Export combos that print both sildenafil and tadalafil in one blister are not a fourth column and not a bargain version of this pair. Two INNs still carry two nitrate bans and two CYP stories.

If a portal offers 'the doctor's choice pack' with rotating INNs, treat that as a stacking risk until a clinician names one molecule for a defined period. Rotation is not a labeled schedule.

Stendra (avanafil) is a fourth oral PDE5 some comparison pages add. It is not on this site's pair lock. Do not borrow its 15-minute marketing line to justify a 20 mg Levitra first fill.

07What a first prescribed-online visit should collect for all three

Chest-pain sprays, poppers, riociguat, alpha-blockers, protease inhibitors and other CYP3A4 drugs, recent infarct or stroke, and whether sex is medically reasonable. Vardenafil adds the QT list. Sildenafil adds the meal timing if 25 mg is the first tablet. Tadalafil adds which board, daily 5 or PRN 20.

Walgreens Virtual Healthcare and Ro still describe a clinician review before a pharmacy. That sequence is the only prescribed-online meaning this sheet will use. A no-history cart is not a third option.

A cheap prescription, when it prints, prints at a licensed window after that review. Sourced US cash bands live on the three dockets. This pair page will not invent a comparison price.

Portugal readers mail [email protected] only if a card and a leaflet disagree. They do not mail a shopping list. Emergencies: 112.

08Do not stack two PDE5 fills

If a first INN failed, the next visit should say how it was taken (food, alcohol, stimulation, dose, other drugs), not add a second molecule on top of a leftover blister.

Weekend tadalafil 20 mg plus a Sunday sildenafil 25 mg is two PDE5 exposures. The memos on each docket exist so that mix-up has a file. They are not permission slips.

Sofia Mendes reviewed this sheet on 2026-08-21. She does not rank the three for a stranger and does not ship from Rua de Cedofeita 455.

Read the docket disclaimer before you change a tablet. If the remaining question is one molecule, leave this sheet and open that docket.

Docket thread

Porto-area readers asked which name to put on a first visit. Replies pick a schedule, not a winner. Reviewed 2026-08-21.

Pedro Nogueira, Cedofeita The clinic portal lets me tick Cialis, Viagra, and Levitra together. Should I?

Desk reply

Tick the schedule you actually want discussed, then let the clinician pick the INN. Ticking all three is how people get two e-scripts and take both. This pair sheet exists so you can say 'calendar' or 'first 25 mg tablet' or 'only if QT is clean' in one line. Nitrates close all three. If a spray is in the house, none of the boxes should be sent as a hopeful maybe. Ritonavir changes every board: tadalafil PRN to 10 mg every 72 hours and daily to 2.5 mg, sildenafil to 25 mg every 48 hours, vardenafil to 2.5 mg every 72 hours. Ticking all three does not dodge that. Uxora will not untick the portal. A licensed clinician will. [email protected] is not a third pharmacy.

Ana Ribeiro, Foz We eat late and we want a cheap first script. Is Viagra 25 the obvious pick?

Desk reply

It is this site's first-tablet lock, and it is a poor match for a heavy late plate because high-fat meals delay Tmax about an hour and cut Cmax 29%. A cheap 25 mg fill that misses the night is not a bargain. Tadalafil without regard to food is the labeled alternative when dinner is the event. That can be daily 5 mg or a PRN 20 mg after a review. It is not automatically cheaper. Price whatever NDC lands on the script. Vardenafil loses 18-50% of Cmax with a high-fat meal, so it is not the secret late-dinner workaround. Fasted median Tmax near an hour does not survive a steak. Ask the clinician for one INN that matches the evening you actually have, not the cheapest screenshot. Do not add a Sunday sildenafil on top of Friday tadalafil because dinner was late both nights.

Inês Barros, Lordelo Is brand Levitra gone, so I should just tick Cialis and Viagra?

Desk reply

Brand Levitra left some shelves. Generic vardenafil did not, and the QT paragraph did not. Ticking the other two names because a brand is scarce is how people skip a molecule that might still be the right short clock after QT is clean. Ask for the INN you mean. Cheap is a generic window print after one script, not a reason to tick every remaining brand.

Miguel Fonseca, Gaia I am on sotalol. Is Levitra off the list and the other two fine?

Desk reply

Levitra is avoid-use with Class III drugs, sotalol included. The other two still need a cardiovascular history and still ban nitrates. 'Fine' is a clinician's word after they have your rhythm file, not a pair-sheet blessing. Do not self-switch to tadalafil 20 mg because this paragraph named vardenafil. Open the tadalafil docket for that molecule's holds and take both cards to the visit. If sotalol exists because of a QT story, say the QT story out loud. Do not hide it to keep a cheap ED offer alive. Do not stack a leftover Levitra sample with a new Cialis script while you wait. One INN after the visit, not two while you decide.

Teresa Lopes, Boavista Can Sofia just tell me which one to request so I stop reading three dockets?

Desk reply

She can tell you what each lock means. She cannot choose your tablet from an email. Daily Cialis 5, first Viagra 25, or Levitra 2.5-10 after QT is a sentence you can take to a licensed visit. It is not a remote order. Read the disclaimer if you were about to start leftover tablets from two boxes. Last review of this sheet: 2026-08-21.
