The start tablet and the title tablet are not the same night
A man who never tried 50 mg should not learn his nitrate history on a 100 mg first swallow. The labelled path for most patients is 50 mg, then up or down.
Yvessa still writes 100 mg in the uses title. That is a SERP lock and a ceiling reminder, not a claim that 50 mg vanished from the SmPC.
If 50 mg worked and only dinner made it late, stay on 50 and fix the meal. The after-dinner note covers that failure mode.
Sildenafil plus tadalafil strips are not a uses option here
Internet super blisters that pair two PDE5 inhibitors ignore every once-daily and class-single rule on this desk. The 100 mg lock is sildenafil alone.
A pharmacy generic 100 mg tablet with a batch number beats a mystery combo from a banner ad. Yvessa will not price or route those strips.
If a man already took a combo strip, treat it as stacked PDE5 exposure and do not add a labelled 100 mg the same day. Seek care for chest pain or an erection past four hours. Name the strip at emergency triage so nobody assumes a single labelled 100 mg was the only exposure.
Who actually needs the ceiling
Step up when 50 mg is tolerated - flushing and headache manageable - but erections stay inadequate on a fair fasted or light-meal trial. Do not step up because a friend brags about 100 mg.
Once-daily maximum still holds. Two 50 mg tablets the same night are already the ceiling if they are sildenafil 50s. Do not add a third.
PDE6 colour tinge and dyspepsia can worsen at 100 mg. That is a reason to stay at 50, not a reason to switch brands in the same evening.
| Rung | Typical reason | Yvessa title? |
|---|---|---|
| 25 mg | AE, age/hepatic/renal flags, strong CYP3A4 inhibitors | No - step-down |
| 50 mg | Usual labelled start | No - start, not the lock |
| 100 mg | Ceiling after a fair 50 mg trial | Yes - uses lock |
Write the conditions or the 50 mg trial did not happen
Note the meal, the alcohol, the time to attempt, and whether stimulation was present. Four fondue nights are one data point repeated.
If 50 mg worked twice and failed twice, look at the failed nights before you climb. The ceiling will inherit the same meal mistake.
Bring that scrap of paper to clinic. 'It does not work' is not a titration history. Yvessa will not titrate from a one-line email. If the scrap of paper never gets written, assume the trial was not fair and do not climb.
When the labelled start is already 25 mg
Cirrhosis and severe renal impairment raise sildenafil levels. Many labels push those men to 25 mg to start. The Yvessa 100 mg title does not cancel those rows. A 'uses lock' is a SERP sentence, not a one-size first box.
Age alone is not a number on the label the way Child-Pugh is, but older men collect interacting drugs. Audit the list before you gift a 100 mg sample.
Grapefruit is a softer CYP3A4 bump than ritonavir. Mention it. Do not treat it as equal to a contraindicated nitrate.
Colour tinge versus a reason to stop the 100 mg lock
Transient blue-tinge or brightness change is a known PDE6-adjacent effect and can be more noticeable at 100 mg. It is usually short. Sudden monocular vision loss is NAION-until-proven-otherwise: stop the drug and get urgent care.
A man who cannot tolerate the tinge at 100 mg may still do well at 50 mg. That is a step-down, not a class failure.
Hearing drop or tinnitus after a dose is another stop-and-call signal. Do not wait to 'see if 100 mg works better tomorrow'.
Ceiling uses that still fail for non-dose reasons
Venous leak, poorly controlled diabetes, heavy smoking, and untreated sleep apnoea can fail 100 mg on a perfect empty stomach. Climbing past the label is not a uses option on this desk.
Peyronie's pain and partner penetration pain are structural or gynaecology problems. Extra sildenafil does not straighten a plaque.
If 100 mg fails cleanly, write that down and take it to clinic. Collecting vardenafil 10 mg and tadalafil 5 mg in the same week without a gap is how stacked PDE5 exposure happens.
25 mg is a real labelled uses rung
Strong CYP3A4 inhibition - ritonavir is the extreme case - can multiply sildenafil AUC. Many labels start those men at 25 mg and widen the interval. Copying a healthy volunteer's 100 mg dinner onto that chart is how hypotension shows up.
Older men and those with cirrhosis or severe renal impairment often start lower. The parent plan has the rows. This note only refuses the myth that 25 mg is a fake starter invented by pharmacies.
Revatio 20 mg three times daily is PAH. It is not an ED 25 mg cousin you can freely interchange.
Tamsulosin nights and the 100 mg title
Alpha-blockers plus any PDE5 can drop standing blood pressure. The usual counsel is a stable blocker dose and a low PDE5 start - often 25 mg sildenafil - not a first-night 100 mg because this site locked the ceiling.
Volume depletion, extra antihypertensives, and alcohol make the pairing worse. A 'fair trial' of 50 mg is not fair if the man stood up into a black-star evening and blamed the milligram.
Do not stop the alpha-blocker on your own to 'make room' for 100 mg. That is a urology conversation, not a markup permission.
What counts as a fair 50 mg trial before you climb
At least a few attempts with stimulation, without a high-fat meal, without binge alcohol, and without a hidden nitrate. One fondue night is not a trial.
Anxiety can fail every milligram. Adding 50 mg more will not fix a fight that started in the hallway.
If 50 mg fails cleanly, the prescriber may go to 100 mg or may leave the class. Daily tadalafil 5 mg is a different clock. Vardenafil 10 mg is a different QT conversation. See the overlay before you collect bottles.
Ladder rules under the 100 mg title
- 50 mg start for most; 100 mg only after a fair trial or a clinician choice
- 25 mg when the label or the interacting drug says so
- Never two PDE5 agents the same day
- Nitrates close 25, 50, and 100 alike
A 100 mg sample is not a start rung
Clinic samples are often the ceiling tablet because that is what sits in the cupboard. If the man has never tried 50 mg, say so before he leaves with 100 mg in a paper bag.
Yvessa locked 100 mg as the uses title. The first supervised night can still be 50 mg. Those two facts live together on this overlay.
A leftover sample from a friend is an unlabelled strip. Do not treat it as the Yvessa lock.
Title the ceiling, prescribe the start
Keep the sildenafil plan as the uses sheet. This overlay only says why 100 mg is the lock while 50 mg remains the usual first rung.
Emergency symptoms - chest pain, priapism past four hours, sudden vision loss - go to 144, not to a higher tablet. The 100 mg uses lock is a ceiling sentence. The first night can still be the labelled 50 mg start. Write the meal and stimulation conditions down so the next visit is a real titration.
