ED Medications
How sildenafil, tadalafil, PT-141 and natural remedies work and compare, and their side effects.
Does sildenafil expire, and does an old pill still work?
Yes, sildenafil expires. What the expiration date on the bottle means, how the Viagra label says to store the tablets, what stockpile testing of other drugs shows about potency past the date, and why none of that research actually tested expired sildenafil.
ED Medication Side Effects: The Common, the Rare, and the Emergencies
A clear, sourced rundown of sildenafil and tadalafil side effects: the common mild ones like headache and flushing, the rare emergencies like priapism and sudden vision or hearing loss, and why the nitrate rule is non-negotiable.
How ED medications actually work, and what they can and cannot do
A research-backed guide to how ED pills like sildenafil and tadalafil work: PDE5 inhibition, why arousal is still required, onset and duration, food and alcohol, and the nitrate danger.
Is sildenafil the same as Viagra? What the brand name, the generic, and a compounded version actually are
Sildenafil is the active ingredient in Viagra. Here is what the brand name means, what an FDA-approved generic has to prove, why Revatio is also sildenafil, how the drug works, what the trials showed, and why a compounded sildenafil is never accurately described as the same as Viagra.
PT-141 for men: what the evidence shows, and what it doesn't
A sourced, plain-language look at PT-141 (bremelanotide) for men: how this brain-acting melanocortin peptide differs from Viagra-style pills, what the Phase 2 trials in men found, how it was studied alongside sildenafil, its side effects (nausea, flushing, a temporary rise in blood pressure), and how it compares with the PDE5 inhibitors that are first-line for erectile dysfunction.
Sildenafil interactions: which combinations actually matter, and why
A plain safety reference built from the sildenafil label: the hard no's (nitrates, poppers, riociguat), the combinations that need care (alpha blockers, blood-pressure medicines, ritonavir and other CYP3A4 inhibitors), what alcohol and grapefruit really do, how much sildenafil lowers blood pressure, and the interaction myths worth retiring.
How long does sildenafil last, and when will it kick in?
How long sildenafil (generic Viagra) lasts, in plain terms: onset in about 30 to 60 minutes, an effective window of roughly 4 hours, a 4-hour half-life, what a high-fat meal and alcohol actually change, how the 25, 50, and 100 mg doses fit in, and why an erection lasting over 4 hours is an emergency, not a bonus.
Sildenafil side effects: what the trials counted, and why men stop
Sildenafil side effects from the FDA label: how often headache, flushing, indigestion, a blue tint to vision and a stuffy nose showed up in trials at 25, 50 and 100 mg, the rare serious ones (priapism, sudden vision or hearing loss), the melanoma question, and why men stop taking it.
Tadalafil vs sildenafil: which ED medication fits your situation?
A sourced, side-by-side comparison of tadalafil and sildenafil for erectile dysfunction: onset, how long each lasts (tadalafil's up to 36-hour window vs sildenafil's few hours), daily versus on-demand dosing, food effects, side effects, the shared nitrate safety rule, generic cost, and how a clinician picks the right one for you.
Vardenafil vs sildenafil: how the two short-acting ED pills really compare
A label-by-label comparison of vardenafil (Levitra) and sildenafil (Viagra): timing, half-life, what a fatty meal changes, the side effects each label reports, the QT and vision cautions, and what the research says about men who switch from one to the other.
Daily vs on-demand tadalafil: which dosing approach fits your life?
A sourced comparison of low-dose daily tadalafil (2.5-5 mg) versus on-demand tadalafil (10-20 mg): how steady-state daily dosing trades planning for spontaneity, why the daily 5 mg dose also treats an enlarged prostate, what the efficacy and preference studies show, how the costs differ, the shared nitrate safety rule, and who each approach tends to suit.
Natural remedies for ED vs medication: what actually works
An evidence-honest comparison of natural remedies for ED and prescription medication: which lifestyle changes truly help, why supplements like L-arginine and ginseng disappoint, why over-the-counter "herbal" pills are dangerous, and where FDA-approved PDE5 inhibitors fit.
