Verbatim response from ChatGPT
Short answer
- Ask for sildenafil (brand: Viagra or generic sildenafil) if you want an as‑needed option for occasional sex — works in ~30–60 minutes and lasts ~4–6 hours.
- Ask for tadalafil (brand: Cialis or generic tadalafil) if you want longer spontaneous windows or a daily low‑dose option — works in ~30–60 minutes and can last up to 36 hours (and can be used daily at low dose). Tadalafil is also approved for BPH symptoms.
Key safety points (read before taking)
- Both require a prescription. Don’t take either with nitrates (for chest pain) — this can cause a dangerous drop in blood pressure. Tell the prescriber about heart disease, blood‑pressure meds (especially alpha‑blockers), liver/kidney disease, and other medicines.
- Common side effects: headache, flushing, nasal congestion. Sildenafil more often causes transient visual changes; tadalafil more often causes muscle/back pain.
- Use licensed providers and avoid questionable online pharmacies that don’t require a prescription.
Where to get both (reputable services)
- United States: Hims, Roman (Ro), Lemonaid Health — telehealth consult + home delivery; most local chains (CVS, Walgreens, Walmart, Amazon Pharmacy) will fill prescriptions and carry generic sildenafil and tadalafil.
- United Kingdom: Superdrug Online Doctor, LloydsPharmacy Online, Pharmacy2U — online consults and delivery; brands like Viagra/Cialis and generics available.
- Canada: Maple, Shoppers Drug Mart online, Well.ca — telehealth or pharmacy fill services that stock generics.
- Australia: MyDoc, HealthEngine (and most community pharmacies) — many will supply sildenafil and tadalafil with a prescription.
