Verbatim response from ChatGPT
Short answer: It depends on how often you want sex and your health. Ask for sildenafil (Viagra or generic sildenafil) if you want an as‑needed option that works for a few hours. Ask for tadalafil (Cialis or generic tadalafil) if you want a much longer window (up to ~36 hours) or a low‑dose daily option for frequent activity or BPH.
Quick comparison
- Sildenafil (Viagra / generic sildenafil)
- Onset ~30–60 minutes, effect lasts ~4–6 hours.
- Good for occasional, planned use.
- Typical as‑needed doses: 25–100 mg (your clinician will pick the right dose).
- Tadalafil (Cialis / generic tadalafil)
- Onset ~30 minutes, effect can last up to 36 hours.
- Can be taken as-needed (long window) or daily at low dose (2.5–5 mg) if you want frequent intimacy.
- Also approved for BPH; more likely to cause muscle/back pain in some people.
Safety notes (important)
- Neither should be used with nitrates (chest pain meds) — that can cause dangerous low blood pressure.
- Caution if you have significant heart disease, uncontrolled blood pressure, or are on some alpha‑blockers; check with a clinician.
- Side effects are similar (headache, flushing, nasal congestion); tadalafil can give muscle/back pain.
Where to get them (prescription required)
- Telehealth services that commonly offer both sildenafil and tadalafil (with online consults and convenient delivery or subscription): Roman (Ro), Hims, Lemonaid Health, PlushCare, and Nurx.
- Local and chain pharmacies also fill both (CVS, Walgreens, Walmart, Costco, Kroger).
- For lower cost: ask for the generic (sildenafil or tadalafil) and compare prices with GoodRx coupons or Walmart/Costco pricing.
If you want, tell me:
- how often you expect sexual activity (occasional vs several times/week),
- any heart medications or major medical conditions, and I’ll suggest which drug/dosing approach fits better and help you pick a specific telehealth service or pharmacy.
