Find Your Best ED Medication
Your Recommended Medication
When it’s time to pick an erectile dysfunction (ED) pill, the market feels like a maze. Penegra is a brand‑name tablet that packs sildenafil citrate, the same compound that powers many of the big‑name drugs. But is it the right choice for you? This guide lines up Penegra against the most common alternatives, breaks down how they work, and helps you decide which one fits your lifestyle and budget.
What is Penegra?
Penegra is marketed as an oral solution for mild to moderate ED. Its active ingredient, sildenafil citrate, relaxes blood vessels in the penis, allowing increased blood flow when sexual stimulation occurs. The standard dose is 50mg, taken about 30‑60 minutes before intimacy, with effects lasting up to 5hours.
Key points about Penegra:
- Onset: 30‑60 minutes
- Duration: 4‑5 hours
- Prescription: Required in most countries
- Typical cost (UK): £30‑£45 per tablet (brand price)
Top Oral Alternatives
The most popular oral ED meds all belong to the phosphodiesterase‑5 (PDE‑5) inhibitor class, but they differ in timing, side‑effects, and price.
Viagra (Sildenafil)
Viagra is the original sildenafil brand, launched in 1998. It shares the exact active ingredient with Penegra but is generally priced higher because of brand recognition.
Cialis (Tadalafil)
Cialis contains tadalafil, another PDE‑5 inhibitor. Its main advantage is a longer window of effectiveness - up to 36 hours - earning it the nickname “the weekend pill.”
Levitra (Vardenafil)
Levitra delivers vardenafil, which some users report feels more natural in terms of erection firmness. Onset is roughly 25‑60 minutes, with a duration of about 4‑5 hours, similar to sildenafil.
Stendra (Avanafil)
Stendra uses avanafil, the newest PDE‑5 inhibitor on the market. It promises the fastest onset - as quick as 15 minutes - but its cost is typically higher than older drugs.
Generic Sildenafil
When the brand name isn’t needed, generic sildenafil provides the same chemistry at a fraction of the price. Many pharmacies stock 25mg, 50mg, and 100mg tablets, giving you flexibility without a brand markup.
Non‑Oral Alternatives
If pills aren’t your thing, there are a few reputable non‑oral options that bypass the digestive system altogether.
Alprostadil Injection (Caverject)
Alprostadil is injected directly into the penile tissue, producing an erection within 5‑20 minutes. It’s effective for men who don’t respond to oral PDE‑5 inhibitors, but the notion of self‑injection can be a barrier for some.
Topical Creams
Compounded creams blend alprostadil with a permeation enhancer. They’re applied a few minutes before sex and avoid needles, yet insurance coverage is rare and efficacy varies.
Natural Supplements - L‑Arginine
L‑arginine is an amino acid that boosts nitric oxide production. While not as potent as prescription meds, daily doses of 2‑5g can modestly improve erections for men with mild symptoms.

Side‑Effect Profile Comparison
All PDE‑5 inhibitors share a core set of possible reactions: headache, facial flushing, nasal congestion, and upset stomach. Their frequency and intensity can shift slightly between drugs.
Side‑Effect | Penegra (Sildenafil) | Viagra (Sildenafil) | Cialis (Tadalafil) | Levitra (Vardenafil) | Stendra (Avanafil) |
---|---|---|---|---|---|
Headache | 8‑10% | 9‑11% | 4‑6% | 8‑9% | 3‑5% |
Flushing | 7‑9% | 7‑9% | 3‑5% | 6‑8% | 2‑4% |
Nasal Congestion | 4‑6% | 5‑7% | 2‑3% | 4‑5% | 1‑2% |
Vision Changes | 1‑2% | 1‑2% | 0.5‑1% | 1‑2% | 0.5‑1% |
Cost & Accessibility Snapshot
Price is often the deciding factor, especially when insurance only covers the generic version.
- Penegra: £30‑£45 per tablet (brand price)
- Viagra: £35‑£55 per tablet (brand)
- Cialis: £45‑£70 per tablet (brand); £12‑£20 for generic tadalafil
- Levitra: £40‑£60 per tablet (brand); £10‑£18 for generic vardenafil
- Stendra: £55‑£80 per tablet (brand)
- Generic sildenafil: £5‑£12 per tablet
Online pharmacies in the UK often list a 28‑day supply discount, while local NHS clinics may prescribe generic sildenafil at no charge if a GP deems it medically necessary.
Choosing the Right Option - Practical Scenarios
Below are typical user profiles and the medication that tends to work best.
- Spontaneous weekend plans - Cialis shines because its effect can last up to 36hours, so you don’t need to time the dose.
- Quick turnaround needed - Stendra’s 15‑minute onset is useful if the moment arrives unexpectedly.
- Budget‑conscious - Generic sildenafil (or Penegra if you want brand assurance) offers the lowest per‑pill cost.
- Health conditions like severe heart disease - Discuss with a doctor; some men benefit from Alprostadil injection because oral PDE‑5 inhibitors may be contraindicated.
- Preference for natural approaches - Daily L‑arginine supplements can complement lifestyle changes when ED is mild.

Safety Tips & Common Pitfalls
Regardless of the pill you pick, keep these checks in mind:
- Never combine PDE‑5 inhibitors with nitrates (often prescribed for chest pain); the combo can cause dangerous blood‑pressure drops.
- Start with the lowest effective dose. If 50mg works, there’s no need to jump to 100mg.
- Take the tablet on an empty stomach for faster absorption; heavy meals, especially fatty ones, slow it down.
- Be aware of drug‑drug interactions: certain antifungals, antibiotics, and HIV meds can raise blood levels of sildenafil and increase side‑effects.
- If you experience prolonged erection (over 4hours), seek medical help immediately - it could be priapism.
Bottom Line Summary
Penegra offers the reliability of a brand‑name sildenafil tablet without the premium price tag of Viagra. When compared side‑by‑side, the choice often hinges on timing, duration, and budget. Cialis wins for long‑lasting flexibility, Stendra for ultra‑quick onset, while generic sildenafil remains the most cost‑effective route. Non‑oral options exist for men who can’t tolerate pills.
Talk to your GP or a qualified sexual‑health specialist, consider your lifestyle, and test a single dose under medical supervision before committing to a long‑term plan.
