When you’re dealing with erectile dysfunction, finding the right treatment isn’t just about price or convenience-it’s about what actually works for your body. Viagra capsules, which contain sildenafil citrate, have been the go-to for decades. But they’re not the only option anymore. Many men are now asking: Are there better, cheaper, or longer-lasting alternatives? The answer isn’t one-size-fits-all. It depends on your health, lifestyle, and what side effects you can tolerate.
What Are Viagra Capsules Really Doing?
Viagra capsules contain sildenafil a phosphodiesterase type 5 (PDE5) inhibitor that increases blood flow to the penis during sexual stimulation. It’s not an aphrodisiac-you still need arousal for it to work. Most men feel effects within 30 to 60 minutes, and the drug lasts about 4 to 5 hours. The standard dose is 50 mg, but doctors often start with 25 mg or go up to 100 mg based on response and tolerance.
Viagra works for about 70% of men with ED, but it doesn’t work for everyone. Some people can’t take it because of heart conditions, low blood pressure, or interactions with nitrates. Others just don’t like the side effects: headaches, flushing, upset stomach, or blurred vision. That’s where alternatives come in.
Cialis (Tadalafil): The Long-Lasting Option
If you want flexibility, Cialis a brand name for tadalafil, another PDE5 inhibitor with a much longer half-life might be your best bet. While Viagra lasts 4-5 hours, Cialis can work for up to 36 hours-hence the nickname "the weekend pill."
That means you don’t have to plan sex around taking a pill. One dose in the morning could still be effective by Sunday night. Cialis also comes in a daily 2.5 mg or 5 mg version, which keeps a steady level in your system. This is ideal for men who have sex more than twice a week or want to avoid thinking about timing altogether.
Side effects are similar to Viagra but with less flushing and nasal congestion. However, Cialis can cause back pain or muscle aches in about 5% of users, usually 12-24 hours after taking it. That’s not common, but it’s something to watch for.
Levitra (Vardenafil): Faster and Stronger?
Levitra the brand name for vardenafil, another PDE5 inhibitor with a slightly faster onset than sildenafil hits the bloodstream quicker-sometimes in as little as 25 minutes. It’s also more potent by weight, meaning a 10 mg dose of Levitra can be as effective as a 50 mg dose of Viagra.
Levitra might be a better fit if you have diabetes or after prostate surgery, where studies show slightly better success rates than sildenafil. It’s also less affected by food, so you don’t need to wait hours after eating. The downside? It still only lasts 4-5 hours, same as Viagra. And it’s not available as a daily option.
Side effects include headaches, dizziness, and stuffy nose. Rarely, it can cause sudden vision loss (non-arteritic anterior ischemic optic neuropathy), though this is extremely uncommon.
Generic Sildenafil: The Budget-Friendly Choice
Viagra is expensive-often £50-£70 per pill in the UK without insurance. But generic sildenafil the same active ingredient as Viagra, sold under dozens of brand names like Silagra, Caverta, or Sildenafil Citrate costs as little as £2-£5 per tablet. It’s identical in chemical structure, dosage, and effect.
Many men switch to generic versions without noticing any difference. The only variations are in fillers, coatings, or shape. Some generics come in lower doses (25 mg) that let you titrate more precisely. Others are available as chewable tablets or oral strips for faster absorption.
Buying generic online can be risky. Stick to UK-registered pharmacies. The NHS prescribes generic sildenafil routinely, so it’s safe if you get it through legitimate channels.
Stendra (Avanafil): The New Kid on the Block
Stendra the brand name for avanafil, the newest PDE5 inhibitor approved in the UK is designed to act faster than any other. It can start working in as little as 15 minutes. That’s ideal for men who want spontaneity.
It’s also less likely to cause visual disturbances or nasal congestion compared to sildenafil or vardenafil. Doses range from 50 mg to 200 mg, and it lasts 4-6 hours. It’s more expensive than generic sildenafil but often cheaper than branded Cialis or Levitra.
Stendra is not yet widely available on the NHS, so most people pay out-of-pocket. But for those who’ve tried other options and had side effects, it’s a promising alternative.
Other Options: Beyond Pills
Not everyone wants to swallow a pill. If oral meds aren’t working-or you’re looking for something different-there are other paths:
- Intracavernosal injections (like Caverject or Alprostadil): Injected directly into the penis, these work in 5-10 minutes and last up to an hour. Highly effective, but the idea of needles scares many men.
- Urethral suppositories (MUSE): A tiny pellet inserted into the urethra. Works in 10-20 minutes, but can cause mild pain or urethral burning.
- Penile pumps: A vacuum device that draws blood into the penis, then a ring holds it there. No drugs, no prescriptions. But it’s mechanical and not as natural-feeling.
- Testosterone therapy: Only helps if low testosterone is the root cause. Most men with ED have normal levels, so this isn’t a universal fix.
Which One Should You Choose?
There’s no single "best" ED medication. Here’s how to decide:
| Medication | Active Ingredient | Onset Time | Duration | Daily Option? | Food Impact | Typical UK Price (per tablet) |
|---|---|---|---|---|---|---|
| Viagra | Sildenafil | 30-60 min | 4-5 hours | No | High-fat meals delay it | £50-£70 |
| Cialis | Tadalafil | 30 min | 36 hours | Yes (2.5-5 mg) | Minimal | £40-£80 |
| Levitra | Vardenafil | 25-60 min | 4-5 hours | No | Low impact | £45-£75 |
| Generic Sildenafil | Sildenafil | 30-60 min | 4-5 hours | No | High-fat meals delay it | £2-£5 |
| Stendra | Avanafil | 15-30 min | 4-6 hours | No | Minimal | £50-£90 |
If you want spontaneity → Stendra or Cialis daily.
If you want the longest window → Cialis (36-hour version).
If you’re budget-conscious → Generic sildenafil.
If you have diabetes or post-surgery ED → Levitra or Stendra may work better.
If you hate side effects → Try lower doses first. Start with 25 mg of sildenafil or 5 mg of Cialis.
What Doesn’t Work (And Why)
Many men try herbal supplements like horny goat weed, ginseng, or L-arginine. These are not FDA or MHRA-approved. There’s no solid evidence they work for ED. Some contain hidden PDE5 inhibitors-like sildenafil or tadalafil-without listing them. That’s dangerous. You might end up with a dangerous interaction or overdose.
Don’t mix ED meds with nitrates (used for chest pain), alpha-blockers (for high blood pressure or prostate), or recreational drugs like poppers. These combinations can cause life-threatening drops in blood pressure.
Also, ED meds won’t fix performance anxiety or relationship issues. If stress or depression is the root cause, therapy or antidepressants might help more than a pill.
When to Talk to Your Doctor
You don’t need a prescription for generic sildenafil in the UK if you buy it from a registered pharmacy after a simple online consultation. But if you’re over 50, have heart disease, high blood pressure, liver or kidney issues, or take other medications-you should talk to your GP or a men’s health specialist first.
ED can be an early warning sign of heart disease, diabetes, or blocked arteries. If you’ve never been screened for these, now’s the time.
Your doctor can help you pick the right option based on your medical history-not just price or ads you’ve seen online.
Can I take Viagra and Cialis together?
No. Never combine different PDE5 inhibitors like Viagra, Cialis, Levitra, or Stendra. They all work the same way and can cause dangerously low blood pressure, dizziness, fainting, or heart problems. Stick to one at a time.
Is generic sildenafil as good as Viagra?
Yes. Generic sildenafil contains the exact same active ingredient as Viagra. The only differences are in the inactive fillers, color, or shape. Many men switch without noticing any change in effectiveness. The NHS prescribes generic sildenafil routinely because it’s proven safe and effective.
How long does sildenafil last in the body?
Sildenafil’s effects last about 4 to 5 hours, but it can take up to 24 hours to fully leave your system. The half-life is around 4 hours, meaning half the drug is gone after that time. You shouldn’t take another dose within 24 hours.
Can I drink alcohol with sildenafil?
Moderate alcohol (one or two drinks) is usually fine, but heavy drinking can reduce effectiveness and increase side effects like dizziness or low blood pressure. Avoid binge drinking or mixing with other sedatives.
Do ED pills work for everyone?
No. About 30% of men don’t respond to PDE5 inhibitors. This can be due to nerve damage from diabetes, prostate surgery, severe vascular disease, or psychological factors. If pills don’t work, talk to your doctor about injections, pumps, or therapy.
Final Thoughts
Viagra capsules put sildenafil on the map-but they’re just one tool in a much bigger toolbox. Whether you need something fast, long-lasting, cheap, or gentle on your body, there’s an option that fits. The key is matching the drug to your life, not the other way around.
Don’t just pick the cheapest or the most advertised. Talk to a professional. Try one at a time. Keep track of what works and what doesn’t. And remember: ED is treatable. You’re not alone-and you don’t have to settle for less than what works for you.
