Viagra in NZ (2026): Do You Need a Prescription, What Sildenafil Costs, and How to Get It
Based on the clinical experience of Dr Mark Morunga, NZ-registered doctor and Magna Clinical Lead · Updated November 2026
Viagra is a prescription medicine in New Zealand, with one exception most men don't know about: a trained pharmacist can supply sildenafil, the medicine in Viagra, without a prescription to men aged 35 to 70. Outside that window you need a doctor, which can be your GP or an online one. It isn't funded for erectile dysfunction, so everyone pays, but the generic is cheap: a few dollars a tablet. The part that costs money, and the part that keeps it safe, is the check that it's right for you. Here's how each route works, what you'll actually pay in 2026, and how to avoid the fakes.
Viagra, sildenafil, Vedafil and Silvasta: what's the difference?
Sildenafil is the medicine. Viagra is the original brand, and it's still sold here. Vedafil and Silvasta are the generic brands New Zealand pharmacies stock most often. All of them contain the same active ingredient, and Medsafe only approves a generic once it has been shown to deliver the same amount of medicine into the bloodstream as the original. The differences are the name on the box, the look of the tablet and the price.
So when men search for Viagra in NZ, what they're usually given, and what works just as well, is sildenafil. Healthify has a plain-language summary, and Medsafe publishes the full consumer medicine information.
Do you need a prescription for Viagra in NZ?
Usually, yes. Sildenafil is classified as a prescription medicine, except when it's supplied by a pharmacist who has completed approved training, to a man aged 35 to 70 with erectile dysfunction. That exception has been in place since 2014, and New Zealand was among the first countries to allow it. It gives Kiwi men three legitimate routes.
| Route | Who it's open to | Prescription needed? | What you can get | Typical cost |
|---|---|---|---|---|
| Your GP | Any adult man the doctor assesses as suitable | Yes | Sildenafil or tadalafil | $45–80 for the appointment, plus the tablets |
| A trained pharmacist | Men aged 35 to 70 only, after a screening consult | No | Sildenafil only | Consult free to $35, plus about $6–10 a tablet |
| An online doctor (such as Magna) | Any adult man the doctor assesses as suitable | Yes, issued online | Sildenafil or tadalafil | From $39 a month, everything included |
Can you buy Viagra over the counter?
Not off the shelf. What you can do, if you're between 35 and 70, is have a consultation with a pharmacist who has done the erectile dysfunction training. It happens in a private room and takes about 20 minutes the first time. The pharmacist checks your blood pressure, goes through your medical history and your medications, and if nothing rules you out, sells you a small pack of sildenafil there and then. The consult has to be repeated every 12 months.It's quick, and for a healthy man in the age range it works well. The limits are worth knowing before you walk in:
- Under 35 or over 70, the pharmacist can't supply it and has to refer you to a doctor.
- Sildenafil only. If tadalafil would suit you better, that needs a prescription.
- Any flag sends you to a doctor anyway: heart disease, chest pain, blood pressure outside the safe range, nitrate medicines, and some eye and liver conditions.
- Not every pharmacy offers it. Ring first and ask whether a trained pharmacist is on that day.
What Viagra and sildenafil cost in NZ
| What you're buying | Typical price (November 2026) | Notes |
|---|---|---|
| Generic sildenafil (Vedafil), on prescription | About $9–10 for four tablets | The cheapest way to buy the medicine itself |
| Silvasta, on prescription | About $14 for four tablets | New Zealand-made generic |
| Viagra brand, on prescription | About $14–20 for four tablets, about $50 for twelve | Same medicine, original brand |
| Pharmacist supply, no prescription | Consult free to $35 once a year, then about $6–10 a tablet | Men aged 35 to 70 only |
| GP appointment | $45–80 each time | Then pharmacy prices as above |
| Online doctor (Magna) | From $39 a month on a three-month plan | Doctor assessment, prescription, medicine, delivery and follow-ups included |
Prices are taken from New Zealand pharmacy websites and vary by pharmacy and strength, so treat them as a guide.
Two things stand out. The tablets themselves are cheap, and what you're really paying for is access. If you already have a GP you're comfortable raising this with, a script for generic sildenafil filled at a discount pharmacy is the lowest-cost way to do it. What men pay for with the pharmacist and online routes is not having to book the appointment and say it out loud, and with an online service, having the follow-up built in: someone to adjust the dose if the first one isn't right, or switch you to the other tablet if it suits you better. The men who have been putting off the GP visit for a couple of years are who those routes are for.
Is Viagra funded in NZ?
Not for erectile dysfunction in general. Pharmac funds sildenafil under Special Authority for pulmonary arterial hypertension, Raynaud's phenomenon, and erectile dysfunction caused by a spinal cord injury. Everyone else pays the full price, whichever route they use.
One 2026 wrinkle: according to Pharmac's supply notice, the two lower strengths of Vedafil have been in short supply since mid-2026 because of a manufacturing problem, and pharmacies were asked to keep that stock for funded patients. If you're paying privately you may be offered another brand or a different pack. Pharmac hasn't given a firm date for normal supply, so check the notice or ask your pharmacist.
How to take sildenafil, and what to expect
Take it about an hour before sex. It can start working in as little as half an hour, and it keeps working for about four hours. It doesn't cause an erection on its own. It works when you're aroused, by relaxing the blood vessels in the penis so more blood flows in and stays there, and it won't raise your sex drive.
Two things blunt it: a heavy or fatty meal, which slows it down, and more than a drink or two.
It works for about seven in ten men. The commonest reason it "doesn't work" is giving up too early, after a first attempt taken too late, on a full stomach, on a nervous night. Give it six to eight properly timed tries before you judge it, and tell your prescriber how it went, because the dose can be adjusted. Never take more than one dose in 24 hours.
Side effects, and who shouldn't take it
The common ones are a headache, a flushed face, a blocked nose, indigestion, and sometimes a temporary blue tinge to your vision or sensitivity to light. They're usually mild and pass within a few hours.The serious risks are specific and avoidable:
- Never with nitrates or poppers. GTN spray, tablets or patches, isosorbide and nicorandil are used for angina, and amyl nitrite is a nitrate too. Combined with sildenafil they can drop your blood pressure dangerously.
- Get a doctor's assessment first if you've had a recent heart attack or stroke, have unstable angina, severe heart failure, very low blood pressure, severe liver or kidney disease, or have lost vision from the optic nerve condition NAION.
- Tell the prescriber about alpha blockers for your prostate or blood pressure, and about antifungal or HIV medicines, because the dose may need to change.
- Get urgent help for an erection lasting more than four hours, sudden loss of vision or hearing, or chest pain during sex. If you see a doctor for chest pain, tell them you've taken sildenafil.
One more thing a good prescriber will raise. Erectile dysfunction can be an early sign of changes in your blood vessels, sometimes years before any heart symptoms. If you're over 40 and it has crept up gradually, get your blood pressure, cholesterol and blood sugar checked as well.
Viagra vs Cialis: which suits you?
Sildenafil isn't the only option, and for some men it isn't the best one. Tadalafil, the medicine in Cialis, works the same way on a very different clock.
| Sildenafil (Viagra) | Tadalafil (Cialis) | |
|---|---|---|
| When you take it | About an hour before sex | At least 30 minutes before, or once a day at a low dose |
| How long it lasts | About 4 hours | Up to 36 hours |
| Food | A heavy meal slows it down | Not affected |
| From a pharmacist without a prescription | Yes, men aged 35 to 70 | No |
| Suits | A planned night | Spontaneity, a weekend away, or men who want nothing to time |
Neither is stronger; they work for about the same share of men. The choice is about how you have sex. If you're looking for Viagra alternatives because sildenafil gave you side effects or the timing never suited, tadalafil is the usual next step, and plenty of men switch. Our erectile dysfunction treatment guide covers every option, including the ones that aren't tablets.
Buying Viagra online in NZ: what's legal and what isn't
There are two legal ways to get it online. A New Zealand online pharmacy can fill a prescription from a New Zealand prescriber and courier it to you. Or a New Zealand online doctor service can do the whole thing: a doctor registered here assesses you, writes the prescription, and a New Zealand pharmacy dispenses it.
What isn't legal is ordering from an overseas website that ships without a New Zealand prescription. Parcels are stopped at the border all the time. In Medsafe's 2018 international enforcement operation, erectile dysfunction medicines were the most commonly detained medicines, with close to 125,000 dose units held that year. The bigger problem is what gets through. When Medsafe has tested seized products, it has found tablets with the wrong medicine, the wrong amount, or no active ingredient at all. When sildenafil was reclassified in 2014, it was kept in the prescription class rather than made a pharmacy medicine outright, partly so that Medsafe's enforcement team could keep intercepting it.
A quick test for any website: does it name a New Zealand-registered doctor, does it ask real questions about your health and medications, and is the medicine dispensed by a New Zealand pharmacy? If the answer to any of those is no, close the tab. If you're comparing services, see our guide to Hims alternatives in NZ.
Getting sildenafil through Magna
With Magna you complete a short online assessment, a New Zealand-registered doctor reviews it, and you have a call with a Magna team member to go through the plan. If treatment is right for you it's prescribed, made up by a New Zealand pharmacy and delivered free in plain packaging. The on-demand plan starts from $39 a month, with dose changes, follow-ups and switching between options included, and you can pause or cancel any time.
A few things to be straight about. Magna's doctors prescribe sildenafil, the medicine, not Viagra-branded tablets. The doctor decides what's prescribed, not the questionnaire, and that may be tadalafil if it fits how you have sex. And if the assessment turns up something that needs a GP or a specialist, you'll be told.
Assessments are reviewed under clinical lead Dr Mark Morunga, founder of Essential Men's Clinic in Auckland, who holds a Certificate in Andrology and has treated thousands of men's health patients across New Zealand.
If finishing too early is part of the picture as well, the two are often treated together. See our guide to premature ejaculation treatment in NZ.
Viagra in NZ: FAQs
Can you buy Viagra over the counter in NZ?
Not off the shelf. Men aged 35 to 70 can be supplied sildenafil, the medicine in Viagra, by a trained pharmacist without a prescription after a private screening consultation. Everyone else needs a prescription from a doctor.
Do I need a prescription for sildenafil in NZ?
Yes, unless you're 35 to 70 and use the pharmacist route. A prescription can come from your GP or from a New Zealand-registered doctor through an online service.
How much is Viagra in NZ?
On prescription, about $14 to $20 for four Viagra-brand tablets, and about $9 to $10 for four generic sildenafil tablets. A pharmacist consult adds up to $35 once a year, and a GP appointment $45 to $80. Online doctor plans start from $39 a month with everything included.
Is Viagra funded in NZ?
Not for erectile dysfunction in general. Sildenafil is only funded under Special Authority for pulmonary arterial hypertension, Raynaud's phenomenon, and erectile dysfunction caused by a spinal cord injury.
Can I get Viagra if I'm under 35?
Not from a pharmacist without a prescription, but a doctor can prescribe it if you've been assessed and it's appropriate. In younger men, erectile dysfunction is more often driven by anxiety, alcohol or sleep than by blood vessels, and the tablets usually work well.
Is generic sildenafil as good as Viagra?
Yes. It's the same active ingredient, and Medsafe requires generics to perform the same way in the body as the original. The difference is the brand name and the price.
Can I buy Viagra online in NZ?
Yes, legally, in two ways: from a New Zealand online pharmacy with a New Zealand prescription, or through a New Zealand online doctor service that assesses you and has a local pharmacy dispense it. Overseas sites that ship without a prescription are not legal, and their tablets are often counterfeit.
How long does Viagra take to work, and how long does it last?
Take it about an hour before sex. It can work in as little as 30 minutes and keeps working for about four hours. It only works when you're aroused, and a heavy meal slows it down.
The bottom line
Viagra, or more precisely sildenafil, is easy to get legally in New Zealand and cheap once you have access to it. A pharmacist can supply it without a prescription if you're 35 to 70 and healthy, a GP can prescribe it at any adult age, and an online doctor can do the same without the waiting room. Whichever door you choose, don't skip the medical check: it's what makes the tablet safe for you, and it's the one thing an overseas website will never do. If you'd rather sort it from home, start your online assessment, a New Zealand-registered doctor will review it, and a Magna team member will call to confirm the right plan.
Sildenafil is a prescription medicine. Treatment is subject to assessment and approval by a New Zealand-registered doctor, and individual results vary. Viagra is a registered trade mark of its owner; Magna does not supply Viagra-branded tablets. Prices are indicative and vary between pharmacies. Ask your doctor or pharmacist whether treatment is right for you.
