ED medicine prices in the Philippines
Viagra price in the Philippines, and cheaper generics
Branded sildenafil (Viagra) prices at Watsons by strength, compared with every verified generic: Erecto, Spiagra, Zilden, RiteMed and more.
Short answer
Branded sildenafil (Viagra) at Watsons costs ₱915 a tablet at 50 mg and ₱1,168 at 100 mg, the highest verified sildenafil prices in the Philippines. Generic sildenafil at the same strength starts at ₱49 for 50 mg. Both are the same medicine, and both need a prescription.
Viagra is the brand most people search for, but it is no longer the only way to get sildenafil, and in the Philippines it is by far the most expensive. This page shows what the original costs, compares it strength by strength with every verified generic, and explains what you do and do not give up by choosing a generic.
How much is Viagra in the Philippines?
At Watsons, branded sildenafil (Viagra) is listed at ₱683 for 25 mg, ₱915 for 50 mg and ₱1,168 for 100 mg, each per tablet. Those are the highest verified sildenafil prices at every strength.
Viagra was developed by Pfizer and was the first PDE5 inhibitor approved for erectile dysfunction, in 1998. In the Philippines it is sold per tablet, behind the pharmacy counter, with a prescription. Its active ingredient is sildenafil citrate, and since the patents expired, many companies make the same ingredient under their own brand names.

How much is Viagra at Watsons?
Watsons is the only chain where we have verified Viagra prices so far, at all three strengths. The figures in the table above are Watsons' own listed prices on the date shown.
Watsons also carries more sildenafil generics than any other chain we checked: Andros, RiteMed, Zilden, Tigerfil and Robust Plus. So if you are at a Watsons counter with a prescription for sildenafil, you can usually ask the pharmacist to show you the generic options next to the original.
How much is Viagra at Mercury Drug?
We do not have a verified Mercury Drug price for Viagra yet. We publish a price only when we can link to the listing it came from, and we have not been able to do that for Mercury Drug.
Mercury Drug is the largest pharmacy chain in the Philippines, so it is a fair question, and we are working on it. Until then, ask at your branch. If you see a figure for "Viagra at Mercury Drug" on another site with no date or source, treat it with caution. When we verify one, it will appear in the table above with its checked date.
How much cheaper is generic Viagra?
Much cheaper. At 50 mg, branded sildenafil (Viagra) costs about 19 times as much as the cheapest verified generic; at 100 mg, about 23 times.
The tables below put the original next to every verified generic at each strength, sorted from cheapest to dearest.

What a month looks like
If your doctor prescribed sildenafil 50 mg and you used it 4 times a month, branded sildenafil (Viagra) would come to ₱NaN, against ₱NaN for Zilden and ₱NaN for Erecto. These are illustrations only; how often you use it is your doctor's decision.
Is generic Viagra as good as the real thing?
A registered generic is the same medicine. It must contain the same active ingredient at the same strength and be bioequivalent, meaning it reaches the bloodstream in the same amount and at the same rate as the original.
The US FDA describes approved generics as working "in the same way" as their brand-name versions. Philippine policy pushes in the same direction: the Generics Act of 1988 makes doctors write the generic name on prescriptions, and the Cheaper Medicines Act of 2008 (RA 9502) was passed to widen access to lower-priced quality medicines.
What you pay extra for with the original is the name, the long track record of that specific product, and the tablet's familiar look. What differs in a generic is the maker, the tablet's colour and shape, the inactive ingredients and the box. For details of each generic, see the brand pages for Viagra, Erecto, Spiagra, Zilden and RiteMed sildenafil.
The real risk is not registered generics, it is unregistered pills. Fake "Viagra" and "herbal" capsules spiked with sildenafil are sold online and on social media, and the FDA Philippines has issued repeated warnings about them. Check any brand on the FDA Philippines verification portal (verification.fda.gov.ph), and read how to spot fake ED pills.
Which pharmacies stock Viagra and its generics?
Watsons stocks the original and most generics. TGP lists Erecto and Spiagra, Southstar Drug lists Zilden and Kohagra, and Rose Pharmacy lists RiteMed sildenafil.
- Watsons: sildenafil (Viagra), Andros, RiteMed, Zilden, Tigerfil, Robust Plus.
- TGP: Erecto, Spiagra.
- Southstar Drug: Zilden, Kohagra.
- Rose Pharmacy: RiteMed sildenafil.
- MedsGo: lists several sildenafil brands; prices still being verified.
- Mercury Drug: no verified price yet.
Stock differs by branch, so a quick call before you go helps, especially outside Metro Manila. All of these pharmacies ask for a prescription.
What should you ask the pharmacist about Viagra and its generics?
Ask which sildenafil brands they have in stock at your prescribed strength, and what each costs per tablet today. Pharmacists in the Philippines are used to this question, and it is the quickest way to see the real shelf price.
A few other questions are worth a minute at the counter:
- Is this registered? Every product a chain pharmacy dispenses should carry an FDA Philippines registration number on the box. You can check it yourself on the verification portal.
- Is it sold per tablet or per box? Most ED tablets are sold per piece, but some, such as Robust Plus, come in boxes. Compare the per-tablet price, not the box price.
- Are you a senior citizen? Filipino citizens aged 60 and over, living in the Philippines, are entitled under RA 9994 to a 20% reduction and VAT exemption on medicines for their own use, with an OSCA ID and a prescription. Expats do not qualify under this law.
If you pay in dollars, pounds or euros, the prices in your currency page shows the same tables converted at a fixed reference rate.
Can you get Viagra without seeing a doctor?
No. Sildenafil (Viagra) is a prescription medicine in the Philippines, and pharmacies must see a valid prescription. See is Viagra over the counter? for the rules and the legal routes to a prescription.
The consultation is not just paperwork. ED is often an early sign of diabetes, high blood pressure or heart disease, and a doctor checks for medicines that make sildenafil unsafe, such as nitrates for chest pain. The doctor also decides the strength. For side effects, see ED medicine side effects and safety.
Are these Viagra prices current?
They are as current as the checked date on each row. Pharmacies change prices, and the price at the counter can differ from the online listing.
For every sildenafil brand in one place, see the sildenafil price guide. If you are weighing a longer-acting option, the Cialis price guide does the same comparison for tadalafil. All verified prices are on the prices hub, and our method is set out in how we check prices.
