Introduction
Sildenafil citrate, originally marketed as Viagra, remains one of the most commonly used prescription treatments for erectile dysfunction (ED). Multiple Indian pharmaceutical companies market sildenafil under different brand names, usually in the standard 25 mg, 50 mg, and 100 mg strengths.
The wide selection can make comparison difficult. Prices, pack sizes, pharmacy availability, and the company named on the package vary considerably. Product identity also deserves attention because similarly named medicines may be marketed by different companies in domestic and export channels.
This guide was reviewed in August 2026. It compares leading sildenafil brands using practical market factors rather than claiming that one brand produces stronger erections, works better, or is inherently safer. Sildenafil citrate is a well-established prescription medicine in India, but the appropriate product and dose depend on a legitimate supply chain, correct prescribing, interacting medicines, cardiovascular status, response, and tolerability.
How We Compared the “Best” Sildenafil Brands
“Best” in this guide refers to practical comparison factors, not proven clinical superiority. The brands are compared by the company currently identified as manufacturer or marketer, standard strengths, pack size, visibility at established Indian pharmacies, August 2026 MRP, and how easily the product can be traced through a legitimate pharmacy supply chain.
Most of the products below are labeled as sildenafil citrate tablets. That does not justify a blanket claim that every individual brand has publicly documented bioequivalence to Viagra or that every product using the same brand name comes from the same source. The Central Drugs Standard Control Organization oversees national drug regulation, while licensing, manufacturing, and enforcement responsibilities are also shared with state authorities.
Standard erectile-dysfunction dosing is another important boundary. Established prescribing frameworks use 25 mg, 50 mg, and 100 mg tablets, with 50 mg commonly used as the starting dose. Products above 100 mg may appear in some export catalogs, but higher strength does not automatically mean better treatment and is not included here as a practical advantage.

Brand Mini-Profiles
The profiles below describe current market identity, standard strengths, pack format, and August 2026 MRP position.
Suhagra — Cipla
Suhagra is marketed by Cipla and is currently listed in 25 mg, 50 mg, and 100 mg strengths. Suhagra 100 mg is commonly sold in strips of four tablets and appears across major Indian pharmacy platforms.
The August 2026 MRP for four 100 mg tablets was ₹239.58, equivalent to approximately ₹59.90 per tablet before pharmacy discounts.
Silagra — Cipla
Silagra is another Cipla sildenafil brand with current 25 mg, 50 mg, and 100 mg listings. Its packaging, product name, pack availability, and price differ from Suhagra even though both are marketed by Cipla.
Silagra 100 mg had an August 2026 MRP of ₹180.90 for four tablets, or approximately ₹45.23 per tablet.
Penegra — Zydus Cadila
Penegra is marketed by Zydus Cadila and has current Indian listings in the standard 25 mg, 50 mg, and 100 mg strengths. Packs of four tablets are common for the 100 mg product.
The verified August 2026 MRP for Penegra 100 mg was ₹486.65 for four tablets. Discounted pharmacy prices may be lower, but the MRP is used here to keep the comparison consistent.
Caverta — Sun Pharmaceutical Industries
Caverta is currently listed under Sun Pharmaceutical Industries and is available in 25 mg, 50 mg, and 100 mg strengths. The 100 mg product is commonly supplied in a four-tablet strip.
Caverta 100 mg had an August 2026 MRP of ₹443.44 for four tablets, or approximately ₹110.86 per tablet.
Zenegra — Alkem Laboratories
Zenegra is marketed by Alkem Laboratories. Current major-pharmacy listings support 50 mg and 100 mg tablets; older catalogs may show additional presentations that are not routinely stocked.
The August 2026 MRP for Zenegra 100 mg was ₹215.60 for four tablets, approximately ₹53.90 per tablet.
Vigore — Zydus Healthcare
Vigore is the exact spelling used in the current domestic listing reviewed for this update. It is marketed by Zydus Healthcare and appears in 50 mg and 100 mg strengths. It should not be automatically merged with similarly named “Vigora” products found in other markets or catalogs.
Vigore 100 Red had an August 2026 MRP of ₹131.48 for four tablets, placing it among the lower-priced four-tablet packs in this comparison.
Manforce – Mankind Pharma
Manforce sildenafil is marketed by Mankind Pharma and remains visible in current Indian pharmacy listings in 50 mg and 100 mg strengths. Four-tablet strips are commonly listed for the 100 mg product.
Manforce 100 mg had an August 2026 MRP of ₹265 for four tablets, equivalent to approximately ₹66.25 per tablet.
Kamagra — Ajanta Pharma
Kamagra tablets are associated with Ajanta Pharma, but the different dosage forms sold under the broader Kamagra name must be distinguished. Current listings include sildenafil tablets, while Kamagra Oral Jelly is a separate formulation and should not be priced as though it were the same tablet product.
Kamagra 100 mg tablets had an August 2026 MRP of ₹123.09 for four tablets, although the reviewed domestic listing was unavailable at that time. Stock can be inconsistent, and unusual export-market strengths are not included in the main Indian comparison.
Cenforce – Centurion Laboratories and Other Market Listings
Cenforce requires more careful identification than most brands in this guide. Centurion Laboratories documents Cenforce sildenafil products, including standard 25 mg, 50 mg, and 100 mg tablets, in its manufacturer catalog. The company also shows higher export-market strengths, but those exceed the standard ED dosing range and are not included as an advantage.
A current Indian retail product called “Cenforce 100 mg” was listed under a different marketer, Xovak Pharmtech. That domestic MRP was not used to represent Centurion’s product because the company identity did not match. Anyone comparing Cenforce listings should verify the marketer or manufacturer shown on the actual pack.
Sildenafil Brand Prices in India — August 2026
Prices vary substantially by brand, strength, and pack size. To make the comparison consistent, this guide uses the August 2026 MRP for four-tablet packs of 100 mg sildenafil wherever a matched domestic product was available.
Among the matched Indian-brand packs, MRPs ranged from ₹123.09 to ₹486.65 for four 100 mg tablets. Pharmacy discounts can reduce the checkout price, so the amount actually paid may be lower. Branded Viagra remained substantially more expensive at an MRP of ₹1,125 for four 100 mg tablets.
Price does not indicate clinical performance or manufacturing quality.
Availability and Authenticity Checklist
Counterfeit and poorly traceable erectile-dysfunction medicines remain a concern, particularly on websites that conceal the dispensing pharmacy or marketer. Visual packaging features are not sufficient proof: artwork can change, genuine products do not all use the same security features, and counterfeit packaging can imitate a hologram.
When sildenafil is dispensed, check for an intact carton or blister, matching product name and strength, manufacturer or marketer details, batch number, manufacturing and expiry dates, MRP, applicable Schedule H or prescription labeling, and a pharmacy invoice or receipt. The details on the carton and blister should agree. Damaged, altered, loose, or relabeled tablets should not be accepted.
Purchase through a licensed pharmacy with a traceable address and dispensing process. A seller willing to bypass India’s prescription requirement is a regulatory red flag. It does not by itself prove that the tablets are counterfeit, but it removes an important safeguard and makes the seller and supply chain harder to trust. See the site’s sildenafil prescription and online-pharmacy guidance for a fuller explanation.
Safety First
Sildenafil is generally well tolerated when appropriately prescribed, but contraindications, interacting medicines, cardiovascular status, and dose still matter. Common adverse effects include headache, flushing, indigestion, nasal congestion, dizziness, and temporary visual disturbances.
According to current sildenafil prescribing information, the usual recommended ED dose is 50 mg taken as needed, generally about one hour before sexual activity. It may be taken approximately 30 minutes to four hours beforehand. The dose may be reduced to 25 mg or increased to 100 mg according to response and tolerability, but the maximum recommended dose is 100 mg and the maximum frequency is once in 24 hours. Sexual stimulation is still required for an erection. More detail on dose adjustment and upper limits is available in the site’s guide to the maximum sildenafil dose.
Sildenafil must not be combined with nitrates such as nitroglycerin or isosorbide because blood pressure can fall dangerously. It is also contraindicated with riociguat. People using alpha-blockers, blood-pressure medicines, or strong CYP3A4 inhibitors may require additional assessment or a lower dose.
An erection lasting more than four hours requires urgent medical attention. Sudden loss or marked deterioration of vision or hearing also warrants prompt care. Chest pain during sexual activity should be treated as an emergency, and nitrate medicine should not be taken after sildenafil unless an emergency clinician specifically directs otherwise.
Food, Alcohol, and Drug Interactions
Sildenafil can be taken with or without food, but a high-fat meal can delay absorption and postpone its effect. Taking it after a lighter meal may make the timing more predictable; this does not justify taking an additional tablet if the effect seems delayed.
Alcohol is not an automatic contraindication, but substantial drinking can worsen erectile function and increase dizziness, flushing, headache, or low blood pressure. The combined effect is particularly relevant for people already taking antihypertensive medicines.
Nitrates and riociguat are the critical prohibited combinations. Alpha-blockers can add to the blood-pressure-lowering effect, while medicines that inhibit CYP3A4—including certain antifungals, macrolide antibiotics, and HIV treatments—can raise sildenafil exposure. A prescriber or pharmacist should review all prescription medicines, nonprescription products, and supplements before treatment begins.
How Other PDE5 Inhibitors Differ
Sildenafil is one of several prescription phosphodiesterase type 5 inhibitors used for erectile dysfunction. Tadalafil, vardenafil, and avanafil act through the same general pathway but differ in duration, timing, strengths, interactions, and current Indian availability. None is universally better.
| Medicine | Approximate onset | Approximate duration | Common strengths | Practical distinction |
|---|---|---|---|---|
| Tadalafil | 30–60 minutes | Up to 36 hours | 2.5 mg, 5 mg, 10 mg, 20 mg | Longer treatment window; daily and as-needed regimens exist |
| Vardenafil | 30–60 minutes | About 4–6 hours | 5 mg, 10 mg, 20 mg | Duration broadly similar to sildenafil |
| Avanafil | Approximately 15–30 minutes | About 6 hours | 50 mg, 100 mg, 200 mg | Can have a faster onset; retail availability may be more limited |
These medicines are prescription treatments and share important cautions, including the nitrate contraindication. Their milligram strengths are not directly interchangeable. The broader guide to erectile-dysfunction treatments explains medication and non-medication options in more detail.
Frequently Asked Questions
Which sildenafil brand is best in India?
No single brand is best for everyone. Practical considerations include the exact manufacturer or marketer, prescribed strength, pharmacy availability, pack size, traceability, and MRP.
Which sildenafil brands are currently available in India?
Current listings include Suhagra, Silagra, Penegra, Caverta, Zenegra, Vigore, Manforce, Kamagra, and branded Viagra. Cenforce also appears in manufacturer and retail channels, but the company associated with the name can differ, so exact product identity must be checked.
Is generic sildenafil as effective as Viagra?
Legitimate generic sildenafil is intended to deliver the same active ingredient and pharmacologic effect as branded sildenafil. This guide does not independently certify every product or claim that publicly accessible brand-specific bioequivalence documentation exists for every listing.
What is the difference between Viagra and Indian sildenafil brands?
Viagra is the original brand name; Indian sildenafil products use the same active ingredient under different brand names. They may differ in manufacturer or marketer, excipients, tablet appearance, packaging, pack size, and price.
How much does sildenafil cost in India?
In the August 2026 MRP comparison, four-tablet packs of 100 mg Indian brands ranged from ₹123.09 to ₹486.65. Viagra 100 mg had an MRP of ₹1,125 for four tablets. Pharmacy discounts may reduce the amount actually paid.
Is sildenafil available over the counter in India?
No. Sildenafil is a prescription medicine in India. A seller offering it without the required prescription is bypassing an important regulatory safeguard.
How can you identify legitimate sildenafil?
Use a licensed pharmacy and check the intact pack, exact brand and strength, named manufacturer or marketer, batch number, manufacturing and expiry dates, MRP, prescription labeling, and invoice.
Does a hologram prove that sildenafil is authentic?
No. A hologram may be one packaging feature, but it cannot prove authenticity by itself. Packaging can change, and counterfeiters can imitate visual security features.
What if a seller offers sildenafil without a prescription?
That is a regulatory red flag, but it does not automatically prove that the tablets are counterfeit. It does mean that an important dispensing safeguard has been removed and that the seller’s supply chain may be harder to verify.
Is 200 mg sildenafil stronger or better?
A 200 mg tablet contains more sildenafil, but it is above the standard maximum recommended ED dose of 100 mg in 24 hours. More drug does not guarantee a better erection and can increase adverse effects. Patients should not combine tablets or increase the dose independently.
Can sildenafil be purchased online in India?
Licensed online pharmacies may dispense sildenafil after receiving a valid prescription. The dispensing pharmacy, business address, invoice, and product source should be traceable.
Is tadalafil better than sildenafil?
Not universally. Sildenafil generally has a shorter treatment window, while tadalafil can remain effective for up to 36 hours. Medical history, other medicines, preferred timing, adverse effects, and response determine which option is more appropriate.
