Sildamax Review – A Generic Erectile Dysfunction Drug

photo of a pack of sildamax 100mg

Sildamax is one of a growing number of generic sildenafil – the active ingredient of the more well-known drug viagra.

It’s much less expensive than brand drugs like viagra, and is available without a prescription in many countries.

Despite being easier to get hold of, it has the same potential side effects and warnings as viagra. So it’s a good idea to make sure it’s suitable for you.

In this Sildamax review, I’ll be talking about my experience when I tested it with my partner. I’ll also discuss the potential side effects, risks and advice about using it safely.

Who makes it?

When I ordered it, I didn’t receive a box or information leaflet – just a blister packet of 10 tablets. So there was no information leaflet, but printed on the blister packet was this:

Exported by: Agron India Limited…Mumbai 40009 India

Agron India Ltd is a pharmaceutical company based in India. I’ve seen some websites that state it’s a reputable company.

I looked them up online, and although they have a website with many products listed, I couldn’t see Sildamax among them.

I’ve since written to Agron to find out more, as well as requesting some safety and usage instructions. I’ll update this review when I hear back from them.

What does it look like?

To help with identification, I’ve taken a photo with a Sildamax tablet next to a viagra pill.

The Sildamax is the large blue diamond, with 100 written on it. Viagra is smaller, lighter in color and has VGR 50 on it, though could also have VGR 25 or VGR 100.

sildamax and viagra comparison


The active ingredient is 100 mg sildenafil citrate. It’s the same ingredient as viagra, except viagra is available in three dosage levels – 25 mg, 50 mg and 100 mg.

The recommended starting dose of viagra is 50 mg, so I was surprised to find Sildamax came only in the higher 100 mg dose.

Since I didn’t receive a box or patient leaflet, I can’t confirm what other, presumably inactive, ingredients this batch contains. So I’ve asked Agron for more information about the ingredients too.

How does it work

Sildamax should work in the same way as other sildenafil-based erectile dysfunction drugs. Sildenafil increases blood flow to the penis, which helps you get and keep a hard enough erection for sex.

It usually takes 30 to 60 minutes to start working, and you only need to take it before you have sex.

It doesn’t automatically increase libido or give you an erection on its own though. You need to have some kind of sexual stimulation, to which you penis should respond better because of the increased blood flow.

My experience

When I tested viagra, I experienced a couple of side effects. So with the same ingredients, and at a stronger dose, I decided to keep a detailed timeline of what happened when I took the Sildamax.

  • 12.20 p.m. – took one pill with a large glass of water.
  • 12.45 – started feeling a little light-headed.
  • 12.55 – noticed my vision was a bit strange, especially with white and blue colors.
  • 1 p.m. – my partner tells me my face is red, and I also feel a bit flushed.
  • 1.10 – I decided I could tolerate the side effects. So we settled on the bed and got down to some foreplay. And literally within a minute of her touching me, I had a very hard erection – considerably harder than it normally gets.
  • 1.20 – noticed during sex that my nose felt stuffy, making kissing awkward as it was easier to breathe through my mouth.
  • 1.30 – finished having sex. My erection remained very hard for a few minutes, slowly reducing over the next 10 minutes.
  • 2.30 – still felt light-headed and with a stuffed nose, but it was tolerable. We decided to have sex again, and like before I was fully erect in under a minute of my partner touching me. My erection wasn’t as insanely rock hard as before, but was still very solid – probably equal to the best it ever gets without any pills.
  • 3.30 – the headache and stuffed nose seemed to have cleared up. My vision remained a little odd, but better than before.
  • 6 p.m. – felt completely normal again.

It works, but not without side effects

So the Sildamax clearly did what it was supposed to do; less than an hour after taking it, I was able to easily get, and keep a very solid erection.

And an hour later, I again found it easy to get a good erection. We didn’t try to have sex sooner than an hour after the first time. But I’m fairly sure it would have been easy to have sex sooner if we’d wanted to.

Despite the positive effects, I did have several side effects that took a few hours to completely clear up. They were tolerable for me personally.

But I imagine the strange vision, in particular, could be disturbing if you’ve never experienced anything like it before.

And with that, let’s take a closer look at the potential side effects and risks of Sildamax.

Possible side effects

Sildamax isn’t as well known as some others, with less information available about it generally.

So I think it’s useful to look at the known possible side effects of sildenafil citrate in the quantities typical of these type of drugs:

Rare and serious side effects

  • Priapism – an erection that won’t stop. If you have one for longer than 4 hours, it’s important to get medical help to avoid penis damage.
  • Vision loss – a potential sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy.
  • Hearing loss or ringing in the ears.
  • Heart problems.

If you have any of the above side effects, don’t take any more of the drug, and speak to a doctor straight away.

Common side effects

  • Headache
  • Dizziness
  • Indigestion, upset stomach, nausea
  • Flushing feeling, noticeable in the face and groin
  • back or muscle pain
  • Abnormal vision, such as color change (in particular seeing more blue), or blurred vision
  • Nasal congestion
  • Rash

I’ve personally experienced some of these side effects with viagra, Sildamax, and even erectile dysfunction herbal remedies.

For me, they were tolerable and cleared up in a few hours. But it’s a personal choice as to how much you’re willing to tolerate or not.

Risk of heart problems and death?

Drugs containing sildenafil citrate have had some controversy due to reported incidents of heart problems and even death.

The viagra website has this comment about that:

In addition, heart attack, stroke, irregular heartbeat and death have happened rarely in men taking VIAGRA. Most, but not all, of these men had heart problems before taking VIAGRA. It is not known if VIAGRA caused these problems.

Tell your healthcare provider if you have any side effect that bothers you or does not go away.

Some further advice comes on the useful website:

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of sildenafil.

And if you’d like to know more about the side effects associated with sildenafil, the website has an extensive list.

Who shouldn’t take sildamax?

Again, I think it’s worth considering the generic advice about sildenafil erectile dysfunction drugs.

And that means not taking it without medical advice if the following apply to you:

  • If you’re taking any medications called nitrates (prescribed for chest pain).
  • If you’re taking any pulmonary arterial hypertension medicines.
  • If you had a heart attack or stroke in the past, have heart disease or cardiac problems.
  • If you have liver or kidney disease.
  • If you have an eye disease called retinitis pigmentosa.
  • If you’re allergic to sildenafil.
  • If you don’t have erection problems.
  • If you’re a woman or child.

Some advice for taking Sildamax safely

Based on my own experience, and the research I’ve done into sildenafil, the best advice is to speak to your doctor before taking it, or any similar erectile dysfunction drug.

If you’re taking any medication, have a current or history of illness, my advice would be to clear it with your doctor – even if you can get it online.

I would also avoid accepting it from a friend, or anyone you don’t trust.

When you do take it, avoid alcohol or other recreational drugs. Drink it with plenty of water, which I and other reviewers have found helps alleviate some side effects.

Don’t take more than one pill in a 24 hour period. And if you have any serious side effects, or even less serious common ones that worry you, speak to a doctor immediately.



  • Can help you get a good erection easier, and keep it for the duration of sex.
  • Can help you get an erection again sooner after climax.
  • Improves your confidence and satisfaction with sex if you suffer from erectile dysfunction.
  • Works quickly – just 30 to 60 minutes before sex is enough.
  • Cheaper than brand drugs like viagra.


  • Like all sildenafil drugs, some side effects can be serious.
  • There are many common side effects to either tolerate or put you off taking it again.
  • It’s a generic erectile dysfunction drug, with less information than more famous brands.
  • Some men are at a higher risk and shouldn’t take it without medical approval.
  • Comes in a high dose of 100 mg.
  • It’s not a permanent cure for erectile dysfunction.


There’s no denying that Sildamax worked impressively well for me. I often have problems getting an erection unless I’m feeling particularly aroused. But with minimal stimulation, I was able to get a very good erection.

I also had no problems keeping a good erection for the duration of sex. And I was ready to go again in an hour, which doesn’t usually happen for me nowadays.

However, despite doing what it’s supposed to do, I did have a number of noticeable side effects.

I felt light-headed at first, my vision was a little strange, I had a stuffy nose that made me have to breathe through my mouth, and had a flushed, visibly red face. I was able to tolerate the side effects and enjoy the sex a lot. But it took several hours for them to completely go away.

My other concern is that Sildamax is a generic sildenafil drug. And that means it carries the same risk of side effects and warnings that more established brands like viagra do.

So my advice if you’re thinking of taking it is to check with your personal doctor if it will be safe for you.

Where to buy

At this time, I don’t personally feel comfortable in recommending any particular place to buy Sildamax. I know it’s widely available in India, and online in some other countries.

Have you tried Sildamax?

If you’ve tried it, or any other sildenafil drug, it would be great to hear your experience; I know other readers will appreciate it too. And if you have any questions, feel free to share them in comments below.

  1. Hi. After proposing to my (now) wife I for some reason developed extreme performance anxiety which of course caused quite some problems in our relationship. I at first went to the doctor who prescribed me another seldinafil medication which worked wonders. However my problem persisted so I started digging around for solutions and then discovered Cobra 120 (basically 120mg seldinafil) which I halved and it worked wonders. I have now purchased two Sildamax tablets which I will halve also and then try out. I prefer 100mg halved as I think side effects are less. Rather excited to try the Sildamax, it “looks” more like a legitimate product than the Cobra.

    1. Hi Eugene
      Thanks for sharing your experience. I wouldn’t base your decisions just on looks alone – some manufacturers just pay more attention to some details, but it doesn’t mean it’s any safer or better!
      All the best though – I hope you manage to get back on top of your anxiety.

  2. Yeah, I decided to have a go at the little blue pill. Yes, I can say it worked a treat but as mentioned above about the side effects, it was correct in that the white light / warm face etc did concern me a little but went away after a while. She was pleased anyway so that is a bonus. thanks for the info guys and great to read all the responses.

    1. Hi Jimmy
      Thanks for sharing your experience. Those side effects can be worrying, for sure. I guess it’s a personal choice if they are worth it or not.

  3. Have been buying Sildamax for years. Half a tablet is fine for me. Side effects are a stuffed up nose and lights look very bright with a blue or purple tint. Doesn’t work very well just after a big meal though.Thoroughly recommended and a fraction of the cost of Viagra.

    1. Hi Martin
      Thanks for sharing your experience. Those are similar side effects to me by the sounds of it. Interesting that you also found half a tablet works well enough.

  4. These are very good the best I’ve tried got a couple from a mate to try and hallelujah. I have recently been told i have type 2 and the prescribed viagra given to me 50 mg and 100mg have not worked at all. the only side effect i think I’m getting is an ache in my lower back. other than that pole vaulting again tonight as not been active for several months. i will ask my doctor to prescribe me sildamax from now on as i won’t have to cough up any cash.

  5. Hi Ethan. Just received 100mg version by post exactly as you described. Thought I should check on line before taking and found your review very helpful. A previous comment mentions quartering the pill. Would you have any comments about this? Thought about halving or quartering as not sure I could eat a whole one.

    1. Hi Angus
      I’m glad the review was useful! I think it’s probably ok to reduce the dosage if you’re concerned about the effects of the full 100mg. It’s pretty strong, so initially at least it might help mitigate the risk of side effects.

  6. Hi people, I’ve been using this for a while now and the results are very impressive, yes I have suffered from some of the side effects, but the pros outweigh the cons. I have even taken them around 10 in the evening and 8am I’m still solid lol, high recommend people.

    1. Hi Jason
      Thanks for sharing your experience of Sildamax. I guess that’s the decision many men will have to make with these strong drugs – if the benefits make some of the niggling side effects worthwhile dealing with. And that will always be a personal decision.

      1. I’ve tried taking the tablet as a half and there seemed to be no difference so took the second half an hour later and boom it was as solid as a rock still having an effect the next morning, but when I took the tablet as a whole a couple of days later there was little effect at all, no side effects whatsoever.
        Reading previous posts I was waiting a couple of hours for it to work, would you suggest a maximum of an hour prior to sex?

        1. Hi PJ
          That’s an interesting experience by the sounds of it. I think an hour is generally enough time – I personally wouldn’t leave it too much longer without a reason to.

  7. Hi Ethan,
    last night i tried Sildamax (got it from EBay) after ‘consulting’ your review and was a bit afraid of possible side effects but everything turned out just fine. Me and wife had around 20 minutes of quality sex with changing positions. Was all wet afterwards like chopping the wood. I appreciate that since i normally achieving a plateau around 5 min of sex and this was a real deal for me. Usually i have no problems with getting erections, but sure thing Sildamax give me sword strong erection. I appreciate your review and in my opinion definitely will use this medicine lot of times again. I think it’s a miraculous pill and make me feel like a super (powered) hero :-) which is great for sexual confidence too.
    Regards, Tom

    1. Hi Tom
      Thanks for sharing your experience. I don’t know if it’s a typo, but you say “usually I have no problems with getting erections”. If that’s the case, then the normal medical advice is not to take ED medication. At the end of the day, it might give you an even stronger erection, but you have to balance the effect it has on your body with the result. And if you don’t really need it in the first place, my opinion would be it’s best to avoid these kind of strong medications.

  8. Hi,

    I have used this product for a couple months now and I do notice some slight side effects, flushed face, stuffy nose and even the blueish vision but they don’t last long and the pros outweigh the cons for me. One question though has anyone taken it overseas with them? Going to Canaries for week holiday and was wanting to take a strip of 6 tablets packed away in washbag in suitcase. Would this be ok?

    Thanks for any feedback.

    1. Hi there
      Thanks for sharing your experience. I did travel with it from the UK to South America and had no problem. But I have no idea if it’s ok for your trip.

      1. Thanks for the feedback. I was fine taking it to Spain/Canary islands. I think as long as you put it in your case in original blister packaging and don’t take anymore than necessary for your trip then no one is going to notice or bother with them. It may be slightly different in hand luggage going through security. Anyway it helped me relax and make the most of my holiday!

        1. No Problem John. My thoughts exactly. I’ve taken various different PE and ED treatments in and out of both England and the United States and never had a problem either.

  9. Used Sildamax for the first time today. Slightly nervous having read of your experience. I wasn’t feeling any side effects and actually wandered if it would work. Sure enough, the slightest sexual contact resulted in instant arousal that sustained for about an hour, gradually diminishing over the course of 10 minutes after ejaculation. Still had a couple of random erections 4-5 hours later. I drank a full glass of water when taking, and another 30 mins later. Only sensation was a vaguely pleasant one in the loins. I think I read somewhere that the side effects may only affect 10% of people, not sure on that stat, though.

    1. Hi Steven
      Sorry for making you worry with the review! I have to be upfront when writing about my experiences though. Having said that, you’re right in that not everyone will have side effects – I don’t know the stat either.
      Anyway, it’s great that it worked so well for you – and useful for other readers to hear about.

  10. Recently met a girl and really fallen for each other. Had a 5 year break from sex after splitting with a long time partner. I was really stressed when it got to having sex with my new girl and 2 nights in a row i could not perform…gutted (im 34 btw).

    A friend suggested the product you tested and the following weekend we managed 3 2 hour sessions. It felt like a miracle. No side effects to speak of for me. Confidence boosted, now down to quarter tablet a pop.

    1. Hi Bri
      Thanks for sharing your experience. It’s great that you had such good results from it, and no side effects. I don’t doubt there are men who will have a very different experience from me, so it’s good to hear a different side.

  11. Why Use generic?
    I recommend you to levitra 5 mg and you have no side effects!!
    levitra with stud100 or other it is a best.
    You hold an hour…

    1. Hi Amit
      I agree that it’s better to use a brand medication if possible. But I test all kinds of products to let readers know how they work, and also in the hope that I’ll find some gems in the rough!

    1. Hi J D
      There’s not much I can do to help other than recommend reading different articles on this site, and others, to find out what your options are and advice about different techniques and products for erectile dysfunction.

  12. Varies according to age and how long you’ve been taking it. Been using Sildenfil for about 8 years, and with my advancing age (71) no side effects at all. I’m taking 150 mg.
    I am a heart patient for 15 years, but the product isn’t working as well as it used to! (my age)? I found that all the suppliers online are from India, even ordering from the Canadian Pharmacies on anywhere. Beware, they will hound you daily (on the phone) when your name is sold to many other suppliers!

    1. Hi Joe
      Thanks for sharing your experience. Out of interest, being a heart patient, did you clear taking sildenafil with your doctor beforehand? Have you had any side effects at all from using it?
