Generic Viagra

Viagra (generic name: Sildenafil) is a pill used for the anti-ED therapy in males. It works by improving the blood circulation in the penile area. There are two versions of this tablet available on the market. One is used for ED therapy, the other one is used for PHTN treatment – Revatio.


There are many things to take into consideration before you commit to any kind of treatment, especially this one. You must not take this drug if you’re at higher risk of an allergic reaction to Sildenafil.

You must not take this drug if you:

  1. Have previous history of cardiovascular issues, including arrhythmia, angina and congestive heart failure.
  2. Have previous/underlying/current issues with your kidneys and/or liver.
  3. Have ever suffered from hypertension or hypotension.
  4. Have issues with your penis, including Peyronie’s diseases, phimosis, and angulation.
  5. Have ever had issues with prolonged/painful erections.
  6. Have blood diseases, including sickle cell disease and plasma cell myeloma.
  7. Have issues with your eyes.
  8. Have bleeding disorders.
  9. Have active gastric ulcers.

The above list of precautions is not complete. You should undergo a complete physical evaluation conducted by your MD before you start the Viagra treatment.


Let’s split the information regarding the dosage into two different categories, based on what kind of condition is being treated.
ED treatment.

Usual starting dosage is 50 milligrams. However, your MD must figure out what dosage works best for you, based on your previous experiences and overall well-being level. Your dosage might be altered based on your body’s response to the treatment. It can either be upped to 100 milligrams or lowered to 25 milligrams. Never try to change the dosage on your own.

This medication is taken approximately 60 minutes before the scheduled sexual activity. Food timing is not important. Never take this pill more than 1 time in the span of twenty-four hrs. You must also be mindful of the fact that this drug works differently for different people. In other words, people take it anywhere from 20 minutes to 300 minutes before sexual contact. You might not get it quite right on your first try.

Pulmonary hypertension treatment.

  • Revatio is usually taken three times in the span of 24 hours, starting dosage usually is 20 milligrams.


Despite this drug’s fame as one of the safest ways of curing erectile dysfunction, there are still some minor adverse responses you need to be mindful of. You can still experience some unwanted responses if you swallow the incorrect dosage. Viagra remains one of the most thoroughly researched pills in the history of pharmaceutics, so here are the most prevalent unwanted responses encountered by the people undergoing this treatment:

  • Vertigo;
  • Nasal congestion;
  • Dyspepsia;
  • Impaired vision;
  • Flushing;
  • Hypersensitivity to light.

There are some severe adverse reactions that are uncommon (happen in<0.01 of patients):

  • Blurry vision;
  • Temporary blindness;
  • Painful/prolonged erection of penis;
  • Acute myocardial infarction;
  • Impaired hearing;
  • Heightened opthalmotonous pressure.

Disclaimer: the above list of possible unwanted responses is not exhaustive. Always get in touch with your specialist if you encounter any of the aforementioned symptoms or anything out of the ordinary. Never stop taking this pill or alter the dosage without consulting with your MD first.


There’s a chance of overdose while on Viagra. Although it is worth pointing out that overdose is highly unlikely, you still need to tread carefully when it comes to taking a pill with such a strong potency. If your dosage is off, it could possibly cause an overdose. The max allowed dosage is 800 milligrams. In case you take more than you should have, you are going to experience more severe versions of the aforementioned symptoms and lightheadedness, dizziness and fainting. Here are some other symptoms of an overdose:

  • Vomiting;
  • Sudden blindness;
  • Arrhythmia;
  • Muscle breakdown;
  • Papillary stasis.

If you feel like there’s a chance of an overdose, you need to immediately contact your nearest healthcare center. You will require urgent medical attention.


Your treatment’s desired effect may change based on its interactions with the pill you are currently taking. These interactions may alter the effect, delay it or increase your chances of suffering unwanted adverse responses. Here’s an incomplete list of interactions for Viagra:

  • Various anti-ED pills, namely Cialis and Levitra.
  • Nitrates, i.e. medications used for angina treatment.
  • Alkyl nitrites (“poppers”), i.e. drugs containing amyl, butyl or isobutyl nitrite.
  • Alpha-blockers, namely prazosin, indoramin, doxazosin, terazosin, alfuzosin, tamsulosin.
  • Antifungal agents, namely ketoconazole, voriconazole, itraconazole, telithromycin, clarithromycin, saquinavir, nefazodone, erythromycin, diltiazem, fluconazole, verapamil, cimetidine, ranitidine, roxithromycin, fluvoxamine, among many others.
  • Antibacterials, namely ketolide, azithromycin, erythromycin, clarithromycin, telithromycin, roxithromycin, and cethromycin.
  • Protease inhibitors used to treat AIDS, namely amprenavir, atazanavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, efavirenz, and nevirapine.
  • Hepatitis C medicines, namely ribavirin, and telaprevir.
  • In order to steer clear of the possible interactions, you must write down the comprehensive list of all the pills you are currently using (OTC meds, herbs, and prescribed pills) and hand it to your MD.

Food Interactions

Based on the drug’s interactions with food, you might have to change your diet. Here are some of the foods that interact with this particular pill.

1. Grapefruit/grapefruit juice. Even a single glass of the juice can boost your chances of encountering unwanted adverse respones, especially hypotension and flushing. Even if you are lucky enough not to suffer from the above-mentioned secondary responses, grapefruit will likely delay this drug’s effect. In other words, you might not get a strong erection. There’s also a possibility of encountering unwanted response after approximately a full day of taking the pill. There are many similar fruits, so you might consider a simple substitute.

2. Fat-heavy foods. These interactions are not as severe, but you are strongly suggested to avoid any and all foods with high fat contents. The fatty foods (including cheese and nuts) can slow down the intended effect. You also are at a higher risk of encountering some of the side-effects, but it’s nothing major. Always pay attention to your body’s response to the treatment AND your change of diet.

Alcohol Interactions

This is one of the most common questions on the internet. Some people say (and it’s entirely anecdotal evidence) that liquor helps them perform even if they take Viagra. They drink in moderation, they do not encounter any adverse effects. While this may be true for some patients, your experience is going to be completely different. Many studies suggest that it is perfectly normal to drink a glass or two before engaging in sexual activity, but you’re always strongly advised to avoid liquor if you can.

The possible interaction of the two causes a significant BP drop which, in turn, leads to wooziness, lightheadedness and some even more severe issues, including fainting and arrhythmia. The bottom line is if you can avoid alcohol for a day – do it.
How to Boost This Drug’s Effectiveness

Viagra is renowned for being one of the most effective anti-ED medications in history. Nevertheless, there are still some lifestyle changes that you can make in order to eradicate your ED completely. Some of those changes include:

  1. Quitting smoking. Smoking is bad for your health overall, it’s no big secret. However, not many people know that this habit can also lead to impotence.
  2. Losing weight. Being overweight is not healthy by any stretch. Overweight people frequently suffer from libido loss and ED.
  3. Leading a more active lifestyle. This one is self-explanatory. Staying active means staying healthy. Sedentary lifestyle is not doing any good for anyone.
  4. Curbing your alcohol intake. Not only does liquor cause interactions with this drug, it is also one of the leading causes of ED. Excessive drinking is responsible for many, many ED cases. Studies show that as much as 77% of men that suffer from alcoholism are also suffering from ED.
  5. Finding a good exercise regimen and finding a healthy diet. This is closely related to #2 and #3.
  6. Living a more stress-free life. There’s plethora of evidence pointing to stress and anxiety as leading causes of ED. They frequently get overlooked in favor of obesity and other physical causes.

These are just some of the changes you might make to both increase the effectiveness and help this drug eradicate your erectile dysfunction. Even making a few small steps in the right direction will yield significant results. It is hard, but you can take it slow.

Well, my story is pretty straightforward. I started having issues with my erections, started losing confidence, etc. Then I asked my doctor about the problem and he prescribed Viagra. Honestly, it works great. I take it a full hour before (50 milligrams works fine for me, for now) the intercourse and everything works out just marvelously. Sometimes I experience some minor side-effects, but it is completely worth it. I guess it’s on me, mostly. Drank more than I should have this one evening…

I’m 65 years old. Recently, I started having some serious issues with my erections. My doctor suggested Viagra, right? I was kind of apprehensive at first, because this whole ordeal was shameful. I mean, I was starting to feel like a total failure. Anyway, Viagra worked for me – my wife loves it and she is actually able to reach climax every single time we get it on. Sometimes twice! All in all, it is a wonderful product. Now I live a happy life because I have I happy wife! Don’t miss out on this.

At first, I was experiencing MANY side-effects. Like, actually a lot – flushing, headaches, blurry vision, the whole nine yards. Luckily for me, it was because the dosage was incorrect not because I just couldn’t stomach Viagra. So my DR figured out a better treatment regimen and now everything works like a charm. I always can count on my erections, no matter what. There are still some minor side-effects (really minor this time around), other than that – it is perfect. Now I’m actually living my life to the fullest.

Once I hit my late 60s, my erections had become unreliable to say the least. With performance issues came performance anxiety. Talking to my doctor made me realize that it’s okay, that I’m not alone in this. I was prescribed Viagra. Used the 50 mg. dosage, everything works just fine – can last up to 20 minutes as well. There were some instances when I suffered minor side-effects, including flushing and blurry vision. Nothing major. My wife is happy, and I’m happy that my sex life is back on the right track.
