Do not take VIAGRA (sildenafil citrate) tablets if you:

  • take any other medicines called nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure.
  • are allergic to sildenafil, as contained in VIAGRA and REVATIO, or any of the ingredients in VIAGRA.

Discuss your health with your doctor to ensure that you are healthy enough for sex. If you experience chest pain, dizziness, or nausea during sex, seek immediate medical help.

VIAGRA can cause serious side effects. Rarely reported side effects include:

  • an erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help right away. If it is not treated right away, priapism can permanently damage your penis.
  • sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). Stop taking VIAGRA and call your healthcare provider right away if you have any sudden vision loss.
  • sudden hearing decrease or hearing loss. Some people may also have ringing in their ears (tinnitus) or dizziness. If you have these symptoms, stop taking VIAGRA and contact a doctor right away.

Before you take VIAGRA, tell your healthcare provider if you:

  • have or have had heart problems such as a heart attack, irregular heartbeat, angina, chest pain, narrowing of the aortic valve, or heart failure
  • have had heart surgery within the last 6 months
  • have had a stroke
  • have low blood pressure, or high blood pressure that is not controlled
  • have a deformed penis shape
  • have had an erection that lasted for more than 4 hours
  • have problems with your blood cells such as sickle cell anemia, multiple myeloma, or leukemia
  • have retinitis pigmentosa, a rare genetic (runs in families) eye disease
  • have ever had severe vision loss, including an eye problem called NAION
  • have bleeding problems
  • have or have had stomach ulcers
  • have liver problems
  • have kidney problems or are having kidney dialysis
  • have any other medical conditions

Treatment with VIAGRA

Erectile dysfunction (ED) treatment can be effective. Together, you and your doctor can decide if VIAGRA (sildenafil citrate) or another treatment is right for you.

VIAGRA works only when you are sexually stimulated. Take it about 1 hour before sexual activity. You may take VIAGRA between 30 minutes to 4 hours before sexual activity if needed. So don't worry. There's plenty of time to be spontaneous with your partner.

After sex? Your erection should go away. In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.

By now, you may have decided to have your VIAGRA (sildenafil citrate) Talk. This can be with your regular doctor. Or you can talk to a specialist like a urologist. VIAGRA isn't right for everyone, but either doctor can prescribe VIAGRA if they decide it's right for you. And you will need a prescription.

Even though men act reckless in most cases during their daily lives, there is at least one situation when absolutely all of us turn super-serious and precautious. As you might have already guessed, this is when our penises are at risk. Thus, it's only natural that most of us want to be 100% sure about ED meds before taking them. Tonight we will start by assessing the risks of taking the most famous erectile dysfunction medication of all times – Viagra.

Is Viagra safe? Unfortunately, at this very moment it's impossible to answer this question positively and with full confidence. There are a number of adverse effects that this ED medication causes and there's virtually no way you can take it 100% risk-free. On the other hand, it's known that the vast majority of reported adverse effects were observed in people who took more Viagra than they were advised to or took it more frequently than recommended. Other patients were suffering from health conditions that made side effects of Sildenafil more likely to occur. Thus, you can increase your chances of enjoying sex with Viagra without any unpleasant side effects by following these two simple guidelines:

1) Consult with your healthcare provider prior to starting treatment with Viagra. Get all necessary tests done in order to see if Viagra is the best option for you or if you should consider some other medicine.

2) Always take Viagra according to doctor's prescription. Under no circumstances should you take more than 100mg of Sildenafil in under 24 hours.

That's very simple to follow the two principles above and they reduce your risks to negligible levels.

But what are the side effects that people taking Viagra fear so much? In fact, there are many of them but only a few are regarded as really dangerous for your health and life. They have occurred in an extremely small number of cases and included heart attack or arrhythmia, stroke, sudden hearing loss and priapism. Thus, if you feel irregular heartbeat, chest pain or have an erection that lasts for more than 4 hours after taking Viagra, call the doctor for help immediately.

Less severe (but, unfortunately, more common) side effects of Viagra include: flushing, dyspepsia, minor vision impairments, headache and nasal congestion.

It's important to remember that some substances may interact with Sildenafil making its concentration in your system increase over time. This, consequently, increases the risk of suffering from various side effects. Don't take Viagra together with erythromycin and cimetidine, don't wash it down with grapefruit juice or eat grapefruits when you are taking Viagra. And, of course, never take Viagra along with other ED medications unless advised to do so by your doctor. Only a qualified healthcare provider will be able to calculate a safe dose of mixed ED meds for you.

Is Viagra safe when you are taking it in full accordance with all of the above rules and with your doctor's recommendations? Indeed, it is – as safe as other medications or, perhaps, even safer. But is it safe when you are not following the rules? No, it's definitely not. Please, don't put your health at risk. Play by the rules and enjoy both perfect sex and perfectly healthy life!

Levitra vs Viagra

Frankly speaking, Viagra vs Levitra comparison is not going to be as interesting as that of Cialis and Viagra or Cialis and Levitra – simply because the active ingredients in Viagra and Levitra are almost identical to each other. Hence, all of the features that these two meds offer are almost identical too. The prices both meds are sold at in brick-and-mortar pharmacies fluctuate around $280-300 for a pack of 10 tablets. The duration of effect totals 4-6 hours. Even the side effects are very similar – however, if you had unpleasant side effects when using Viagra, it doesn't mean that you can't take Levitra. The possibility that you will experience adverse effects when taking one med but tolerate the other one perfectly is always very high.

Neither Viagra nor Levitra can be taken with alcohol or grapefruit or grapefruit juice. You can accompany Levitra with a hearty meal though while Viagra works best when taken on an empty stomach. According to customers' reviews, Levitra has somewhat shorter reaction time – even though the official package inserts tell you to take Levitra 60 minutes before sexual activity and Viagra – 30 to 120 minutes before sex.

The bottom line for Levitra vs Viagra comparison is the following: these two meds are so similar you should consider trying both of them on separate occasions to see, which one works best for you.

When returning to Viagra vs Cialis vs Levitra battle, the outcome seems obvious – Cialis works faster, stays effective for longer periods of time, has fewer side effects and gives you erections even when taken along with fatty food or a little alcohol. It is a little more expensive, however, which prevents it from seizing the flawless victory in this battle of three.

Nevertheless, we would conclude that it's all not as easy as it seems to be from the first sight. The final deciding factor would always be you and the way you feel after taking Viagra, Levitra or Cialis. There's always a possibility that your body won't tolerate Cialis but respond perfectly to Viagra or Levitra. Such cases are actually reported in chats and on message boards all over the Internet – along with exactly the opposite ones. Thus, take our little overview of the three ED meds into account – but make the final decision based on your body's response to the medication.
