Viagra 50mg (Sildenafil)

Sildenafil use does come with some side effects to the body along with its desired effects but these symptoms usually disappear as the body adjusts to the medication. The side effects usually show when the patient is just starting to use the drug or when the patient uses high dosage strengths of the medicine. It is important for the patient to provide the doctor with their complete medical history so that the doctor will have a complete understanding of the patient’s health and help them with a method of treatment specifically designed for their health condition. Unless this is done, the patient will not be able to maximize the potential of their Sildenafil treatment and may also suffer from adverse effects from the drug.

Viagra was the brand name by which Sildenafil came to be known. It was released by Pfizer back in 1997 as a treatment for Erectile Dysfunction, a sexual health disorder experienced by half of the population of men over 40. It is a condition where the male’s penis, due to some health factors, can no longer achieve an erection. It is a very concerning problem but because of its nature, not many men are willing to talk about it because of embarrassment and fear of mockery from other men. As a result, men who have this condition begin to experience relationship problems and decreased self-esteem.

The two main causes of this disability are aging and health problems affecting the libido. Alcohol abuse and smoking are also causes of erectile dysfunction which explains why younger generations of men are also experiencing this issue. Stress, depression, anxiety and other psychological/emotional problems are also contributing factors to the development of ED in men at such young ages of twenty to thirty plus years.

But ED is not a dead end and males who have this disorder need not be hopeless. Sildenafil is a drug that counters the effects of Erectile Dysfunction and helps the body to achieve erections by its mechanism of action. Also known as a Phosphodiesterase type 5 (PDE 5) inhibitor, Sildenafil dilates the blood vessels by relaxing the muscles around them. In doing this, Sildenafil allows increased amounts of blood to be circulated in the body. Sildenafil’s effects last for as long as 6 hours which means it will increase the blood flow to the penis for its duration, helping it attain an erection and sustain it for longer periods of time.

Adverse Effects of Viagra

As mentioned earlier, the side effects of using Sildenafil only occurs to the patients when they use the drug for the first time as the body adjusts to the medication and when they take high dosages of the medicine. The common side effects that the patients are expected to experience are nausea, stomach upset, dizziness, vomiting, flushing, back pains, muscle pains, stuffy nose, chest pains, palpitations, vision changes, and heartburn. These side effects are likely to disappear a few hours after using the drug. But in cases of intensifying side effects or side effects lasting for longer periods than usual, patients should immediately seek medical help to get themselves checked.

Nitrate Drugs

Nitrate drugs are to be avoided taken with Sildenafil by patients who chest pains or Angina Pectoris. The chemical reactions produced by the combination of these drugs are dangerous to the health as it lowers the blood pressure. The low blood pressure levels can reach a certain point of decreasing the right amounts of blood flowing to the heart causing a heart attack. Acidic foods are also to be avoided when taking Viagra as it decreases the length of the drug’s efficacy. Grapefruit or grapefruit juice should also be avoided with Sildenafil because it negates the effects of the drug. Grapefruit is also known for boosting the blood pressure levels which is contrary to what Sildenafil accomplishes and taking it when using Viagra might also prolong the duration of the side effects.

Can Viagra be Taken Daily?

Compared to the use of Sildenafil in the treatment of Pulmonary Hypertension, the use of the drug in Erectile Dysfunction is only when needed and a maximum of only one dose every 24 hours.

 Viagra Pills

Unlike Pulmonary Hypertension that needs a constant dosage of Sildenafil to keep the high blood pressures in check, taking Viagra is on a need-only basis and is not required to be regular. Taking this drug more than once in a day puts the person at risk of hypotension, an extreme drop in the blood pressures that will lead to a heart failure.

Taking Viagra When Not Needed

It is unnecessary to take Viagra when not planning to engage in a sexual intercourse with your spouse as this drug is not a cure to be independent of medication but only a drug to help the patient have an erection. Viagra is an expensive drug and taking it when not needed is pointless and will only cost the patient money. PDE 5 inhibitor drugs like Viagra is only for helping males achieve an erection. It does not actually cure the root cause of the condition but only helps in relieving the symptoms. If patients wish to have their natural erections back, there are other types of treatments and therapies that are used but it does not involve Sildenafil.


There are no long-term side effects that come with Sildenafil use as most of them disappear right after the effects of the medication wears off. There might be some adverse effects to using this drug but patients can expect them to decrease in frequency as their bodies adjust to it. Sildenafil cannot be taken daily since this drug is only used when needed. Use of this drug should only be upon the prescription of a physician and should not be used for recreational purposes.
