Buy Canadian Pharmacy Viagra Online

Viagra is a medication, which first comes to the mind of men when they notice problems with erection. The reason for this is the high efficacy and safety of this preparation, which made a revolution in the therapy of erectile dysfunction in 1998 when it was approved for medical use. Until nowadays, this drug keeps the leadership among ED pills and is the most often purchased remedy for male sexual inability.

Since 2017, Viagra became available as a generic. Since that time, men have trouble choosing between the brand and generic medicine, as not all of them know the difference between the two.

Viagra. Composition. Action. Indications

The active substance of Viagra tablets is sildenafil citrate. This is a drug from the class of PDE5 inhibitors, which acts by relaxing the smooth muscle tissue of the cavernous bodies of the penis and dilating the penile blood vessels. This enhances the inflow of blood to the pelvis, allowing the organ to fill with enough blood for getting a firm and durable erection.

The vasodilatory effect of sildenafil spreads not only on the genitals but also on the lungs. The dilation of the lung arteries improves the circulation of blood in the lungs, promoting better oxygenation of the blood. Such an effect is beneficial for people suffering from a severe lung disorder called pulmonary arterial hypertension (PAH). This medical condition is incurable, yet the intake of sildenafil allows such patients to improve the quality of life.

Sildenafil for the therapy of PAH is produced under the brand name Revatio. The only difference between Viagra and Revatio is the concentration of the active substance. The latter contains either 10 mg or 20 mg of sildenafil, whereas the amounts of the active component in Viagra range from 25 mg to 100 mg.

Brand or Generic? What to Choose?

Generic Viagra is a preparation shrouded in a myth that has been spreadby the manufacturer of the brand name Viagra Pfizer. The company claimed to have found printer ink among ingredients in Viagra generic. However, this hasn’t been proven by any official sources.

In fact, the only differences between the brand and generic medication are their names, package, and pill appearance. They also differ in price due to the lack of the need for a generic medication to be patented. The name of the active substance and its concentrations are the same for both drug versions. Their rates of efficacy and safety are similar. Therefore, when buying a generic, you save money without compromising the quality of the drug.

How to Take Viagra?

Viagra, or sildenafil, belongs to prescription substances because of the contraindications and precautions for use it has. To minimize the risks for unwanted reactions, you should consult a doctor before taking Viagra to treat erectile dysfunction (ED). A medical professional will also help to choose the correct dosage based on your medical conditions. Here is some general advice on how to take Viagra tablets:

• Ingest a pill only if you plan to have sexual intercourse;
• Take the tablet at least 30 – 60 minutes before coitus;
• Use Viagra on an empty stomach to get a better effect;
• Never take more than 100 mg pill of Viagra per 24 hours;
• You have to feel sexually excited and receive adequate sexual stimulation to make the drug come into effect.

The effects of Viagra last for 4 – 5 hours, yet some studies claim it remains effective for up to 12 hours in more than 70% of users.

Who Shouldn’t Take Viagra?

When used as a treatment for ED, sildenafil is intended for adult men only. The preparation has some precautions and contraindications for use, which should be discussed with your healthcare provider. Tell your doctor if you suffer or have suffered the following health issues:

• Severe heart problems, including a recent heart attack;
• High blood pressure;
• Allergy to sildenafil or excipients;
• Severe liver or renal impairment;
• NAION;
• Blood cell disease;
• An active stomach ulcer;
• Penile deformities;
• A history of painful erection.

The use of the drug is not recommended due to the high risk of a severe drop in blood pressure in patients who are already taking organic nitrates or riociguat. Caution and dose adjustment is required if a man is also using protease inhibitors, alpha-blockers, azole antifungals, macrolide antibiotics, and some other medications.

You should exclude grapefruit juice from your diet when on Viagra as their interaction may lead to the symptoms of a drug overdose.

What Are the Possible Adverse Effects of Viagra?

Viagra is a well-tolerated drug. The manifestations of its side effects are usually mild or moderate and resolve on their own within several hours. The most commonly reported adverse reactions to Viagra are:

• Upset stomach;
• Facial flushing;
• Nasal stuffiness;
• Light dizziness;
• Headache;
• Light sensitivity;
• Blurred vision.

Severe reactions to the drug are rare and need medical attention. Call your doctor or go to the nearest clinic if you develop a painful erection, chest pain, sudden vision loss, nausea, vomiting, or signs of an allergic reaction (itchy rash, swelling of the face, tongue, and throat, trouble breathing). Although Viagra is considered a safe drug, it still needs caution when used, so be careful and follow your doctor’s advice to make your treatment experience positive.
