Viagra works by increasing blood flow to the erectile tissue of the penis, which helps achieve or maintain erections. Viagra improves potency when a man is already sexually stimulated, but does not provide sexual stimulation. Viagra does not work without sexual stimulation.
During sexual stimulation, nitric oxide is released by the nervous system in the erectile tissue of the penis. Nitric oxide stimulates an enzyme that produces the messenger substance guanosine monophosphate (cGMP).
cGMP causes the arteries in the penis to dilate, allowing the arteries and erectile tissue to fill with blood. This is how an erection occurs.
Viagra is suitable for oral use. The recommended dose for adults is 50 mg, which should be taken as needed one hour before sexual intercourse. Depending on the effectiveness and tolerability, the daily dose can be increased to 100 mg or reduced to 25 mg. The maximum recommended dose is 100 mg.
The frequency of Viagra intake is once a day. To speed up the effects of Viagra, a blue pill should be taken on an empty stomach.
If you are over 65 years old or have mild or moderate renal impairment (creatinine clearance 30-80 ml/min), no dose adjustment is required.
In case of severe renal insufficiency (creatinine clearance <30 ml/min) or liver failure, the starting dose of Viagra is 25 mg. Depending on the effectiveness and tolerability of the drug, the dose can be increased to 50 and 100 mg.

VIAGRA is not indicated for the treatment of women.
Alcohol consumption should be avoided
Alcohol interacts with Viagra to produce side effects, especially when consumed in excessive amounts. When alcohol is consumed, it usually stops the natural erection process. Therefore, alcohol is discouraged.
Because Viagra tablets are taken as needed, you are unlikely to miss a Viagra dose.
Serious side effects can occur after taking excessively high doses. If you experience severe side effects, seek medical help immediately.
Symptoms of overdose include but are not limited to vomiting, blurred vision, papilledema, optic neuropathy, tachycardia, persistent priapism, diarrhea, etc.
There is a risk of serious interactions. Therefore, regular medical monitoring is required.
Because of the interactions, taking Viagra at the same time as some medications is contraindicated.
Priapism
Es wurde berichtet, dass die Männer nach der Einnahme von Viagra eine Dauererektion (d.h. mehr als 4 Stunden) hatten. Dies trat selten auf. Wenn die Dauererektion jedoch auftritt und nicht rechtzeitig behandelt wird, kann es zu dauerhaften zu dauerhafter Beschädigung des Penis kommen, einschließlich der Impotenz. Im Fall von der Dauererektion sollte der Arzt aufgesucht werden.
Headache
Dizziness
Food does not affect the effects of the drug.
Viagra can be taken regardless of meals. Taking Viagra after a high-fat meal can slow down its onset of action.
The medicinal product must be stored away from heat.
Store in the original package in order to protect from light and moisture.

Taking Viagra is an effective method of treating impotence in adult men. Viagra pills have been used to treat erectile dysfunction for over two decades and have proven to be very effective in more than 80 percent of men.
By taking the sexual enhancer Viagra, you may be able to:
Viagra is available in local pharmacies in Britain. The usual way to obtain it is to visit a doctor who will prescribe the valid prescription. Making an appointment with the doctor is embarrassing for many patients because they should discuss such an intimate issue with the doctor.
Fortunately, there is a second way to get Viagra. The men with ED can order the blue pills online from a mail order pharmacy.
While it's convenient to buy medications over the counter, this isn't typically an option for prescription drugs like Viagra. To buy a sexual enhancer in a pharmacy, you usually need a doctor's prescription. This is because Viagra can be dangerous when taken by men who have the contraindications for taking it.
To get a prescription for Viagra or any other sexual enhancer, you should see your family doctor or a urologist. Alternatively, you can order Viagra online from an accredited online doctor service.
There are many internet pharmacies that sell Viagra online. However, since not all of these pharmacies sell this sexual enhancer legally and safely, it is important to know which pharmacy you can trust. For this reason, when choosing the mail-order pharmacy, you should not only consider the price, but also whether selected pharmacy is accredited and whether they follow the right procedures.
Getting Viagra from the comfort of your own home is the main reason for buying it online. It is not necessary to consult a doctor. Also, you don't have to go to the pharmacy, which saves a lot of your time. When you buy Viagra online , you can skip all of these steps and have your medication delivered to your doorstep at your convenience.
The price for Viagra is standardized in the stationary pharmacies in Britain. So 4 tablets cost about 50 euros.
The Viagra price offered by each mail order pharmacy varies as each provider sets their own prices. The price depends on the package size and dosage.
Some online pharmacies sell Viagra with online prescription, so you have to pay a prescription fee in addition.

If Viagra doesn't work for you, alternative medications are available. You can try Cialis (Tadalafil), Levitra (Vardenafil), or Spedra (Avanafil). Cialis works for up to 36 hours and can be taken as a once-daily tablet (2.5 mg or 5 mg) or as needed (10 mg or 20 mg). Levitra is available in strengths of 5 mg, 10 mg and 20 mg. It has been shown to be effective across a wide range of ages and in men with conditions such as high blood pressure, diabetes, depression and high cholesterol. Spedra is available in strengths of 50 mg, 100 mg, and 200 mg. It has been shown to work well in men with erectile dysfunction caused by type 1 and type 2 diabetes. Spedra can start working within 15 to 30 minutes of taking the dose - this is faster than Viagra, Levitra or Cialis.
There are also a number of non-prescription alternatives for treating erectile dysfunction such as:
From time to time I suffer from erectile dysfunction. I reported this to my urologist, who then advised me to take 50mg of Viagra before planning to have intercourse. This works great. Viagra works after about 30 minutes and has an effect of almost 5 hours.
