Popular questions about Viagra

Viagra is a well-known drug that helps men fight erectile dysfunction. However, there are many questions and myths surrounding it. In this comprehensive article, we will answer the most popular questions about Viagra to provide you with complete and reliable information.

What is Viagra and how does it work?

Viagra or sidenafil is a medication used to treat erectile dysfunction (ED), also known as impotence. ED is the inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse.

Mechanism of action of Viagra:

Viagra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. To understand how it works, you need to understand the physiology of erection.

When a man is sexually aroused, signals are activated in the brain that are sent to the nerves in the penis .
Release of nitric oxide These nerve signals cause the release of nitric oxide (NO) in the corpora cavernosa of the penis (the spongy tissue that fills with blood during an erection).
Increased cGMP levels: Nitric oxide activates the enzyme guanylate cyclase, which increases the production of cyclic guanosine monophosphate (cGMP).
Smooth muscle relaxation: cGMP relaxes the smooth muscles of the corpora cavernosa and arteries of the penis.
Blood Flow: Relaxing the muscles allows more blood to flow into the penis, resulting in an erection.
PDE5 Action: The enzyme phosphodiesterase type 5 (PDE5) breaks down cGMP, which results in decreased blood flow and loss of erection.

How does Viagra work?

Viagra inhibits (blocks) the action of PDE5. By blocking PDE5, Viagra prevents the breakdown of cGMP. This means that cGMP remains active longer, which promotes prolonged smooth muscle relaxation and increased blood flow to the penis in response to sexual arousal.

It is important to understand: Viagra does not automatically cause an erection. It enhances the body’s natural response to sexual arousal. That is, for Viagra to work, a man must be sexually stimulated.

What forms of Viagra are available and what dosages are available?

Viagra is available in a variety of forms and dosages to meet individual patient needs.

Release forms:

Film-coated tablets: This is the most common form of Viagra. The tablets are usually blue and diamond-shaped.
Soluble Tablets These tablets dissolve in the mouth, making them convenient for those who have difficulty swallowing regular tablets.
Chewable tablets These tablets also dissolve in the mouth and come in a variety of flavors.
Oral gel (oral gel): The gel is taken directly from the sachet and may be a convenient option for some men.

Dosage:

Viagra is available in the following dosages:

25 mg: The lowest dose, usually prescribed for men taking Viagra for the first time or with mild ED.
50 mg: Average dose, most common and effective for most men.
100 mg: The highest dose, intended for men who are not helped by the 50 mg dose. Use with caution due to the increased risk of side effects.

Initial Dose Doctors usually recommend starting with a dose of 50 mg. Depending on the effectiveness and tolerability, the dose can be adjusted. It is important not to change the dose without consulting a doctor.

How to take Viagra correctly?

Using Viagra correctly is key to achieving maximum effectiveness and minimizing the risk of side effects.

Basic rules for taking Viagra:

Take 30-60 minutes before sexual activity: Viagra takes about 30-60 minutes to start working. Taking the drug beforehand will allow it to be fully absorbed and begin working before sexual activity.
Do not take more than one dose per day: The recommended frequency of taking Viagra is no more than once per day. Repeated use within 24 hours may increase the risk of side effects.
Take on an empty stomach or with a light meal: Fatty and heavy meals can slow the absorption of Viagra, which can delay the onset of action of the drug and reduce its effectiveness. A light snack should not affect the action of the drug.
Avoid Alcohol: Alcohol can increase Viagra’s side effects, such as dizziness and headaches, and may also make it harder to get an erection. It is recommended that you avoid drinking alcohol while taking Viagra.
Sexual stimulation is necessary: As already noted, Viagra does not automatically cause an erection. In order for the drug to work, sexual stimulation is necessary – foreplay, erotic fantasies, etc.

Important: Follow your doctor’s instructions and the instructions for the drug. If you have any doubts about the correct use of Viagra, consult your doctor or pharmacist.

How long does Viagra work and how long does the effect last?

The duration of action of Viagra is an important aspect for men planning sexual relations.

Viagra usually begins to work within 30-60 minutes of taking it. Some men may experience effects sooner, while others may experience effects later. Factors that influence the onset of action include individual body characteristics, dosage, method of administration (whether on an empty stomach or not), and psychological state.

Duration of Action The effects of Viagra typically last between 3 and 5 hours. This does not mean that you will have an erection during this entire time. It does mean that during this period of time you will be more able to achieve an erection in response to sexual stimulation.

Factors affecting duration of action:

Dosage: A higher dose of Viagra may have a slightly longer duration of action, but also increases the risk of side effects.
Metabolism: Individual metabolic patterns affect how quickly the body breaks down and eliminates the drug.
Age and general health: In older men and men with certain medical conditions (such as liver or kidney disease), Viagra may take longer to work.
Other medications: Interactions with other medications may affect how long Viagra lasts.

Important: The duration of action of Viagra is an average. Individual experience may vary. If you have questions about the duration of action of Viagra in your case, consult your doctor.

What side effects can Viagra cause?

Like any medication, Viagra can cause side effects. Most are mild and temporary, but it is important to be aware of the possible risks.

The most common side effects of Viagra (usually mild and temporary) are:

Headache: The most common side effect, often mild to moderate.
Facial flushing (blood flow): a feeling of warmth and redness of the skin of the face, neck and chest.
Nasal congestion: Mild nasal congestion.
Visual disturbances: Temporary changes in vision such as blurring, sensitivity to light, or changes in color perception (usually a slight blue tint).
Stomach upset: Mild stomach discomfort, heartburn, or nausea.

Rare but serious side effects (require immediate medical attention):

Priapism: A prolonged and painful erection (more than 4 hours), which can lead to damage to the penile tissue. If priapism occurs, seek immediate medical attention!
Sudden loss of vision or hearing: Very rare but serious side effects. If you experience sudden loss of vision or hearing, stop taking Viagra immediately and contact your doctor!
Cardiovascular problems In men with heart disease, Viagra may increase the risk of heart attack, stroke, or irregular heartbeat. Tell your doctor about any cardiovascular problems before taking Viagra!
Allergic reactions: Rarely, allergic reactions such as rash, itching, swelling of the face, tongue or throat, difficulty breathing are possible. If symptoms of allergy occur, seek help immediately!

Contraindications to taking Viagra: Who should not take Viagra?

Viagra is not suitable for all men. There are certain conditions and situations when taking Viagra is contraindicated or requires special caution.

Main contraindications:

Allergy to sidenafil or any other component of the drug: If you have previously had an allergic reaction to Viagra or other PDE5 inhibitors, then taking Viagra is contraindicated.
Taking nitrates: Nitrates are a medicine used to treat angina (chest pain). The combination of Viagra and nitrates can cause a sudden and dangerous drop in blood pressure. Never take Viagra if you are taking nitrates! Nitrates include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
Severe Cardiovascular Disease: Men with serious heart problems such as unstable angina, severe heart failure, or a recent heart attack or stroke should not take Viagra because of the increased risk of heart complications.
Severe liver impairment: Men with severe liver impairment may have slower metabolism of Viagra, which can lead to a build-up of the drug in the body and an increased risk of side effects.
Severe kidney failure: Like liver failure, severe kidney failure can affect how well Viagra is eliminated from the body.
Low blood pressure (hypotension): Viagra may further lower blood pressure. Men with hypotension should avoid taking Viagra or take it with caution and under close supervision.
Certain eye conditions, such as retinitis pigmentosa: Men with this rare inherited disorder of the retina may have an increased risk of vision-related side effects.
Women and Children: Viagra is intended for men only and is not intended for use in women or children.

Special reservations:

Before you start taking Viagra, it is important to tell your doctor about all existing medical conditions and medications you are taking. Particular attention should be paid to:

Cardiovascular diseases (angina pectoris, arrhythmia, heart failure, history of myocardial infarction, history of stroke, hypertension, hypotension).
Liver and kidney disease.
Blood diseases such as leukemia or multiple myeloma.
Peptic ulcer of the stomach or duodenum.
Deformation of the penis (Peyronie’s disease).
History of priapism.

Can you take Viagra with alcohol?

It is not recommended to drink alcohol while taking Viagra. Although small amounts of alcohol are usually not contraindicated, excessive alcohol consumption can increase the risk of side effects and reduce the effectiveness of Viagra.

Possible negative effects of combining Viagra and alcohol:

Increased side effects: Alcohol and Viagra can both lower blood pressure. Their combination can lead to a sharp drop in blood pressure, which manifests itself as dizziness, headache, weakness, and fainting.
Reduced effectiveness of Viagra: Alcohol can make erections harder, which can partially or completely negate the effects of Viagra.
Dehydration: Alcohol has a diuretic effect, which can lead to dehydration. Dehydration can worsen the side effects of Viagra.
Risk of cardiovascular complications: In men with heart disease, combining alcohol and Viagra may increase the risk of heart complications.

Recommendation: For maximum effectiveness and safety of Viagra, it is recommended to abstain from alcohol or limit it to a minimum amount when taking the drug.
