Sildenafil instructions for use, how to take?

Sildenafil is a popular drug used to treat erectile dysfunction in men. It helps to achieve and maintain an erection during sexual stimulation by improving blood circulation in the penis.

The drug belongs to the group of phosphodiesterase type 5 (PDE-5) inhibitors and is commonly used under brand names such as Viagra.

Indications for use of Sildenafil

Sildenafil is indicated for the treatment of erectile dysfunction, characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. The drug works only in the presence of sexual stimulation, providing a natural erection mechanism.

How does Sildenafil work?

Sildenafil works by blocking the PDE-5 enzyme that breaks down cyclic guanosine monophosphate (cGMP). CGMP is responsible for the relaxation of smooth muscles in the walls of the blood vessels of the penis, which increases blood circulation and leads to an erection. Taking Sildenafil increases the level of cGMP, ensuring a long-lasting erection.

How to take Sildenafil?

Dosage : The standard starting dose is 50 mg, but the doctor can prescribe an individual dosage from 25 to 100 mg depending on the needs of the patient.
Time of administration : The drug should be taken 30-60 minutes before planned sexual activity. The effect of Sildenafil can last up to 4-6 hours.
Method of administration : The tablet is swallowed with water. It can be taken both on an empty stomach and after a meal. However, eating fatty food can delay the onset of the drug.
Frequency of administration : Do not take more than one tablet per day. Follow your doctor's recommendations for frequency of use.

Contraindications to taking Sildenafil

The drug is not suitable for all patients. The main contraindications include:

Taking nitrates (medicines for the cardiovascular system), as simultaneous use can lead to a dangerous decrease in blood pressure.
Serious diseases of the heart and blood vessels, stroke or myocardial infarction in the anamnesis.
Allergy to sildenafil or other components of the drug.
Severe forms of kidney or liver failure.
Congenital diseases of the retina, such as retinitis pigmentosa.

Sildenafil has side effects

Like all medicines, Sildenafil can cause side effects. The most common of them include:

Headache
Redness of the face
Nasal congestion
Dizziness
Digestive disorders
Temporary vision changes, such as blue or blurred vision

If you experience serious side effects such as chest pain, a sudden drop in blood pressure, or an erection lasting more than 4 hours (priapism), contact your doctor immediately.

Sildenafil interactions with other medications

Before taking Sildenafil, be sure to consult your doctor if you are taking other medications. Some of them can affect the effect of the drug or increase the risk of side effects:

Nitrates : Concomitant use with nitrates can cause a sharp drop in blood pressure.
Antihypertensive drugs : Taking together with drugs for high blood pressure requires additional attention due to the possibility of a sharp decrease in blood pressure.
Antibiotics and antifungals : Some of them can increase the concentration of Sildenafil in the blood, which increases the risk of side effects.

Special recommendations

Alcohol : Drinking alcohol can reduce the effectiveness of Sildenafil and increase the risk of side effects such as dizziness or headache.
Driving and operating machinery : Sildenafil may cause temporary visual disturbances or dizziness, so be careful when driving or operating machinery.
