Sildenafil Prescription

sildenafil prescription

Why is this medication prescribed?

Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Children should not usually take sildenafil, but in some cases, a doctor may decide that sildenafil (Revatio) is the best medication to treat a child's condition. Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.If you are taking sildenafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Sildenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).

How should I use this medicine?

Take this medicine by mouth with a glass of water. Follow the directions on the prescription label. You can take it with or without food. If it upsets your stomach, take it with food. Take your doses at regular intervals about 4 to 6 hours apart. Do not take it more often than directed. Do not stop taking except on your doctor's advice.

How to Take?

Generic Viagra should be prescribed by a doctor or a pharmacist. This will ensure that the active ingredient in the medication will be able to alleviate the issues that you are experiencing, mitigating any adverse side effects. Your doctor will give you a prescription for directions as to how it should be taken for the best results. The pill must be taken at least an hour before coitus or when sex will be expected. It must also be consumed with water to ensure that any acids and fats do not interact with the pill. If you feel that you have overdosed by accident, emergency medical treatment should be sought out immediately. Blurry vision, headaches, an irregular heartbeat are symptoms of an overdose.

How to work?

Sildenafil Citrate works as a PDE5 inhibitor. PDEF5 interacts with the action of cGMP-specific phosphodiesterase type 5 on cyclic GMP in the smooth muscle cells in the penis. It will then relax the muscles, allowing better blood flow to help properly dilate the shaft. Once the medication into the bloodstream, it spreads directly to your circulatory system and into the bloodstream, targeting and disabling the PDEF5 enzyme. Once disabled, blood flow is relaxed, and the penis can achieve erection upon sexual stimuli. It is a well-documented phenomenon, with Sildenafil Citrate being very useful in most scenarios

What are the side effects of sildenafil?

Approximately 15% of persons taking Viagra experience side effects. The most common side effects are:

  • facial flushing (1 in 10),
  • headaches (1 in 6),
  • stomach pain,
  • nasal congestion,
  • nausea,
  • dizziness,
  • rash,
  • urinary tract infections (UTIs)
  • diarrhea, andan inability to differentiate between the colors green and blue.

Dosages

The dosage for Sildenafil Citrate will typically be 25, 50, or 100 mg. The starting dose would typically be in the lower range or 50 mg. This will ensure that your body becomes accustomed to the active ingredient in the medication. Depending on the patient and the type of issues that need to be alleviated, dosages may increase or decrease over time. More than one dosage of Viagra within a 24-hour window is dangerous and should not be done. If you take more than one pill within that time frame, you should seek medical attention to ensure that there arent any dangers of overdosing. You should avoid eating meals that are high in fat before administering Sildenafil Citrate. Foods with a very high-fat content can reduce the effectiveness of the active ingredient.

What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
