Let's dive in.

What Is Sildenafil and How Does It Work?

Sildenafil (Viagra) is a medication that is used to treat erectile dysfunction (formerly referred to as impotence) in men. It's sold under the popular brand name Viagra. It's also used to help adults that suffer from pulmonary arterial hypertension (PAH) or high blood pressure. 

To understand how sildenafil helps erectile dysfunction, it's important to understand why some men experience ED in the first place. 

When a man is aroused through sensory and mental stimulation, blood flows into the penile arteries. For the blood to enter, certain muscles in the penis must relax. The blood then gets trapped due to the high pressure in the penis, which creates an erection. 

Erectile dysfunction happens when not enough blood enters the penis or when the penis can't maintain the pressure to keep the blood there. 

There are many contributing factors to why a man might experience ED, including but not limited to:

  • High cholesterol
  • High blood sugar (diabetes)
  • High blood pressure
  • Lack of exercise
  • Aging
  • Stress or other emotional reasons
  • Cardiovascular disease
  • Obesity
  • Drugs
  • Excess alcohol
  • Smoking

Sildenafil (Viagra) belongs to a class of medications called phosphodiesterase (PDE5) inhibitors. Other popular ED medications like Cialis or Levitra also fall under these categories.

By blocking enzymes that are a key culprit in erectile dysfunction, it allows your penis to relax and allows blood to flow more easily into the penis. Similarly, sildenafil helps PAH by allowing blood to flow better to the lungs.

It's important to note that sildenafil or other ED medications do not increase sexual desire or cure erectile dysfunction. It is a temporary solution to erectile dysfunction.

How Do You Use Sildenafil?

Before you take sildenafil (generic Viagra), make sure to completely follow your doctor's directions as well as the instructions that come with it. 

Sildenafil comes in pill form and is taken orally. You are to take sildenafil when you need it before sexual activity. The best time to take it is about an hour before you plan on having sex, but you can take it anywhere from 4 hours to 30 minutes before sexual activity. It's good to plan ahead when you will take the pill.

You can take sildenafil with or without food, but keep in mind that eating a large, high-fat meal will probably make it harder for the medication to digest. This means it will probably take longer for the Viagra to work.

What Are the Sildenafil Warnings and Precautions?

Like most other medicines, you should be aware of sildenafil precautions before taking the medicine. 

First, it's important to let your doctor know all medications, vitamins, and herbal supplements you may be taking beforehand. There are certain medications that sildenafil reacts with, including nitrate medicines that are usually prescribed for angina or high blood pressure. These include:

  • Nitroglycerin
  • Isosorbide
  • Imdur®
  • Nitro-Bid®
  • Nitro-Dur®
  • Nitrol® ointment
  • Nitrolingual® spray
  • Nitrostat®
  • Transderm Nitro®

Illegal street drugs such as "poppers" also include nitrates that could cause a sharp drop in blood pressure when mixed with sildenafil.

Sildenafil should not be used with any other medications that are used for ED.

Another sildenafil warning is that it does not protect you against any sexually transmitted disease like HIV or AIDS. You need to be prepared to take other protective measures against STDs.

If you've ever had heart problems, make sure to consult with a doctor before taking sildenafil. It can have serious side effects on patients who have experienced heart problems in the past. 

If you experience any of the following, make sure to seek immediate medical help:

  • Prolonged or painful erection for more than 4 hours
  • Sudden loss of vision in one or both eyes
  • Sudden decrease in hearing or loss of hearing
  • Dizziness or ringing in the ears
  • Blurred vision
  • Confusion
  • Dizziness
  • Faintness
  • Lightheadedness
  • Unusual sweating
  • Unusual weakness

If you take medication for high blood pressure, sildenafil can cause a sharp drop in blood pressure.

Other sildenafil handling precautions include being aware of dehydration when using the medication. This can happen if you are sick with fever, diarrhea, or vomiting. It could cause complications with your heart, kidney, or liver.

  • Have serious heart or liver problems
  • Have low blood pressure
  • Have recently had a stroke or heart attack
