Viagra (Sildenafil)

What is the Viagra (Sildenafil)?

Viagra is a medication prescribed for adult males to treat sexual function problems (impotence or erectile dysfunction). Viagra belongs to the drug class, Phosphodiesterase-5 Enzyme Inhibitors. Along with sexual stimulation, these medications work by relaxing the muscles of the blood vessels and increasing the blood flow to the penis to help a man get and stay erect.

Viagra is not recommended:

  • If you are allergic or have had an allergic reaction to Viagra or ingredients in Viagra.
  • If you are taking medications containing nitrates.
  • For patients under 18 years of age.

What are the Indications for Viagra?

Viagra is approved for the treatment of erectile dysfunction in males 18 years and older.

How is Viagra used?

Storage

Viagra should be stored in the original container at 77°F (25°C) with excursions permitted between 59-86°F (15-30°C).

Keep it out of reach of children.

Instruction

Take Viagra by mouth, as directed by your doctor, preferably without food about one hour before sexual activity. Avoid taking it with a high-fat meal as it can affect how quickly the medicine is absorbed.

Do not take more than one tablet in 24 hours.

Do not change your dosage and take more than what is prescribed. Contact your doctor immediately or seek emergency medical care if you took more than the prescribed dosage.

Dosage

Viagra comes in a blue film-coated diamond-shaped pill form and is available in the following strengths: 25 mg, 50 mg, and 100 mg.

One Viagra tablet should be taken 60 minutes before sexual intercourse, preferably on an empty stomach, but can also be taken 30 minutes to 4 hours beforehand.

Viagra is only recommended to be taken once per day. If you’re planning on engaging in sexual activity more than once throughout the day, you shouldn’t take a pill every time.

If Viagra doesn’t work for you, don’t double up and take another one. If you take more than the recommended dosage, you are at risk for serious effects.

Nitrates

Do not take Viagra if you use any medicines that contain nitrates, including nitroglycerin as it can cause your blood pressure to suddenly drop to an unsafe or life-threatening level and lead to a heart attack or stroke.

Priapism

Priapism is a long-lasting and painful erection. If left untreated, it can damage the tissues in the penis and cause irreversible erectile dysfunction. Please contact your doctor immediately or visit the emergency room if this happens.

Heart conditions

If you suffer from heart disease or have had a heart attack or stroke, please speak to your doctor before taking Viagra. If you take Viagra and experience any chest pains, dizziness, or nausea during sex, please stop immediately and let your doctor know.

Low blood pressure

Viagra can sometimes cause low blood pressure. If you take medicines for high blood pressure, your blood pressure might drop too low. Your doctor might prescribe a dose of Viagra that’s lower than the typical dose.

Sexually Transmitted Diseases

Viagra does not protect you against sexually transmitted diseases (STIs) such as HIV, Hepatitis B, and Syphilis. You should continue to take the necessary precautions to protect yourself against STIs.

Alcohol

Viagra can make you dizzy or cause vision changes. Using alcohol at the same time as Viagra can increase your dizziness. Limit your alcohol intake while using this medication.

Pregnancy and breastfeeding

Viagra is not intended for use by women, and it is therefore not recommended during pregnancy and breastfeeding.

Interactions & Contraindications

Before using Viagra, tell your doctor or pharmacist if you take any:

  • Medicines, especially nitrates, antibiotics, antifungal medicines, medicines for high blood pressure, prostate disorder, heart rhythm, or HIV/Aids.
  • Herbal supplements
  • Vitamins

Guanylate Cyclase (GC) Stimulators

Patients who are using a GC stimulator, such as riociguat, should not use Viagra as it may cause abnormally low blood pressure, already associated with the use of GC stimulators. This can lead to dizziness, fainting, and rarely a heart attack or stroke.
