What Is Sildenafil Citrate?

Sildenafil Citrate, a vasodilator, is an oral medication indicated to treat erectile dysfunction (ED). ED means you cannot get or keep an erection, and sildenafil citrate works by increasing blow flow to the penis. Sildenafil is sometimes prescribed off-label to treat other medical conditions, such as Raynaud’s disease (a disease that causes fingers and toes to become cold and numb) and prostate cancer. It is also indicated to treat pulmonary hypertension, which is a form of high blood pressure that affects the arteries in the lung or heart.

Dosage and Side Effects

Viagra is a pill that is usually prescribed in the following dosages: 25 mg, 50 mg or 100 mg. Usually, the recommended dose is 50 mg taken around an hour prior to sexual activity, but it can be effective if taken anywhere from 30 minutes to four hours before sex. You should not take more than one Viagra per day.

Side effects associated with sildenafil citrate may include:

  • Headache
  • Diarrhea and upset stomach
  • Heartburn
  • Runny or stuffy nose
  • Nosebleed
  • Trouble falling or staying asleep
  • Sensitivity to light
  • Feelings of tingling or numbness in the arms, hands, feet or legs
  • Flushing
  • Changes in vision – most notably, the inability to tell the difference between green and blue

You should talk to your doctor right away if any of these symptoms become severe or will not go away. Signs of an allergic reaction that require immediate medical attention include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat.

Generic Viagra

Pfizer manufactures brand name Viagra, and its patent protecting the drug from the generic competition is set to expire in April 2020. Despite this, Teva Pharmaceuticals was allowed to launch generic Viagra in December of 2017. There are two generic versions available. As far as payment is concerned, the current price for brand name Viagra is about $70 per pill. On the generic side, you can expect to pay between $35 and $40 per pill without a discount for Viagra.


Kamagra is a medication sold as a treatment for ED. It is manufactured in India and sold online without the need for a prescription. Although men may view this as a cheap alternative to Viagra, Cialis or another ED medication, it is not regulated by the FDA and should therefore not be considered safe.
