What is it?
Viagra (manufactured by Pfizer) is a drug to treat erectile dysfunction. Viagra’s main ingredient is sildenafil, which is a class of drug known as a PDE-5 inhibitor. Viagra was discovered when scientists were looking for a treatment to improve blood flow, and improved erections just happened to be a side-effect of their new medicine. Viagra tablets are blue, with a rounded diamond shape. They say ‘Pfizer’ on one side and either ‘VGR25’, ‘VGR50’ or ‘VGR100’ on the other side.
How should I take Viagra?
Take Viagra pills exactly as it is prescribed for you. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Viagra is usually taken only when needed, 30 minutes to 1 hour before sexual activity. You may take it up to 4 hours before sexual activity. Do not take Viagra more than once per day.
Viagra can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor’s instructions.
During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of Viagra.
You should not take Viagra pfizer if you are already taking any nitrate drug for heart problems or chest pain, as a combination of both drugs can lead to a serious and sudden decrease in blood pressure. Viagra should not be taken by people with certain medical conditions. You should inform your doctor if you have any heart rhythm problems or heart disease, high or low blood pressure, kidney or liver disease, coronary heart disease, and blood cell disorders such as leukemia, sickle cell anemia, or multiple myeloma. Consult your doctor if you have history of heart attack, congestive heart failure, or you have a bleeding disorder such as hemophilia. Viagra may not be the ideal drug for men with retinitis pigmentosa or Peyronie’s disease. Since it can cause side effects, you should buy Viagra only after getting the prescription from your doctor.
Proper storage of Viagra:

Use of Viagra is contraindicated in patients who use any form of organic nitrates or nitrites. In such patients, Viagra can cause hypotension in patients. Patients who are taking any form of alpha-blocker also need to take care and should have adjusted to their alpha-blocking therapy before starting treatment. People who use any form of Ritonavir based drugs or CYP3A4 inhibitors need to start with 25mg of dosage. Patients who are older than 65 years of age also need to start with 25mg as higher dosages can end up making a patient experience high levels of Viagra in blood plasma.
