Erectile dysfunction more popularly known as impotence is a condition wherein a man has a hard time getting and maintaining an erection. There are several contributing factors to the development of erectile dysfunction or ED, but the most common of which is the narrowing of the arteries that flow directly to the penis.

Viagra’s active ingredient, Sildenafil works by preventing the actions of normal chemicals found in the body, called phosphodiesterase type-5. This helps in widening and relaxing the blood vessels which in turn improves the blood flow to the penile region following sexual stimulation. This action helps in maintaining an erection that facilitates sexual intercourse.

Sildenafil is only available with prescription from a doctor. There are non-branded or generic tablets of sildenafil that are made available online. Viagra on the other hand may only be prescribed for men suffering from erectile dysfunction as a result of medical conditions.

Another brand of sildenafil available to the buying public is Revatio. The indication for Revatio is for a totally different condition called pulmonary hypertension or PAH. If used by men with erectile dysfunction, it will not have the same effect as Viagra.

Reminders before taking sildenafil

There are some medications that are not suitable for people with certain medical conditions. There are also cases wherein medications may only be used with utmost care and caution. For these reasons, it is best to notify your doctor of medications that you are taking before taking Viagra. .

  • Men with any disease, injury, or deformity of the penis.
  • Men with existing heart condition, or blood vessel disease or illness.
  • Men suffering from eye condition that may cause loss of vision.
  • Men diagnosed with kidney disease or liver problems.
  • Men with low blood pressure or angina.
  • Men who have suffered from stroke or heart attacks.
  • Men with bleeding problems such as gastrointestinal ulcers.
  • Men diagnosed with sickle cell disease.
  • Men with bone marrow cancer and leukemia.
  • Men who are taking any other medications to treat other medical conditions. Medications include those that are available without prescription, such as recreational drugs called poppers, dietary supplements, herbal medications, and complementary medicine.
  • Men who have allergic reaction to certain drugs.

How to take sildenafil for erectile dysfunction

  • Before taking sildenafil, it is wise to read the manufacturer’s printed information. Information leaflet of sildenafil will give users knowledge about the tablets and will give them information of the side effects that may occur while taking Viagra.
  • Take sildenafil as per instruction of your doctor. It is meant to be taken before sexual intercourse, and should never be use on a daily basis. Ideally, Viagra should be taken one hour before planned sexual intercourse. The tablet will be effective up to five hours after intake. Viagra can be taken with or without food, but if you just took a high-fat meal, the desired effect will kick in at a later time.
  • Viagra comes in three strengths, namely 25 mg, 50 mg, and 100 mg tablets. Normally, doctors will prescribe 50 mg tablets for starters, but this may be changed depending on how your body reacts to the drug. When dispensing, make sure that you collect the prescription with the right dosage to avoid side effects and adverse reactions.
  • For those who will be supplied with a brand of tablet called Nipatra, bear in mind that these are chewables that need to be chewed prior to swallowing it.
  • Never take more than one dose of Viagra in any 24-hour period.

Optimizing Viagra use

  • You and your partner will need to engage in foreplay, just as you would even without taking medication for erectile dysfunction. Viagra will not cause erection without sexual stimulation.
  • Never drink large amounts of alcohol before taking sildenafil. Excessive amounts of alcohol can reduce the body’s ability to get and maintain erection. This can prevent you from getting the desirable effects from taking the tablet.
  • It is highly advised to not take grapefruit juice in combination with sildenafil. Grapefruit features a chemical that increases the amount of sildenafil in the bloodstream which can result in stronger and worse side effects.
  • Make sure to keep regular appointments with your doctor to ensure that you are progressing nicely with intake. If you feel that the tablet dosage is too strong for you, you should discuss this with your doctor. If the tablet is weak and does not give you the desired effects you should report this right away so they can prescribe you with the right dosage.
  • Never use sildenafil if you are taking any other product that treat erectile dysfunction. Simultaneous use of sildenafil with other ED treatments such as Levitra and Cialis is contraindicated.

Can Viagra intake cause more problems?

Along with its desirable effects, most medications may also cause unwanted side effects, but not all of its users suffer from them. The unwanted side effects most often disappear as the body adjusts to Viagra. However this is the case, it is stil best to check in with your doctor or pharmacist if any of the side effects persist or become troublesome:

  • Headache: Make sure to ask your pharmacist to prescribe a painkiller that is safe and can manage this symptom.
  • Flushing of the face, nausea, indigestion, and stuffy nose: All of these symptoms are felt during the first few intake of Viagra. They will soon pass as the body adjusts to the effects of Viagra.
  • Dizziness, vision changes such as blurry vision and color distortion: If any of these symptoms occur, never operate heavy machinery or drive a car until your sense of sight returns back to normal.

If the erection lasts for more than four hours, or once you feel chest pains or sudden loss of vision, you need to contact your doctor immediately for emergency care.

If you suffer from any other symptoms which you think may be caused by the tablets, make sure to speak with your doctor or pharmacist for first aid measures.
