A friend of mine was having ED issues. The Urologist he saw prescribed viagra. The Urologist also told him that drinking grapefruit juice would really enhance the effect the the viagra. Anyone have any experience of using viagra and grapefruit juice?

 

Researchers found that the absorption of Viagra increased by 23% when taken with grapefruit juice instead of water. Grapefruit juice also delayed the absorption of Viagra. This latter point is important because Viagra is supposed to be taken one hour before sex, and taking the drug with grapefruit juice may result in disappointment for some users of Viagra.

The grapefruit juice used in this study was white juice and supplied by Döhler-Euro Citrus NBI, GmbH. Other brands, types and doses of grapefruit juice may have different effects. The researchers suggest that the combination of Viagra and grapefruit juice be "avoided."

Men who use protease inhibitors are usually prescribed less-than-normal doses of Viagra because protease inhibitors can raise levels of Viagra several times greater than normal, which can cause dangerous side effects. Therefore, men who use protease inhibitors and Viagra may wish to also avoid taking Viagra with grapefruit juice.


So, apparently you absorb more, but also more slowly. And grapefruit juice with other drugs can cause serious side effects, so beware.

 

Freethinker is right and grapefruit juice inhibits the uptake of lots of drugs and medicines!

Dangerous. Could drop his blood pressure. Many medicines interact with grapefruit. It's called the grapefruit effect.

 

Your friend, huh?

 

Thanks Freethinker! I shared your post with my buddy. He went online and learned a lot. He's not to happy with the advise his Urologist gave him. He going to get a second opinion about his problem. Thanks
