It might be tempting to start at the lowest dose—who wants to take more medication than they need?—but the reality is, it might not be enough to treat the problem. And that can leave guys frustrated.
“For the majority of men who come in really complaining about ED, if it’s going to work, it’s going to work at the higher dose,” says Dr. Rajfer.
Exception: If you have other health conditions, like hypertension, diabetes, or high cholesterol, your doctor will probably start you on a lower dose to make sure you can tolerate the medication, he says. Otherwise, ask your doc if your prescription is for the max.
If you’ve just had a big dinner, a romp in the bedroom right after might not be in the cards. Over 20 percent of men in the study made the mistake of taking Viagra or Levitra too soon after eating.
That’s a major problem. Those two drugs work best on an empty stomach, so you need to wait at least 2 to 3 hours after a full meal to take them, says Dr. Rajfer.
“If you have food in your stomach with those drugs, only half the drug gets absorbed,” he explains. “So if someone whose penis requires 100 milligrams (mg) takes that 100 mg with food in his stomach, he is really only getting a 50 mg dose.”
Just remember that’s only true for Viagra or Levitra. Cialis, on the other hand, doesn’t carry any restriction in regards to when you should chow down.
