Patients often have a misconception that because they’re taking supplements and not pharmaceutical drugs, it’s safe, he said. “There’s still a huge distrust of the pharmaceutical industry in this country,” he said. “So many men believe that if you’re taking a supplement it’s all natural and it has all the good effects and none of the side effects.” Some men may be embarrassed to talk to their doctors about libido or other personal issues. Many people turn to supplements because they don’t have health insurance, said Cohen, who works as a primary care physician.

“I have guys that will bring in a moving box full of 15 to 30 supplements a day and want me to review them with them,” Mills said. Duffy MacKay, senior vice president of dietary supplements at the Consumer Healthcare Products Association, said the way consumers get the products has changed in recent years. “At one point, these types of products were really limited to the dark shadows,” he said. The proliferation of websites selling supplements has made it difficult for regulators to keep pace, he added.

Visual changes, such as blue tinge to vision, sensitivity to light or blurred sight.

But it isn't clear whether these side effects were caused by the medicine or by health conditions that the people already had. Get medical care right away if you take oral ED medicine and have sudden loss of hearing or vision. An erection that doesn't go away on its own. Called priapism, this rare condition can be painful.

12.3 Pharmacokinetics

The companies didn’t immediately respond to requests for comment. Dr. Jesse Mills, a urologist and the director of the men’s clinic at UCLA Health, calls the dietary supplements “truck stop Viagra” and worries that people who get relief from erectile dysfunction with supplements may also be missing opportunities to catch early heart disease. “Erectile dysfunction in a lot of men is a sentinel event that would suggest they have an increased risk of coronary artery disease,” he said. “So if you go and you’re buying a supplement that actually has a pharmaceutical in it that takes care of your ED, you may have missed an opportunity to treat your heart diseases before you drop dead of sildenafil chewable tablets a heart attack.” People taking nitrate medications for heart disease should also be careful, as blood pressure can drop dangerously when they are combined with sildenafil or tadalafil. It’s important to be wary of any product that makes over-the-top claims, Cohen said. Mills said that while there are supplements that have shown some promise in treating erectile dysfunction, such as L-arginine, they are often studied at much higher doses than in over-the-counter products.

Frequently asked questions

Dr. Pieter Cohen, an associate professor at Harvard Medical School who studies the regulation of supplements, described the proliferation of performance supplements as a “hot mess.” Because the FDA doesn’t approve dietary supplements to be sold and marketed in the U.S., it doesn’t regularly test and validate manufacturers’ claims about what’s in them. “The company doesn’t have to inform the FDA before they introduce a product,” he said. “There’s no FDA approval process for any supplements, and companies can just introduce whatever they want to.” The products frequently include words like “Max,” “Miracle” or “Macho” in their names, and they can be easily bought online or in some stores without prescriptions. It’s unclear what’s in them — sometimes packaging lists a variety of vitamins, as well as other ingredients. Cohen said: “If it’s working, we’re concerned that there’s an active pharmaceutical drug that’s not listed on the label, it might cause unknown adverse facts to our health. In this category of sexual enhancement supplements, I recommend that my patients not use them.” Mackey said companies promote herbal ingredients that consumers believe help with vitality and virility, and “then they add the pharmaceutical so that the consumer has whatever sensation or experience that the drug might give them.” Jafari said people should check whether a supplement has been evaluated by a third party, such as the U.S.

Does your performance supplement contain a side of the main ingredient in Viagra? Recent alerts from the Food and Drug Administration have warned that supplements widely marketed to men are testing positive for prescription drugs that could have dangerous side effects. The products are often promoted as “all natural.” Some claim to improve strength and energy, while others are promoted to help sexual performance or virility. Through testing, the FDA detected undeclared ingredients such as sildenafil and tadalafil, the active compounds in the erectile dysfunction prescription medications Viagra or Cialis, in ZoomMax, ZapMax, PeakMax and Vitafer-L Gold. Other drugs that have been found include diclofenac, a pharmaceutical anti-inflammatory that is similar to ibuprofen, and even medications for diabetes. Ultimately, the most important thing to do is find a doctor you trust and can work with to go over any products on the market.
