What Tests Will a Urologist Do if I Have ED?

Herbal products and dietary supplements that claim to be alternatives for ED aren’t regulated by the FDA. So it’s hard to determine which is best or if they’re even safe and effective. If you’re experiencing ED symptoms, it’s a good idea to speak with a healthcare professional about your treatment options. Like all medications, ED medications also carry a risk of side effects. Speak with a healthcare professional about potential side effects and whether these medications would be safe for you to take.

Vitamins and supplements for ED

Phosphodiesterase 5 (PDE5) inhibitors are a class of medications used to treat erectile dysfunction (ED). The available PDE5 inhibitors include sildenafil (Viagra), tadalafil (Cialis), vardenafil (previously sold as Levitra and Staxyn), and avanafil (Stendra). Currently, one PDE5 inhibitor isn’t considered the best for ED. The best ED medication for you depends on many factors such as how often you plan to use it, potential side effects, and how much they cost. Plus, many people alternate between ED medications, depending on their individual needs.

Watch out for side effects

Talk to a healthcare professional about which ED med would be the best choice for you.

What special dietary instructions should I follow?

But most of these are relatively mild and go away after a few hours. ED drugs can make blood pressure temporarily drop, so never use them if you also take medications that contain nitrates. (Nitrates found in food fildena 100mg don't pose a problem.) You also need to be careful if you take any other drugs that lower blood pressure. For example, alpha blockers - such as tamsulosin (Flomax) and alfuzosin (Uroxatral), which are used to treat symptoms of an enlarged prostate, lower blood pressure in some men. Make sure to take them at least four hours apart from an ED drug.

Key differences between ED medications

It's important to realize that ED drugs don't increase sexual desire, and you have to be ready and sexually stimulated for them to work. The drugs won't work well if you are mentally or emotionally not ready for sex. You can't just take a pill, pay some bills or wash the dishes, and then go to the bedroom and think you'll be ready to go. When your mind is not there, you are not going to want sex, and no ED drug can fix that problem. Before trying an ED drug, it's best to step back and analyze your sex life and when your ED occurs.

ED drugs are not safe for all men.

Does it happen all the time or just in certain situations? Is it with only one partner or different ones? Does it ever happen when you masturbate? Are the problems associated with stress or alcohol? Asking yourself these types of questions can help identify if your ED may be more psychological than physical. Continue to take sildenafil even if you feel well.

Factor	Impact on Tablets	Advice
Smoking	Reduced blood flow	Quit smoking for better results
Alcohol Consumption	Can diminish effectiveness	Limit alcohol intake
Obesity	Impaired blood circulation	Maintain healthy weight
Stress	Affects libido and response	Practice stress-reducing techniques
Exercise	Improves cardiovascular health	Regular physical activity

Do not stop taking sildenafil without talking to your doctor.

How effective are Viagra, Cialis, vardenafil, and Stendra?

Sildenafil (Liqrev, Revatio) is used to improve the ability to exercise in adults (Liqrev, Revatio) and children 1 year of age and older (Revatio) with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

How are oral ED drugs similar?

Yet many men still approach ED drugs the wrong way. Men feel their sex life is not good and see an ED drug as an easy, quick-fix solution. But more times than not, there are underlying issues at play that a pill can't help. While men might have other sexual issues, such as low libido, premature ejaculation, and the inability to achieve orgasm, ED pertains explicitly to not being able to get or maintain an erection. ED drugs address only that issue, by improving blood flow into the penis and keeping the blood in place to maintain an erection.

Some side effects can be serious. If you experience any of the following symptoms, call your doctor immediately:

There are four ED drugs currently available: sildenafil (Viagra), avanafil (Stendra), tadalafil (Cialis), and vardenafil (Levitra). At least one ED drug works in about 70% of men, but results vary among individuals. Men who have nerves or arteries damaged by prostate surgery, diabetes, or cardiovascular disease often do not respond as strongly to ED drugs. Finding out is often a trial-and-error approach. Many doctors first prescribe Viagra because it has been around the longest and has a high success rate.

The best place to get medications for ED

If one drug doesn't work after a predetermined period, your doctor may increase the dosage or prescribe one of the others. Sometimes, you have to try all of them before knowing whether ED drugs work for you. An ED drug kicks in within 15 minutes to an hour after you take it and can last anywhere from four to five hours up to 24 hours or longer depending on the drug. (See "ED drugs: How soon and how long?") It's best not to take the pill with food or soon after a meal, which can block absorption. The most common side effects are headaches, upset stomach, nasal congestion, muscle pain, and facial flushing.
