About 25 to 50% of men who undergo brachytherapy will experience erectile dysfunction vs. nearly 50% of men who have standard external beam radiation. After two to three years, few men will see much of an improvement and occasionally these numbers worsen over time. Men who undergo procedures not designed to minimize side effects and/or those whose treatments are administered by physicians who are not proficient in the procedures will fare worse. Men with other diseases or disorders that impair their ability to maintain an erection (diabetes, vascular problems, etc.) will have a more difficult time returning to pre-treatment function. Oral medications relax the muscles in the penis, allowing blood to rapidly flow in. On average, the drugs take about an hour to begin working, and the erection-helping effects can last from 8 to 36 hours. About 75% of men who undergo nerve-sparing prostatectomy or more precise forms of radiation therapy have reported successfully achieving erections after using these drugs. However, they are not for everyone, including men who take medications for angina or other heart problems and men who take alpha-blockers. Men who do not recovery erectile function after treatment can try injectable medication that pharmacologically induced an erection. The most common drug used for this is Prostaglandin. The vacuum constriction device creates an erection mechanically by forcing blood into the penis using a vacuum seal. A rubber ring rolled onto the base of the penis prevents blood from escaping once the seal is broken. A three-pieced surgically inserted penile implant includes a narrow flexible plastic tube inserted along the length of the penis, a ... More

A single drink is five ounces of wine, 12 ounces of beer, or one shot (1.5 ounces) of hard liquor, and a person should not consume more than two drinks in a single day or time period in order to be drinking moderately. A person who struggles with alcohol abuse or alcoholism should probably not drink while taking Viagra, though this may be easier said than done. Addiction, a mental reliance on a substance such as alcohol, and physical dependence can make it hard for a person to stop drinking once they start. Addiction aligns a person’s thinking with alcohol consumption, so a person is unable to stop drinking once they start, even if they know they shouldn’t continue. Physical dependence causes a person to experience uncomfortable, at times life-threatening, withdrawal symptoms so they continue drinking. People thinking of taking Viagra while drinking should consult their doctor first, and anyone with a substance use issue should seek treatment options before trying new medications. People in need of treatment for alcohol abuse or dependence should consider inpatient treatment. Alcohol dependence is all-consuming, and withdrawal from alcohol is extremely difficult and even dangerous to manage on one’s own. Medically supervised detoxification programs within inpatient rehab centers allow a person to seek the care they need to detox safely, so they can begin formal addiction treatment. Medications within inpatient rehab programs are monitored and administered by staff to ensure a person does not misuse their medications. Inpatient treatment programs provide individuals with all the tools and treatments necessary to overcome addiction and dependence, such as counseling, ... More

Both therapeutic and supratherapeutic doses of vardenafil produce an increase in QTc interval. At high doses, loperamide has been associated with serious cardiac toxicities, including syncope, ventricular tachycardia, QT prolongation, torsade de pointes (TdP), and cardiac arrest. Loperamide; Simethicone: (Moderate) Consider the potential for additive QT effects if vardenafil is administered with loperamide. Both therapeutic and supratherapeutic doses of vardenafil produce an increase in QTc interval. At high doses, loperamide has been associated with serious cardiac toxicities, including syncope, ventricular tachycardia, QT prolongation, torsade de pointes (TdP), and cardiac arrest. Lopinavir; Ritonavir: (Major) Coadministration of ritonavir with vardenafil results in a 20% decrease in ritonavir AUC and a 49-fold increase in vardenafil AUC. Substantially increased vardenafil plasma concentrations may result in increased associated adverse events including hypotension, syncope, visual changes, and prolonged erection. If coadministered, use vardenafil at reduced doses of no more than 2.5 mg every 72 hours with increased monitoring for adverse reactions. Vardenafil orally disintegrating tablets provide increased exposure as compared to the regular tablets; therefore, use of the orally disintegrating tablets with ritonavir is not recommended. In addition, both ritonavir and vardenafil are associated with QT prolongation; concomitant use increases the risk of QT prolongation. (Major) Particular caution should be used when prescribing phosphodiesterase type 5 (PDE5) inhibitors to patients receiving lopinavir; ritonavir (Kaletra).

That why it’s important to talk it over with your doctor. What Can Cause Erectile Dysfunction (ED) ED is not a natural part of aging. In most cases, it is caused by a physical problem, which can include: Cardiovascular disease, such as clogged blood vessels or hardening of the arteries. The main artery in the penis is only 1 millimeter in size. If blood cannot flow freely through this vessel, then ED can occur. Cardiovascular risks like high cholesterol, obesity, and high blood pressure Diabetes Nervous system diseases like multiple sclerosis and Parkinson’s Low testosterone. ED can also be caused by lifestyle choices that put your health at risk, such as drinking too much alcohol, use of narcotics, and smoking – or by behavioral conditions like anxiety and stress. Sometimes medications can cause ED, but this not common. If you are taking a new medication and begin having erection problems, talk to your doctor; your medication or the dose you take may need to be changed. Making some lifestyle changes on your own can help you get erectile dysfunction under control. Avoid smoking and the use of alcohol and narcotics Get regular exercise to help reduce stress, lose weight, and increase blood flow Talk the problem over with your partner – often it helps to get it out into the open and see what the two of you can do to relieve stress Learn relaxation techniques through the practice of yoga or mediation to help reduce stress. Biofeedback therapy, a technique that trains you to control certain physiological processes by giving you immediate feedback, can also be very effective in reducing stress. Erectile dysfunction is a very treatable condition, and most men see improvements ... More

Penile implants are the most invasive treatment but provide durable results and the highest satisfaction rates of all of treatments. Given the prevalence of ED, there is significant incentive to find more effective and less invasive treatment options. Here we review new and emerging treatment options for this common condition. We also review the use of nutraceuticals, which are not new but have seen explosive growth in recent years (see, “Nutraceuticals for ED at a glance.") New oral agents and pathways. PDE-5 inhibitors remain the cornerstone of oral therapies. Researchers have explored alternative pathways for novel therapeutics (table), although success has been limited. Currently, no novel oral medications are in clinical development. Prior targets have focused on central pathways (dopaminergic and melanocortin) and peripheral pathways (guanylyl cyclase and Rho-A/Rho kinase), but novel oral therapies directed at these pathways have shown limited efficacy and tolerability. An overview of the cellular pathways is shown in the figure. Initially, the use of dopamine agonists for Parkinson’s disease was associated with increased libido. Apomorphine is a dopamine D1 and D2 receptor agonist that was approved for ED in Europe in 2001. In a phase III double-blind, parallel-arm, crossover study of nearly 900 men with ED, more than 50% of those using apomorphine were able to obtain an erection sufficient for intercourse compared to 33% of men using placebo (BJU Int 2002; 89:409-15). However, the FDA did not approve the drug in the United States because of concerns about hypotension. Similar medications (ABT-724 and ABT-670) targeted to the D4 receptor have also been studied, ...

This means that a lot is known about its effects and side effects. It works within an hour of taking a tablet, and is best taken on an empty stomach. The effects of Viagra will last for four to six hours. Viagra was developed and originally marketed by the pharmaceutical company Pfizer, and until 2013 Pfizer was the only company allowed to sell it. When Pfizer’s patent on Viagra expired, the market was open for other companies to produce the medicine, albeit under its generic name Sildenafil, rather than the brand name Viagra. Sildenafil contains exactly the same active ingredient as Viagra (sildenafil citrate), and works in the same way. However, because it is the generic version of the medicine, rather than the brand, Sildenafil is considerably cheaper. Levitra will last for a similar amount of time as Viagra (four to six hours). The main difference to Viagra is that Levitra tends to be less affected by food or alcohol so can be taken with meals. There is also some evidence that Levitra is more effective in diabetics than other erectile dysfunction medicines. The effects of Cialis (tadalafil) last much longer than those for Viagra or Levitra (up to 36 hours) so many men prefer it as involves less planning. The downside is that if you do experience side effects these can last for longer too. Like Levitra, Cialis is not affected much by food, so can be taken after a meal. Different erectile dysfunction medicines suit different people, but it is difficult to tell which one will be best for you until you have tried them all. While a particular erectile dysfunction medicine may not work for you first time round, we recommend taking it at least eight times before giving up ... More

Activities that constrict blood flow to the penis may increase the risk for erection problems. For example, frequent long-distance bicycle riding on a hard, narrow saddle may increase risk. But the possible link between bike riding and erection problems has not been proved. A vasectomy usually doesn't cause erection problems. But pain after the operation may affect sexual performance for a time. And if a man wasn't comfortable with his decision to have a vasectomy, or if he's having second thoughts, it could affect him psychologically. Call your doctor now or seek medical care right away if: You have an erection that lasts longer than 3 hours. You have taken sildenafil (for example, Viagra) or vardenafil (for example, Levitra) in the past 24 hours or tadalafil (for example, Cialis) in the past 48 hours, and you have chest pain. Make sure all the doctors you see know that you took one of these medicines. You have erection problems that occur along with pain or difficulty with urination, fever, or pain in the lower belly. Call a doctor if erection problems occur: With any type of injury to the back, legs, buttocks, groin, penis, or testicles. With other symptoms such as loss of hair, enlargement of the breasts, or backache. If your erection problem happens just now and then, there is no reason to call your doctor. If it happens often and upsets you or your partner, it is okay to call your doctor. If an erection problem doesn't bother you or your partner, you may choose not to call your doctor. A single episode of an erection problem is often a temporary problem that is easy to reverse. Try to forget about it, and expect a more successful experience the next time. If you ... More

Semirigid malleable prostheses are the simplest and easiest to implant, but they can be difficult to conceal because the penis is always erect. Inflatable prostheses typically consist of two tubes that replace the corpora cavernosa, plus a pump in the scrotum and an intra-abdominal reservoir ( eFigure A ) . Mechanical failure goodrx coupon sildenafil or infection may require removal of the prosthesis. Risks include scarring, penile shortening, and recurrent infections. Prostheses coated with antibiotics have been used to reduce the risk of infection.64. Abstract Diagnosis Causes and Related Conditions History and Physical Examination Laboratory Evaluation Treatment Managing Psychogenic ED References. Many men have ED that is predominantly or exclusively caused by psychological or interpersonal factors.65 Psychogenic ED occurs at all ages but is most common in men younger than 40 years. A thorough history can elicit potential causes such as performance anxiety and relationship conflicts, which distract attention and impair sexual arousal. Problems such as premature ejaculation, genital pain, or dyspareunia can lead to psychogenic ED, as can cultural or religious taboos or a history of sexual abuse. Although men and their partners may resist a psychological explanation for ED, counseling can be effective.60. ED of mixed organic and psychogenic origin is common. Psychogenic causes are more likely when the patient has normal erections with masturbation or when nocturnal penile tumescence is normal. Devices are available to measure the number, duration, and rigidity of erections during sleep. However, normal nocturnal erections do not always correlate with sexually relevant ... More
