What Side Effects Can You Expect From These Medications?

Patients need sexual stimulation and foreplay to release NO initiate an erection in order for these medications to be effective. This class of medication is a safe and effective oral treatment for men with erectile dysfunction of physical, psychological or mixed cause. However, it is important that patients should be aware of the low probability (less than 50%) that intercourse will be possible after the first dose – particularly in severe or advanced cases and especially when using Viagra or Levitra. The majority of men who stop Viagra because of apparent lack of effect will in fact respond and achieve intercourse if they continue to try again, progress from 50 mg to 100 mg, or take the pill without food on an empty stomach (3 hours after eating). Taking Viagra or Levitra on a full stomach will not only reduce their peak concentration in the body by 30 to 50% but in addition will delay their peak concentration by one hour.

In other words one may have to wait after intake before initiating sexual activity. Cialis peak concentration and time before reaching maximum absorption is not affected by a full stomach. Because of this it remains my drug of choice for the treatment of ED and I always prescribe it first. In addition many of my patients experience fewer side effects with Cialis then with the other two. Finally Cialis has a long period of activity and patients are successful at intercourse up to 36 hours after taking this pill. The side effects are generally mild and do not last very long. The most common side effects are headache, flushing, stuffy or runny nose. In rare cases Priapism and vision changes have been observed. Levitra is contraindicated in patients who take any form of medication known as nitrates or recreational drugs called “poppers” like amyl nitra or butyl nitrate. If you are taking any alpha blockers, Levitra is not the right medication for you.

In addition he takes testosterone and sildenafil as needed. This is a classic example of why people with ED need complete care: a psychological exam, history and physical exam, and diagnostic studies with long term follow-up care. Patients with ED should not just be prescribed sildenafil (Viagra) and then be lost to follow-up. Cialis, Levitra (Vardenafil) and Viagra™ (Sildenafil) work by selectively inhibiting an enzyme in the penis called Phosphodiesterase V (PDE V), a chemical that takes away the erection.

Back pain and muscle aches occur rarely with Cialis. HIV medications (protease inhibitors) have been shown to raise their blood levels. Certain patient groups are more susceptible to a decrease of their blood pressure, including those with aortic stenosis, hypertrophic obstructive cardiomyopathy, and multiple system atrophy. Finally, all PDE 5 inhibitors remain contraindicated in patients taking nitrates. If initially not successful, patients should try Viagra™ at 100mg on 3 different occasions before concluding that the medication is ineffective.

Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles. Pharmacokinetics, half-life, is how long the medication stay s in the blood. This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known. Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication.

How should I store vardenafil?

The drawback is if you need nitrates after using tadalafil (Cialis), this medication lasts a long time in your blood stream and may place you at a higher risk. Younger people might do well treated with tadalafil, (Cialis) while older people with other health issues might be better off using sildenafil (Viagra) or vardenafil (Levitra) but more data are needed. The side effects of vardenafil (Levitra) are potentially less than sildenafil (Viagra), but more data are needed. In a recent study on men with erectile dysfunction and diabetes, vardenafil (Levitra) improved their erectile dysfunction. Tadalafil (Cialis) is as effective as sildenafil (Viagra), and vardenafil (Levitra) with similar side effects except for back pain that occurs occasionally with tadalafil, probably because of the long half-life. For example, spinal cord injured males have better results than patients suffering from cardiovascular disease (e.g. hypertension, high serum fat levels), and patients who have undergone treatment for prostate cancer (e.g. removal of the prostate or radiation therapy) seem to benefit the least.
