Drugs that administered to patients by doctors to treat a specific disease or health condition are prescription drugs. It’s true that if prescription drugs are used correctly and under a doctor’s care they are not damaging. But if you make use of prescription drugs not including a doctor’s support (non-medical use) you can suffer from severe health problems for the reason it’s always dangerous. Before prescribing the drug in question medical doctors should discuss with their patient the contraindication of any prescription drugs with other drugs.

It is always best to seek advice from your doctor ahead of you start using any prescription medications, counting those for erectile dysfunction. And as a matter of fact you always should think very well prior to paying money for prescription drugs if you see any shop over the internet claiming to sell them. It’s absolutely true that any lawful medical doctor would never recommend you a drug if he even doesn’t estimate your symptoms.

The CIALIS difference
Cialis is a well-known prescription tablet. It’s used to treat Erectile Dysfunction in men. It was found that the ‘36-hour Cialis’ works in some men in 30 minutes. All of this makes for some remarkable literature; however what’s more main is to read the fine print. And alas for Cialis, it’s all in the fine print...

• You should notice that Cialis is not to be received in combination with medicines like Nitrates. Nitrates are typically prescribed for chest pains and angina. Similar to most other prescription medicines, Cialis is as well infamous for its drug interactions.
  
• Side effects: Very often men can suffer from headache and upset stomach. An erection that lasts more than four hours (Priapism), is a probable side effect, as is a sudden decrease or loss of vision (take care of one dysfunction and get another one or more! Not incredibly attractive pay money for one, get one free offer). In addition backache and muscle ache have also been reported, occasionally with delayed onset.
  
• Cialis has not been studied for multiple sexual attempts per dose (If a playful moment turns into the right moment, you can be ready, but just ONCE).

Cialis® must not be taken under the following circumstances:
Nitrates are so called medicines which are commonly used to treat angina, a symptom of heart disease, which causes pain in the chest, jaw, or arm. Nitrates consist of nitroglycerin that is found in tablets, sprays, ointments, pastes, or patches.

• Medicines called alpha blockers. These take in Hytrin® (terazosin HCl), Flomax® (tamsulosin HCl), Cardura® (doxazosin mesylate), Minipress® (prazosin HCl) or Uroxatral® (alfuzosin HCl). Alpha blockers are occasionally prescribed for prostate problems or high blood pressure. If Cialis® is got with certain alpha blockers, the blood pressure could unexpectedly drop, making the patient dizzy or faint.

Possible side effects with Cialis®

Headache, indigestion, back pain, muscle aches, flushing, and stuffy/ runny nose are the most frequent side effects with Cialis®. Patients who get back and muscle aches as a rule get them about 12 to 24 hours following taking Cialis®.

Cialis® may cause Priapism (an erection that lasts longer than natural). You should treat Priapism as soon as you can or else lasting harm can take place to the penis as well as the absolute inability to have erections.

You as well may suffer from vision changes, for example seeing a blue tinge to objects or having complexity telling the dissimilarity between the colors blue and green while taking Cialis®.

At times men taking Cialis® and other oral erectile dysfunction medicines (PDE5) complain of a sudden decrease or loss of vision in one or both eyes.

You should Say "No" to Viagra®

Men, for whom sexual activity is not advisable for the reason of their weak cardiovascular conditions, mustn’t use such prescription treatments as Viagra® for erectile dysfunction. There is potential for cardiac hazard in such patients with preexisting cardiovascular disease. Viagra® has total vasodilator properties that resulted in brief reduce in supine blood pressure in healthy volunteers throughout tests. Concomitant use of PDE5 inhibitors (like Viagra®) co-administered with alpha-blockers, may extensively lower blood pressure which lead to symptomatic hypotension (e.g. dizziness, lightheadedness, fainting) in a number of patients.

In the following groups of patients with the following conditions there is no controlled clinical statistics on the security or effectiveness of Viagra®:

• Incidence of a heart attack, stroke/ life-threatening arrhythmia within the last 6 months
• Resting hypotension or hypertension
• Cardiac failure or coronary artery disease causing unstable angina
• Retinitis pigmentosa

Viagra® should be prescribed with watchfulness to patients with the above conditions.

The use of such mixtures is not recommended for the reason that the safety and efficacy of combinations of Viagra® with other treatments for erectile dysfunction have not been studied.

As well in patients with bleeding disorders and patients with active peptic ulceration the safety of Viagra® is unidentified.

Possible side effects with Viagra®

It has been reported prolonged erections for greater than 4 hours and Priapism (painful erections greater than 6 hours in length) since market approval of Viagra®. It was fond that this could cause tremendous damage to the penis and permanent loss of potency. You should seek immediate medical assistance if an erection persists longer than 4 hours.

You should use Viagra® with caution if you have anatomical deformation of the penis (such as angulation, cavernosal fibrosis or Peyronie’s disease), or if you have conditions which may predispose to Priapism (such as sickle cell anemia, multiple myeloma, or leukemia).

At times men report non-arteritic anterior ischemic optic neuropathy (NAION), a cause of reduced vision which may include permanent loss of vision, post-marketing in temporal connection with the use of all PDE5 inhibitors.

Patients should take caution if Viagra® is prescribed to patients using Ritonavir (protease inhibitor), for the reason that Ritonavir to a large extent increases serum concentrations of sildenafil. Visual disturbances happen more generally at higher levels of sildenafil exposure. It was found that decreased blood pressure, syncope, and prolonged erection take place in some healthy volunteers exposed to high doses of sildenafil (200-800 mg).
