Cialis Professional Side Effects
Cialis Professional has been produced on an improved formula, excluding some of the drug's most adverse components. Therefore, this drug is less likely to cause nasty side effects and has proven to be more effective than many other ED drugs. This is a prescription medicine, and it is available as film-coated tablets, which vary according to tadalafil concentration. There are 2.5mg, 5mg, 10mg and 20mg tablets. Dosage should be adjusted by a qualified doctor. Tadalafil belongs to the group of so called PDE5 inhibitors. Their effect consists in blocking phosphodiestrase type 5 (PDE5) enzyme, which keeps the smooth muscle of the penis strained and thus regulates blood flow to the penile chambers.
Cialis Professional does not usually produce unpleasant side effects in healthy people, except minor decreases in blood pressure. At the same time, it has a much longer period of action (36-48 hours), and therefore should not be used in combination with some medicines, which can potentiate its hypotensive effect. People with underlying chronic health problems must not use Cialis without a doctor's supervision.
Most Cialis-related adverse reactions occur due to the drug's hypotensive effect, augmented by concomitant use of alpha-blockers, nitrates, other vasolidators, etc. Low blood pressure may cause blood flow to vital organs to deteriorate and therefore affect their functioning. On the other hand, high plasma concentrations of tadalafil may result in the inhibition of enzymes responsible for the functioning of the optic nerve and cause vision problems. Low blood pressure may contribute to the occlusion of retinal blood vessels, which also affects vision. The drug's prolonged action increases the risk of non-arteritic anterior ischemic optic neuropathy (NAION), which may lead to permanent loss of vision.
There have also been reports about hearing problems associated with the intake of tadalafil. The risk of vision and hearing problems increases if Cialis users have underlying heart disorders, diabetes, hypo- or hypertension, hepatic impairment, renal insufficiency, viral infections, etc. Because no research has been held on the drugs relation, if any, with hearing difficulties, and these are just statistical suggestions, there is no telling how likely these adverse reaction are to occur. People with poor cardiovascular status should avoid using Cialis, first, because low blood pressure increases the risk of arrhythmia, tachycardia, ischemia, infarction and heart insufficiency. It is not advisable to use Cialis Professional for people suffering aortic stenosis and atherosclerosis.
Other common side effects include back pain, dizziness, nausea, loss of appetite and fatigue. PDE5 inhibitors may cause prolonged or spontaneous erection. Long-lasting erections (more than 4 hours) can be dangerous to penile tissues and therefore require immediate medical assistance.
