Cialis is the brand name of the generic Tadalafil and is now produced and marketed by Eli Lilly and company. It is the third male impotency drug launched in 2003 after Sildenafil (Viagra) and Vardenafil (Levitra). It is unique in its ability to maintain its affect for about 36 hours for which it is given the nickname ?weekend pills?. Drug administration has become popular with the advent of Viagra in 1998, since other therapies for treating erectile dysfunction were burdensome and even risky at times.

As with all other kinds of medications, Cialis too has some drug interactions and some side effects when administered. Typical drug interactions include Tadalafil being a PDE5 inhibitor causes hypotension and therefore organic nitrates must not be taken for 48 hours after the latest dose of tadalafil. Usage of organic nitrate in that period may even be a threat to life. As patients cannot take any kind of nitrates within 48 hours, they need to take medical assistance if any complication like anginal chest pain occurs.

Cialis has some side effects like severe headache, stomach upset, muscle aches, back pain, flushing, nasal congestion and even runny nose. These side effects are generally mild and go away after a few hours. Muscle aches and back pain start after 12 hours and go after 48 hours themselves. Cialis may rarely lead to Priapism (erection lasting more than 6 hours) and proper medical help has to be taken in such case. Impairment of vision is also reported by some other patients. It is not sure if they are related to Cialis or not, but if any haziness or hue occurs in the eye, patients are advised to stop taking Cialis and contact the doctor.

Loss or decrease in hearing noises, some kind of ringing in the ears, dizziness can occur. Medications for diabetes mellitus, hypertension, coronary heart disease, hyperlipidemia, alcohol and drug abuse, smoking may interfere with Cialis and the combinations sometimes can be deadly also. From October 2007, FDA wanted all the companies producing PDE5 inhibitors to label all the potential risks involved with taking those pills due to the post marketing reports of deafness linked with usage of PDE5 inhibitors.

Sickle cell anemia, Leukemia and multiple myeloma are some of the blood cell diseases that are at high risk of developing Priapism. Priapism untreated may cause permanent injury to the penis and even loss of potency. Tadalafil shouldn't be used with alpha blockers like terazosin (Hytrin), tamsulosin (Flomax), alfuzosin (Uroxatrol), doxazosin (Cardura), and prazosin (Minipress) because the combo of tadalafil and an alpha blocker lowers the blood pressure substantially causing dizziness and fainting. Tamsulosin can be safely used with tadalafil but only for healthy men with a lower dosage of 0.4 mg of flomax daily.

Tadalafil is not prescribed for men with conditions like Low blood pressure, Unstable angina, Uncontrolled high blood pressure, Recent history of a heart attack, any kind of liver disease, severe damage or disease of heart's valves, retinitis pigmentosa. So men with the above conditions shouldn't go for tadalafil before all those conditions tested, evaluated, diagnosed and stabilized first. Doctors need to determine if the patients with heart diseases have enough heart reserves left to carry out and sustain the sexual tension during intercourse and may recommend treadmill testing.

Tadalafil takes almost more than 2 days to clear out (metabolize) from the body. Metabolism of Cialis can be slowed down by kidney disease, liver disease, and simultaneous usage of anti fungal medicines like ketoconazole, erythromycin. Slowed breakdown makes it possible for tadalafil to stay longer and thereby increasing the risk of side effects. Thus it can be said that though cialis has some side effects, it is one of the best medications available today. Patients can buy Cialis online through many online shops and bids and can get their pills and also their manliness back at a discounted rate.
