Cialis – Usage,Dosage And Side Effects

Overview – Cialis

Cialis is a prescription medication used to treat erectile dysfunction (or ED) in men. Tadalafil is the active ingredient in Cialis. ED refers to the inability to attain or maintain a viable erection needed for sexual intercourse. This can be due to several factors including poor rate of blood flow to the penis, excessive alcohol intake, fatigue, chronic illness and taking some medications. Tadalafil is also prescribed for treating pulmonary hypertension and enlargement of the prostate.

Tadalafil, the active ingredient in Cialis, is a PDE5 (phosphodiesterase inhibitor). It works by blocking the breakdown of phosphodiesterase, an enzyme which interferes with substances that induce an erection. This enables a man to easily attain and sustain an erection. Cialis also makes the penis blood vessels to dilate, which allows more inflow of blood into the penis. The drug boosts the workings of chemical messengers which help to make an erection.

Dosage

The medication is provided in two types of strengths-10 milligrams and 20 milligrams. However there are 2 and 5 milligrams tablets which are known as Cialis once a day. The 10 and 20 milligrams are taken when needed, typically at least half an hour prior to sexual intercourse. The effect of a single dose can last up to 36 hours. The once a day tablet is meant to be taken daily and preferably at the same time in order for it to have continuous effect. Alcohol should be avoided when using the medication as it may reduce its effectiveness and degrade sexual performance. Grapefruit juice can interact with the medication and this is potentially harmful to the user. Women and people under 18 years may also not take Cialis.

Side Effects, contraindications and drug interactions

Common side effects of taking Cialis include back pain, stomach discomfort or pain, burping, indigestion, runny or stuffy nose, acid reflux, muscle aches. Serious side effects include impairment of vision, shortness of breath, sudden loss of hearing, lightheadedness and chest pain. Patients are advised to consult a doctor if they get an erection lasting over four hours. A prolonged erection (also called a priapism) can cause penis damage.

Patients should avoid Cialis if they are taking nitrates to treat chest pain. Taking poppers (amyl nitrate) and mixing with Cialis could result in a sudden and fatal drop in blood pressure. There are drugs that might interact with Cialis. These include those taken for treating angina, prostate conditions, high blood pressure, HIV, fungal infections, stomach acid, pulmonary hypertension and bacterial infections. It is recommended that patients talk to their doctors if they are using such medications before taking Cialis. The doctors should also advise the patient if his heart is healthy enough to engage in sex.

Missed dose

Generally, Cialis is taken as needed-that is, before sexual intercourse. However, if a patient is taking Cialis every day and they forget one dose, they should take it as soon as they remember. Taking a dose to make up for a missed dose is not recommended.

Storage

Cialis tablets should be stored in the original packet until it is time to use them. They should be stored in temperatures below 25 degrees Celsius .The tablets should also be kept away from children.
