Roughly 18 million men in the United States suffer from erectile dysfunction, also referred to as ED.And though it’s more common in older men, ED can happen at almost any age.

Certain factors can increase a man’s likelihood of developing the condition including high blood pressure, diabetes and high cholesterol.

The good news is, it’s treatable in most cases

Many men turn to medications such as cialis for help.

While turning to the internet to purchase the drug online can save money, it’s important to make sure you’re getting a safe product when you buy cheap Cialis online

How does Cialis work?

Cialis, generically known as the drug tadalafil, helps men who have trouble achieving erections.

Typically, to get an erection, blood flows into the penis and is temporarily trapped there causing the penis to expand.

When this process is interrupted, ED occurs.

Cialis works by increasing blood flow to the penis and Cialis is also said to improve overall satisfaction with the hardness of erections.

Though, you won’t get an erection by simply taking the medication, sexual stimulation is still required in order for Cialis to work.

After intercourse, the erection should go away as normal.

In rare cases they last longer. If an erection lasts more than four hours, immediate medical attention is required to help avoid permanent damage.

How often should Cialis be taken?

Cialis comes in four doses:

• 2.5 Mg

• 5 Mg

• 10 Mg

• 20 Mg

Most patients begin by taking to 10 mg dose before sexual activity.

The dose can be increased to 20 mg or lowered to 5 mg based on how it affects each individual.

Usually, the dose is taken just once per day.

Common Cialis side effects

• Headaches

• Indigestion

• Muscle aches

• Stuffy or runny nose

• Back pain (symptoms tend to arise 12 to 24 hours after taking CIalis and usually subside in two days)

Serious Cialis side effects

CIALIS can cause your blood pressure to drop suddenly if taken with certain other medicines..

You could get dizzy, faint, or have a heart attack or stroke. Never take CIALIS with any nitrate or guanylate cyclase stimulator medicines..

In rare instances, men taking prescription ED tablets, including CIALIS, reported a sudden decrease or loss of vision or hearing (sometimes with ringing in the ears and dizziness).

“It’s not possible to determine if these events are related directly to the ED tablets or to other factors,” according to Cialis’ website, which advises, “If you have a sudden decrease or loss of vision or hearing, stop taking any ED tablet, including CIALIS and call a healthcare provider right away.”

It’s also important to be cognizant of any allergic reactions you may have to Cialis. Symptoms can include rash, hives, swelling of the lips, tongue or throat, or difficulty breathing or swallowing.

Before taking CIALIS, the company advises you to tell your healthcare provider about all your medical problems, particularly if you have or ever had:

• heart problems such as chest pain (angina), heart failure, irregular heartbeats, or heart attack

• pulmonary hypertension

• heart problems such as chest pain (angina), heart failure, irregular heartbeats, or heart attack

• low blood pressure or high blood pressure that is not controlled

• stroke

• liver or kidney problems or require dialysis

• retinitis pigmentosa, a rare genetic (runs in families) eye disease

• severe vision loss, including a condition called NAION

• stomach ulcers or a bleeding problem

• a deformed penis shape or Peyronie’s disease

• an erection that lasted more than 4 hours

• blood cell problems such as sickle cell anemia, multiple myeloma, or leukemia

If you begin to have chest pain, dizziness or nausea during sex, Eli Lilly and Company recommends stopping intercourse and seeking medical attention.
