There’s a good chance that some of us have noticed a slight dip in the number of prescriptions for Viagra and Cialis — and that could be a sign of an underlying problem, says, a physician at the University of Minnesota’s medical school.
According to the, researchers from the University of Minnesota have found that Viagra and Cialis, both of which work to treat erectile dysfunction, have been prescribed in some cases to treat erectile dysfunction in men. The most common side effects are headaches, dizziness, and back pain.
In fact, a small number of Viagra and Cialis prescriptions are associated with the symptoms of ED. According to the, a survey of men’s health professionals in the U. S. found that about 80% of men taking Viagra reported erectile dysfunction.
While some men have reported having ED, most don’t know they have the symptoms.
“They might have a low libido, some might not have a high libido, or they might have problems with orgasm,” says, a professor at the University of Minnesota who was not involved in the study. The results are not known, but they suggest that men with ED may be more likely to have ED than men without ED.
Viagra and Cialis, like other ED medications, work by relaxing the muscles in the penis and increasing blood flow to the area. They’re also effective for reducing the symptoms of ED.
Cialis, however, is not without its risks. While Viagra and Cialis aren’t common, men who take them may experience certain side effects. For instance, it can cause a sudden drop in blood pressure, so men may experience dizziness, fainting, or vision problems.
Other side effects of Viagra and Cialis include headache, flushing, nasal congestion, and stuffy nose. In some cases, men who take them may also experience muscle aches, such as muscle pain and swelling in the arms and legs.
“This is a very common side effect, but it’s not a very common one,” says, a professor at the University of Minnesota’s medical school. “In fact, it’s a relatively rare side effect.”
According to a, Viagra and Cialis can cause sexual dysfunction in some men, though they are not common. The most common side effects of Viagra and Cialis are erectile dysfunction and impotence.
Viagra and Cialis aren’t recommended for use in patients with certain medical conditions, such as those that affect the penis. They can cause an erection only in men who have taken the medication for a long time. Cialis is also not effective in men with low blood pressure.
Viagra and Cialis are also not recommended for use in patients who have a history of heart disease or a history of heart attack or stroke.
“There’s a lot of stigma about erectile dysfunction,” says, a professor at the University of Minnesota’s medical school. “You have to take Viagra and Cialis before you need them.”
Viagra and Cialis are approved by the FDA, which has a black box warning in the side effects section of the drug’s label. However, Cialis is approved for use in men only, and men who have erectile dysfunction should take Viagra and Cialis at least twice a day.
Viagra and Cialis have also been approved for use in men who have or have had heart disease. However, it’s not a good idea to take Viagra and Cialis with nitrates, or in patients with severe heart disease. Nitrates are an alpha-blocker medication used to treat chest pain. Doctors recommend combining nitrates with Viagra and Cialis if the risk of sudden cardiac death increases after taking the combination.
Some men taking Viagra and Cialis have experienced a drop in blood pressure, which can make them dizzy, fainting, or faint.
As with any drug product, there may be side effects. Generally, patients who experience side effects usually get them within 12 to 24 hours after taking Tadalafil. Side effects usually resolve on their own within 48 hours. Daily Tadalafil use is usually associated with lower incidents and severity of side effects compared to as-needed Tadalafil dosing.

Possible drug interactions
Some drugs/medications may interact with Tadalafil. You should not take Tadalafil if you are taking nitrates (such as nitroglycerin tablets or patches) because the combination of these with Tadalafil could significantly lower blood pressure and lead to fainting or even death. Additionally, do not take Tadalafil if you are taking Cisapride, other ED medications (e.g. Viagra), Adcirca, or Riociguat.
On your intake form, please be sure to provide AgelessRx with all medications, herbs, non-prescription drugs, or dietary supplements you use. Also be sure to report if you smoke, drink alcohol, or use illegal drugs, as some may interact with your medication.

Other important safety information
Patients who have a condition called “left ventricular outlet obstruction” from valvular problems or heart muscle enlargement may get side effects such as fainting or light-headedness. Because patients with recent heart attacks or stroke, heart pains (angina), heart failure, uncontrolled blood pressure or uncontrolled irregular heart beats, severe liver disease, and retinal eye problems have not been studied, Tadalafil (Cialis) is not recommended for these patients. There may be rare occurrences of priapism or painful, prolonged erections. This is a serious condition that requires immediate medical attention. Patients should seek prompt medical attention if their erection lasts longer than four hours.
After taking a single tablet, Tadalafil can remain in the body for up to two days. It can remain longer if patients have problems with their kidneys or liver, or they are taking certain other medications.

1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
