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.

A new study finds that some men who take Viagra have a higher chance of getting heart problems than those who don’t take the drug. A few of the findings suggest that ED medications like sildenafil, Cialis, or Viagra, which are used to treat erectile dysfunction, are linked to a more serious health condition called, or ED. Viagra, the drug from Eli Lilly and Co.’s patent for Viagra, is also linked to a higher risk of developing the condition.
The study found that men who take Viagra, even those who don’t take sildenafil, were more likely to develop ED than those who don’t take the drug. These findings are in contrast to findings from the Food and Drug Administration, which found that men who take Viagra, such as those taking Cialis, who do not have ED, were more likely to develop ED.
Researchers noted in their analysis that Viagra is only one of several treatment options for ED that can help patients. The other two are PDE5 inhibitors (which work by blocking the action of the enzyme PDE5) and nitric oxide donors such as, or nitric oxide donors, which work by relaxing muscles and arteries.
Viagra and PDE5 inhibitors, including sildenafil and Cialis, can help people who have erectile dysfunction by lowering their blood pressure. These medications have long been used to treat erectile dysfunction, but they are not typically approved by the FDA for treating ED. However, some people who use these medications to treat erectile dysfunction also have serious side effects, including heart problems, strokes, and low blood pressure.
Viagra and PDE5 inhibitors, which work by blocking the action of the enzyme PDE5, are not typically prescribed for ED. However, some men who take these medications to treat erectile dysfunction have found that their ED symptoms improve within the first four weeks of treatment.
The study found that men who take Viagra, which are known for their lower blood pressure, were more likely to develop ED than those who don’t take the drug. This is the first study to look at how well these medications work in the body, and the study also found that Viagra users who are taking their erectile dysfunction medications have higher rates of ED.
This study also found that erectile dysfunction is a common side effect of Viagra, which is why some men who take the drugs to treat erectile dysfunction may find that ED medications are a better choice for them. However, some doctors who take these medications to treat erectile dysfunction may not be able to prescribe the drugs to their patients.
Researchers are still waiting for the FDA approval of the new drugs, but they believe that the findings should be considered by all men who use these medications to treat erectile dysfunction.
“If you’ve been taking Viagra for a while and you’re worried about ED, don’t wait for a new drug application. There are other treatments available, like sildenafil or Cialis. If you are suffering from ED, you shouldn’t take Viagra,” Dr. Thomas C. Hittner, M. D., said in an email. “If you have erectile dysfunction and your partner is trying to get or keep an erection, you should consult a doctor first.”
