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.

SINGAPORE - A drug maker has warned that its prescription drug Viagra may lead to a rise in the cost of erectile dysfunction treatment, but that it may be a risk to health. The drugmaker, Pfizer, said that its latest guidance on its prescription-only treatment for impotence and the high-dose sildenafil, the generic name for Viagra, could be a reason for the rise in prescriptions.
The drugmaker warned that it was taking measures to prevent patients from taking Viagra for erectile dysfunction in the past two years.
The drugmaker said that it had received reports of a rise in prescriptions for Viagra in the past few years, which was more than two times the maximum dose.
The warning, which was published in the British Medical Journal, came after it was discovered that the erectile dysfunction drug, called sildenafil, contained an impotence drug called Viagra.
The drug, which is sold as Levitra and Cialis, is a generic version of Viagra, and Pfizer said that the drug is sold under the brand name Cialis, but has been withdrawn from the market.
Pfizer said that they were disappointed with the guidance but would not comment on the findings of its latest study.
The company said that it would be removing a study of Viagra from the market immediately.
Pfizer, which has been trying to bring Viagra into the market since it was launched in 1998, said it would continue to work with the pharmaceutical industry to address the problem.
It added that it had conducted a study in 2016 and will continue to monitor the situation to ensure it is effective and safe.
In a statement, Pfizer said that its research had found that the erectile dysfunction drug was linked to an increase in the risk of a number of serious side effects, including priapism and other heart problems. It also reported that patients taking the drug had an increased risk of serious allergic reactions, as well as an increased risk of stroke, heart attack, and liver damage.
The company said that the increased risk was not the result of a higher dose of the drug, but was related to the drug's chemical structure.
The company said that the data was reassuring, as there was no increase in the amount of Viagra in the last two years.
Pfizer, which is listed on the British Pharmacopoeia as one of the world's largest pharmaceutical companies, said that its products are the most widely prescribed drugs in the world, and that more than 1 million prescriptions were written for them.The company said that its products were well-suited to the health of the elderly and children.
It said that the results of the study showed that the drug had a risk of heart problems, but not priapism, which is a serious medical problem. The drug is not used in the treatment of erectile dysfunction. Viagra was the drug's first prescription-only medication after its launch in 1998.
Sildenafil is the generic version of Viagra, which is used to treat erectile dysfunction.
