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:
When taking Cialis, combining tadalafil with nitrates, which are commonly used to treat high blood pressure, can lead to potentially dangerous drops in blood pressure that can be fatal. This can include dizziness, fainting, or heart attack or stroke (dizziness). If you need help managing these symptoms, consider using a lower dose or supplemental hypertension treatment such as a combination of Cialis and nitrates.
Cialis works by inhibiting the enzyme PDE5, which is responsible for breaking down testosterone in the body. By blocking this enzyme, Cialis can increase blood pressure levels, while reducing blood pressure by lessening hypertension. This method of blood pressure treatment is usually faster than taking alpha-blockers or PDE5 inhibitors.

Viagra, the generic form of Viagra, was developed to help men with erectile dysfunction (ED) manage their sexual performance by relaxing blood vessels and allowing more blood to flow to the penis.
However, because the medication has a ‘potent’ effect on the brain, the FDA has banned it from being sold in the US, and Pfizer has not issued a warning about its use in the UK.
In an announcement in January, the company said that it was “working closely with the FDA to determine if Viagra could be prescribed for the treatment of erectile dysfunction, particularly for men who have not responded to other ED treatments”.
Pfizer, the makers of Viagra, told the Guardian, but had not responded to a request for comment.
The company said its decision to not sell the drug for erectile dysfunction was “due to a lack of urgency and awareness among users, and we remain confident that the decision will be taken in the best interests of patients”.
Viagra and other erectile dysfunction drugs are available over the counter in the UK, but only under a doctor’s prescription.
The UK government will not give the drug to patients who cannot take a pill in the UK.
The UK’s health regulator also said there was no evidence that the drug affected health, but said it was unlikely it affected “any of the most common symptoms of erectile dysfunction, including difficulty in achieving or maintaining an erection”.
Pfizer said the decision to sell Viagra was taken after its patent for Viagra expired in 2006 and other similar drugs had been licensed for sale over the internet.
The UK government said it would look at the drug’s safety in patients who have not responded to other treatments for ED.
Viagra is an effective treatment for about 80% of men with ED, and is usually prescribed to men who are already on certain medications, including some drugs for conditions such as blood pressure and diabetes.
The company said its decision to sell Viagra was due to the “possible impact of a possible interaction” with another medication, such as nitrates.
“The potential interaction between Viagra and nitrates could lead to serious cardiovascular events, and this could increase the risk of heart attack and stroke, so it’s important that patients taking Viagra do not take nitrates while on Viagra,” it said.
Pfizer also said it was working closely with the UK’s health regulator on a review of Viagra, and it was “in the best interest” of the drug to be sold in the UK.
Viagra is sold as a generic version of the drug called sildenafil, which was developed to treat ED and is available for sale in the UK for the treatment of both erectile dysfunction and pulmonary hypertension.
Viagra was approved in the US in the 1990s, and is now available to buy as a generic version, although it is not expected to be sold by the time of the UK’s approval.
The FDA is also working with Pfizer to determine if Viagra is safe for patients who have not responded to other ED treatments and to make an assessment of the benefits and risks of the drug.
Pfizer said that Viagra had been sold as a generic version of the drug under the brand name Revatio. The company was working closely with the FDA on a review of Viagra’s safety and efficacy in people with ED, as well as those who have other conditions, such as high blood pressure.
It said: “Revatio is not intended for use by women and is not approved by the FDA for use in women.”
In a statement, Pfizer said: “Pfizer is committed to patient safety and has worked closely with the FDA to ensure that Viagra is available for the treatment of erectile dysfunction and pulmonary hypertension.”
Pfizer said it was working closely with the FDA to determine whether Viagra could be sold in the UK.The company has not responded to requests for comment.
Viagra is available in the UK without prescription in some countries, but is only available under a doctor’s prescription.
Pfizer is not releasing any information about the company’s decision to sell Viagra in the US, but said it had no plans to update its website or make any changes to its product information.
