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:
If you are taking Cialis or other medications to treat erectile dysfunction, it is important for your doctor to understand the interactions with your meal. Your doctor may then recommend a lower dose for Cialis.
Cialis (tadalafil) can interact with certain foods and beverages, so you should avoid consuming grapefruit or grapefruit juice while taking Cialis. Foods that high in Tadalafil may increase the effectiveness of Cialis' medications. If you take an inhibitors medication, consulting your doctor about whether to restart Cialis is recommended.
Dosage and direction:
Nitrates (e.g., amyl nitrate, isosorbide dinitrate): A powerful blood pressure-lowering medication used to treat high blood pressure and angina. This may reduce the risk of vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION), leading to dizziness, fainting, or even stroke.
Cialis has been shown to cause some mild side effects. Talk to your health care provider if these do not go away within a few days. If you begin to experience more serious reactions, seek medical attention immediately.

More severe side effects include:
If you experience any of these side effects, seek medical attention immediately. These are symptoms of a severe adverse reaction to this medication that require immediate treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Cialis. Cialis can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any alpha-blocker, antifungal, HIV protease inhibitor, or high blood pressure medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.

As with all prescription medications, inform your doctor if you use ED drugs together, or with other drugs you’re taking.
Taking other medications that can interact with Cialis may also have interactions with Cialis. For example, if you take nitrates used for heart failure or nitroglycerin for high blood pressure, then nitrates can interact with Cialis. As with all prescription medications, be sure to tell your doctor if you are taking any of the following:
You may need to take different medications or supplements at once for a few days to a week. You should not take more than one dose of Cialis each day.
You should not take more than one dose of Cialis each day unless special instructions specify it.
If you take Cialis more than once, some side effects may occur. For example, this side effect is more likely to occur when Cialis is taken with a potent anticoagulant.
Cialis contains the active ingredient tadalafil. Cialis is used to treat erectile dysfunction (ED), which is the persistent or inability to achieve a penile erection sufficient for satisfactory sexual performance. Cialis may also be used for purposes not listed in this medication guide.
Cialis is also used to treat symptoms of an enlarged prostate (benign prostatic hyperplasia - ), with or without alpha-blocker treatment.
Cialis is only used if your doctor has already approved it:
Patients taking tadalafil should have a doctor's advice.
Cialis has a different action: it can treat prostate cancer, prevent prostate growth in patients with prostate cancer who take nitrates (such as GTN).
Cialis should not be used in patients with heart problems or patients taking other blood pressure medications. These combination medicines can cause a drop in blood pressure when used with tadalafil, which can lead to dizziness or fainting.
Avoid taking Cialis with:
As with all medicines, Cialis can cause side effects. See the “Other side effects” section for a detailed list. Some side effects may occur that may differ from the side effects listed at NICE. See also “*”.
Like all medicines, Cialis can cause side effects. Side effects are likely to un accepte a patient.
If you take Cialis with a heavy meal, take it at least an hour before or 2 hours after meals to minimize stomach upset. Avoid this mode of taking it.
If you take Cialis with alcohol, avoid alcohol while taking it.
Cialis can also cause side effects such as:
Although most of the side effects of Cialis are related to the symptoms of heart problems or prostate cancer, there are rare side effects related to alpha-blockers.
If you are taking an alpha-blocker medication for high blood pressure, you should avoid this mode of treatment. For example, if you take GTN medication along with Cialis.
If you have any questions about why you have been taking Cialis, a doctor has more information.
Please tell your doctor if you are taking or have taken rilpivirine, or pembociclibus propria.
Rilpivirine is an HIV medication.
Pembociclibus propria is a treatment for breast cancer.
Risperidone prevents an enzyme in the prostate called phosphodiesterase type 5 (PDE5) from breaking down cyclic guanosine monophosphate (cGMP). This causes prostate growth. Pembociclibus propria can cause prostate cancer in women who have received pembociclibus propria prior to menopause.
If you take rilpivirine along with Cialis, you should avoid taking this medication. You should avoid taking other blood pressure medications.
Risperidone can cause nausea, vomiting, stomach pain, dry mouth, and constipation. Tell your doctor if you have had a stomach ulcer or an bleeding disorder.
Tell your doctor if you have or have had high cholesterol or a family history of high cholesterol.
