Important Tadalafil Interactions Which You Should Know
Tadalafil is prescribed to address Erectile Dysfunction (ED) in men, a condition commonly referred to as sexual impotence.
For some, Tadalafil can be a preferred choice for enhancing or sustaining an erection.
However, as men age, conditions like high blood pressure and heart disease become more common.
Medications used to manage these conditions may interact with Tadalafil.
Some interactions can lead to harmful effects and should be completely avoided, while others need careful monitoring.
In this article, we will learn about some common Tadalafil interactions with drugs, diseases and food that one should be aware of.
What are the important Tadalafil interactions to know about
Tadalafil, a Phosphodiesterase-5 (PDE-5) inhibitor, is widely used for treating ED.
It also serves as a remedy for various medical conditions, including Benign Prostatic Hyperplasia (BPH), with or without ED symptoms.
Regardless of the reason for your Tadalafil use, knowing medical interactions is very important.
Tadalafil is taken by some people on a daily basis, while others use it only when required.
One dose can stay in your system for several days, potentially causing interactions, even if you didn’t combine Tadalafil with another medication on the same day.
To ensure your safety, it’s wise to consult your healthcare provider before introducing a new medication.
Below, we’ll outline eleven of the most prevalent Tadalafil interactions you should know.
Drug interactions
Let’s first understand some of the common Tadalafil and drug interactions:
Nitrates
Nitrates are medicines that treat and prevent chest pain (Angina) caused by heart disease.
It’s important to note that PDE-5 inhibitors like Tadalafil should not be taken with Nitrates.
This combination can be harmful.
Combining these medications can lead to a significant drop in blood pressure, known as Hypotension.
This may cause dizziness or even fainting.
Alpha-blockers
Alpha-blockers are a class of medications used to treat high blood pressure and, in some cases, urinary symptoms related to an enlarged prostate (BPH).
When Tadalafil is taken along with alpha-blockers, it’s important to exercise caution.
Both Tadalafil and alpha-blockers can widen blood vessels, leading to a significant decrease in blood pressure.
This drop in blood pressure can result in dizziness and fainting for some individuals.
- Blood Pressure: Tadalafil/PDE5 inhibitors may lower blood pressure, leading to dizziness or, when combined with blood pressure medications, more severe concerns like a heart attack
- Nitrate Medications: If you’re on nitrate medications for heart conditions, they can be risky with PDE5 inhibitors. In such cases, it’s best to avoid ED medications
Blood pressure medications with Tadalafil
Taking blood pressure medication alongside Tadalafil is common because high blood pressure can contribute to ED.
Various medications are available to lower high blood pressure, including Diuretics (water pills), Angiotensin-Converting Enzyme (ACE) inhibitors, and calcium channel blockers.
When combined with Tadalafil, some individuals may experience a slight drop in blood pressure.
While this interaction may not significantly affect everyone’s blood pressure, exercising caution when using these medications together is essential.
sGC stimulators
Riociguat is prescribed for pulmonary Hypertension, and Vericiguat is used in specific heart failure cases.
Both are soluble Guanylate Cyclase (sGC) stimulators that work by relaxing blood vessels to enhance blood flow.
Like Nitrates, it’s crucial not to take these medications with Tadalafil.
Combining them can lead to a dangerously low drop in blood pressure.
Protease inhibitors
Protease inhibitors are used to treat viral infections like Hepatitis C and HIV.
Ritonavir, when taken with Tadalafil, can increase the levels of Tadalafil in your blood.
Other Protease inhibitors may have a similar effect.
This interaction can raise the risk of side effects like changes in vision, low blood pressure, and prolonged erections.
Your Tadalafil dosage might be adjusted by your healthcare provider when using these medications together, depending on your specific situation.
Anti-infective medications
Some anti-infective medications, like antibiotics and antifungals, can interact with various drugs.
Examples include Erythromycin, Ketoconazole, and Itraconazole.
Just like Protease inhibitors, these medications might raise the levels of Tadalafil in your bloodstream.
This could lead to dizziness and fainting.
Your Tadalafil dosage might also need to be adjusted if you’re taking one of these medications.
Disease interactions
Let’s learn about some common Tadalafil interactions with diseases:
Cardiovascular disease
If you have heart problems that could make sex unsafe, it’s best not to use PDE5 inhibitors.
Doctors should consider how these drugs, which widen blood vessels, might affect those with heart or blood vessel problems.
This applies to individuals with a heart attack, stroke, or serious heart rhythm issues in the past six months and those with extremely low or high resting blood pressure.
It also includes those with unstable angina linked to heart failure or coronary artery disease.
Renal dysfunction
PDE5 inhibitors can stay longer in the bodies of patients with severe kidney problems, leading to the buildup of these drugs.
It’s best to avoid using these medications in people with severe kidney disease or those undergoing renal dialysis.
If these medications are considered necessary for such patients, adjustments to the dosage may be required, tailored to each individual’s kidney health and how well they can tolerate the medication.
Pulmonary disease
The use of Tadalafil tablets for treating Pulmonary Arterial Hypertension (PAH) is not recommended for patients with Pulmonary Veno-Occlusive Disease (PVOD).
This could worsen these patients’ heart and blood vessel conditions.
Food interactions
Let’s delve into some common Tadalafil interactions with food:
Grapefruit interaction
You may have heard about grapefruit affecting medications, and Tadalafil, along with other PDE-5 inhibitors, is no exception.
Combining grapefruit with these medications can, in some cases, lead to a drop in blood pressure.
However, its impact can vary from person to person.
If you consume grapefruit or grapefruit juice frequently, it’s best to consult your healthcare provider to determine how much is safe when taken alongside your medications.
Alcohol
Tadalafil and alcohol both relax your blood vessels.
Mixing them can lead to a drop in blood pressure.
This might make you feel dizzy and increase the risk of falling.
It’s a good idea to limit or avoid alcohol while you’re on Tadalafil.
For guidance on how much alcohol is safe to consume with Tadalafil, consult your healthcare provider.
Conclusion
Tadalafil, a versatile medication used for various conditions, including ED, comes with important interactions to be aware of.
These interactions can range from potentially harmful to those requiring cautious monitoring.
Common interactions include avoiding Nitrates and being cautious when combining Tadalafil with alpha-blockers.
Considering blood pressure medications is also crucial, as high blood pressure often relates to ED.
Additionally, interactions with sGC stimulators, PDE-5 inhibitors, Protease inhibitors, anti-infective medications, grapefruit, and alcohol should be considered.
To ensure your safety and well-being, it’s essential to seek help from your doctor before introducing new medications alongside Tadalafil.
By staying informed and taking the necessary precautions, you can maximize Tadalafil’s benefits while minimizing potential risks.
