Whether you can take Tadalafil at the same time as your other medications will depend on which medications you are taking.
You are required to complete a short medical consultation questionnaire that asks for any medications that you are prescribed from your GP and will indicate the medications that can’t be taken alongside Tadalafil.
There are several medicines which should not be taken concurrently with Tadalafil. Medicines which can have potentially serious interactions with Tadalafil include :-
• Any alpha-blocker medicines e.g. doxazosin (Cardura), alfuzosin (Xatral), tamsulosin, terazosin, or Flomax, that you can buy in the pharmacy. (These medicines may be used to treat prostate problems or high blood pressure).
• Isosorbide mononitrate, isosorbide dinitrate, or use a GTN spray or tablets
for chest pain or use Rectogesic ointment?
• Nicorandil (Ikorel), used to treat angina
• Cimetidine, used to treat stomach or duodenal (peptic) ulcers
• Theophylline, used to treat asthma
• Antibiotics:- Clarithromycin, Erythromycin and Telithromycin
• Anti-fungals such as itraconazole and ketoconazole
• Seizure medication:- carbamazepine, oxcarbazepine, phenobarbital, phenytoin and primidone
• Heart or blood pressure medication:- disopyramide, amiodarone, quinidine and procainamide
• Anti-viral medication:- telaprevir, atazanavir, retonavir, indinavir, saquinavir and cobicistat
• Recreational drugs:- amyl nitrate (poppers)
If you are taking any prescribed medication from your GP then you can simply write those in the “Is there any other medical information that you think our doctor should know?” section on the medical questionnaire. Then, our doctor will know whether the Tadalafil is safe for you to take.
How to take tablets of Tadalafil inside the bodyTake this medication by mouth at least 30 minutes before sexual activity. The effects can last up to 36 hours. If Tadalafil isn’t compatible with your time, or if you get side effects from the medicine, then you’re most likely to take it before the anticipated sexual activity.
If you’re taking this medication before the anticipated sexual activity, then you should’ve Ist used Hydrea?No, I’m going to need to give you a closer look at this product. You can learn more about it in the “Is there a reason to take this product if you have a known allergy to Tadalafil” section.
It’s not quite as effective as Hydrea, but it works, and it’s not about more than a few minutes before sexual activity is likely to be required.
The active ingredient in Tadalafil is Tadalafil. It’s in the brand name Cialis. We’ll write more on this at.
“Tadalafil” is a drug that’s available with a 4-month prescription, and a 6-month supply with a 90-day supply. It’s important to correct any medication that should be taken 4-6 hours before sexual activity and to understand the side effects of Tadalafil before starting this treatment option.
Tadalafil I. P. T. [Is island] – [Revised on 4/6/2025]
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:
This combination drugs work by relaxing the blood vessels, which helps to increase blood flow and blood pressure in the penis. They can also enhance the blood pressure-lowering effects of tadalafil, leading to side effects like blurred vision, dizziness, or low blood pressure. Cialis (tadalafil) can cause a drop in blood pressure when taken with these medications, which can be dangerous. If you take these medications while taking top-line performance characteristics (such as strength, dosage, and duration) or safety (such as side effects and drug tolerance) while taking top-line medications, consult your doctor for additional drug-food interactions or additional safety information.
Tadalafil belongs to the group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors, primarily used to treat erectile dysfunction (impotence) and benign prostatic hyperplasia (BPH). Erectile dysfunction is the inability to keep a hard and erect penis suitable for sexual activity. Benign prostatic hyperplasia, also called prostate enlargement, is the non-cancerous growth of the prostate gland.
Tadalafil contains ‘Tadalafil’, which works by relaxing the blood vessels in the penis; this allows the blood to flow into the penis when the person is sexually excited. Thereby, it helps to treat erectile dysfunction. Tadalafil relaxes the bladder and prostate muscles, thereby reducing enlarged prostate symptoms such as difficulty in urination and urgent need to urinate.
You are advised to take Tadalafil for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects, such as headache, back pain, muscle pain, pain in the legs and arms, nasal congestion, indigestion, and facial flushing. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Do not take Tadalafil if you are taking nitrates (used to treat angina), riociguat (used to treat pulmonary hypertension) or alpha-blockers; if you have heart problems or stroke, low blood pressure or uncontrolled high blood pressure. Tadalafil is not intended for use in women. Tadalafil may cause dizziness, so drive with caution. Avoid consuming alcohol as it might cause increased dizziness. Tadalafil should not be given to children as safety and effectiveness have not been established. Keep your doctor informed about your health condition and the medicines you are taking to avoid unpleasant side effects.
