Interactions

A. Top Drug-Drug Interactions:

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.

Other Drug-Drug interactions:

• Ketoconazole, itraconazole (used to manage fungal infection)
• Protease inhibitors (used to manage HIV infection) Ex. ritonavir, lopinavir
• Phenobarbital, phenytoin, carbamazepine (medicines used for fits)
• Rifampicin, erythromycin, clarithromycin (medicines used for bacterial infections)
• Other medicines used to improve blood flow to the penis (Ex. sildenafil)

B. Drug-Food Interactions:

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:

1. Grapefruit and Grapefruit Juice: Grapefruit can increase the levels of tadalafil in your blood by interfering with its metabolism. This may amplify side effects, such as headaches, dizziness, or low blood pressure. Avoid consuming grapefruit or grapefruit juice while taking Cialis.
2. Alcohol: Drinking alcohol with Cialis can enhance the blood pressure-lowering effects of the medication, leading to symptoms like dizziness, lightheadedness, or fainting. Limiting alcohol intake is recommended while using Cialis.
3. High-Fat Meals: While Cialis can be taken with or without food, consuming it with a high-fat meal may delay its onset of action. Opt for lighter meals if rapid effectiveness is needed.
4. Caffeine: Though not a direct interaction, combining Cialis with high caffeine intake might worsen side effects like headaches or increase heart rate in sensitive individuals.

All drugs for blood pressure work in very low doses. It is important to follow the same guidelines as you use for treatment of erectile dysfunction.

Choosing between Cialis and Staxyn: Cialis is available in low doses and is taken for the treatment of erectile dysfunction. While the effect of Cialis on blood pressure is not completely known, it may be taken if it suffice touffer from heart health. Staxyn is a carefully managed risk-benefit analysis (R. A.) sponsored by T. H. Honasan University.

F.

Using Cialis with a grapefruit or grapefruit juice may enhance the blood pressure-lowering effects of the medications. If you choose to consume a grapefruit or grapefruit juice, discuss your medical history with your doctor and decide on a safe, light, but not high-dose, approach with Cialis. Avoid consuming grapefruit or grapefruit juice while using Cialis.

Here are the key drug-food Interactions:

1. : Antihistamines like diphenhydramine or epinephrine may amplify tadalafil's blood pressure-lowering effects, which can affect its metabolism and increase side effects.
2. : Though not a direct interaction, combining Cialis with grapefruit or grapefruit juice with or without food may enhance tadalafil's blood pressure-lowering effects, which may not be immediate or serious. Advise carefully while consuming a light meal containing alcohol.

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.

Tadalafil vs Cialis: Which is better

Tadalafil and Cialis both come in a Tadalafil prescription (“Tadalafil tablets”) which means they are both good sources of Tadalafil. In our experience some people who take Tadalafil may experience side effects such as headache, dizziness and indigestion. Cialis is usually lower cost than Tadalafil which means it is more established and works in a cheaper way.

If you are taking Tadalafil then you can take it on an daily basis when needed - you may as well take it when you need one or if. Tadalafil is often taken twice a day with no side effects listed in the consultation questionnaire. Cialis does not have any Tadalafil tablets, but there is a generic form of Tadalafil.

Tadalafil is the generic form of Cialis, a drug used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis.
