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.
Added/Advanced
  • : While Cialis can be taken with or without food, combining it with Cialis might exacerbate side effects like headaches or increase heart rate in sensitive individuals.
  • Sildenafil: Though not a direct interaction, combining tadalafil with high-fat meal may worsen side effects like headaches or increase heart rate in sensitive individuals.
  • Lipid Lowering Agents (e.g., Doxylamine, Cialis) can lower blood pressure by increasing the blood flow to the penis, which can help stimulate a smooth reaction in response to an erection. They are usually taken on an as-needed basis, with meals to follow when starting Cialis.
  • Over-the-counter ("OTC") medicines (e.g., Viagra, Levitra) can also affect blood pressure by reducing intestinal blood flow. It is important to consult a healthcare provider before starting any medication with a OTC medicine.

    I have been having a bit of a struggle with a little blue pill for about 2 years now. It is taken to help the penis and makes up for lost sex drive. The problem is I do get a bit tired of it. I was diagnosed with erectile dysfunction on 3rd November 2011 and I was prescribed a Cialis daily. This was not for 4 weeks before the erection lasted. I had my first prescription on 4th February 2012 and it was prescribed to me by a GP. I had been trying for 4 weeks to get my erections to go on for 2 days, but it is getting more difficult to get them. I have tried getting a Cialis daily but it does not go well, at least for now. I also have had a low libido on 2 days. The other days have been very dry. The erection is still there and very hard for 2 weeks. I am now trying to lose it and the libido is back where it was before the erectile dysfunction. I have tried not taking the Cialis daily but trying to lose it, but I have only been able to do so for 2 days and it has been very difficult. I am having a terrible headache, not sleeping well, not eating well, not eating enough and I am not able to take the Cialis daily as it hasnt been taking effect in the morning. I have been told to go to the GP, but I am not able to get a Cialis daily. The Cialis daily does not work and I still have a low libido. I am taking a PDE5 medication for erectile dysfunction.

    Please help, if you need any help.

    Re: Erectile Dysfunction

    Hi Sis: I have a mild form of erectile dysfunction, which is a problem where the penis is unable to get or keep an erection. I have had a couple of my patients with it and had to get it to work, but not with the Cialis daily. I have tried several different things, and it is not helping either. I am trying to lose it and have found the Cialis daily to work, but it has not helped me. I am having a great deal of trouble with it now, but it has not helped me. I will have to try and get a second prescription in the next week. Thanks in advance.Hi, I have been experiencing erectile dysfunction with Cialis for about 3 years now. It has been the same for my last 2 years, so it is not an issue, I am on daily cialis for about 3 months. I have been trying to lose the erection for about 4 weeks now and have only been able to get a couple of them back. I am also taking a PDE5 drug (not Cialis).I have been trying to lose the erection and have had a couple of them back. I have also had problems with blood flow to the penis, but it has not helped with the erectile dysfunction. It has been a couple of weeks before I finally got the last dose back, so it has been a long time since I have had it. I am also in the process of trying to lose it again. I am taking a Cialis daily as well. I am still having problems with the blood flow to my penis, but it does not help with the erectile dysfunction. I also have had a small problem with my bladder. I have been taking a PDE5 drug (not Cialis).It has been a problem for a couple of months, but not completely. I have been taking the Cialis daily for about 2 months now, so it is working, but not as well. I have been able to get it to work for about 4 weeks now, and have only lost it. I have also been taking the Cialis once a week, which does not help with the erectile dysfunction. I also have a small problem with my bladder. I have been taking the PDE5 drug (not Cialis).I have been taking the Cialis daily. I have been very tired, and have had a bad night. The last day of my PDE5 medication has been very dry. My erection is still there. I am still trying to get it to work. I am also a bit of a morning-nourished person and it is difficult to maintain a good erection. I am worried that I am going to have to try to lose it again. Please help.Thank you so much for the reply! I had a bad night last night.
