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.

If you experience any side effects or have any questions, consult your doctor.

F.

Cialis (tadalafil) can interact with certain foods and beverages, so using it in conjunction with those can be a dangerous combination. Some medications other than tadalafil contain phosphodiesterase type 5 (PDE5) inhibitors such as:

  1. Alcohol diuretics (used to manage fluid depletion) Tadalafil can also enhance the blood pressure-lowering effects of the medication, which can make symptoms of fainting or dizziness worse. Do not drink alcohol with Cialis.
  2. Other antihypertensive medications (e.g., atenolol, propranolol, lithium, potassiumirenes) Tadalafil can be used with an alpha-blocker to reduce blood pressure.
  3. Other anti-fungal medications (e.g., vinblastine, mycophenolate mofetil)
  4. Other antidepressants (Ex.

    Description

    Viagra Tablets in PakistanPkcs 100mg in PakistanViagra Tablets in Pakistan is a prescription medicine used to treat erectile dysfunction (impotence) in men. It is the only effective drug that contains sildenafil citrate, the same active ingredient found in Viagra. This drug works by increasing the blood flow to the penis. This increase is achieved by inhibiting the enzyme phosphodiesterase. The enzyme is responsible for the degradation of cyclic guanosine monophosphate (cGMP). When cGMP is damaged, it causes the smooth muscles in the blood vessels of the penis to relax and widen. This causes an erection to take place. Sildenafil citrate increases blood flow to the penis. When Viagra Tablets in Pakistan is taken by men who have a weak libido, it may result in impotence. However, the efficacy of Viagra Tablets in Pakistan remains to be determined. It is also important to note that Viagra Tablets is a prescription medicine that must be taken by a doctor. This medication should only be used under medical supervision.
