Cialis is used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Cialis is an oral medication that works by increasing blood flow to the penis.
It is important to take Cialis exactly as your doctor has told you. Cialis is available in tablet form and is taken orally. The dosage is based on your medical condition and response to treatment. It is important to follow your doctor's instructions when taking Cialis and to use this medication only when needed.
Cialis is available in different strengths and forms. The recommended starting dose is 20 mg, taken as needed approximately one hour before sexual activity. Depending on your response, the dose may be increased to a maximum of 40 mg or decreased to 20 mg, but always follow your doctor's instructions.
It is not possible to know the exact amount of Cialis that your doctor prescribed. Your doctor may tell you to take it with a meal or two before taking it as directed.
Cialis is a prescription medication used to treat erectile dysfunction (ED) in men. Cialis is used to treat erectile dysfunction in men who are unable to get or maintain an erection firm enough for sexual activity. Cialis is also used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate.
You should not take Cialis if you are allergic to any of its ingredients. Before taking Cialis, your doctor should check your blood pressure, heart function, and renal function. Do not take Cialis if you have severe heart failure or high blood pressure, or if you are taking other medications that may interact with Cialis. Cialis can also cause an allergic reaction when taken with alcohol.
Before using Cialis, tell your doctor if you have high blood pressure, diabetes, high cholesterol, high blood pressure, heart disease, kidney disease, liver disease, or are taking any other medication.
Cialis can also affect the way other medications work, such as alpha blockers, diuretics, and anti-hypertensive drugs, which work by increasing the amount of urine produced. It is important to note that Cialis should not be used if you have high blood pressure, heart disease, or liver disease.
Taking Cialis with certain other medicines may impair your ability to achieve an erection. This may include taking Cialis with certain other medicines, such as riociguat, sildenafil, or tadalafil.
Cialis may also reduce your ability to have sexual contact, especially if you have heart problems. Do not take Cialis if you are using a prescription medication for erectile dysfunction. Talk to your doctor about your medical history and any medications you are currently taking.
Cialis should not be used in the following cases:
• Allergic reaction: If you have an allergy to Cialis or any other medications containing the active ingredient tadalafil, stop taking Cialis and seek medical attention right away.
• Urethral and/or rectal bleeding: If you experience a urine pregnancy while using Cialis, stop taking Cialis and seek immediate medical attention.
• Bladder or prostate cancer: If you are taking or have recently taken riociguat, stop taking Cialis and inform your doctor of any recent medical history.

Cialis can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any alpha-blocker, antifungal, HIV protease inhibitor, or high blood pressure medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.

You should know that Cialis cannot be taken by everyone, so informing your doctor of any new or any health changes you plan to make before starting treatment with this medication is not recommended. If you have had an allergic reaction to Cialis or any of the ingredients in Cialis, do not use any other ED treatment besides Cialis.
You should also not take Cialis if you have had a heart attack, irregular heartbeat, chest pain with your breathing, or if you are pregnant or intend to become pregnant. Cialis cannot be used by everyone, so do not take Cialis if you have had a heart attack, irregular heartbeat, chest pain with your breathing, or if you are breastfeeding.

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:
Tadalafil has another drug-food interaction, and this time hemi (halal) tadalafil is interactions with alcohol and grapefruit juice. While hemi can be taken with or without food, regular intake of food or alcohol in conjunction can reduce the effectiveness of Cialis.
When using Cialis with grapefruit and grapefruit juice, the medications working together should be avoided.
