Cialis (Tadalafil) – Dosage, Uses, Side Effects, Interactions

Introduction

The drug Tadalafil, also known as Cialis, is used for the treatment of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It is classified under phosphodiesterase type 5 (PDE5) inhibitors, which help relax the smooth muscles in the blood vessels in the penis. This facilitates increased blood flow, ultimately resulting in an erection.

Cialis is available in tablet form, ranging from 2.5mg to 20mg. It is taken orally, typically 30 minutes before sexual activity, and its effects can last for up to 36 hours.

Like all medications, Cialis can cause side effects, including headache, flushing, upset stomach, back pain and muscle aches. Rarely, it can also cause more serious side effects, such as sudden hearing loss and vision changes.

Consult your doctor before taking Cialis, especially if you have a history of heart problems, stroke or low blood pressure. It should not be taken with certain medications, such as nitrates, and should not be used by individuals with severe liver or kidney disease.

Dosage

The recommended dosage of Cialis (Tadalafil) varies depending on the individual’s condition and needs. It is essential to follow a healthcare provider’s advice and not exceed the recommended dosage. Here are some general guidelines for the recommended dosages for different conditions:

1. Benign Prostatic Hyperplasia (BPH): The recommended dose for BPH is 5 mg once a day. It may take up to 4-5 days for the full effect to be seen.

2. Pulmonary Arterial Hypertension: The recommended dose for pulmonary arterial hypertension is 40 mg once daily. This should be taken at the same time each day.

How to take Cialis

The recommended dosage of Cialis can vary depending on several factors, such as the patient’s age, health conditions, and the severity of their symptoms. Here is some information on how to take Cialis:

1. Always follow your doctor’s instructions: Your doctor will prescribe the appropriate dosage for your specific needs. It is essential to follow their instructions carefully, as taking too much or too little can be harmful.

2. Avoid grapefruit and grapefruit juice: Grapefruit can interfere with the way Cialis is absorbed by the body and increase the risk of side effects. It is best to avoid consuming grapefruit or grapefruit juice while taking Cialis.

3. Take up to one dose in 24 hours: Exceeding the prescribed dosage of a medication can raise the likelihood of experiencing adverse effects and may not enhance the drug’s efficacy.

Uses of Cialis

FDA approved uses

The FDA has approved Cialis (Tadalafil) for the treatment of the following conditions:

1. Erectile dysfunction (ED): Cialis has received approval for treating ED, a condition where a man cannot achieve or sustain an erection sufficient for sexual intercourse. The medication works by promoting blood flow to the penis, enabling a man to obtain and retain an erection.

2. Benign prostatic hyperplasia (BPH): Cialis is a medication that is approved to treat the symptoms of BPH, a condition where the prostate gland enlarges non-cancerously. By relaxing the muscles in the prostate and bladder, it can alleviate symptoms like frequent urination and difficulty urinating.

3. Pulmonary arterial hypertension (PAH): Cialis has been authorized to treat pulmonary arterial hypertension (PAH), a form of hypertension that affects the blood vessels in the lungs and heart.
