Cialis: The Essential Guide to Use, Dosage, Benefits, and Safe Online Purchase
What Is Cialis?
Cialis, known by its generic name tadalafil, is a prescription medication belonging to the class of phosphodiesterase type 5 (PDE5) inhibitors. It is primarily used to treat erectile dysfunction (ED) in men, benign prostatic hyperplasia (BPH), and occasionally pulmonary arterial hypertension. Cialis is unique among ED medications due to its long duration of action—up to 36 hours—earning it the nickname “the weekend pill.”
| Brand Name | Generic Name | Class | Duration of Effect |
|---|---|---|---|
| Cialis | Tadalafil | PDE5 Inhibitor | Up to 36 hours |
How Does Cialis Work?
Cialis enhances natural erectile responses by relaxing muscles and increasing blood flow to the penis. The active ingredient, tadalafil, inhibits the PDE5 enzyme, leading to elevated levels of cyclic guanosine monophosphate (cGMP). This, in turn, results in smooth muscle relaxation and increased blood flow during sexual stimulation.
- Mechanism of Action: Inhibits PDE5 enzyme
- Effect: Improved blood circulation in the penis
- Result: Enhanced erection during sexual stimulation
Who Should Use Cialis?
Cialis is suitable for men with:
- Erectile Dysfunction (ED): Inability to achieve or maintain an erection sufficient for satisfactory sexual performance.
- Benign Prostatic Hyperplasia (BPH): Symptoms such as urinary urgency, frequency, or weak stream.
It’s essential to consult a healthcare provider to determine if Cialis is right for you, especially if you have cardiovascular conditions, severe kidney or liver impairment, or are taking nitrate medications.
How to Take Cialis: Recommendations and Dosage
Always take Cialis exactly as your doctor prescribes. Dosage may vary based on indication, age, and overall health condition.
| Condition | Typical Starting Dose | Frequency | Notes |
|---|---|---|---|
| Erectile Dysfunction | 10 mg | Prior to sexual activity, as needed | May increase or decrease based on response; max 1 per day |
| Daily Use for ED | 2.5 mg – 5 mg | Once daily | Same time every day, independent of sexual activity |
| BPH | 5 mg | Once daily | With or without ED |
Tips for Maximum Effectiveness
- Take with or without food (diet does not affect absorption)
- Allow 30-60 minutes for onset of action
- Alcohol may reduce effectiveness and increase risk of side effects; limit intake
- Do not take with other PDE5 inhibitors or nitrate medications
