What Is Cialis & How Is it Used?
Cialis is a medication primarily prescribed for the treatment of erectile dysfunction (ED) and belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil, the active ingredient in Cialis, works by inhibiting the action of PDE5 enzymes, which are responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the erectile tissue.
By blocking PDE5, Cialis increases cGMP levels, relaxing the smooth muscles and improving blood flow to the penile arteries. This enhanced blood circulation facilitates the achievement and maintenance of an erection in response to sexual stimulation. Notably, Cialis stands out among its counterparts due to its prolonged duration of action, with effects lasting up to 36 hours, earning it the colloquial name “the weekend pill.”
Cialis is commonly used as an FDA-approved medication to treat:1
- Erectile dysfunction (ED)
- Benign prostatic hyperplasia (BPH)
Cialis can also have off-label (non-FDA-approved) uses for treating:1
- Pulmonary arterial hypertension (PAH)
- Management of Raynaud’s phenomenon (MRP)
- Female sexual dysfunction (FSD)
However, it’s crucial to note that the FDA does not officially approve using Cialis for these off-label purposes, and individuals should only take the medication under the guidance and supervision of a qualified healthcare professional.
For How Many Hours Does Cialis Work?
Cialis typically takes effect within 30 minutes to an hour after ingestion. However, the onset time can vary among individuals, influenced by metabolism, food intake, and overall health. The duration of Cialis’ effects provides a 36-hour window of opportunity for sexual activity compared to other medications in the same class.
Cialis comes in different formulations that affect the drug’s speed of action. The standard tablet is taken as needed, while the daily use version is designed for regular low-dose administration. The on-demand formulation is preferred by those needing immediate relief or spontaneity, while the daily use option offers a consistent approach. The choice between formulations depends on individual lifestyle, preferences, and symptom management needs.
The effects of Cialis can include:2
- Headache
- Dyspepsia
- Back pain
- Myalgia
- Nasal congestion
- Flushing
- Pain in limb
How Long Does it Take for Cialis to Peak?
Cialis reaches peak concentration in the blood about 2 hours after ingestion, but the time to reach peak effectiveness varies due to factors such as metabolism and food in the stomach.
Cialis is known for its prolonged 36-hour window of opportunity. This flexibility allows individuals to engage in sexual activity without strict adherence to a narrow timeframe. Users should plan accordingly to optimize its effectiveness for their specific needs.
How Long Does Cialis Stay in Your System?
Cialis is a medication that stays in the body for up to five days due to its long half-life of approximately 17.5 hours. If someone is undergoing a drug test, they should be aware that Cialis may be detected by specialized tests, even though it is not usually screened for in standard drug tests. Cialis can accumulate in the body and affect drug test results. Communicate with healthcare professionals or testing authorities to ensure accurate interpretation.
- Urine: 3-5 days after the last dose2
- Blood: about 2 to 3 days after the last dose2
- Saliva: 24-48 hours after the last dose2
- Hair: The drug may be traceable in hair follicles for up to 90 days2

The ‘Cialis Window’
The ‘Cialis window’ refers to the duration of time when the medication Cialis is active in the body and can assist in achieving erections in response to sexual stimulation. Cialis, a phosphodiesterase type 5 (PDE5) inhibitor, is commonly prescribed for the treatment of erectile dysfunction. Unlike some other medications in its class, Cialis has an extended half-life, meaning it remains in the system for a more prolonged period.
Cialis is known as “the weekend pill” for providing a longer timeframe for sexual activity without immediate planning. Its flexibility has made it a popular choice for managing erectile dysfunction.
Factors Affecting How Long Cialis Stays in the Body
Several factors can impact how long Cialis stays in someone’s body. One of the most significant factors is age. As people get older, it may take longer for the body to eliminate the drug, resulting in a longer duration of action.
Factors affecting how long Cialis stays in your body include:2
- Metabolic rate: The speed at which the body metabolizes substances can vary among individuals. Those with a faster metabolism may process Cialis more quickly, affecting both its onset of action and overall duration.
- Food intake: Taking Cialis with or without food can influence its absorption rate. Consuming a heavy or high-fat meal with the medication may delay its onset of action as the body takes more time to absorb the drug.
- Age: Age can play a role in drug metabolism and elimination. Older individuals may experience a slightly prolonged duration of Cialis compared to younger users.
- Liver function: Since the liver is responsible for metabolizing Cialis, any impairment in liver function can affect how quickly the body processes and eliminates the drug.
- Other medications: Concurrent use of medications that interact with the same metabolic pathways as Cialis can impact its effectiveness. Some medications may enhance or inhibit the effects of Cialis.
Cialis for Daily Use Vs. As-Needed
Cialis has two options for treating erectile dysfunction: a lower-dose daily option and a higher-dose as-needed option. The daily option involves a smaller amount of tadalafil taken regularly for consistent improvement in erectile function. The higher-dose option is taken just before sexual activity.
Choosing between a lower-dose daily regimen and a higher-dose as-needed option depends on individual preferences and lifestyle. The former provides consistent support, while the latter offers more flexibility and rapid onset of action in managing erectile dysfunction.
How Long Cialis Lasts Vs. Other ED Medications
Cialis, Viagra, Stendra, and Levitra, are medications for erectile dysfunction, but they differ in duration of action.The choice depends on individual preferences, onset and duration of action, side effects, and medication interactions. Consultation with a healthcare professional is recommended.
Lifestyle Tips for Maximizing Cialis Effectiveness
Cialis dosage and timing are crucial to making the medication more effective. For the higher dose, take it 30 minutes before sex. For the lower dose, take it consistently to maintain a steady level in the system and support erectile function.
Dietary factors impact Cialis absorption and effectiveness. Taking it with a high-fat meal may delay onset, while a lighter meal or taking it on an empty stomach can optimize absorption. Excessive alcohol intake can also decrease effectiveness and increase risks. Consultation with healthcare professionals is recommended to optimize the experience.
