Cialis (tadalafil) is an oral medication primarily used for treating erectile dysfunction (ED) and the symptoms of benign prostatic hyperplasia (BPH). Recognized for its long-lasting effects, Cialis is unique in its ability to remain effective for up to 36 hours, earning it the nickname “the weekend pill.” The Food and Drug Administration (FDA) has approved Cialis for various uses, allowing men to manage both ED and BPH effectively. Understanding the correct dosage and timing is essential to maximize its effectiveness and minimize potential side effects.

Duration of Action
Cialis can be effective for up to 36 hours, which provides a larger window for sexual activity. Depending on your treatment plan, your doctor may prescribe Cialis to be taken only as needed or on a daily basis. When taken on an as-needed basis, it is generally recommended to take the tablet about 30 minutes to 2 hours before sexual activity for optimal effects. For continuous treatment, daily use may be recommended based on individual health needs.
Dosing Information
Understanding how often to take Cialis, particularly at the 20mg dosage, is crucial for effective treatment.
As Needed
If using Cialis as needed, the usual starting dose is 10mg. Depending on your response, it can be adjusted to 20mg. Important to note:
- Do not take more than one dose within a 24-hour period.
- The maximum recommended dose of Cialis as needed is 20mg, as taking higher doses can increase the risk of side effects.
Daily Use
For those requiring daily treatment for ED or BPH, the recommended dose is between 2.5mg to 5mg, taken once a day. In this case:
- If you are prescribed 20mg for daily use, it’s likely that your doctor is managing your response closely, and they will guide you on frequency and duration.
- Daily dosing can help maintain a steady level of the medication in your system, which may promote more natural erectile responses.
Possible Side Effects
As with all medications, Cialis can have side effects. Knowing what to expect can help manage any experience while on this medication.
Mild Side Effects
- Headache
- Back pain
- Flushing
- Nasal congestion
- Dizziness
- Muscle pain
- Heartburn
- Indigestion
Serious Side Effects
While serious side effects are rare, they may include:
- Prolonged erection (lasting more than 4 hours)
- Sudden loss of vision
- Hearing loss or ringing in the ears
- Chest pain
- Severe allergic reactions such as rash, itching, or difficulty breathing
If you experience any serious side effects, seek medical attention immediately. Always consult your doctor if you notice any unusual symptoms while taking this medication.
Effectiveness of Cialis
Studies show that Cialis is effective for many men with ED. According to research, most men experience improved erectile function when using Cialis as directed. Some studies indicate that men report higher satisfaction and confidence levels with Cialis compared to other ED medications, making it a popular choice among users.
How Cialis Works
Cialis works by inhibiting the enzyme phosphodiesterase-5 (PDE5). This inhibition increases the level of cyclic guanosine monophosphate (cGMP) in the body, leading to relaxation of blood vessels in the penis. As a result, increased blood flow facilitates an erection upon sexual stimulation. Understanding this mechanism can help patients appreciate the importance of sexual arousal in conjunction with medication.
Drug Interactions
It’s essential to discuss all medications you take with your doctor, including over-the-counter medications and herbal supplements, to avoid interactions. Cialis should not be taken with:
- Nitrates (commonly used for chest pain)
- Alpha-blockers (used for BPH or hypertension)
- Other PDE5 inhibitors
- Certain antifungal medications and antibiotics that may affect liver enzymes
Always inform your healthcare provider about all substances you are taking to ensure safe and effective treatment.
Who Should Not Take Cialis
Certain individuals should exercise caution or avoid taking Cialis entirely. These include those with:
- Severe heart conditions such as unstable angina or heart failure
- Low blood pressure or conditions that predispose them to low blood pressure
- Severe liver or kidney problems that would impair drug metabolism
- Allergic reactions to tadalafil or any of the inactive ingredients in the formulation
- History of stroke or major eye surgery
Consult your doctor about your medical history and any other health issues to determine if Cialis is appropriate for you.
Cost of Cialis
The price of Cialis can vary significantly based on factors such as your location, pharmacy, and insurance coverage. Discuss with your pharmacist about any potential savings or need for prior authorization from your insurance provider. Generic versions of tadalafil may also be available at a lower cost, offering a more affordable option.
Considerations for Different Age Groups and Health Conditions
If you are older or have existing health conditions, your doctor may start you on a lower dosage. Always inform your healthcare provider about any existing health issues or medications you are taking so they can tailor the treatment plan to your specific needs. Age and overall health can influence how your body metabolizes Cialis and responds to treatment.
