Tadalafil (Cialis) is primarily prescribed for the treatment of erectile dysfunction (ED), a condition characterized by the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. In addition, tadalafil is effective in alleviating the symptoms of benign prostatic hyperplasia (BPH), including difficulty initiating urination, experiencing pain during urination, and frequent urination emergencies in adult males. Furthermore, tadalafil (marketed under the name Adcirca) is utilized to enhance exercise tolerance in individuals diagnosed with pulmonary arterial hypertension (PAH). This serious health condition involves increased pressure in the pulmonary arteries, leading to symptoms such as shortness of breath, lightheadedness, and fatigue. Tadalafil belongs to a group of medications known as phosphodiesterase inhibitors (PDE). Its mechanism of action consists of increasing blood flow to the penis upon sexual arousal, thereby facilitating an erection. In cases of PAH, tadalafil works by relaxing the blood vessels within the lungs, improving blood flow.
It is crucial to note that tadalafil does not cure erectile dysfunction, nor does it stimulate sexual desire. Additionally, it does not serve as a contraceptive or prevent the transmission of sexually transmitted infections, including HIV.
Tadalafil is available in tablet form and can be ingested orally, with or without food, which may provide a level of flexibility for patients regarding their meal timings.
When taking tadalafil for erectile dysfunction, it is essential to adhere to your healthcare provider's guidance and the instructions provided. Tadalafil can be administered in two primary ways: as a daily maintenance therapy or on an as-needed basis. It’s advisable to discuss with your healthcare provider which regimen best aligns with your lifestyle and health conditions. For those using tadalafil on an as-needed basis, the recommended intake is usually at least 30 minutes prior to sexual activity, with a maximum frequency of one dose in a 24-hour period. Your healthcare provider will help determine the optimal timing for your dose relative to planned sexual activities. Alternatively, tadalafil can be prescribed for once-daily use, irrespective of sexual activity timing. When following a daily regimen, aim to take your dose at the same time each day for consistency. For individuals with certain medical conditions or who are taking other medications, a lower daily dose or less frequent administration may be warranted. Always respect the guidelines provided on your medication label and consult your healthcare provider or pharmacist with any questions or concerns.
If you are prescribed tadalafil for PAH or BPH, it should be taken once daily. For your daily dosage, take all tablets at once and do not split them into separate doses. Aim to take tadalafil at approximately the same time daily to maintain consistent blood levels of the medication. If you are already receiving treatment for BPH, your healthcare provider may suggest discontinuing other medications at least one day before starting tadalafil.
Your doctor may initiate treatment with a moderate tadalafil dosage for erectile dysfunction and then adjust the dose based on your health response. Notify your healthcare provider if tadalafil fails to provide the desired effect or if you experience any adverse reactions.
When using tadalafil for PAH, remember that while it is effective in managing the condition, it does not result in a cure. Continue taking the medication even if you feel improvement, and do not discontinue use without first consulting your healthcare provider.
Feel free to ask your pharmacist or healthcare provider for a copy of the manufacturer’s information leaflet for further understanding of the medication.
Occasionally, tadalafil is utilized for conditions other than those stated. For further information, consult your healthcare provider or pharmacist.
Before Taking Tadalafil
- Notify your healthcare provider and pharmacist if you have any known allergies to tadalafil, other pharmaceuticals, or inactive components within tadalafil tablets. Request a complete list of ingredients from your pharmacist.
- Disclose any pre-existing health conditions, including heart issues, liver or kidney disease, and a history of stroke, as these factors may influence your doctor’s recommendation for tadalafil use.
- Inform your healthcare provider about all medications you are currently taking, including over-the-counter drugs, supplements, and herbal products, as they may interact with tadalafil, leading to adverse effects or reduced effectiveness.
- Be aware of the potential side effects associated with tadalafil and report any persistent or severe reactions to your healthcare provider.

Potential Side Effects of Tadalafil
Common side effects linked to tadalafil include headaches, nausea, indigestion, back pain, muscle aches, flushing, and nasal congestion. Infrequent side effects might involve dizziness or lightheadedness, which typically resolve within a few hours.
More serious but rarer side effects include irregular heartbeats or chest pain. If these occur while on the medication, immediate medical attention is essential.
Other possible effects may involve visual disturbances, such as a tinted blue appearance in visual perception or blurred vision. Rarely, tadalafil may cause priapism, characterized by a prolonged erection lasting more than four hours, which demands immediate medical care.
Some individuals might experience emotional side effects, ranging from anxiety and depression to irritability and difficulties concentrating. If you experience these symptoms, consult your healthcare provider to explore alternative treatment options and necessary adjustments.
Following appropriate guidelines and your doctor's recommendations regarding tadalafil can significantly enhance your sexual performance and alleviate erectile dysfunction symptoms. However, individual responses to the medication can vary, and discussing concerns with your healthcare provider before starting treatment is vital.
Frequently Asked Questions about Tadalafil
1. What is the typical onset time for tadalafil 5 mg and 20 mg tablets?
Tadalafil usually begins to take effect between 30 to 60 minutes after ingestion, with variability among individuals. It is advisable to take the tablet at least one hour before sexual activity to ensure effectiveness. Consuming the tablet alongside a high-fat meal may delay onset.
2. What is the duration of tadalafil’s presence in the body?
Tadalafil can remain effective in the system for up to 36 hours, facilitating multiple sexual encounters within that timeframe. Nonetheless, if taking more than one dose within 24 hours, be aware that tadalafil can remain in the body for as long as 72 hours; thus, avoid taking additional doses within that period to prevent overdose.
3. What starting dosage should I take?
Your healthcare provider will determine the appropriate initial dosage based on your medical history and response to treatment. Generally, the common starting dose is 10 mg, taken as necessary prior to sexual activity, with potential adjustments made to 20 mg or decreased to 5 mg based on tolerance.
4. Are there drug interactions to be aware of?
Yes, tadalafil can interact with certain medications, including those prescribed for high blood pressure or chest pain (such as nitrates), various antibiotics, antifungals, and specific HIV medications known as protease inhibitors. Combining tadalafil with other sedative medications or substances, like alcohol and antihistamines, may increase the risk of lower blood pressure and sedation effects, leading to dizziness or fainting. Always inform your doctor of any medications you are taking before starting tadalafil.
