Cialis is a well-known oral medication that contains tadalafil as its active ingredient, specifically designed for the treatment of erectile dysfunction (ED). ED is recognized as the inability to achieve or sustain an erection that is adequate for sexual intercourse. In addition to its primary use, tadalafil effectively addresses benign prostatic hyperplasia (BPH) - a non-cancerous enlargement of the prostate gland that can lead to urinary difficulties, such as increased urgency and frequency in urination among adult males. Furthermore, this medication, which is marketed under the name Adcirca, also plays a critical role in enhancing exercise capacity in patients diagnosed with pulmonary arterial hypertension (PAH), a serious condition associated with increased blood pressure within the pulmonary arteries.
The mechanism of action of tadalafil involves the inhibition of phosphodiesterase type 5 (PDE5), an enzyme that regulates blood flow to specific areas of the body. By blocking PDE5, tadalafil promotes increased blood flow to the penis upon sexual arousal, thereby aiding in achieving an erection. In relation to PAH, tadalafil aids in expanding the blood vessels in the lungs, thus improving overall blood circulation and alleviating symptoms linked to this serious condition. Importantly, it is essential to understand that while tadalafil can assist with the physiological aspects of achieving an erection, it does not function as a cure for ED or enhance sexual desire, nor does it provide protection against sexually transmitted diseases.
Tadalafil is provided in tablet form for oral consumption, allowing for convenient and flexible usage. Patients have the option to ingest it with or without food, accommodating their individual preferences. When prescribed for the treatment of ED, there are typically two distinct regimens for tadalafil administration: on an as-needed basis, generally advised to be taken no less than 30 minutes prior to anticipated sexual activity, or as a daily regimen. A thorough consultation with a healthcare professional is vital to ascertain the most appropriate dosing schedule tailored to individual needs.
When utilizing tadalafil on an as-needed basis, it is crucial to avoid taking it more than once within a 24-hour timeframe. Alternatively, if prescribed for daily consumption, tadalafil can be taken at any time of the day, independent of sexual activity. It is imperative to adhere strictly to the instructed dosage, as healthcare providers may modify the dose based on patient responses and any side effects encountered.
For managing BPH or PAH, tadalafil is customarily prescribed as a daily dose. It is advisable for patients to take their tablets consistently at the same time each day and avoid dividing the doses. If a patient is currently using any prior medications to manage BPH, these may need to be discontinued before initiating treatment with tadalafil, as guided by their healthcare provider.
Precautions Before Taking Tadalafil
- Notify your physician if you possess any known allergies to tadalafil or any other components included in the formulation.
- Thoroughly discuss all medications currently being taken, including nitroglycerin and riociguat, as these substances may interact with tadalafil and lead to severe adverse effects.
- Provide your healthcare provider with a comprehensive list of all prescription and over-the-counter medications, as well as any vitamins or supplements currently being utilized.
- Be forthright about your medical history, particularly concerning cardiovascular conditions, fluctuations in blood pressure, vision or hearing issues, and any episodes of prolonged erections.
- If pregnant, intending to become pregnant, or breastfeeding, consult your healthcare provider prior to commencing tadalafil.

What To Do If You Miss a Dose
