Cialis (Tadalafil) for Erectile Dysfunction and BPH: Uses, Dosage, and Safety

Cialis contains tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. It is prescribed for erectile dysfunction (ED), for signs and symptoms of benign prostatic hyperplasia (BPH), and in some patients for both conditions. During sexual stimulation, tadalafil enhances the nitric oxide–cyclic GMP pathway, which relaxes smooth muscle and improves blood flow to the penis. It does not create sexual desire, produce an erection without stimulation, or cure the underlying cause of erectile dysfunction.

ED deserves clinical assessment because it may be associated with cardiovascular disease, diabetes, hypertension, medication effects, hormonal changes, anxiety, depression, or other health concerns. The Cialis price can vary by strength, quantity, pharmacy, insurance coverage, and location. Cost should not determine whether a medicine is appropriate; tadalafil requires a valid prescription where applicable and should be obtained from a legitimate, licensed source.

Indications

Cialis may be used as needed for erectile dysfunction or once daily for erectile dysfunction, BPH symptoms, or both ED and BPH when a clinician determines it is suitable. It is not a treatment for women or children, and it should not be used simply to enhance sexual performance in people without a diagnosed condition. Tadalafil is also marketed under other product names and dosing schedules for pulmonary arterial hypertension; these products are not interchangeable with Cialis for ED or BPH.

Dr. Arthur L. Burnett, a urologist and lead author of the American Urological Association erectile dysfunction guideline, describes ED management as a clinical process that should account for medical, psychological, and relationship factors. This is a reason to obtain appropriate assessment before treatment rather than self-diagnosing or relying on nonprescription sexual-enhancement products. Patients with a valid prescription can buy Cialis 2.5 mg when that once-daily strength matches the regimen selected by their prescriber.

Dosage

Take Cialis exactly as prescribed. For as-needed treatment of erectile dysfunction, a clinician may prescribe a 10 mg starting dose before anticipated sexual activity and adjust it to 5 mg or 20 mg based on response and tolerability. Do not take as-needed tadalafil more than once per day. For once-daily ED treatment, the usual starting dose is 2.5 mg daily and may be increased to 5 mg daily. For BPH or ED with BPH, 5 mg once daily is commonly prescribed. Tadalafil may be taken with or without food.

Do not change the frequency, take an extra tablet after an unsatisfactory response, split tablets, or combine tadalafil with another PDE5 inhibitor. Kidney impairment, liver impairment, age, side effects, and concurrent medicines can change the appropriate regimen. Patients with a valid prescription may buy Cialis 5 mg only when that strength and schedule have been clinically confirmed. The Cialis price should never be a reason to substitute a different strength, interrupt treatment, or obtain medicine from an unverified supplier.

Patients who use tadalafil only when needed may buy Cialis 10 mg when this is the prescribed dose for erectile dysfunction. A clinician may consider a different dose based on individual response, medical history, and interacting medicines. Patients should buy Cialis 20 mg only if their prescriber has specifically selected that dose; 20 mg is not automatically appropriate merely because a lower dose has not produced the desired result.

Safety Information

Do not use Cialis with nitrates or nitric oxide donors in any form, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, or recreational “poppers” containing amyl or butyl nitrite. The combination can cause a severe and potentially life-threatening fall in blood pressure. Do not use tadalafil with riociguat. Tell the prescriber about any allergy to tadalafil or product ingredients.

Before treatment, report chest pain, heart failure, recent heart attack or stroke, unstable angina, low blood pressure, uncontrolled hypertension, serious kidney or liver disease, bleeding disorders, active stomach ulcers, retinitis pigmentosa, a history of vision loss, sickle cell disease, leukemia, multiple myeloma, penile deformity, or previous prolonged erections. Sexual activity can add cardiac strain. People with cardiovascular disease should ask their clinician whether sexual activity and tadalafil are safe for them.

Common side effects include headache, indigestion, back pain, muscle aches, facial flushing, nasal congestion, and pain in the arms or legs. Seek urgent medical care for chest pain, fainting, severe dizziness, sudden vision loss, sudden hearing loss, or an erection lasting more than four hours. Priapism can permanently damage penile tissue without prompt treatment. Stop sexual activity and seek immediate evaluation if chest pain, nausea, or marked dizziness occurs during sex.

Interactions

Tadalafil can interact with alpha-blockers and other blood-pressure-lowering medicines, increasing the risk of dizziness, fainting, or hypotension. Strong CYP3A4 inhibitors, including ritonavir, ketoconazole, itraconazole, clarithromycin, and erythromycin, can increase tadalafil exposure and may require dose or frequency limits. Some medicines that induce CYP3A4 may reduce tadalafil levels. Heavy alcohol intake can also increase the likelihood of low blood pressure, dizziness, or rapid heartbeat.

Give your clinician and pharmacist a complete list of prescription medicines, nonprescription products, vitamins, supplements, and recreational substances before starting treatment. Do not combine Cialis with sildenafil, vardenafil, avanafil, or unregulated sexual-enhancement products. The Cialis price is secondary to a pharmacist’s interaction review and safe dispensing. Contact your prescriber promptly if new medicines are started, your medical condition changes, or troublesome adverse effects occur.
