That means it decreases the activity of phosphodiesterase 5, an enzyme that breaks down a substance called cyclic guanosine monophosphate. The lungs and other parts of the body produce cGMP, which causes arteries to relax and widen. When tadalafil decreases the enzyme’s activity, more cGMP is available to relax or widen the blood vessels inside the lungs. When the blood vessels relax and widen, it’s easier for the heart to pump blood through the lungs, which reduces blood pressure in the lungs. That usually leads to improved exercise ability and wellbeing.

ED dosage for occasional use

The recommended dose for most patients is 40 mg (two 20 mg tablets) once daily, with or without food. Don’t split, crush or chew tablets. Your physician might start you on one tablet a day then move you to the full dose of two tablets daily. The gradual change will allow you to adjust to the medication. A physician must prescribe tadalafil, and your insurance company must approve coverage before you start therapy. If you have a prolonged erection, go to an emergency room or contact your doctor immediately.

Bottom line

Patients shall consult a qualified provider before using Cialis or its generics outside of approved indications. Cialis has earned its place as one of the most trusted medications for erectile dysfunction and benign prostatic hyperplasia, thanks to its long duration of action, flexible dosing options, and well-documented safety profile. Its active ingredient, tadalafil, is also used under other brand names, such as Adcirca, to treat pulmonary arterial hypertension, expanding its utility beyond sexual health. With the expiration of its patent, generic Cialis is now widely available and offers the same therapeutic benefits at a significantly lower cost. Although the Cialis pill may differ in appearance from its generic counterparts, the pharmacological effect is the same when obtained from licensed manufacturers.

Learn about who can and who shouldn’t take this medication: Pregnant and breastfeeding patients Tadalafil hasn’t caused harm to animal fetuses in research studies. However, there hasn’t been adequate research on birth defects in humans. In clinical practice, tadalafil is commonly used in pregnant and lactating women with severe pulmonary arterial hypertension, as the risk of untreated or undertreated PAH is higher than the risk of adverse effects from tadalafil. Children and teens Tadalafil generally seems safe and effective for pediatric patients. Although clinical trials for pediatric PAH patients have been small and included people with a wide range of ages and diseases, the sixth World Symposium on Pulmonary Hypertension in 2019 recommended PDE5 inhibitors in its pediatric PAH treatment algorithm.

Release Form and Composition

Cialis (tadalafil): Uses, side effects, and more. U.S. Department of Health and Human Services. Tadalafil – Uses, dosage, side effects, and precautions. Tadalafil is used to treat pulmonary arterial hypertension, also known as Group 1 pulmonary hypertension.

What should I know about tadalafil before using it?

The goal of this therapy is to improve exercise ability. The Food and Drug Administration approved Adcirca in 2009 to treat PAH. Cialis, another form of tadalafil, is approved to treat erectile dysfunction but not PAH. Tadalafil isn’t available in an intravenous form. If you are hospitalized and can’t take oral medications, your doctor may substitute intravenous sildenafil for tadalafil. People with liver disease There is limited research on tadalafil for people with liver disease. For those with mild or moderate liver disease (Child Pugh Class A or B), doctors should consider starting tadalafil at 20 mg once daily. People with severe liver disease (Child Pugh Class C) should avoid tadalafil. People with kidney disease People with mild to moderate kidney disease (creatinine clearance 31 to 80 ml/min) should start tadalafil at 20 mg once daily and increase to 40 mg once daily based on how well super active cialis they tolerate the medication and side effects. People with severe kidney disease (creatinine clearance greater than 30 ml or on dialysis), generally should avoid tadalafil.

Key Takeaways: Cialis vs Tadalafil

The two primary regimens are on-demand use and once-daily administration, and the chosen Cialis dosage determines how the drug performs in the body. For erectile dysfunction, on-demand use typically begins with a 10 mg tablet, taken 30 to 60 minutes before anticipated sexual activity. If needed, this can be adjusted to 20 mg for a stronger effect or reduced to 5 mg in individuals who experience side effects. Thanks to its long half-life of 17.5 hours, Cialis can remain effective for up to 36 hours, allowing for more flexibility than shorter-acting PDE5 inhibitors like sildenafil. Alternatively, Cialis can be taken in lower doses (2.5 mg or 5 mg) once daily, at the same time each day.

What should I tell my healthcare provider before using tadalafil?

This method ensures a steady level of tadalafil in the bloodstream and supports spontaneous sexual activity without the need to plan around the timing of the pill. Daily dosing is also the preferred option for men with both erectile dysfunction and benign prostatic hyperplasia (BPH). Beyond its use in sexual health, tadalafil is also used to treat pulmonary arterial hypertension (PAH), but under a different brand name: Adcirca. In this context, tadalafil is prescribed at higher doses (typically 40 mg per day) to relax blood vessels in the lungs and improve exercise capacity. It may also be prescribed alongside riociguat (Adempas) in treatment-resistant cases, though this combination requires close monitoring. Severe kidney disease increases the amount of tadalafil in the bloodstream, even when patients are on dialysis.

Cialis Boxed Warnings

Whether for ED, BPH, or PAH, the decision between daily and on-demand tadalafil use depends on medical history, treatment goals, and patient preference, making consultation with a healthcare provider essential. While Cialis (tadalafil) is officially approved only for use in adult men, its mechanism of action has led to research exploring potential applications in female and pediatric populations, especially in the context of pulmonary hypertension and certain urological conditions. However, it’s critical to clarify that Cialis is not approved for use in women or children for sexual dysfunction or urinary symptoms. In women, tadalafil has been studied as a treatment for pulmonary arterial hypertension (PAH), where it functions similarly to its role in men—dilating blood vessels to reduce pulmonary pressure and improve oxygen delivery. Clinical trials have also explored tadalafil for managing interstitial cystitis and overactive bladder, but these uses remain investigational and are not included in current labeling.

Tadalafil dosage guide: key rules

There is growing public interest in using generic Cialis (tadalafil) for low libido in women, but this is not an FDA-approved indication. Unlike erectile dysfunction, female sexual desire involves more complex hormonal, neurological, and psychological pathways that PDE5 inhibitors like tadalafil do not effectively target. For women with diagnosed hypoactive sexual desire disorder (HSDD), FDA-approved medications include flibanserin (Addyi) and bremelanotide (Vyleesi), both of which act through different neurochemical pathways and are specifically studied in female populations. Using tadalafil off-label in women should be approached with caution, especially given the lack of robust safety and efficacy data in this group. Until more research is completed, tadalafil remains a drug primarily indicated for men, with emerging but still experimental roles in select non-male populations.
