Tadalafil (Generic Cialis®)

Tadalafil is a generic prescription drug that is used to treat several conditions, namely erectile dysfunction (impotence), as well as enlarged prostate (benign prostatic hyperplasia) and high blood pressure in the lungs (pulmonary arterial hypertension). Tadalafil (like its brand-name counterpart, Cialis®) belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent the enzyme PDE5 from working too quickly. The penis is one of the body parts where this enzyme works.

When Tadalafil (Cialis®) is taken as needed for ED, it can start working in about 30-45 minutes.

Like other ED drugs that are taken as needed for ED, it must be taken in advance of when you plan to be sexually active to give it time to start working. You may also need to plan your medication around meals. This can make it hard to be spontaneous.

Tadalafil can also be taken at a lower prescribed dose at the same time every day. When taken in this way over time, you may find an increased ability to achieve an erection anytime you are sexually aroused. After beginning a daily regimen of Tadalafil, you may be able to have successful intercourse in as early as 4 to 5 days.

One dose of Tadalafil taken as needed for sexual activity can remain effective for up to 36 hours, however peak concentration of Tadalafil in your bloodstream usually occurs between 30 minutes and 6 hours with a median time of 2 hours.

Tadalafil is offered in several different strengths. Tadalafil tablets available through hims are meant to be taken daily and contain 5 mg of Tadalafil and the following inactive ingredients: croscarmellose sodium, hydroxypropyl cellulose, hypromellose, iron oxide, lactose monohydrate, magnesium stearate, microcrystalline cellulose, sodium lauryl sulfate, talc, titanium dioxide, and triacetin.

Your doctor will determine if a once daily dosage is right for you. This will depend on a number of factors, such as your medical health and history. Tadalafil taken as needed for sexual activity is available in several different strengths. Your doctor may start you on a lower dose (eg 10 mg) and increase you to a higher dose or decrease you to a lower dose depending on if it's working and how well you are tolerating it. If you have any questions about dosage or how to take Tadalafil, always consult with your doctor. Only the once daily 5mg dosage is available through hims.

Example oral dosage of Tadalafil for once daily use for ED: Adults—5.0 milligrams (mg) once a day, taken at the same time each day, without regard for the timing of sexual activity.
