Store at room temperature away from moisture and heat. If tadalafil is used as needed, you are not likely to be on a dosing schedule. If you take tadalafil every day and you miss a dose, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Drinking alcohol with this medicine can cause a drop in blood pressure, leading to dizziness or fainting. Grapefruit and grapefruit juice may interact with tadalafil and lead to unwanted side effects. Avoid the use of grapefruit products while taking this medicine. Get emergency medical help if you have signs of an allergic reaction to tadalafil: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

By inhibiting the effects of PDE5, tadalafil makes it easier for blood to flow to your penis and produce an erection.
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Be ready for sex whenever you're in the mood Tadalafil (the active ingredient in brand names Adcirca® and Cialis®) is popular for its long duration and flexibility in dosing (which can be taken daily or as-needed), setting it apart from other erectile dysfunction (ED) meds. It lasts for up to 36 hours. Its multiple dosing options can offer benefits, but they can also make knowing how to take the medication a bit confusing. While the maximum dose of tadalafil for the treatment of erectile dysfunction may give you intense erections, it’s important to choose the right dosage for your individual needs to experience minimal side effects and avoid permanent or serious injury.
In this guide, we’ll break down how tadalafil works, the available dosages, and how to take it for the best results, whether you’re aiming for spontaneity or long-term consistency. Since tadalafil is the longest-lasting medication for erectile dysfunction, it should be treated differently than many other medications on the market. The key reason: A single dose of tadalafil may provide relief from ED for up to 36 hours. If we wade into the science for a moment, that means the half-life of tadalafil is approximately 17.5 hours. That’s a really long time, and it’s only an average. Our guide to PDE5 inhibitors has more information about how tadalafil, sildenafil, and other medications for erectile dysfunction work. There are a number of common use cases for this medication, including: Tadalafil for the symptoms of benign prostatic hyperplasia (BPH) Tadalafil for the symptoms of benign prostatic hyperplasia (BPH) Let’s look at the actual dosages in more detail. The prescription drug is a PDE5 inhibitor, meaning it blocks phosphodiesterase type 5 enzymes that reduce blood flow to the penile tissues. So tadalafil essentially treats erectile dysfunction by increasing blood flow to your penis, making it easier for you to get an erection when you feel sexually aroused. Tadalafil is available in several dosages, from a minimum dosage of 2.5mg (milligrams) all the way up to a 20mg per tablet, the maximum dose of tadalafil in 24 hours. The typical as-needed starting dose of tadalafil is 10mg.
Tadalafil is not approved for use by anyone younger than 18 years old. Tadalafil is usually taken only once per day. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Tadalafil can be taken with or without food.
For erectile dysfunction, take Cialis just before sexual activity but not more than once per day. It can be used up to 36 hours before sexual activity. Cialis can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Do not take Cialis for erectile dysfunction if you are taking Adcirca for pulmonary arterial hypertension. The medication is typically prescribed at this dosage for use as needed before sex for men with mild to moderate ED. And if you begin your ED treatment journey with tadalafil, you’ll almost certainly be prescribed a 10mg dose to start. Most guys with ED who use tadalafil at this dosage are able to have sex successfully. Still, it’s possible that this dosage won’t meet your individual needs. In this case, your healthcare provider may prescribe a higher dose. For all as-needed dosages, you’ll typically want to take tadalafil at least 30 minutes to two hours before you plan to get intimate.
If your erectile dysfunction is fairly mild, or if you develop side effects from using tadalafil at a higher dosage, your healthcare provider may prescribe tadalafil at a dosage of 5mg.
| Aspect | Details | Notes |
|---|---|---|
| Active Ingredient | Tadalafil | Dose: 10mg |
| Drug Class | Phosphodiesterase Inhibitor | Used for erectile dysfunction |
| Typical Onset | 30-60 minutes | Varies among individuals |
| Duration of Effect | Up to 36 hours | Long-lasting effect |
This is the lowest as-needed tadalafil dosage currently available. Although it’s slightly less effective than the 10mg and 20mg dosages at treating ED, it’s also less likely to cause certain side effects, which, for men with heart conditions and those vulnerable to dizziness, can be a necessary precaution for safe and effective use. If you don’t notice any improvements from a 10mg dosage, or don’t experience a big enough improvement to have satisfactory sex, your healthcare provider may prescribe a stronger 20mg dosage of tadalafil. The maximum dosage of tadalafil is 20mg, used as needed for sexual intercourse for men with more severe ED. If you’re prescribed tadalafil at this dosage, it’s likely because smaller doses weren’t giving you the results you were hoping for.
| Medication Type | Interaction Effect | Advice |
|---|---|---|
| Alpha-Blockers | Can cause hypotension | Dose adjustment needed |
| CYP3A4 Inhibitors | Increase tadalafil levels, risk of side effects | Monitor and adjust dose |
| Blood Pressure Meds | Enhanced blood pressure lowering | Use with caution |
Since tadalafil 20mg dosage is a higher dose, it’s important to follow your healthcare provider’s instructions and take your medication no more than once per day. At this dosage, tadalafil is more effective at improving erectile function and helping men with ED have sex successfully. Research shows that a dosage of 20mg is particularly effective for men with severe erectile dysfunction. Clinical trials show that side effects from tadalafil are slightly more common at this dosage than at a lower dosage of 10mg, though the difference in tolerability is relatively small. While tadalafil is available as-needed, it’s also available for once-daily use in much smaller dosages for always-on preparedness for sexual activity. Daily dose tadalafil is available at a dosage of 2.5mg or 5mg tablets. There might be several reasons to go with daily dosages instead of the dosages where you take the medication as needed.
Using tadalafil daily offers several advantages, as we’ve explained in our full guide to daily-use Cialis. However, keep in mind that daily use might change the side effect outcomes for some people. Side effects such as indigestion and flushing may become more frequent with daily use. When used daily, tadalafil should be taken at approximately the same time each day to maintain a stable concentration in the body.

It’s important to know that side effects can increase based on dosage, frequency of use, and whether you’re on any other medications. We’ve covered the numerous (and mostly tolerable) tadalafil side effects in our comprehensive guide, but serious side effects at all dosages can include: Once you and your healthcare provider work out the correct dosage for you, tadalafil should effectively improve your erections and enhance your sexual performance.
