For the daily dose, try to take it at the same time every day. Cialis can last up to 36 hours in the body, but may last up to 72 hours in some cases. Your age, genetics, and whether you have heart, liver, or kidney disease all affect how the drug works and how long Cialis stays in your body.

Let’s look at Cialis, why you should avoid taking too much, and more. Taking 40 mg of Cialis could be dangerous and raise the risk of side effects, such as a sudden drop in blood pressure and priapism. The typical dose is 10 mg for occasional use and 2.5 or 5 mg for daily use. The typical maximum dose of Cialis for ED is 20 mg once a day. If a doctor has prescribed Cialis for pulmonary arterial hypertension, you may be advised to take two 20-mg doses a day.

How it works

But taking that much of the medication should be done only under a doctor’s guidance. While Cialis works for ED by affecting the PDE5 enzyme in the penis, it also affects other PDE enzymes in tissues and cells in other areas of the body. For example, PDE5 is found in tissues in the lungs, kidneys, liver, brain, and platelets. Cialis also affects PDE11, which is found in tissues in the: corpus cavernosum, one of two columns of spongy tissue that runs through the penis Doubling the maximum dose of Cialis to 40 mg can increase the chances of experiencing side effects, which include: Priapism is an erection lasting longer than 4 hours caused by not enough blood leaving the penis, leading to low oxygen levels. The most severe type is ischemic priapism, which requires urgent medical intervention to avoid long-term damage to penile tissue. You may need dose adjustments to avoid side effects.

The dosage of Cialis and how it’s prescribed for you depend on: other conditions you may have, such as diabetes or high blood pressure If you have heart, kidney, or liver disease, it’s important to discuss your ED treatment options with a doctor. You may need a lower dose of Cialis to avoid side effects.

Why is this medication prescribed?

Another reason not to double your dose is the long-lasting effects of Cialis. Cialis’s effects last much longer (up to 36 hours) than those of other PDE5 inhibitors like Viagra (4 to 5 hours). So, Cialis stays in your body and clears slowly. Adding doses on top of what’s already in your system can increase the risk of side effects. It limits the effect of the PDE5 enzyme in the penis, allowing blood vessels in your penis to relax so blood can flow into the penis, helping to get or keep an erection.

Try different timing if you take it as needed: You may need to take Cialis a few times for you to figure out the best timing for as-needed dosing. Don’t take more than one dose in a day. Be consistent for daily use: Some people prefer the daily dose because it allows small amounts of Cialis to always be in your bloodstream, so you can have flexibility with sexual activity.

Tadalafil is unique compared with other PDE5 inhibitors because it can be taken either once daily at a lower dose or as needed at least 30 minutes before sexual activity. This lets you choose which dosing suits your lifestyle needs best. On average, Cialis starts to work in about 30 minutes and can take up to 2 hours to take effect.

The Biggest Practical Difference: Timing and Duration

Second, we always recommend choosing the generic because of its low cost and stronger FDA oversight. With that said, finding the right medication requires visiting with a qualified urologist, ideally specializing in men’s health. Schedule a consultation about correcting erectile dysfunction and understand the treatment options, including medication, shots, and penile implants. Taking 40 mg of Cialis, which is double the dose of the drug, could cause serious side effects. Speak with a prescribing doctor if Cialis is not effective for you.

More common

Cialis is a brand-name version of tadalafil, a popular medication for treating erectile dysfunction (ED). Taking the medication helps you get the maximum effect while avoiding side effects. Reasons not to take 40 milligrams (mg) of Cialis include how the drug works and its duration. Increasing the dose could result in side effects. If you feel your current dosage isn’t working, there may be options to consider. You should also discuss any minor changes in your erections or libido. Addressing signs of trouble early could help treat ED or may lead to an early diagnosis of a condition like cardiovascular disease or diabetes — two common causes of ED, especially in younger people. While you may experience no side effects or complications from taking 40 mg of Cialis, you do run the risk of problems like a sudden drop in blood pressure, which can, in turn, lead to fainting and a possible injury from a fall.

Can I Make a Switch?

Urologists are well-trained in this prevalent condition and can prescribe maximum dosages, which can often be cut in half for a typical starting dose. Further, a urologist can help you find additional options when medications no longer work. You or your urologist likely have a preferred pharmacy; however, if you don’t, or, for example, you are out of town and need to fill a prescription, be sure that they are in the United States and/or are licensed to sell and ship to your state or location. And be sure that the pharmacy is transparent about their business practices, including their pharmacist of record. If you are uncomfortable with their business practices, ask your urologist for a different recommendation or find a pharmacy you feel more comfortable with.

Dosage for erectile dysfunction and benign prostatic hyperplasia (ED/BPH)

There are two straightforward ways to differentiate between generic Tadalafil and a compounded version. First, the generic only comes in tablet form, so it’s compounded if you see sublingual tabs, gummies, mints, or other formulations. There is also no generic combination ED medication – these Tadalafil-Sildenafil combinations are always compounded. Lastly, generic Tadalafil only comes in specific dosages: 5mg, 10mg, and 20mg. Ultimately, when you are seeking treatment for erectile dysfunction, and it’s time to find the right pill, first know that Cialis and Tadalafil are interchangeable. Taking too much Cialis also means any side effects you experience, such as headaches, priapism, and leg or back pain, are more likely to last longer than side effects accompanying a standard dose.
