While the manufacturer suggests that a 30-day supply of daily Cialis should cost about the same as eight pills of 36-hour Cialis a month, there's no way to enforce this. Check your insurance policy and local pharmacies for price information. – By Matthew Solan Executive Editor, Harvard Men's Health Watch As a service to our readers, Harvard Health Publishing provides access to our library of archived content.

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.

| Nitrates Medication Use | Yes | Risk of severe hypotension |

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.
Other Comments
If you need to use a nitrate medicine, take it at least 48 hours after your last dose of tadalafil. Do not drink excessive amounts of alcohol (eg, 5 or more glasses of wine or 5 or more shots of whiskey) when taking tadalafil. When taken in excess, alcohol can increase your chances of getting a headache or dizziness, increase your heart rate, or lower your blood pressure. If you experience sudden loss of vision in one or both eyes, contact your doctor immediately. Check with your doctor right away if you have a sudden decrease in hearing or loss of hearing, which may be accompanied by dizziness and ringing in the ears.

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.
The bottom line
Taking a daily low-dose pill may reduce side effects, though it may reduce effectiveness as well. In studies, the most common daily pill side effects were headache, muscle pain, indigestion, and back pain. Men taking Cialis for daily use can experience a worrisome drop in blood pressure if they drink too much. Ask your doctor if any medications or supplements you take might interact with a daily erectile dysfunction pill, including blood pressure drugs, antifungal drugs, and HIV drugs. Also, men taking nitrate medications are advised not to take any ED drugs. 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. In elderly men, for instance, tadalafil has a slightly longer half-life of roughly 21.6 hours.
- Using tadalafil 10mg daily can help reduce the psychological impact of ED.
- Tadalafil’s effectiveness is dose-dependent, and 10mg is a common maintenance dose.
- Avoid taking other nitrate medications while on tadalafil due to risk of serious interactions.
- Always adhere to prescribed dosages to minimize side effects and optimize benefits.
As a long-lasting ED medication, tadalafil is only recommended for use once per day. For optimal results, it’s recommended to take tadalafil at least 30 minutes before you and your partner plan to have sex. But if you have sex every four hours, you won’t want to use tadalafil every time, as this could be very dangerous. Consult with a trusted healthcare professional for personalized medical advice.
- Tadalafil 10mg has a longer duration of action compared to other ED medications.
- Consistent daily use may help avoid the need for timing medication before intimacy.
- Tadalafil 10mg may also be prescribed for benign prostatic hyperplasia symptoms.
- Side effects of daily tadalafil include headaches, flushing, and nasal congestion.
Contrary to popular belief, tadalafil and other PDE5 inhibitors won’t make you get random erections. Instead, proper use of tadalafil just increases blood flow to your penis, meaning you’ll only get an erection when you receive sexual stimulation or feel sexually aroused. Tadalafil works by inhibiting the effects of cGMP-specific phosphodiesterase type 5 (or PDE5), an enzyme found in the smooth muscle cells of blood vessels. PDE5 plays a major role in regulating the flow of blood to certain parts of your body, including the erectile tissues of your penis.
Dosing & Uses
It is important that you tell all of your doctors that you take tadalafil. If you need emergency medical care for a heart problem, it is important that your doctor knows when you last took tadalafil. If you will be taking this medicine for pulmonary arterial hypertension, it is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
US Brand Name
If you take tadalafil for pulmonary arterial hypertension, do not take Cialis® or other PDE5 inhibitors, including sildenafil (Revatio® or Viagra®) or vardenafil (Levitra®). If you take too much tadalafil or take it together with these medicines, the chance for side effects will be higher. If you experience a prolonged erection for more than 4 hours or a painful erection for more than 6 hours, contact your doctor immediately. This condition may require prompt medical treatment to prevent serious and permanent damage to your penis. This medicine does not protect you against sexually transmitted diseases (including HIV or AIDS).
Recommended Standard Dosages
Use protective measures and ask your doctor if you have any questions about this. It is important to tell your doctor about any heart problems you have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems. Do not use this medicine if you are also using riociguat (Adempas®) or a nitrate medicine, often used to treat angina (chest pain). Some illegal ("street") drugs called "poppers" (such as amyl nitrate, butyl nitrate, or nitrite) also contain nitrates. By inhibiting the effects of PDE5, tadalafil makes it easier for blood to flow to your penis and produce an erection.

Tadalafil (Cialis) is one of the most popular erectile dysfunction (ED) drugs.
Length of treatment
The drug comes in low-dose versions that can be taken daily. This means you can have sex at any time, rather than needing to take a pill from time to time as needed like other ED brands. The sublingual tadalafil starting dose for daily-use Cialis is 2.5 milligrams (mg). If that doesn't work, you can increase your daily dose up to 5 mg. But is this the right approach for you—or are you better off with traditional ED drugs like Viagra, Levitra, or even the nondaily version of Cialis?

If you are contemplating Cialis for daily use, consider these questions and then discuss it with your doctor: If it's two or more times a week, a daily pill might be a reasonable choice, since the drug continually circulates in your bloodstream. A daily pill clears the path for sex at any time—if the drug works for you. (Remember, just like other ED drugs, it may not work for everyone). On the other hand, the 36-hour window offered by the nondaily version of Cialis might offer enough spontaneity. Have side effects of your current ED pill been bothering you?
