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. 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.

What should I know about tadalafil before using it?
The dosage varies depending on the condition being treated and whether it’s prescribed for occasional or daily use. For erectile dysfunction, Cialis can be taken occasionally as needed (10 mg, adjusted to 5 mg or 20 mg) or daily (2.5 mg, adjusted to 5 mg). But it should not be taken more than once per day. For benign prostatic hyperplasia, the recommended dose of Cialis for once daily use is 5 mg, taken at approximately the same time every day. Cialis (tadalafil) is a prescription drug used to treat erectile dysfunction and symptoms of benign prostatic hyperplasia. Cialis is available as an oral tablet that you swallow. Cialis is approved by the Food and Drug Administration (FDA) to treat the following: The prescribed Cialis dosage may vary depending on the condition it’s being used to treat. Notify them if you experience any Cialis side effects that may prevent you from taking your medication. There are two dosage options when Cialis is used to treat ED: dosage for occasional (as needed) use and for daily use. With 60 mg cialis occasional use, you’ll take Cialis only as needed. You’ll likely take one 10-mg tablet before sexual activity. Depending on how well the 10-mg dose works for your ED, your doctor may adjust your dose. It may be decreased to 5 mg or increased to 20 mg. You’ll continue to take it only as needed before sexual activity. You should not take Cialis more than once per day. You also should not take more than the recommended maximum dosage of Cialis, which is 20 mg per day. Taking higher dosages of Cialis than this, such as 40 mg per day, raises your risk of serious side effects. Examples of these side effects include very low blood pressure and priapism (a painful erection lasting 4 hours or longer). With daily use, you’ll take one dose of Cialis per day. You don’t need to time your dose to be taken before sexual activity. You should take it around the same time each day. For daily use of Cialis for ED, the usual starting dosage is 2.5 mg per day. If this dosage isn’t effective for you, your doctor may increase your dosage to 5 mg per day. When used for benign prostatic hyperplasia (BPH), the recommended dose of Cialis for once daily use is 5 mg, taken at approximately the same time every day. When Cialis is prescribed along with the drug finasteride for BPH, the recommended Cialis dose for once daily use is 5 mg, taken at approximately the same time every day for up to 26 weeks. If your doctor prescribes Cialis to treat ED along with BPH symptoms, you’ll take Cialis once per day. For this use, the usual dosage is 5 mg per day. You should not take any additional doses of Cialis for occasional use before sexual activity.

If you have certain kidney problems or liver problems, your doctor may prescribe a lower dosage of Cialis for you. This is because with your condition, the usual dosage may raise your risk of side effects from the drug. Depending on how severe your kidney or liver problems are, your doctor may recommend occasional dosing instead of daily dosing to treat ED. You’ll take Cialis by swallowing it, either once per day or occasionally (as needed before sexual activity). The Cialis tablet should be swallowed whole.

Tadalafil (Cialis) is one of the most popular erectile dysfunction (ED) drugs. 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.
Mechanism of Action
The 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.
Alternatives for erectile dysfunction (ED)
(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? 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. You can take it with or without food. With once-daily Cialis, be sure to take it around the same time each day.
Other Uses for ED Medications
(An active ingredient is what makes a medication work.) Cialis belongs to a group of drugs called phosphodiesterase type 5 inhibitors. This article describes the dosages of Cialis, as well as its strengths and how to take it. To learn more about Cialis, including its cost and side effects, see this Cialis overview article. Your doctor will likely start you on a low dosage of Cialis and adjust it over time to reach the right amount for you. They’ll ultimately prescribe the smallest dosage that provides the desired effect. When you’re taking Cialis once a day, there isn’t a best time to take Cialis. But taking your dose around the same time each day helps to keep a steady level of the drug in your body. For occasional (as needed) use for ED, take one Cialis tablet at least 30 minutes before anticipated sexual activity. In most cases, the ability to have sexual intercourse will be increased for up to 36 hours.
