What is Cialis? Cialis contains the active ingredient tadalafil and is a medication used to treat erectile dysfunction. It offers particularly long-lasting effects compared to the other treatment options available and can produce results for up to 36 hours after taking a single pill to help you get and keep an erection. How to take Cialis? Cialis 36-Hour and Cialis Daily contain the same medication but serve different purposes and are there to be taken differently. How to take Cialis 36 Hour: Take 1 whole tablet with a glass of water 30 minutes to 1 hour before you plan to be sexually active. You can take it with or without food, but be aware that it may take longer to work if taken with a heavy meal. You only need to take Cialis when you are going to be sexually active. How to take Cialis Daily: Take 1 whole tablet with a glass of water at the same time each day. You can take it with or without food as it will not affect the way it works. It is important that you take it regularly every day to ensure you get the full benefit of the medication, so it can be useful to incorporate it into your daily routine (eg with coffee at breakfast). What dose should you take? Cialis 36-Hour comes in two doses, either 10mg or 20mg. It is recommended to start with the 10mg tablet and continue if this is effective, as lower doses have less chance of side effects. If you find that it is not having the desired effect on your erection after several separate attempts, you can try increasing the dose to 20mg. If you're still not satisfied with the results, talk to your doctor about other medication solutions for you. Cialis Daily is available in two strengths of 2.5mg and 5mg.Men usually start at the 5 mg dose and adjust as needed. If you find that you are experiencing side effects or the 5 mg seems to be too strong for you, you can try lowering the dose to 2.5 mg. How long does it take to work? Cialis has a benefit over other erectile dysfunction drugs because it is so fast to work, often effective enough to allow intercourse just 20 minutes after taking the pill. This is because it is more easily absorbed into the body and goes into action sooner. While you can take Cialis with or without food, it may take a little longer to work if you take it with or shortly after a large meal. For Cialis Daily, it may take up to 5 days for the full effect to kick in, as the low dose builds up gradually. However, after this time it will work continuously.
