Daily vs On-Demand Tadalafil: Which Should You Choose?

Many patients ask me, "Would taking it every day be better?" or "If I take it daily, will my body get used to it?" Both patterns have their place. Neither is better for everyone; it depends on how you live and what other health conditions you have.

Two ways to use tadalafil

Tadalafil is a long-acting PDE5 inhibitor, so it can be used in two ways, which is harder with the other drugs in the group. Read the basics in Tadalafil (Cialis): how it works.

Benefits and limits of daily use

Benefits

• No planning or timing; intimacy can happen naturally
• Removes the stress of "waiting for the pill to kick in", which helps a lot for men with erection anxiety
• Treats urinary symptoms from an enlarged prostate (BPH) at the same time
• Some research suggests it may help the function of the blood vessel lining, but the evidence is not strong enough to say it "restores blood vessels" or cures ED

Limits

• You have to take it every day; forgetting often gives inconsistent results
• Side effects such as headache or back pain can occur even on days without sex
• Monthly cost may be higher if you don't have sex often
• Because the drug is always in your system, you must be careful about nitrates at all times

Benefits and limits of on-demand use

Benefits

• Only taken on days you want it; suits men who have sex less often
• A clear effect during the window you need
• On days you don't use it, there is no drug in your body

Limits

• You need to plan ahead; forgetting or taking it late can mean missing the moment
• Some men find it feels unnatural, or their partner feels everything has to be planned
• The dose per occasion is higher, so side effects per occasion are greater

Who suits which pattern

• Sex twice a week or more, or wanting everything to feel natural: daily use is often a good fit
• Frequent urination or feeling you haven't emptied your bladder because of an enlarged prostate: daily use gives two benefits at once. Read about health at this stage of life in Men's health after 50
• Sex less often or in phases: on demand is better value
• Significantly reduced kidney function: daily use is usually not recommended, and the doctor will choose a safer option

Some men start with one pattern and switch to the other as their life changes. If you have questions about on-demand doses, see Tadalafil 10 mg vs 20 mg.

Original brand vs generics: is there a difference?

The original brand (Cialis) and the generics registered in Thailand contain the same active drug, tadalafil, and must pass bioequivalence testing to show they are absorbed in a similar way. The main differences are the brand, the look of the tablet and the price. The choice therefore comes down to convenience and budget, with a doctor's assessment. What you should avoid is unregistered medicine or medicine sold through channels you cannot verify.

Precautions for both patterns

• Tell your doctor about all your medicines, including blood pressure medicines, prostate medicines and HIV medicines
• Go to hospital immediately if an erection lasts more than 4 hours
• Have regular health check-ups, because ED can be linked to diabetes and high blood pressure

Let the doctor help you choose
