Tadalista Professional (tadalafil) for erectile dysfunction, the key point is that the “Professional” version is not necessarily a better travel option—the tadalafil dose matters more. Since you mentioned that 20 mg gives you headaches, I would be cautious about choosing another 20 mg product just because it is marketed as “Professional.” Headache is one of tadalafil’s most common side effects. D DailyMed +1 For travel: Occasional sex: a lower tadalafil dose such as 10 mg may be worth discussing with your doctor. The standard labeling starts as-needed treatment at 10 mg, with 5–20 mg adjusted according to effectiveness and tolerability. D DailyMed Frequent/planned ***** activity: 2.5–5 mg once daily is the usual daily-treatment range, rather than 20 mg daily. D DailyMed Don't combine Tadalista with another tadalafil/PDE5 medicine or nitrate medication. D DailyMed If your main goal is something compact and discreet for a trip, tell me whether you want it for occasional use (e.g., 1–2 times during the trip) or daily use, and I can explain which tadalafil strength would generally make more sense.
