Tadalista CT 20 (tadalafil 20 mg chewable tablet) can be taken on an empty stomach. Food does not significantly affect the absorption or effectiveness of tadalafil, so it works whether you take it before or after meals. This is one advantage of tadalafil compared to some other erectile dysfunction medicines that are more affected by heavy meals. Empty stomach use Safe and commonly taken this way May allow slightly quicker onset in some people Often starts working in 20–45 minutes (chewable form may act a bit faster) With food Light meals: no meaningful change Heavy/fatty meals: may slightly delay onset, but effectiveness remains the same Important notes Avoid or limit alcohol, as it can increase dizziness and lower blood pressure Do not combine with nitrate medicines (like nitroglycerin) due to risk of a dangerous drop in blood pressure
