Tadarise 20 mg contains tadalafil 20 mg and is used mainly for erectile dysfunction. It is manufactured by Sunrise Remedies under the Tadarise brand. It should be prescribed by a doctor who can assess erectile dysfunction, such as: Urologist — the most specialized choice. Andrologist/*****-medicine specialist — particularly for *****-function problems. General physician/family doctor — can also evaluate ED and prescribe tadalafil when appropriate. One important point: 20 mg is not usually the starting dose for tadalafil taken as needed. The FDA-approved Cialis labeling recommends 10 mg initially, with adjustment to 20 mg or 5 mg depending on effectiveness and tolerability. Also, tadalafil must not be taken with nitrate medicines such as nitroglycerin because of the risk of a dangerous drop in blood pressure. If you're deciding between Silagra 50 mg (sildenafil) and Tadarise 20 mg (tadalafil), I can explain the differences in duration, side effects, food/alcohol effects, and which is usually preferred.
