As the drug’s active ingredients have a powerful action, you should not abuse the intake of Cialis Black to avoid unpleasant side effects and counter-indications: an intake with excessive doses can give symptoms such as nausea, diarrhea, urticaria, hypertension, palpitations, headaches, insomnia, breast pain, in addition to cases of allergy to the same.
Cialis Black is especially contraindicated for those suffering from hypertension, bleeding, duodenal ulcer, anxiety and severe insomnia. Cialis Black is known to have interactions with certain drugs such as phenelzine (Nardil psychotropic drugs) and Warfarin (Cumadin anticoagulants), oral hypoglycemic agents and insulin. Before intake it is essential to check the origin and the content of ginseng: there are in fact many cases in which it can be found of low quality and cut together with other roots of dubious origin.
If you decide to take Cialis Black, remember to avoid too long periods of intake, with a maximum of 5-7 weeks, after which you will have to follow a period of rest from the next intake.
