What should I avoid when taking Cialis?
Don’t take Cialis with alcohol. Mixing these two substances is likely to result in experiencing negative side-effects of the drug. Grapefruit, grapefruit juice and grapefruit products are know to interact with Cialis, so discuss your diet with your doctor before taking Cialis if it includes some of these products. Do not mix Cialis with other medications used for treating erectile dysfunction (herbal or prescription) unless your doctor tells that it’s safe for you to do that. Do not modify your dosage without asking your doctor first.
