Tadalista Professional can be taken with or without food, depending on your doctor's instructions. The tablet should be taken 30 to 60 minutes before having intercourse. Both medications can help men achieve and sustain an erection during sexual activity. Neither is more powerful than the other nor can one make you stronger than the other. It is advised that you take Cialis without any prior knowledge. Eating a large meal just before taking Cialis will slow down the rate at which the medicine works. Headaches, migraines, dizziness, allergic skin reactions, redness, rash, raised heart rate, nausea, vomiting, and so on are the most frequent side effects, all of which can be promptly treated with medication.
