What happens when you take cialis and dont need it?

Taking Cialis (tadalafil) without needing it can lead to unwanted side effects, such as headaches, flushing, indigestion, and muscle aches. It may also cause a temporary drop in blood pressure, which can result in dizziness or fainting. Additionally, using the medication without a medical need could lead to psychological reliance or misunderstandings about one's sexual health. It's important to use such medications only under a doctor's guidance.
