I took Tadalafil. What is its safety window before a surgery?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am undergoing spinal anesthesia for an inguinal hernia. However, during a party with friends, I accidentally took a 5 mg Cialis tablet. I have heard that this may create complications in anesthesia. I am really tense about whether to go ahead with the surgery or not. Can you please guide me? I am hesitant to tell this to the doctor in front of my family.

Please advise me.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query regarding spinal anesthesia.

The Cialis tablet (Tadalafil 20 mg) should not have any effect on the procedure after a few days. Usually, the drug effect lasts for only 36 to 40 hours. Even spinal anesthesia guidelines advise the stoppage of such drugs for 24 hours prior to surgery only. So you can go ahead with your planned inguinal hernia repair (a common surgical procedure to fix a bulge in the groin that occurs when tissue pushes through a weak spot in the abdominal wall into the inguinal canal).

I hope this helps.

Thank you.
