Frequently asked questions
How much does an online GP consultation in Castleknock cost?
A DrCall online consultation starts from €35. That covers your consultation, including a sick cert, repeat prescription or referral where clinically appropriate. Your card is only authorised when you book and is charged once a GP confirms your appointment.
Will my employer accept an online sick cert?
A certificate issued after a genuine consultation with an Irish-registered doctor is normally accepted, but employer policies vary. If you are unsure, check with your employer or HR before you book.
Can you backdate a sick cert for me in Castleknock?
Only if your doctor has a clinical reason, based on your consultation. They cannot backdate a certificate simply because it is requested.
What happens after I book an appointment?
Your request goes to our team, who confirm it or suggest another time. Your card is only authorised at booking and is charged once your GP confirms. You will get an email at each step.
Can I claim an online GP visit on my health insurance?
Some private health insurers offer cashback or cover for GP visits, so check your policy. DrCall consultations are paid for privately by card.
