FAQs

Is telemedicine safe for all health issues?

Telemedicine is safe for many health concerns but not all. It works well for minor illnesses, chronic condition management, and mental health support. However, it is not suitable for emergencies or conditions needing physical exams or tests. Always seek in-person care if you have serious symptoms.

Do I need special equipment for a telemedicine visit?

Usually, a smartphone, tablet, or computer with a camera and microphone is enough. A stable internet or phone connection helps ensure clear communication. Some visits may require specific apps or platforms, so check instructions from your provider.

Can telemedicine replace my regular doctor visits?

Telemedicine can complement but not fully replace in-person care. It is useful for follow-ups and minor issues but some health needs require physical exams or procedures that only in-person visits can provide.

What if I don’t have internet access?

Many telemedicine services also offer care by phone. If neither is available, seek local healthcare options. Telemedicine aims to increase access but may not be suitable for everyone depending on technology availability.

Will my information be private during telemedicine?

Healthcare providers use secure platforms designed to protect your privacy. However, ensure you are in a private space and use trusted devices to keep your information safe during the visit.
