Are there any side effects when using Tenofovir Cipla 245mg and Haifischknorpel at the same time?

Ask
Hello pharmacist!
I am taking the hepatitis B antiviral drug Tenofovir Cipla 245mg but I also have knee pain and am using Haifischknorpel (the shark). So the pharmacist asked me, if I use Tenofovir Cipla 245mg and Haifischknorpel at the same time, are there any side effects?
Looking forward to the pharmacist's advice, thank you!

Hello!
With the question "Are there any side effects when using Tenofovir Cipla 245mg and Haifischknorpel at the same time? ”, the pharmacist would like to answer as follows:
Haifischknorpel shark cartilage is a functional food, including ingredients: Shark cartilage extract, Chondroitin sulfate and Glucosamine. These ingredients are unlikely to interact with the hepatitis B antiviral drug Tenofovir you are taking. Therefore, you can use these two drugs together.
Regarding hepatitis B disease, you should have regular check-ups (at least every 6 months - 1 year) with a Hepatologist - Biliary specialist to monitor the progress of the disease and use hepatitis B antiviral drugs regularly. as directed by the doctor.
Regarding knee pain, if this condition persists or worsens, you should visit a Musculoskeletal - Joint specialist for the most effective advice and treatment. During the use of the drug, you need to pay attention to monitor the body's abnormal reactions (such as urticaria, itching, digestive disorders, ...) to be able to visit the doctor and handle it promptly. if you experience any of the above undesirable effects.
If you still have questions about taking Tenofovir Cipla 245mg and Haifischknorpel at the same time, are there any side effects, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
