Does Truvada cause Phosphorus deficiency ?
Jun 4, 2010
I have been on Reyataz, Truvada & Norvir for a couple of years now. However during my last regular blood-work check-ups my doctor noticed that my "Phosphorus" level was low. He repaeted the blood test several times and added a couple of spot urine tests as well as a 24 hour urine collection. He is now prescribing me "PHOSPHA 250mg NEUTRA" I'm having stomach bloating, weakness & diarrhea. How long must I take this "PHOSPHA 250" & will I eventually have to switch from Truvada ?
Response from Dr. Henry
For some patients the tenofovir can cause renal problems including phosphate loss in urine in a small subset of patients. Monitoring overall renal function including checking for protein in urine is warranted with possible switch off the Truvada if the problem progresses. KH
