Warning
Oral route (Tablet)
Severe acute exacerbations of hepatitis B virus (HBV) have been reported in HBV-infected patients who have discontinued anti-hepatitis B therapy, including tenofovir disoproxil fumarate. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in HBV-infected patients who discontinue anti-hepatitis B therapy, including tenofovir disoproxil fumarate. If appropriate, resumption of anti-hepatitis B therapy may be warranted.

General
In clinical trials, the most common side effects reported with tenofovir alafenamide were headache, nausea, and fatigue.
During controlled clinical trials, the most common side effects reported with tenofovir disoproxil fumarate (DF) in HIV-1-infected patients included rash, diarrhea, headache, pain, depression, asthenia, and nausea. The most common side effects associated with this drug in combination with other antiretrovirals have included mild to moderate gastrointestinal events (e.g., nausea, diarrhea, vomiting, and flatulence) in therapy-experienced patients and mild to moderate gastrointestinal events and dizziness in therapy-naive patients. About 1% of patients in clinical trials discontinued therapy due to gastrointestinal side effects.

Lactic acidosis, hypokalemia, and hypophosphatemia have also been reported during postmarketing experience with tenofovir DF.
Lactic acidosis and severe hepatomegaly with steatosis (including fatal cases) have been reported with the use of nucleoside analogs.
Hypokalemia and hypophosphatemia may occur as a result of proximal renal tubulopathy.[Ref]
Hepatic
Death due to progression of liver disease has been reported in 4% of patients with chronic HBV and decompensated liver disease (n=45) using tenofovir DF.
On-treatment ALT or hepatic flares have been reported in patients with chronic HBV using tenofovir DF. In general, ALT flares occurred within the first 4 to 8 weeks of therapy, accompanied by decreases in HBV-DNA levels, and resolved within 4 to 8 weeks without changes to therapy.
Hepatic steatosis and hepatitis have also been reported during postmarketing experience with tenofovir DF.
Severe acute exacerbations of hepatitis have been reported in patients with hepatitis B after discontinuation of this drug.

Renal
In studies in chronic hepatitis B patients using tenofovir alafenamide, mean serum creatinine increased by less than 0.1 mg/dL.
A confirmed increase in serum creatinine of 0.5 mg/dL was reported in 9% of patients with chronic HBV and decompensated liver disease (n=45) using tenofovir DF; however, since tenofovir DF and decompensated liver disease may have an impact on renal function, the contribution of tenofovir DF to renal impairment in these patients was difficult to ascertain.
Proximal renal tubulopathy generally resolved or improved after this drug was stopped; however, decreased CrCl did not completely resolve in some patients after stopping tenofovir DF. Rhabdomyolysis, osteomalacia, bone abnormalities (infrequently contributing to fractures), hypokalemia, muscular weakness, myopathy, and hypophosphatemia may occur as a result of proximal renal tubulopathy.
Renal failure, acute renal failure, Fanconi syndrome, proximal renal tubulopathy, increased creatinine, nephrogenic diabetes insipidus, and acute tubular necrosis have also been reported during postmarketing experience with tenofovir DF.[Ref]
