For chronic hepatitis B, it helps bring down the amount of virus in your body, supports healthier liver tests, and can slow damage over time.

Safety Notes You Should Read

Kidney and bone health

Tenofovir can affect the kidneys and lower bone mineral density over time. Your provider may:

• Check creatinine/eGFR and urine tests before and during treatment
• Talk about bone health (calcium/vitamin D, weight‑bearing activity), especially if you’ve had fractures or osteoporosis

Liver considerations

• If you have hepatitis B and stop TDF suddenly, HBV can flare (get worse). Don’t stop unless your clinician says so.
• NRTIs, including tenofovir, have a rare risk of lactic acidosis and severe liver enlargement. If you feel unusually weak, short of breath, or have stomach pain with nausea get medical help.

Who should be cautious

• People with reduced kidney function (dose adjustments may be needed)
• Those on meds that can stress the kidneys
• Pregnant or breastfeeding patients discuss benefits and risks with your provider
• If you live with HIV and are treated for HBV, your clinician will choose a fully suppressive HIV regimen don’t take HBV monotherapy in that situation.

Possible Side Effects

Usually mild and manageable:

• Headache, nausea, stomach upset, diarrhea
• Dizziness, tiredness
• Mild rash

Less common but important:

• Kidney issues (changes in urine, swelling, back/flank pain)
• Bone pain or decreased bone density
• Lactic acidosis symptoms: deep/fast breathing, severe weakness, stomach pain with nausea
• Severe liver problems yellowing skin/eyes, dark urine, pale stools

Drug Interactions (flag these for your prescriber)

• Nephrotoxic meds: High‑dose or chronic NSAIDs, aminoglycosides, amphotericin B, tacrolimus, cyclosporine can raise kidney risk when combined
• Didanosine (ddI): Levels can rise with TDF generally avoided
• Adefovir: Avoid combining with TDF
• Boosted protease inhibitors (atazanavir/ritonavir or cobicistat‑boosted regimens): May increase tenofovir exposure monitor kidneys
• Hep C meds like ledipasvir/sofosbuvir: Can increase TDF levels, especially with boosted HIV regimens monitor as advised.
