What is vemlidy in pharmacology?
Vemlidy is a substrate of P-glycoprotein (P-gp) and BCRP. Drugs that strongly affect P-gp and BCRP activity may lead to changes in tenofovir alafenamide absorption (see Table 4 ). Drugs that induce P-gp activity are expected to decrease the absorption of tenofovir alafenamide, resulting in decreased plasma concentrations of tenofovir alafenamide, which may lead to loss of therapeutic effect of Vemlidy. Coadministration of Vemlidy with other drugs that inhibit P-gp and BCRP may increase the absorption and plasma concentration of tenofovir alafenamide.
How many mg of Vemlidy are in a bottle?
Vemlidy tablets containing 25 mg of tenofovir alafenamide are yellow, round, film-coated, debossed with "GSI" on one side and "25" on the other side. Each bottle contains 30 tablets (NDC 61958-2301-1), a silica gel desiccant, polyester coil, and is closed with a child-resistant closure.
What should be assessed before vemlidy?
Prior to or when initiating Vemlidy, and during treatment with Vemlidy on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus [see Warnings and Precautions (5.3) ].
Can you take vemlidy after hemodialysis?
On days of hemodialysis, administer Vemlidy after completion of hemodialysis treatment. Vemlidy is not recommended in patients with ESRD who are not receiving chronic hemodialysis [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].
Does vemlidy need to be adjusted?
No dosage adjustment of Vemlidy is required in patients with estimated creatinine clearance greater than or equal to 15 mL per minute, or in patients with end stage renal disease (ESRD; estimated creatinine clearance below 15 mL per minute) who are receiving chronic hemodialysis.

Tenofovir Alafenamide Efficacy in Clinical Trials in Adolescents and Children
- TAF is available as a component of several fixed-dose combination (FDC) tablets. These FDC tablets are listed in Appendix A, Table 1 and Appendix A, Table 2. Descovy, an FDC tablet that contains FTC and TAF (FTC/TAF), is approved by the U.S. Food and Drug Administration (FDA) for use in children who weigh ≥14 kg to <25 kg at a dose of FTC 120 mg/TAF 15 mg and for child…
Pharmacokinetics
- TAF-containing pills are smaller than their TDF-containing counterparts, a significant advantage for some pediatric patients who may have trouble swallowing larger pills (see Appendix A, Table 2). EVG/c/FTC/TAF contains TAF 10 mg, whereas FTC/TAF and FTC/RPV/TAF contain TAF 25 mg. BIC/FTC/TAF is available in two strengths: one containing TAF 15 mg for children aged ≥2 y…
Toxicity
- Both TDF and TAF are prodrugs of the NRTI TFV. After oral administration, TDF is well absorbed13,14 and is so rapidly metabolized to TFV that TDF itself cannot be measured in blood (even when plasma is sampled within 5 minutes of administration).15TFV is the main compound that is measurable in plasma after TDF administration. From the bloodstream, TFV enters cells …
Indications and Usage For Vemlidy
- In adults, TAF is noninferior to TDF in its ability to control viral load over 48 to 96 weeks when used in combination with EVG, COBI, and FTC27-30; with FTC and RPV31; with DRV, COBI, and FTC32-34; and when TAF and FTC are administered in combination with other ARV drugs.35 In a switch study of adults who were virologically suppressed on a three-drug regimen that included …
Vemlidy Dosage and Administration
- The combination of EVG, COBI, FTC, and TAF has been shown to have similar efficacy when used in adults and two groups of children: those weighing ≥35 kg and aged ≥12 years40 and those weighing ≥25 kg and aged ≥6 years41 (see the Elvitegravir section for details). In a switch study, treatment with BIC/FTC/TAF resulted in viral load suppression at 48 weeks in 49 of 50 (9…
Dosage Forms and Strengths
- Virologic suppression in people who are taking TAF or TDF is most closely related to intracellular TFV‑DP concentrations. In adults, TAF generates peripheral blood mononuclear cell TFV-DP concentrations that are twofold22 to sevenfold higher than those generated with TDF, at clinically meaningful doses.18,21,27 Higher TFV-DP concentrations result in a stronger antiviral potency1…
Warnings and Precautions
- TAF causes bone toxicity less frequently than TDF.27-29,32-35,52,53 For example, in one study of 1,733 randomized adult participants with HIV, those treated with EVG/c/FTC/TAF had a smaller decrease in BMD at the spine (mean change −1.30% vs. −2.86%; P < 0.0001) and hip (−0.66% vs. −2.95%; P < 0.0001) at 48 weeks than those given EVG/c/FTC/TDF.27 These differences w…
