It is recommended to take it after meals and swallow the tablet whole with warm water. Do not chew or crush the tablet.

Usage for special groups

Patients with renal insufficiency need to adjust the dose: if the creatinine clearance is 30-49mL/min, reduce the dose by 50%, and if the creatinine clearance is 10-29mL/min, reduce the dose by 75%. Hemodialysis patients should be administered the drug immediately after dialysis. Renal function and mental status should be closely monitored when taking medication in the elderly.

Handling of missed doses

If you find that you have missed a dose, you should take it as soon as possible. If it is close to the time of the next dose, skip this time. Do not double the dose to avoid increasing the risk of adverse reactions. It is recommended to set a medication reminder to help take medication on time.

Will valacyclovir hydrochloride tablets cause drug interactions

Interactions with kidney-related drugs

Combined use with probenecid may inhibit drug excretion and increase blood drug concentration. Concomitant use with nephrotoxic drugs (such as aminoglycoside antibiotics) may aggravate renal damage. Concomitant use with diuretics requires careful monitoring of renal function.

Interactions with other antiviral drugs

Combined use with antiviral drugs such as ganciclovir and cidofovir may increase the risk of nephrotoxicity. Combined use with zidovudine may increase adverse reactions such as fatigue and drowsiness.

Special Precautions

Combined use with theophylline drugs may increase neurotoxicity. Caution is required when coadministering with immunosuppressants. Before use, inform your doctor of all medications you are taking, including prescription and over-the-counter drugs.

During treatment, liver and kidney function, blood routine and other indicators should be reviewed regularly. It is recommended that patients with herpes zoster return for a follow-up visit 1 week after treatment is completed. Patients on long-term suppressive therapy should be reviewed every 3-6 months.
