Taking or using aciclovir with other medicines and herbal supplements - Brand names: Zovirax, Cymex Ultra, Virasorb

Cautions with other medicines

Some medicines can affect the way aciclovir tablets or liquid work. They can also make you more likely to get side effects.

If you're using aciclovir cream on your skin, this is less likely to react with other medicines.

Tell your doctor if you take any of the following medicines before taking aciclovir:

  • cimetidine, a medicine for stomach ulcers
  • mycophenolate mofetil, a medicine given after organ transplants
  • probenecid, a medicine for gout
  • aminophylline or theophylline, medicines for asthma

Mixing aciclovir with herbal remedies and supplements

There's not enough information to say that herbal remedies or supplements are safe to take with aciclovir. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

Important: Medicine safety

Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
