About Acyclovir 400mg tablets

Acyclovir is an antiviral medicine. While Acyclovir is commonly prescribed in the form of an ointment, this medication can also be administered in the form of tablets, cream, or injection. Acyclovir is highly effective in treating herpes zoster by blocking the reproduction of viral DNA. However, Acyclovir does not affect human DNA. The body is known to absorb approximately 1/5 of a typical dose of Acyclovir, whereas the body normally excretes it within 3 hours after administration. In the presence of kidney failure, the excretion of Acyclovir may take up to 20 hours.

Acyclovir may be prescribed to treat the following conditions:

  • herpes simplex
  • infection of the genitourinary system
  • herpes zoster
  • Shingles
  • herpetic keratitis
  • Cold Sores

Acyclovir can also be prescribed for the prevention of herpes breakouts during periods where the human immune system is weakened via enhancement of immunity and protective capabilities of the body.

Taking Acyclovir to fight against herpes can significantly reduce the appearance of new rashes, reduces the size of lesions on skin, reduces the risk of possible complications, and stimulates the appearance of the crust.
When Acyclovir is taken to fight against herpes zoster this medication can have an analgesic effect.
When Acyclovir is taken to treat herpes the following recommendations should be considered:

  • recommended course is five days
  • dose frequency of tablets is five times throughout the day
  • when taken as a preventative measure, one tablet should be taken four times a day
  • children should take half the dose that is recommended for adults
  • when herpes appears on the lips, outbreak areas should be covered with ointment every 4 hours 5 times a day

When Acyclovir is taken to treat chickenpox the following recommendations should be considered:

  • the daily dose of tablets is divided into four time periods
  • doses are calculated based on the amount of medicinal product per 1 kg of a child’s body weight
  • the duration of a course of Acyclovir therapy via tablets is five days
  • if treating rashes with ointment at 5% strength, the pimples should be lubricated 5-6 times throughout the day
  • for adults with chickenpox, Acyclovir is prescribed more often than children

For herpes breakouts (i.e., pimples with a dull yellow liquid inside) resulting in lesions that are covered with crusts, Acyclovir really helps. However, if you do not have herpes, the use of Acyclovir ointment is useless. The antiviral agent in Acyclovir is active against some types of viral infection, whereas in other cases this medication should not be used.

A diagnosis confirming whether Acyclovir should be prescribed can be determined by a dermatologist. The doctor will prescribe the necessary dosage and frequency of admission. To get rid of rashes, Acyclovir prescribed a combination of tablets for ingestion and cream for external application at a 5% concentration can help. Before applying Acyclovir as an ointment gently wipe the intended area with a cleanser. Acyclovir should be applied to the outbreak areas every 3-4 hours.

Use of Acyclovir can be effective if it is used exactly as prescribed:

  • use cream, ointment, or tablets only as directed by a doctor. Unauthorized use of Acyclovir can cause negative reactions
  • prior to taking Acyclovir, be sure to take a blood test to determine levels of creatinine and urea
  • during pregnancy, antiviral drugs should only be used with permission of a doctor
  • adhere to recommended dosages and frequency of admission
  • prior to starting a course of Acyclovir therapy in children, body weight should be quantified. Otherwise, the doctor will not be able to determine the optimal dose
  • an effect of the active component contained in Acyclovir on the body of infants has not been studied. Therefore, Acyclovir should not be prescribed to infants
  • carefully use this antiviral agent when driving vehicles
  • in adults over 60 years of age the half-life is increased. Patients older than 60 years of age need to regularly take tests to monitor kidney function. Periodic blood testing is mandatory
  • in cases of genital herpes; sexual contact should be avoided. Acyclovir does not prevent infection of the sexual partner even in the absence of an outbreak of the disease

Taking Acyclovir is not recommended for individuals demonstrating intolerance to this medication.
While people demonstrate high limits of tolerability to Acyclovir, in rare cases complications can arise such as:

  • allergic reactions
  • diarrhea
  • fatigue
  • nausea
  • headache

Acyclovir for children

In cases of a modest outbreak, a doctor typically prescribes Acyclovir in ointment form to be applied to the problem areas
for severe viral infections, complex Acyclovir therapy involving both ointment and tablets is recommended.

Side effects associated with Acyclovir are most commonly caused by pills. Acyclovir, when administered as an ointment, is only modestly absorbed into blood and it has no harmful effects

Acyclovir dosing is individual specific. When prescribed to children, dosage determination takes into account body weight and the state of the immune system
200 mg tablets are prescribed for children from three years of age.
