Aciclovir

What is Aciclovir?

Aciclovir belongs to a group of antiviral medicines. It is commonly prescribed to treat and prevent a recurring attack of herpes, e.g. cold sores and genital herpes. It can also be used to protect those who suffer from low immune systems from contracting the herpes virus. Although it is not possible for a medication to cure the herpes virus, Aciclovir works to slow the growth and spreading of the virus around your body. As a result of this, it will lesson your symptoms of the infection.

Doctors may also prescribe Aciclovir to treat shingles and chicken pox as they are also caused by the herpes virus, varicella zoster. Depending on how you prefer to administer your medicine and what your ailment is, Aciclovir can be bought as a cream or tablet form. At Medicine Direct we sell the tablet form of Aciclovir in the dosage of 400mg.

Aciclovir can be used for a number of conditions, it is primarily used to treat the below:

Herpes Simplex Virus - To use Aciclovir to treat Genital Herpes you will either be instructed to take 200mg Aciclovir five times a day, between four hour intervals, for example at 7am, 11am, 3pm, 7pm and 11pm. It may have to be a prolonged course past the usual five days if your condition does not improve. Alternatively, you may be advised to take a stronger dose of 400mg.

Shingles - A doctor will instruct you to take Aciclovir for 7 days to treat shingles. This will be issued in 800mg dosages, five times a day within four hour intervals. For instance, following the pattern of 6am, 10am, 2pm, 6pm and 10pm.

Herpes Prophylactic treatment – If you are regularly suffering from Herpes breakouts your doctor or GP will advise you to take either 200mg four times a day or 400mg twice day to prevent a return of herpes. This is more common in individuals that suffer with a low immune system.
