gonadotropin (beta-HCG) pregnancy tests performed within 21 days prior to the
start of the study and on the evening prior to each dose administration. If
dosing is scheduled on weekends, the HCG pregnancy test should be given within 48
hours prior to dosing of each study period. An additional serum (beta-HCG)
pregnancy test will be performed upon completion of the study.

2. Women of childbearing potential must practice abstinence or be using an
acceptable form of contraception throughout the duration of the study. No
hormonal contraceptives or hormone replacement therapy are permitted in this

1. intrauterine device in place for at least 3 months prior to the start of the
study and remaining in place during the study period, or

2. barrier methods containing or used in conjunction with a spermicidal agent,
or

3. surgical sterility (tubal ligation, oophorectomy or hysterectomy) or
postmenopausal accompanied with a documented postmenopausal course of at
least one year.

3. Women will not be considered of childbearing potential if one of the following is
reported and documented on the medical history:

1. postmenopausal with an absence of menses for at least one (1) year, or

2. bilateral oophorectomy with or without a hysterectomy and an absence of
bleeding for at least 6 months, or

3. total hysterectomy

4. During the course of the study, from study screen until study exit, all men and
women of childbearing potential must use a spermicide-containing barrier method
of contraception in addition to their current contraceptive device. This
requirement should be documented in the informed consent form.

3. Weight: At least 60 kg (132 lbs) for men and 48 kg (106 lbs) for women and all
subjects within 15% of Ideal Body Weight (IBW), as referenced by the Table of
"Desirable Weights of Adults" Metropolitan Life Insurance Company, 1999 (See Part II
ADMINISTRATIVE ASPECTS OF BIOEQUIVALENCE PROTOCOLS).

4. All subjects should be judged normal and healthy during a pre-study medical evaluation
(physical examination, laboratory evaluation, hepatitis B and hepatitis C tests, HIV
test, 12-lead ECG, and urine drug screen including amphetamine, barbiturates,
benzodiazepines, cannabinoid, cocaine, opiate screen, phencyclidine, and methadone)
performed within 21 days of the initial dose of study medication.

5. Abnormal and clinically significant laboratory test results:

1. Clinically significant deviation from the Guide to Clinically Relevant
Abnormalities (See Part II ADMINISTRATIVE ASPECTS OF BIOEQUIVALENCE PROTOCOLS).

2. Abnormal and clinically relevant ECG tracing.

6. Donation or loss of a significant volume of blood or plasma (> 450 mL) within 28 days
prior to the initial dose of study medication.

7. Subjects who have received an investigational drug within 30 days prior to the initial
dose of study medication.

8. Allergy or hypersensitivity to valacyclovir, acyclovir or any other related drugs.
