My child had chickenpox a few weeks ago when I was 8 weeks pregnant. I had a blood test done which confirmed that I haven’t had it yet so I am not immune. At that time I got prescribed acyclovir 800 mg tablets to take it for 7 days. After I finished the course we both went back to work which is a nursery. Again there was an outbreak of chickenpox. I am now 11 weeks pregnant and the doctor is prescribed me again the acyclovir 800 mg. Is it safe to take it this often during pregnancy? I am worried if it will cause anything to my baby.
