Aciclovir Safety During Pregnancy & Breastfeeding
Is Aciclovir Safe During Pregnancy?
Aciclovir has been extensively studied during pregnancy and is generally considered safe for both mother and baby. The medication is classified as pregnancy category B, indicating that animal studies have not shown harmful effects to the foetus. Large-scale human studies have not demonstrated increased birth defects or pregnancy complications when aciclovir is used appropriately.
Dosage Recommendations for Pregnant Women
Healthcare providers may prescribe aciclovir 400mg tablets for pregnant women experiencing severe cold sore outbreaks or recurrent herpes infections. The typical dosage ranges from 200mg to 400mg taken three to five times daily, depending on the severity of symptoms. Treatment duration usually spans 5-10 days. EverydayMeds stocks aciclovir 400mg tablets and 5% cream formulations, both available with valid prescriptions.
First Outbreak vs Recurrent Episodes
Primary herpes infections during pregnancy may require more aggressive treatment than recurrent episodes. First-time infections can be more severe and potentially pose greater risks to pregnancy outcomes. Recurrent cold sores are typically milder and may only require topical aciclovir cream. Your healthcare provider will assess whether oral aciclovir tablets or topical treatment is most appropriate for your specific situation.
Third Trimester Considerations
Women with a history of genital herpes may be prescribed suppressive aciclovir therapy during the final weeks of pregnancy to reduce the risk of active lesions during delivery. This preventive approach can help avoid the need for caesarean section due to active herpes lesions. Dosing typically involves 400mg twice daily from 36 weeks until delivery.
Alternative Treatment Options
EverydayMeds also stocks valaciclovir tablets, which may be prescribed as an alternative to aciclovir during pregnancy. Valaciclovir offers improved bioavailability, potentially allowing for less frequent dosing. However, aciclovir remains the first-line choice during pregnancy due to its extensive safety data. Topical treatments like aciclovir 5% cream provide localised action with minimal systemic absorption.
