Safety Guidelines for Pregnant and Breastfeeding Women

MHRA Position on Aciclovir in Pregnancy

The Medicines and Healthcare products Regulatory Agency (MHRA) classifies aciclovir as generally safe for use during pregnancy when the clinical benefits outweigh potential risks. Extensive pregnancy data shows no increased risk of birth defects when aciclovir is used appropriately.

Aciclovir Tablets During Pregnancy

Aciclovir 400mg tablets may be prescribed during pregnancy for cold sore outbreaks. Healthcare providers typically recommend treatment when symptoms are severe or frequent. The standard pregnancy dosing remains 400mg taken three times daily for 5 days, though your doctor may adjust this based on individual circumstances.

Topical Aciclovir Cream in Pregnancy

Aciclovir 5% cream is often preferred during pregnancy as minimal amounts are absorbed systemically. This topical treatment can effectively manage cold sores while minimising any theoretical risks. Apply the cream five times daily at the first signs of tingling or blister formation.

Safety During Breastfeeding

Aciclovir passes into breast milk in small amounts, but is considered compatible with breastfeeding. The amount an infant would receive through breast milk is significantly lower than paediatric treatment doses. Both oral tablets and topical cream may be used while breastfeeding under medical supervision.

When to Seek Medical Advice

Pregnant women should consult healthcare providers before starting aciclovir treatment. This is particularly important for first-time cold sore outbreaks during pregnancy, severe symptoms, or if you have frequent recurrent episodes. Your doctor can assess whether treatment is appropriate for your specific situation.

Available Treatment Options

EverydayMeds offers aciclovir tablets and topical treatments that may be suitable during pregnancy when prescribed by healthcare providers. Treatment options include aciclovir 400mg tablets for oral therapy and aciclovir 5% cream for topical application, both available through our regulated online pharmacy service.
