Hi Thanks for posting your query on HCM, I appreciate your concern for the chickenpox and your pregnant wife. If you have fever, take acetaminophen tablets every 8th hrly. For itching/scratching calamine lotion to be applied to the affected area or tablet levocetrizine is equally effective. Loose-fitting cotton clothes are the best and will help stop the skin from becoming sore and irritated. Drink plenty of water to avoid dehydration. Avoid hot spicy and salty food may make the mouth sore, soup is easy to swallow as long as it is not too hot or spicy. Antiviral drug Aciclovir needs to be started within 24 hours of the rash appearing. It does not cure chickenpox, but it makes the symptoms less severe. You may need to take these tablets five times a day for seven days. Since your wife is pregnant, she is having a high risk of develop severe chickenpox infection, so she should be given Varicella-zoster immunoglobulin (VZIG) injection to prevent the disease. Hope this answers your query. A feed back is appreciated.
