A nurse is caring for a client who has a chlamydial infection and a new prescription for doxycycline. The client reports nausea and vomiting after starting the medication. Which of the following recommendations should the nurse make?

A. Take the medication and then lay down for 30 min. Doxycycline can cause esophageal irritation and ulceration if not taken properly. Clients should remain upright for at least 30 minutes after taking the medication to reduce the risk of esophagitis. Lying down immediately after ingestion increases this risk. B. Take the medication with an antacid. Antacids containing aluminum, calcium, or magnesium can interfere with doxycycline absorption, reducing its effectiveness. Clients should avoid taking antacids within 1 to 2 hours of doxycycline administration. C. Take the medication with calcium-fortified orange juice. Calcium interferes with the absorption of doxycycline, potentially decreasing its effectiveness. Clients should avoid dairy products and calcium-rich foods or beverages when taking this medication. D. Take the medication with crackers. Taking doxycycline with food, such as crackers or a light snack, can help reduce gastrointestinal discomfort without significantly affecting its absorption. Although doxycycline is best absorbed on an empty stomach, taking it with a small amount of food can help minimize nausea and vomiting.
