Based on FDA | Is it safe to take sertraline with milk, or does dairy affect its absorption or effectiveness?

It is generally safe to take sertraline with milk, and dairy does not appear to meaningfully reduce its absorption or effectiveness. Standard guidance allows you to continue your normal diet while taking sertraline, and there is no routine restriction on dairy. ^[1] Sertraline tablets and liquid can be taken with or without food, and official patient instructions do not list milk or calcium foods as a problem. ^{[2] [1]}

What official guidance says

• Dietary restrictions: Consumer medication instructions state, “Unless your doctor tells you otherwise, continue your normal diet” when taking sertraline. ^[1] This implies no specific avoidance of milk or dairy is needed. ^[1]
• How to take it: Sertraline is typically taken once daily at the same time each day; there is no requirement to separate it from meals. ^[2] Many people take it with food if they have stomach upset, and dairy can be part of that meal. ^[2]

Food and absorption

• Food effect: Sertraline is absorbed slowly after oral dosing, with peak levels around 6–8 hours, and is suitable for once‑daily dosing. Clinical pharmacology reviews do not identify a clinically meaningful reduction in exposure with typical meals. ^[3] Because the label and patient instructions do not warn against milk or calcium, routine consumption of dairy is considered acceptable. ^[1]
• Liquid concentrate exception: If you use the sertraline oral concentrate, it should be mixed only with water, ginger ale, lemon‑lime soda, lemonade, or orange juice not milk or other unlisted liquids. ^[4] This is a preparation instruction for proper dilution of the concentrate, not a general prohibition on drinking milk near the dose. ^[4]

Calcium and drug interactions

• No known chelation issue: Some drugs (for example, certain antibiotics) bind with calcium and have reduced absorption; sertraline is not in this category and major references do not list a calcium/dairy interaction that reduces sertraline’s effectiveness. ^[1] Interaction cautions for sertraline focus on other medicines and supplements like St. John’s wort, tryptophan, NSAIDs, and certain serotonergic drugs, not dairy. ^[5]

Practical tips for taking sertraline

• Consistency matters: Take sertraline at the same time each day, with or without food, as you prefer. If you have nausea, taking it with a snack milk or yogurt included may feel gentler on the stomach. ^[2]
• Stick to approved mixers for the liquid: If you’re on the oral concentrate, only mix it with the specified beverages and drink it right away; do not use milk for mixing. ^[4]

Bottom line

For sertraline tablets or capsules, milk and dairy are generally fine and are not expected to reduce absorption or effectiveness. ^{[2] [1]} If you use the oral concentrate, do not dilute it with milk; use only the listed beverages. ^[4]
