How to ensure safe use of Amoxicillin and Zoloft?

If you have to take both these medicines together, consider these essential safety tips for a smoother experience.

Acidity-reducing medicines:

If you find yourself experiencing stomach discomfort while taking these medications together, it is worth discussing the possibility of using acidity-reducing medicines.

These medicines are commonly prescribed to relieve gastric pain and discomfort. some common classes are Proton pump inhibitors such as Omeprazole and over-the-counter antacids such as milk of magnesia, Gaviscon etc

Make sure to inform your pharmacist or doctor about your current medicine use including amoxicillin and sertraline to avoid interactions such as Sertraline with Bismuth subsalicylate (Pepto-bismol) may lead to serious bleeding.

Maintain a healthy diet:

To avoid gastrointestinal discomfort, aim to include healthy food groups in your diet. Opt for easy-to-digest foods that are gentle on your stomach and avoid spicy, junk foods.

Sertraline can interact with certain foods, so avoid alcohol, caffeine, tyramine-rich foods and grapefruit. Alcohol intake can worsen stomach discomfort and increase acidity. Caffeine in coffee, tea and certain sodas can irritate the stomach lining and exacerbate stomach pain and acidity.

Include probiotics

Yoghurt is a common source of probiotics. including yoghurt in your diet while taking Amoxicillin can reduce the chance of diarrhoea and stomach upset. Discuss with your healthcare provider which supplements or live cultures might be suitable for you.
