Antibiotics vs. antifungals: Some antibiotics (such as erythromycin) are used concomitantly with antifungals (such as ketoconazole) and may increase plasma concentrations of the drug, leading to increased toxicity. Antipyretics and anticoagulants: Nonsteroidal anti-inflammatory drugs (such as ibuprofen) are used to reduce fever and may increase the risk of bleeding when taken with anticoagulants (such as warfarin). 
Multivitamin supplements: When taking multivitamin and mineral supplements at the same time, be aware of possible interactions, such as excess iron that can interfere with zinc absorption. Cough medicines and antidepressants: Some cough medicines contain antihistamines, which can be taken with specific antidepressants, such as monoamine oxidase inhibitors, and can lead to a severe*** such as high blood pressure crisis. Antibiotics and dairy products: For example, tetracycline antibiotics are taken at the same time as foods that are high in calcium, such as milk, which can reduce the efficiency of antibiotic absorption. 
*Loading....Anticoagulants and foods containing vitamin K: Anticoagulants (such as warfarin) taken with foods high in vitamin K (such as green leafy vegetables) can reduce the effectiveness of the drug because vitamin K is an important factor in blood clotting. Thyroid medications and soy products: Thyroid medications, such as levothyroxine, taken with soy products, may affect the absorption of the drug. Hypoglycemic drugs and sugary foods or alcohol: Hypoglycemic drugs, along with high intake of sugary foods or alcohol consumption, can lead to erratic glycemic control and even hypoglycemia.
