Medications can sometimes interact with each other in ways that change their effects. Some interactions are mild, while others can be life-threatening
What you need to know about common drug interactions and how to avoid them
ANTIBIOTICS + BIRTH CONTROL PILLS
Some antibiotics, can decrease the effectiveness of birth control pills. This interaction increases your risk of unintended pregnancy. Use backup contraception during antibiotic treatment.

Statins (e.g atorvastatin) lower cholesterol, but grapefruit juice can prevent them from leaving your body, leading to higher levels in your bloodstream. This can cause muscle damage or liver issues. Avoid grapefruit juice while on statins.
NSAIDS + BLOOD PRESSURE MEDICATIONS
Nonsteroidal anti-inflammatory drugs (NSAIDs), like ibuprofen, can reduce the effectiveness of blood pressure medications, leading to increased blood pressure. Limit NSAID use and talk to your doctor if you have hypertension.
BLOOD THINNERS + PAIN RELIEVERS
Using blood thinners (e.g., warfarin, aspirin) with NSAIDs (e.g., diclofenac) can increase the risk of bleeding. This interaction can lead to serious complications, such as gastrointestinal bleeding.
DIURETICS + ACE INHIBITORS
Diuretics (water pills like hydrochlorothiazide) and ACE inhibitors (lisinopril) are both used to treat high blood pressure
when taken together, they could lead to dangerously low blood pressure or high potassium levels. Always monitor your blood pressure when combining these.
BETA BLOCKERS + ASTHMA INHALERS
Beta-blockers (eg propanolol), used to manage blood pressure, can interfere with asthma medications (bronchodilators), worsening asthma symptoms. If you have both conditions, discuss alternative medications with your doctor.
ANTACIDS + ANTIBIOTICS
Some antacids containing aluminium or magnesium can reduce the absorption of certain antibiotics (e.g., tetracyclines or fluoroquinolones), making them less effective. Take antibiotics 2 hours before or 6 hours after taking antacids.
