Synjardy (Generic Empagliflozin-Metformin): Complete Medication Guide
Key Takeaways
Synjardy combines two diabetes medications to help lower blood sugar in adults with type 2 diabetes.
It works by helping your kidneys remove extra sugar through urine and improving how your body uses insulin.
Common side effects include yeast infections, urinary tract infections, and mild digestive issues.
You'll need regular check-ups to monitor kidney function and blood sugar levels while taking this medication.
Discuss with your doctor whether Synjardy is the right choice for your diabetes management plan.
Synjardy (Generic Empagliflozin-Metformin) Overview
Synjardy is a combination medication that brings together two powerful diabetes fighters: empagliflozin and metformin. It's prescribed to help adults with type 2 diabetes keep their blood sugar levels in a healthy range. This medication doesn't cure diabetes, but it's a tool that can help manage the condition when diet and exercise alone aren't enough.
Empagliflozin is an SGLT2 inhibitor—which is a fancy way of saying it helps your kidneys remove extra sugar from your blood by letting it pass into your urine. Metformin is an older, well-proven medication that reduces the amount of glucose your liver makes and helps your body use insulin more effectively. When combined, these two medications work together to tackle blood sugar from different angles. The generic version works exactly the same way as the brand-name Synjardy but typically costs less. If you're exploring your diabetes management options to consider, discuss with your clinician about whether this combination is right for your health goals.

Side Effects
Most people tolerate Synjardy well, especially when starting at a low dose. Your body may need time to adjust to the medication, and side effects often improve as you continue treatment. Always report any concerning symptoms to your healthcare provider.
Common Side Effects
Yeast infections: Empagliflozin increases sugar in your urine, which creates an environment where yeast can grow. These infections are usually easy to treat.
Urinary tract infections (UTIs): Similar to yeast infections, the extra sugar in your urine may increase UTI risk. Drink plenty of water and practice good hygiene.
Nausea and stomach upset: Metformin can cause mild digestive discomfort, especially when you first start taking it or after meals.
Diarrhea or constipation: Changes in digestion are possible and may improve with time as your body adjusts.
Headache: Some people experience mild headaches, which usually go away after a few doses.
Dizziness: You may feel lightheaded, especially when standing up quickly, as your blood sugar levels change.
Serious Side Effects
Diabetic ketoacidosis (DKA): A rare but serious condition where your body produces too many acids. Symptoms include shortness of breath, unusual tiredness, stomach pain, or fruity-smelling breath.
Lactic acidosis: An extremely rare but serious buildup of lactic acid in your blood. Watch for muscle pain, difficulty breathing, or unusual tiredness.
Severe urinary tract infections: While mild UTIs are common, some infections can become serious and affect your kidneys.
Low blood sugar (hypoglycemia): If you're also taking insulin or other diabetes pills, your blood sugar may drop too low, causing shakiness, sweating, or confusion.
Acute kidney injury: Rare but possible, especially if you become dehydrated or have existing kidney problems.
When to Seek Medical Attention
Contact your doctor right away if you experience severe nausea, vomiting, or persistent diarrhea; shortness of breath or difficulty breathing; confusion or unusual tiredness; fruity-smelling breath; or signs of a serious infection like fever with pelvic pain or burning during urination.
Don't wait for your next scheduled appointment if you notice these warning signs. Call your healthcare provider or go to an urgent care clinic if symptoms feel urgent. If you're unsure whether something is serious, it's always better to check with a professional than to worry alone.

Important: Take Synjardy exactly as your doctor prescribed. Don't stop taking it without talking to your doctor first, even if you feel better. If you miss a dose, take it as soon as you remember unless it's almost time for your next dose. Never double up on doses. Missing doses can cause your blood sugar to rise and make diabetes harder to control.
Drug Interactions
Synjardy can interact with many other medications and substances. These interactions may change how well the medication works or increase your risk of side effects. Always tell your doctor and pharmacist about every medication, supplement, and herbal product you take.
Insulin and Other Blood Sugar Medications
Taking Synjardy with insulin, sulfonylureas, or meglitinides increases your risk of low blood sugar. Your doctor may need to lower the dose of these other medications when you start Synjardy.
ACE Inhibitors and ARBs (Blood Pressure Medications)
Drugs like lisinopril, enalapril, losartan, and valsartan combined with Synjardy may increase the risk of low blood sugar and kidney problems. Your kidney function and blood sugar will need closer monitoring.
Diuretics (Water Pills)
Loop diuretics like furosemide can increase the risk of dehydration and serious kidney problems when combined with Synjardy. Stay well-hydrated and have regular kidney check-ups.
Nonsteroidal Anti-inflammatory Drugs (NSAIDs)
Pain relievers like ibuprofen and naproxen can reduce kidney function and increase the risk of serious complications when used with Synjardy. Use the lowest dose for the shortest time possible.
Alcohol
Drinking alcohol, especially regularly or in large amounts, increases your risk of lactic acidosis—a serious side effect of metformin. It's best to limit alcohol or avoid it entirely while taking this medication.
Corticosteroids (Prednisone)
These anti-inflammatory medications can raise your blood sugar and work against Synjardy's effects. Your doctor may need to adjust your doses to keep your blood sugar stable.
