Levofloxacin Diet Plan: What Foods To Avoid, Alcohol, Coffee

Levofloxacin is a prescription antibiotic for treating bacterial infections.

While taking Levofloxacin, you may wish to make certain changes to your diet in order to avoid interactions, reduce side effects, and ensure the optimum effectiveness of this medication.

Keep reading to learn what foods should be avoided when taking Levofloxacin, if it’s OK to drink coffee on Levaquin, and if taking Levofloxacin and alcohol together is safe.

What Foods Should Be Avoided When Taking Levofloxacin?

Dairy products

Some studies suggest that dairy products, such as milk and yogurt, may potentially interfere with levofloxacin’s action.

This is possibly due to the high amount of calcium present in them. 

Calcium can lower the levels of levofloxacin in the body and reduce its effectiveness. In addition, calcium can also bind with this antibiotic, preventing it from acting correctly.

Hence, it is advisable to avoid dairy products or consume them at least 2 hours before or after taking Quixin.

Fruit juices containing calcium

There is some evidence suggesting that fruit juices containing calcium may impact the effectiveness of levofloxacin.

Fruit juices that contain calcium or are fortified with calcium should be avoided while using levofloxacin, as calcium tends to reduce the Iquix levels in the body and lower its effectiveness.

You may consume these products 2 hours before or after taking the medication.

What to Eat with Levaquin?

It’s advisable to maintain a generally healthy and balanced diet while using levofloxacin.

Make sure you consume foods rich in immunity-boosting nutrients such as vitamin C and omega-3 fatty acids.

For example:

  • Citrus fruits
  • Strawberries
  • Bell peppers
  • Ginger
  • Garlic
  • Oily fish

For optimal effectiveness, it is recommended to take this medication with a full glass of water. 

Your healthcare provider may advise taking levofloxacin tablets on an empty stomach or with meals based on your specific health condition.

However, if you suffer from gastritis and are using antacids, take the doses about 2 hours after a meal. 

Is It Safe To Consume Levofloxacin and Alcohol Together?
