**Important Administration Instructions:** * **Give with a fatty meal:** This medication *must* be given with food high in fat (e.g., a small amount of ice cream, tuna oil, butter, or meat fat) to be properly absorbed into your pet's body. Without fat, the drug will not work effectively. * **Shake well:** Gently shake the bottle before drawing up each dose. * **Storage:** Store the liquid at room temperature, away from bright light. Do not freeze it. **What to Watch For:** * This medication is generally well-tolerated, but because it is a newer therapy in veterinary medicine, we are still learning about all potential side effects. * Contact your veterinarian immediately if your pet develops a skin rash, or experiences severe or persistent vomiting or diarrhea. * **Note:** The liquid is bright yellow and can stain fabrics or surfaces, so handle it carefully.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

It **must** be administered with a high-fat meal to ensure adequate systemic absorption. **Toxicity Warning:** Do not use the human combination product Malarone® (atovaquone and proguanil) in dogs due to severe gastrointestinal adverse effects associated with proguanil. **Pregnancy/Nursing:** FDA Category C.
