Should Tamiflu Be Taken With Food? Yes, Tamiflu (oseltamivir), a medication prescribed to treat and prevent influenza A and B infections, is generally recommended to be taken with food. According to experts at FOODS.EDU.VN, this practice can significantly reduce the incidence and severity of gastrointestinal side effects such as nausea and vomiting. This article explores the reasons behind this recommendation, potential side effects, and how to manage them effectively, providing a thorough guide for anyone using Tamiflu. This will cover everything from the best ways to mitigate side effects to understanding the drug’s effectiveness.
1. Understanding Tamiflu and Its Purpose
Tamiflu, known generically as oseltamivir phosphate, is an antiviral medication primarily used to treat and prevent influenza A and B viruses. It functions by inhibiting the neuraminidase enzyme, which is crucial for the flu virus to spread from cell to cell within the body. This inhibition helps to reduce the severity and duration of flu symptoms.
- How Tamiflu Works: Oseltamivir targets the neuraminidase enzyme on the surface of the influenza virus. By blocking this enzyme, Tamiflu prevents the virus from budding off and infecting new cells.
- Primary Uses:
- Treatment: Tamiflu is used to treat the flu in individuals who are experiencing symptoms, ideally within the first 48 hours of symptom onset.
- Prevention: It is also used preventatively in individuals who have been exposed to the flu virus, such as during a flu outbreak.
- Target Population:
- Adults and children (as young as two weeks old for treatment and one year old for prevention).
- Individuals at high risk of flu complications (e.g., those with chronic medical conditions).
2. Why Take Tamiflu With Food?
Taking Tamiflu with food is primarily recommended to minimize gastrointestinal side effects. These side effects are among the most commonly reported by individuals taking the medication. By understanding the reasons behind this recommendation, patients can better manage their treatment and improve their overall experience.
- Reduced Nausea: Food can help to buffer the stomach lining, reducing the likelihood of nausea, a common side effect of Tamiflu.
- Minimized Vomiting: Similar to nausea, food can also decrease the incidence of vomiting by slowing the absorption rate of the drug.
- Enhanced Tolerability: Overall, taking Tamiflu with food makes the medication more tolerable, encouraging patients to complete their prescribed course.
3. Common Side Effects of Tamiflu
While Tamiflu is generally well-tolerated, it can cause side effects in some individuals. According to research, being aware of these potential side effects can help patients and caregivers recognize and manage them effectively.
- Gastrointestinal Issues:
- Nausea: As noted, this is one of the most frequently reported side effects.
- Vomiting: Often accompanies nausea, particularly if the medication is taken on an empty stomach.
- Stomach Pain: Some individuals may experience abdominal discomfort.
- Diarrhea: Though less common, diarrhea can also occur.
- Neurological Effects:
- Headache: A common side effect experienced by many users.
- Insomnia: Some patients report difficulty sleeping while taking Tamiflu.
- Dizziness: Feeling lightheaded or dizzy is possible.
- Other Side Effects:
- Fatigue: General tiredness or lack of energy.
- Nosebleeds: Less common, but reported in some cases.
- Diaper Rash: Specifically observed in infants.
4. Serious Side Effects and Warnings
While most side effects of Tamiflu are mild, some serious side effects and warnings must be taken into consideration. According to the FDA, being vigilant about these can help prevent severe complications.
- Neuropsychiatric Effects:
- Abnormal Behavior: Especially in children, Tamiflu has been associated with changes in behavior.
- Delirium: Confusion and disorientation can occur.
- Hallucinations: Seeing or hearing things that are not there.

- Take With Food: Always administer Tamiflu with a meal or snack to reduce gastrointestinal distress.
- Stay Hydrated: Drink plenty of fluids to combat dehydration, especially if experiencing vomiting or diarrhea.
- Monitor for Behavioral Changes: Especially in children, carefully monitor for any unusual behavior or psychiatric symptoms.
- Prompt Medical Attention: Seek immediate medical attention if severe allergic reactions or neuropsychiatric symptoms occur.
- Adjust Dosage: For individuals with kidney problems, a lower dose of Tamiflu may be necessary.
6. Tamiflu Dosage and Administration
Proper dosage and administration of Tamiflu are crucial for its effectiveness and to minimize side effects. The recommended dosage varies depending on the individual’s age, weight, and kidney function.
- Standard Dosage:
- Adults and Adolescents (13 years and older): 75 mg twice daily for five days for treatment.
- Children (1 to 12 years): Dosage varies by weight.

7. Food Choices to Help Reduce Side Effects
Selecting the right foods can significantly reduce the likelihood and severity of gastrointestinal side effects. The following food choices are recommended by nutrition experts at FOODS.EDU.VN:
- Bland Foods:
- Toast: Easy to digest and can help settle the stomach.
- Crackers: Saltines are a good option for relieving nausea.
- Rice: Plain, cooked rice is gentle on the digestive system.
- Bananas: Provide essential nutrients and are easy to digest.
