Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving peramivir, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using peramivir with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other Medical Problems
The presence of other medical problems may affect the use of peramivir. Make sure you tell your doctor if you have any other medical problems, especially:
- Kidney disease—Use with caution. The effects may be increased because of slower removal of the medicine from the body.
Proper Use of This Medicine
A nurse or other trained health professional will give you peramivir in a hospital. It is given through a needle placed into one of your veins. The medicine must be injected slowly, so your IV tube will need to stay in place for 15 to 30 minutes.
Peramivir should be given as soon as possible after flu symptoms start or after you are exposed to the flu (within the first 2 days).
Precautions While Using This Medicine
Your doctor will check your or your child's progress closely while you are receiving peramivir. This is to make sure that the infection is cleared up completely.
Serious skin reactions can occur with peramivir. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, red skin lesions, severe acne or skin rash, sores or ulcers on the skin, or fever or chills while you are receiving peramivir.
Peramivir may cause some people to be confused or display other abnormal behaviors. Tell your doctor right away if you have hallucinations (seeing, hearing, or feeling things that are not there) or unusual excitement, nervousness, or restlessness after receiving peramivir.
Make sure your doctor knows if you plan to get the live flu vaccine nasal spray before you start receiving peramivir. You should not use the vaccine within 2 weeks before or 48 hours after receiving peramivir.
If your symptoms do not improve after you receive peramivir, or if they become worse, check with your doctor.
