Prescription Product: We will ask for your prescription information after checkout.
Before taking oseltamivir:
- tell your doctor and pharmacist if you are allergic to oseltamivir, any other medications, or any of the ingredients in oseltamivir capsules or suspension. Ask your pharmacist or check the manufacturer's patient information for a list of the ingredients.
- tell your doctor what prescription and nonprescription medications, vitamins, nutritional supplements and herbal products you are taking or plan to take. Be sure to mention any of the following: medications that affect the immune system such as azathioprine (Imuran); cyclosporine (Neoral, Sandimmune); cancer chemotherapy medications; methotrexate (Rheumatrex); sirolimus (Rapamune); oral steroids such as dexamethasone (Decadron, Dexone), methylprednisolone (Medrol), and prednisone (Deltasone); or tacrolimus (Prograf). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have ever taken oseltamivir to treat or prevent the flu.
- tell your doctor if you have any disease or condition that affects your immune system such as human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) or if you have heart, lung, or kidney disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking oseltamivir, call your doctor.
- you should know that people, especially children and teenagers, who have the flu may become confused, agitated, or anxious, and may behave strangely, have seizures or hallucinate (see things or hear voices that do not exist), or harm or kill themselves. You or your child may develop these symptoms whether or not you or your child uses oseltamivir, and the symptoms may begin shortly after starting treatment if you do use the medication. If your child has the flu, you should watch his or her behavior very carefully and call the doctor right away if he or she becomes confused or behaves abnormally. If you have the flu, you, your family, or your caregiver should call the doctor right away if you become confused, behave abnormally, or think about harming yourself. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.
- ask your doctor if you should receive a flu vaccination each year. Oseltamivir does not take the place of a yearly flu vaccine. If you received or plan to receive the intranasal flu vaccine (FluMist; flu vaccine that is sprayed into the nose), you should tell your doctor before taking oseltamivir. Oseltamivir may make the intranasal flu vaccine less effective if it is taken up to 2 weeks after or up to 48 hours before the intranasal flu vaccine is given.
- if you have fructose intolerance (an inherited condition in which the body lacks the protein needed to break down fructose, a fruit sugar, such as sorbitol), you should know that the oseltamivir suspension is sweetened with sorbitol. Tell your doctor if you have fructose intolerance.
If you forget to take a dose, take it as soon as you remember it. If it is no longer than 2 hours before your next scheduled dose, skip the missed dose and continue your regular dosing schedule. If you miss several doses, call your doctor for directions. Do not take a double dose to make up for a missed one.
Oseltamivir may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- stomach pain
Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately:
- rash, hives, or blisters on the skin
- mouth sores
- swelling of the face or tongue
- difficulty breathing or swallowing
- speech problems
- shaky movements
- hallucinations (seeing things or hearing voices that do not exist)
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online http://www.fda.gov/Safety/MedWatch or by phone 1-800-332-1088.
Keep this medication in the container it came in and out of reach of children. Store the capsules at room temperature and away from excess heat and moisture (not in the bathroom). Commercial oseltamivir suspension can be kept at room temperature for up to 10 days or in the refrigerator for up to 17 days. Oseltamivir suspension prepared by a pharmacist can be kept at room temperature for up to 5 days or in the refrigerator for up to 35 days. Do not freeze oseltamivir suspension.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website http://goo.gl/c4Rm4p for more information if you do not have access to a take-back program.
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Symptoms of overdose may include:
Oseltamivir will not stop you from giving the flu to others. You should wash your hands frequently, and avoid practices such as sharing cups and utensils that can spread the virus to others.
Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of the flu after you finish taking oseltamivir, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
