Relenza
Uses
of Relenza :
ZANAMIVIR
- ORAL INHALER
(zuh-NAM-uh-veer)
COMMON BRAND NAME(S):
Relenza
RELENZA USES:
This medication is used to treat illness (symptoms) caused
by the flu virus (influenza).
OTHER RELENZA USES:
Zanamivir may also be used to prevent the flu (e.g., in household
members exposed to a flu sufferer).
HOW TO USE RELENZA :
Inhale the medication through the mouth, generally 2 inhalations
twice daily (approximately 12 hours apart) for 5 days, or
as directed by your doctor. When possible, take two doses
(each dose is 2 inhalations) on the first day of treatment,
waiting at least two hours between doses.
Learn all usage instructions in the product
package and ask your doctor or pharmacist for advice if you
are unclear about any of the information.
Check the mouthpiece to be sure it is free
of foreign objects before use. Load the medication disk into
the diskhaler. Puncture one medication blister. Keep diskhaler
level so that medication will not spill. Breathe out through
the mouth, put the mouthpiece into your mouth and breathe
in deeply. Hold your breath for a few seconds so that the
medication will stay in your lungs. If you have been directed
to inhale a second time, advance to the next medication blister
and repeat the process. Once you have inhaled the number of
times prescribed, replace the cover of the diskhaler.
This medication works best when the amount
of medicine in your body is kept at a constant level. Take
the drug at evenly spaced intervals (e.g., every 12 hours).
Continue to take this medication until the
full prescribed amount is finished, even if symptoms improve.
Stopping the medication too early may allow the virus to continue
to grow, resulting in a relapse of the infection.
It is recommended that this medication be
used within 48 hours of the start of flu symptoms.
If you have breathing problems (asthma or
COPD) and are scheduled to use inhaled bronchodilators (e.g.,
albuterol) at the same time as zanamivir, use the asthma medication
before using zanamivir. Ask your doctor or pharmacist for
more details.
RELENZA SIDE EFFECTS:
Nausea, diarrhea or headache may occur. If any of these effects
persist or worsen, notify your doctor promptly.
Tell your doctor immediately if you have
any of these unlikely but serious side effects: cough, runny
nose, sore throat, fever, fatigue, muscle or joint pain, ear
pain.
An allergic reaction to this drug is unlikely,
but seek immediate medical attention if it occurs. Symptoms
of an allergic reaction include: rash, itching, swelling,
dizziness, trouble breathing.
If you notice other effects not listed above,
contact your doctor or pharmacist.
RELENZA PRECAUTIONS:
Tell your doctor your medical history, including: allergies,
lung or breathing problems (e.g., asthma, COPD), kidney problems.
Limit alcohol intake, as it may intensify
certain side effects of this medication (e.g., dizziness).
Use caution when performing tasks requiring alertness (e.g.,
driving).
This medication is not generally recommended
for treatment of flu if you have lung problems (e.g., asthma,
emphysema/COPD).
This medication can cause breathing problems
(e.g., bronchospasm), which in rare cases can be fatal. If
you have lung/breathing problems and are using this medication,
have a fast-acting inhaled bronchodilator (e.g., albuterol
inhaler) readily available. If you experience breathing problems,
stop using zanamivir and contact your doctor immediately.
