If you are using this medication, speak with your doctor or pharmacist for information about your treatment options.
How should I use this medication?
This medication is used in a nebulizer. Treatment is usually started in a hospital setting. The usual adult dose (for those 12 years and over) is 4 mL (one unit dose vial) of ipratropium - fenoterol solution inhaled via a nebulizer. Treatment may be repeated after 6 hours if necessary. If less than 4 mL of solution is to be used at one time as prescribed by your doctor, use a syringe to transfer the necessary amount to the nebulizer chamber. Discard any solution left in the plastic vial, as the solution does not contain preservatives.
If less than 2 mL of solution is to be nebulized, a sterile, preservative-free saline or another suitable nebulizer solution should be used to make up the total volume to between 2 mL and 5 mL. Follow the instructions found with the medication and with your nebulizer for proper treatment, care, maintenance, and equipment cleaning procedures. It is very important to adjust the face mask, if required, to prevent the mist from getting into your eyes.
If this medication does not relieve your symptoms within 10 minutes after the nebulization is finished, if the dosage of medication does not provide relief for longer than 3 hours, or if you experience a worsening of your symptoms, contact your doctor or go to the nearest hospital, as these are signs that your condition may be worsening and that you need to be reassessed by a doctor.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Additional treatment: Like other inhalation solutions that contain beta agonists, ipatropium - fenoterol solution should not be used on a regular basis for the treatment of asthma without using appropriate inhaled anti-inflammatory medication (such as budesonide or fluticasone) at the same time.
Cystic fibrosis: People with cystic fibrosis may be more likely to have stomach discomfort (due to changes in how quickly food moves through the stomach and intestines) while using this medication.
Diabetes: Ipratropium - fenoterol solution may cause a loss of blood glucose control, and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication. If you have diabetes or are at risk for developing diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Eye concerns: Take care to ensure that the nebulizer mask fits your face properly and that nebulized solution does not escape into the eyes. If you have glaucoma or narrow anterior chambers, avoid using a combined ipratropium and beta-2-agonist solution by nebulizer unless you take measures (e.g., use of swimming goggles or use of a nebulizer with a mouthpiece) to ensure that nebulized solution does not reach the eye. There have been reports of eye complications (e.g., mydriasis, increased eye pressure, angle-closure glaucoma) when nebulized ipratropium, either alone or in combination with an adrenergic beta-2-agonist solution, comes into contact with the eyes.
Heart conditions: This medication can cause increased heart rate and blood pressure, making certain heart conditions worse. If you have heart disease, high blood pressure, irregular heart beat, heart failure, or have had a recent heart attack, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pheochromocytoma: If you have been diagnosed with pheochromocytoma (a tumour of the adrenal gland), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Potassium levels: Decreases in blood levels of potassium may occur with the use of this medication. This rarely causes problems, but potassium levels should be monitored by your doctor. If you experience unexplained muscle cramps, weakness, fatigue, or constipation, contact your doctor.
Urinary tract problems: Ipratropium - fenoterol solution can cause difficulty with starting the flow of urine. If you have an enlarged prostate or bladder retention, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Worsening of symptoms: Some people who receive inhaled beta-agonists have developed severe worsening of breathing. The cause of this is unknown. If it occurs, stop using this medication immediately and talk to your doctor about an alternative therapy as soon as possible.
Pregnancy: The safety of this medication for use while pregnant has not been established. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if ipratropium - fenoterol solution passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: Ipratropium - fenoterol is not currently recommended for use by children under 12 years of age, as its safety and dosing regimen for this age group have not been established.
