Why is this medication prescribed?

DNase (Deoxyribonuclease) is an enzyme that breaks down DNA. It is often prescribed in medical settings for various reasons, primarily to reduce the viscosity of respiratory secretions in patients with cystic fibrosis, chronic obstructive pulmonary disease (COPD), or other conditions characterized by thick mucus buildup in the airways. By breaking down the DNA present in the mucus, DNase helps to thin it out, making it easier for patients to cough up and clear from their airways.

How should this medicine be used?

DNase is typically administered through inhalation to help break down the thick mucus in the lungs, making it easier to clear and improving breathing. It can be inhaled using a nebulizer or through a special inhaler device.

The specific dosage and frequency of DNase administration will depend on the individual’s condition and the doctor’s prescription. It’s essential to follow the instructions provided by the healthcare provider or pharmacist carefully. Typically, DNase is used once or twice daily, but this can vary based on the severity of the condition and the individual’s response to treatment.

If you or someone you know has been prescribed DNase, it’s essential to consult with a healthcare professional for detailed instructions on how to use it properly and safely.

Other uses for this medicine

As for other uses of DNase, it’s primarily prescribed for conditions where excessive DNA accumulation leads to mucus obstruction in the lungs, such as cystic fibrosis. However, there is ongoing research into its potential use in other conditions where thick mucus plays a role in disease pathology, such as chronic obstructive pulmonary disease (COPD) and bronchiectasis. These uses are not yet widely established and would require further clinical studies to determine efficacy and safety.

What special precautions should I follow?

Regarding special precautions for DNase use:

• Allergies: Inform your healthcare provider if you have any allergies, especially to proteins or any other components of DNase. Allergic reactions, though rare, can occur.
• Respiratory Function: DNase is typically used in patients with compromised respiratory function. If you experience any worsening of respiratory symptoms or difficulty breathing after using DNase, seek medical attention immediately.
• Drug Interactions: Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as they may interact with DNase.
• Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of DNase with your healthcare provider before using it.
• Storage and Handling: Store DNase according to the manufacturer’s instructions, and ensure that it is kept out of reach of children.

Always follow your healthcare provider’s instructions and guidelines for the safe and effective use of DNase. If you have any concerns or questions about its use, don’t hesitate to consult your healthcare provider or pharmacist.

What special dietary instructions should I follow?

Regarding special dietary instructions for DNase, there are typically no specific dietary restrictions associated with its use. However, it’s essential to maintain a balanced diet and stay hydrated, especially if you have a respiratory condition like cystic fibrosis. Drinking plenty of fluids can help thin mucus and make it easier to clear from your airways.

What should I do if I forget a dose?

If you forget a dose of DNase, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one. If you have any concerns or questions about missed doses, consult your healthcare provider or pharmacist for guidance.

What side effects can this medication cause?

Dornase alfa (DNase) is generally well-tolerated, but like any medication, it can cause side effects in some individuals. Common side effects associated with DNase use may include:

• Cough: DNase can sometimes cause or worsen coughing, which is typically temporary and mild.
• Voice Hoarseness: Some individuals may experience hoarseness or changes in voice quality after using DNase.
• Sore Throat: Irritation or soreness in the throat may occur in some cases.
• Nasal Congestion or Runny Nose: DNase use may lead to nasal congestion or a runny nose in some individuals.
• Nasal Sinusitis: Inflammation of the nasal sinuses can occur rarely as a side effect of DNase use.
• Rash or Skin Irritation: Skin reactions such as rash or irritation at the site of contact with DNase may occur.
• Eye Irritation: Some individuals may experience eye irritation or redness if DNase comes into contact with the eyes.
• Respiratory Symptoms: In rare cases, DNase use may lead to worsening of respiratory symptoms, including difficulty breathing or wheezing.

It’s important to note that not everyone will experience these side effects, and many people tolerate DNase well with minimal or no adverse effects. If you experience any persistent or severe side effects while using DNase, it’s essential to notify your healthcare provider. They can provide guidance on managing side effects or adjust your treatment regimen if necessary.

Additionally, this list may not include all possible side effects of DNase. If you have concerns about potential side effects or notice any unusual symptoms while using DNase, consult your healthcare provider for further evaluation and advice.

What should I know about storage and disposal of this medication?

Storage and disposal guidelines for DNase (dornase alfa) typically include the following:

• Storage: Store DNase according to the manufacturer’s instructions, typically at room temperature (around 20-25°C or 68-77°F). Avoid exposure to excessive heat, light, or moisture. Do not freeze DNase. Keep it in its original packaging or container, away from children and pets.
• Disposal: Dispose of DNase and its packaging according to local regulations or guidelines. Do not flush DNase down the toilet or pour it down the drain unless instructed to do so. If you have unused or expired DNase, consult your healthcare provider, pharmacist, or local waste disposal authority for proper disposal instructions.

In case of emergency/overdose

• Contact Emergency Services: If someone has taken an overdose of DNase or is experiencing severe adverse reactions, call emergency services (such as 911 in the United States) immediately for medical assistance.
• Seek Medical Attention: If you or someone else has taken more DNase than prescribed or is experiencing symptoms of overdose, seek medical attention promptly. Be prepared to provide information about the amount of DNase taken, when it was taken, and any symptoms experienced.
• Follow Medical Advice: Follow any instructions provided by healthcare professionals or emergency responders. Treatment for DNase overdose will depend on the severity of symptoms and may include supportive care and monitoring.
