Summarize with: ChatGPT Perplexity Claude Google AI Grok

Deriphyllin Injection is a prescription medicine used to help improve breathing in some people with respiratory conditions. It contains etofylline and theophylline, which are bronchodilators. They help relax the muscles around the airways and make it easier for air to move in and out of the lungs.

This medicine is given by a doctor or nurse. The dose depends on the patient's age, condition, other medicines and response to treatment.

What is Deriphyllin Injection?

Deriphyllin Injection contains two bronchodilators, etofylline and theophylline. It may be used in some patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD).

The medicine works by relaxing the muscles in the airways. This can help widen the air passages and improve airflow.

Deriphyllin Injection is not usually the first choice for a sudden asthma attack. Current asthma guidelines do not recommend intravenous theophylline for routine treatment of acute asthma attacks because the benefit is limited and the risk of side effects can be significant.

Composition of Deriphyllin Injection

Deriphyllin Injection contains:

A commonly available Deriphyllin Injection contains etofylline 84.7 mg and theophylline 25.3 mg in 2 mL. Always check the strength on the product label because formulations may vary.

Indications for Deriphyllin Injection

Deriphyllin Injection may be prescribed for respiratory conditions that involve airway narrowing or bronchospasm, such as:

The decision to use an injectable form depends on the patient's condition and the doctor's assessment.

Uses of Deriphyllin Injection

Deriphyllin Injection may help ease breathing problems caused by narrowing of the airways.

How Does Deriphyllin Injection Work?

Etofylline and theophylline help relax the smooth muscles surrounding the airways. When these muscles relax, the airways can become wider. This allows air to pass more easily and may reduce breathing difficulty.

Deriphyllin Injection Dosage

There is no single dose that is suitable for everyone. The doctor decides the dose based on the patient's age, body weight, medical condition, previous theophylline use and response to treatment.

Theophylline has a narrow safety range. In some patients, blood tests may be needed to check the amount of theophylline in the blood and prevent toxicity.

For Adults

The adult dose is decided by the doctor based on the patient's condition and individual risk factors.

The dose may need to be adjusted if the patient has liver disease, heart problems, takes certain medicines or has previously been using theophylline.

Do not take or receive an extra dose unless it has been prescribed.

For Children

Children need an individualized dose based on their age, body weight, medical condition, and response to treatment.

Theophylline levels can vary considerably in children, so medical supervision is important. A fixed dose should not be given to a child without a doctor's advice.

Contraindications of Deriphyllin Injection

Deriphyllin Injection should not be used in people who are allergic to theophylline, etofylline, or any other ingredient in the injection.

Extra care may be needed if the patient has:

Tell your doctor about any existing medical conditions before receiving the injection.

Precautions and Warnings

Monitoring Theophylline Levels

Theophylline can build up in the blood if the dose is too high or if the body is unable to clear it properly. For this reason, the doctor may recommend blood tests in some patients.

Monitoring may be especially important when the dose is changed, when treatment is started in high-risk patients, or when symptoms of toxicity appear.

Drug Interactions

Several medicines can change the amount of theophylline in the blood. These include some antibiotics, anticonvulsants, and medicines used for other medical conditions.

Examples include ciprofloxacin, clarithromycin, erythromycin, cimetidine, carbamazepine, phenytoin and rifampicin.

This is not a complete list. Tell your doctor about all prescription medicines, over-the-counter medicines, vitamins and supplements you take.

Pregnancy and Breastfeeding

If you are pregnant, planning to become pregnant, or breastfeeding, talk to your doctor before using Deriphyllin Injection.

Theophylline can cross the placenta and can also pass into breast milk. Your doctor will consider the possible benefits and risks before recommending treatment.

Heart, Liver and Other Health Problems

Tell your doctor if you have heart disease, an irregular heartbeat, liver problems, seizures or other long-term health conditions. These conditions can affect how your body handles theophylline and may require closer monitoring.

Side Effects of Deriphyllin Injection

Some people may experience side effects while using Deriphyllin Injection. Common ones include:

These effects may become more noticeable if theophylline levels in the blood become too high.

Serious Side Effects

High levels of theophylline can sometimes cause serious problems, including:

Get immediate medical help if you develop a seizure, fainting, severe palpitations or signs of a serious allergic reaction.

Conclusion

Deriphyllin Injection contains etofylline and theophylline, which help relax the muscles around the airways. It may be used in selected patients with conditions such as asthma and COPD.

Theophylline needs careful dosing because too much of it can cause serious side effects. The dose should therefore be decided by a doctor, and some patients may need blood tests during treatment.

Deriphyllin Injection should be given only under medical supervision. Always inform your doctor about your existing health conditions and any medicines you are taking before treatment.
