Description

Indications

Theophylline is prescribed for the treatment of respiratory conditions such as asthma and COPD, including bronchitis and emphysema. Consistent use of this medication is essential to prevent wheezing and breathlessness. Classified under the category of xanthines, it operates by relaxing the muscles surrounding the air passages, facilitating their dilation and thereby promoting easier breathing.

Uses and Dosage

Follow your doctor’s guidance when taking this medication by mouth, typically once or twice a day.

Avoid crushing or chewing the capsules or tablets, as this can lead to the rapid release of the entire drug, increasing the risk of side effects. Do not split tablets unless they have a score line, and your doctor or pharmacist advises you to do so. Swallow the tablet whole or, if instructed, split it without crushing or chewing.

The dosage is determined based on your medical condition, how you respond to treatment, your age, weight, the results of lab tests (theophylline blood levels), and any other medications you may be using. Ensure you inform your doctor and pharmacist about all the products you are taking, including prescription drugs, nonprescription drugs, and herbal supplements. To minimize the risk of side effects, your doctor may recommend starting with a low dose and gradually increasing it. Adhere closely to your doctor’s instructions.

It’s worth noting that certain diets, such as those high in protein/low in carbohydrates or high in carbohydrates/low in protein, can affect the way theophylline works. Notify your doctor if you make significant changes to your diet, as your medication dose may need adjustment.

Take this medication consistently. To help you remember, take it at the same time(s) daily. Continue taking the medication even if you feel well. Do not alter your dose, increase its frequency, or discontinue it without consulting your doctor first.

Seek immediate medical assistance if your asthma symptoms worsen, or if you find yourself using your quick-relief inhaler more frequently than usual or beyond the prescribed dosage.

Caution

Prior to starting theophylline, inform your doctor or pharmacist if you have any allergies, particularly if you are allergic to theophylline itself, other xanthine drugs like aminophylline, oxtriphylline, or caffeine, or if you have any other allergies. This medication may contain inactive components that can trigger allergic reactions or other complications.

Before initiating this treatment, provide your doctor or pharmacist with your medical history, particularly if you have a history of stomach or intestinal ulcers, seizures, thyroid disorders, heart problems, liver disease, or high blood pressure.

If you fall ill or develop a fever while taking this medication, promptly inform your doctor. It may be necessary to adjust your medication dosage.

Older adults may be more susceptible to the side effects of this drug, particularly rapid or irregular heartbeats, or difficulties sleeping. Therefore, careful monitoring of side effects and drug blood levels is recommended.

Children may also be more sensitive to the side effects of this medication. It is advisable to closely monitor side effects and drug blood levels in pediatric patients.

During pregnancy, use this medication only when it is clearly necessary. Discuss the potential risks and benefits with your doctor. Changes in your body during the last three months of pregnancy may affect the levels of this drug in your bloodstream. Your doctor should monitor your drug levels and any associated side effects diligently to make any necessary dosage adjustments.
