Theophylline ER Tablet

Detail Description

Theophylline is a bronchodilator that is used to treat symptoms of asthma, bronchitis, emphysema, and other breathing problems.

Theophylline may also be used for purposes not listed in this medication guide.

Warnings

Never use theophylline in larger amounts, or for longer than prescribed. Seek medical attention if your breathing problems get worse quickly, or if you think your medications are not working as well.

Overdose can occur if you take too much theophylline at one time, or if your daily doses are too high.

Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact with theophylline.

Before taking this medicine

You should not use theophylline if you are allergic to it.

Tell your doctor if you have ever had:

  • a gastric or peptic ulcer;

  • a serious infection called sepsis;

  • liver disease (especially cirrhosis or hepatitis);

  • fluid in your lungs;

  • heart problems;

  • a thyroid disorder;

  • seizures; or

  • kidney disease.

Tell your doctor if you drink alcohol, or if you smoke or have recently quit smoking cigarettes or marijuana.

Also tell your doctor if you have been sick with a high fever (102 degrees or higher) for 24 hours or longer.

Tell your doctor if you are pregnant or breastfeeding.

 

Do not give theophylline to a child without medical advice.

How should I take theophylline?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Never use theophylline in larger amounts, or for longer than prescribed.

Theophylline is not a rescue medicine for asthma or bronchospasm attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your breathing problems get worse quickly, or if you think your medications are not working as well.

Swallow the capsule or tablet whole and do not crush or chew it. You may break a scored tablet in half if needed to get the correct dose.

Some tablets are made with a shell that is not absorbed or melted in the body. Part of this shell may appear in your stool. This is normal and will not make the medicine less effective.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Your dose and the number of times you take theophylline daily will depend on the reason you are taking this medication.

Follow your doctor's instructions about whether to take your medication with food or on an empty stomach.

Your dose needs may change if you are ill, or if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the form and strength your doctor prescribes.

You will need regular medical tests to be sure you are using the right dose. Do not change your dose or dosing schedule without your doctor's advice.

Theophylline doses are based on weight in children. Your child's dose needs may change if the child gains or loses weight.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using theophylline.

Store at room temperature away from moisture, heat, and light.
