Theo-24 CR is a brand name for a sustained‑release tablet that contains theophylline as the active ingredient. It is formulated to release medicine gradually over time so it helps maintain a steady level in the bloodstream.
Theophylline belongs to the methylxanthine family. It is used as a mild bronchodilator, meaning it can help relax the muscles around the airways in the lungs. This can make breathing easier for some people with chronic breathing problems.
In the United Kingdom, access to this medicine may require a prescription depending on local rules and your health plan. Your doctor or pharmacist will tell you whether Theo-24 CR is suitable for you and how it should be used within your overall treatment plan.
Theo-24 CR is not a fast-acting rescue medicine. It is intended to be used regularly under medical supervision to help control symptoms over time, alongside other treatments for lung conditions. If you have questions about whether this medicine is right for you, discuss them with your clinician or pharmacist.
Theo-24 CR is used as part of maintenance therapy for certain chronic lung conditions. It can help reduce symptoms such as breathlessness, coughing, and wheeze when used with other prescribed therapies.
It may be prescribed when short-acting inhaled medicines alone do not provide sufficient relief throughout the day. In some cases, it is added to a treatment plan to help improve overall lung function and daily activity levels.
This medicine is not intended to treat an acute breathing emergency or a sudden asthma attack. If you experience an acute worsening of breathing symptoms, you should follow your action plan and seek urgent medical help or use a rescue inhaler as advised by your clinician.
Your doctor will decide whether Theo-24 CR is appropriate for you based on your medical history, current treatments, and how well your symptoms are controlled. Do not change your regimen without medical advice, and always use Theo-24 CR as part of a supervised plan.
Theophylline works in several ways to help breathing. It relaxes the smooth muscles around the airways, which can widen the passages and make breathing easier. This relaxation is one part of its bronchodilator effect.
There is also evidence that theophylline can influence certain chemical signals in the lungs that may contribute to reduced inflammation and improved airway function. The exact way it works is complex, and the degree of benefit can vary between individuals.
Because Theo-24 CR is a sustained-release tablet, it is designed to provide a steady supply of theophylline over time. This helps avoid large peaks and troughs in the amount of medicine in the blood, which can help stability of symptoms and reduce certain side effects for some people.
Overall, Theo-24 CR is intended to be a long‑term part of an overall treatment strategy for eligible lung conditions. Your response to treatment will be monitored by your doctor, who may adjust the plan based on symptoms, lung function tests, and any side effects you experience.
Use Theo-24 CR exactly as prescribed by your doctor. Do not change the dose or dosing schedule without medical advice. If you are unsure about your instructions, ask your pharmacist for clarification before continuing.
Swallow the tablet whole with a full glass of water. Do not chew, crush, or break the tablet, as this can affect how the medicine is released in your body. If you have trouble swallowing, talk to your pharmacist or doctor for alternatives.
Take Theo-24 CR at the same time each day. Maintaining a regular schedule helps keep the level of theophylline in your blood steady, which can improve how well the medicine works and reduce side effects for some people.
If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not double dose to make up for a missed one. If you are unsure what to do after a missed dose, contact a healthcare professional for guidance.
Do not stop taking Theo-24 CR suddenly without speaking to your clinician. Your doctor may advise a gradual reduction if you need to stop for a medical reason. Always follow their instructions and report any new or worsening symptoms promptly.
Theo-24 CR may not be suitable for everyone. Do not take this medicine if you have had an allergic reaction to theophylline or any related medicines in the past. Signs of an allergic reaction can include rash, itching, swelling, severe dizziness, or trouble breathing.
You should not use Theo-24 CR if you have certain significant heart problems or severe liver or kidney disease, unless a clinician has assessed that it is appropriate. Your doctor will review your medical history to determine safety in your case.
If you have active stomach ulcers or a history of severe stomach problems, discuss with your doctor before taking Theo-24 CR. In pregnancy or breastfeeding, you should only use this medicine if a clinician has judged the benefits to outweigh any potential risks and with careful monitoring.
Children and adolescents may use this medicine only under strict medical supervision and with a clinician’s explicit instructions. Do not give this medicine to someone else, even if their symptoms appear similar.
Theophylline levels in the blood can be influenced by other medicines, certain foods or beverages, and changes in health status. Your clinician may check blood levels when you start Theo-24 CR or if your treatment changes. This helps ensure the medicine remains safe and effective for you.
Some medicines and substances can raise the amount of theophylline in your blood, increasing the risk of side effects. Examples include certain antibiotics and other drugs your doctor may choose to avoid or adjust. Always tell your doctor and pharmacist about all medicines you take, including over‑the‑counter medicines, vitamins, and herbal products.
Caffeine and other stimulants can increase the stimulating effects of theophylline. Limit or avoid large amounts of caffeinated drinks (such as coffee, tea, and energy drinks) if advised by your clinician. Your doctor may give specific guidance based on your situation.
Smoking can alter the way your body processes Theo-24 CR. If you start or stop smoking, tell your clinician, as this may require a change in the dosing or monitoring plan. If you experience new or worsening symptoms, contact a healthcare professional promptly.
If you notice any signs that could indicate a serious reaction — for example chest pain, severe vomiting, confusion, tremor, or a very fast or abnormal heartbeat — seek urgent medical help. Do not assume these are minor side effects, especially if they are new or worsening.
Like all medicines, Theo-24 CR can cause side effects in some people. Many people tolerate the medicine well, especially when it is started under medical supervision and when blood levels are monitored.
Common side effects can include nausea, vomiting, upset stomach, and occasional heartburn. Some people report sleep problems, headaches, or a feeling of restlessness or jitteriness. These often occur early in treatment and may improve with time or dosage adjustments.
Less commonly, you may notice tremor, a faster or irregular heartbeat, or dizziness. If these become persistent or troublesome, contact your clinician for advice.
Very rarely, individuals may experience severe allergic reactions or seizures. If you experience symptoms such as swelling of the lips or tongue, severe rash, trouble breathing, or seizures, seek urgent medical help immediately and contact your healthcare team as soon as possible.
Carry on taking Theo-24 CR unless your doctor instructs you to stop. Do not ignore new or worsening symptoms, and report them to your healthcare professional so they can assess whether any change to your treatment is needed.
Theophylline can interact with several medicines, foods, and other substances. Interactions can change how Theo-24 CR works or increase the risk of side effects. Always tell your doctor about all medicines you take, including prescription drugs, over‑the‑counter products, and herbal supplements.
Important interactions may occur with certain antibiotics, such as macrolides (for example, erythromycin or clarithromycin). These can raise theophylline levels in your blood. Your clinician may adjust your treatment or monitor you more closely if such medicines are prescribed.
Some medicines used for heart rhythm problems, other stimulants, or certain anti-seizure medicines can also interact with theophylline. Your pharmacist will check for potential interactions with any new medicine you are prescribed or plan to buy over the counter.
Keep to a consistent caffeine intake and avoid very large doses of caffeine while taking Theo-24 CR unless your clinician advises otherwise. If you start or stop smoking, tell your clinician, as this can change how the medicine is processed in your body.
If you are unsure whether a medicine you plan to take with Theo-24 CR is safe, ask a pharmacist or clinician before starting it. Do not start new medicines or change dosages without professional guidance.
If you are pregnant or planning to become pregnant, talk with your doctor or midwife before taking Theo-24 CR. The decision to use this medicine during pregnancy depends on the balance of potential benefits and possible risks to the fetus.
During pregnancy, theophylline may be used only if the clinician judges that there is a clear benefit. The same careful assessment applies to use while breastfeeding, as the medicine may pass into breast milk. Your clinician can discuss safer options or monitoring strategies if you are pregnant or breastfeeding.
If you become pregnant while taking Theo-24 CR, inform your healthcare team promptly so they can review your treatment plan. Do not stop the medicine suddenly without medical advice, as this could cause changes in your symptoms.
The effect of Theo-24 CR on breathing may take several days to become noticeable. Some people notice gradual improvements in daily symptoms, while others may require ongoing monitoring and adjustments by their clinician. If you have concerns about how well it is working, speak with your doctor or pharmacist.
If you remember soon after a missed dose, take it as soon as you can. If it is close to the time for your next dose, skip the missed one and resume your regular schedule. Do not take two doses at the same time to make up for a missed dose.
Many medicines can interact with theophylline. Always tell your doctor about all medicines you are taking, including over‑the‑counter products and herbal supplements. Do not start new medicines without checking with a healthcare professional.
Contact your clinician if you notice new or worsening breathing symptoms, persistent stomach upset, tremor, a change in heart rhythm, confusion, or severe dizziness. Seek urgent medical help if you experience chest pain, severe vomiting, or seizures.
Moderation is advised. Consult your clinician about alcohol use, as drinking large amounts can affect how your body responds to the medicine and may increase side effects in some people.
Theophylline can occasionally cause dizziness, tremor, or sleep disturbances in some people. If you experience these effects, avoid driving or operating heavy machinery until you know how the medicine affects you.
The tablet can be taken with or without food, but try to take it in the same manner each day. If you have stomach upset, taking it with a small amount of food may help, but follow your clinician’s instructions.
Do not stop the medicine abruptly without medical advice. Your clinician may suggest tapering the treatment to avoid a return of symptoms or other effects on your health.
Use in children and adolescents should be guided by a healthcare professional. The suitability and dosing depend on age, weight, and medical history, and must be determined by a clinician.
Store at room temperature in a dry place away from sunlight. Keep out of reach of children. Do not use the medicine after the expiry date printed on the packaging.
