Common use

Theo-24 is an oral bronchodilator medication containing the active ingredient theophylline, a xanthine derivative prescribed for the treatment and management of asthma, chronic bronchitis, emphysema, and chronic obstructive pulmonary disease (COPD). As a breathing medication, Theo-24 provides sustained relief from bronchospasm and helps maintain open airways for easier, more comfortable breathing throughout the day.

Theophylline is chemically related to caffeine and works as an airway relaxant by relaxing the smooth muscles in the lungs and chest. This bronchodilator action opens constricted airways, allowing air to flow more freely in and out of the lungs. Additionally, Theo-24 makes the lungs less sensitive to allergens, irritants, and other triggers that can provoke bronchospasm, making it a valuable component of comprehensive asthma treatment and COPD medication regimens.

When you buy Theo-24 online, you receive a controlled-release formulation designed to provide consistent, around-the-clock bronchodilation. Theo-24 generic theophylline delivers the same sustained-release benefits as the brand-name product, offering an affordable option for long-term respiratory disease management. Whether used alone or alongside other breathing medications, theophylline remains a well-established choice for patients who need reliable airway relaxant therapy.



Dosage and direction

Take Theo-24 orally with or without food, accompanied by a full glass of water. The controlled-release tablets must be swallowed whole — do not crush, break, or chew them, as this disrupts the sustained-release mechanism and may cause an unsafe rapid release of theophylline into your system. If you are taking Theo-24 on a once-daily basis, avoid taking the dose at bedtime, as theophylline may interfere with sleep.

The recommended starting dose for adults is one 150 mg tablet every 12 hours. Your doctor may gradually adjust this dosage based on your individual response and blood theophylline levels, up to a maximum of 600 mg per day. Dosing for children aged 6 to 16 years is calculated based on the child's body weight, as determined by the prescribing physician.

Note: These dosing guidelines are provided for informational reference. It is essential to consult your doctor before starting this bronchodilator to determine the optimal dose for your specific respiratory condition and to buy theophylline at the right strength for your needs.



Precautions

Use Theo-24 with particular caution if your medical history includes liver disease (hepatic impairment), diabetes mellitus, hyperthyroidism, or hypertension. These conditions can affect how your body metabolizes theophylline, potentially leading to elevated blood levels and increased risk of side effects.

Do not consume alcohol while taking this COPD medication, as alcohol can alter theophylline metabolism and increase the likelihood of adverse reactions. Important note for smokers: tobacco use significantly accelerates the body's clearance of theophylline, meaning smokers may require higher or more frequent doses compared to non-smokers. Inform your doctor about your smoking status so your dosage of this breathing medication can be properly calibrated.

Theo-24 should not be used during pregnancy or while breastfeeding without explicit medical guidance from your healthcare provider. If you buy Theo-24 online, always discuss your complete health profile with your doctor first.



Contraindications

Theo-24 is contraindicated in patients with known hypersensitivity to theophylline or any other xanthine derivative, or to any component of the formulation. Do not take this bronchodilator if you have an active peptic ulcer or a seizure disorder such as epilepsy, as theophylline may worsen these conditions.



Possible side effect

Theo-24 may cause a range of side effects. Serious adverse reactions that require immediate medical attention include:

seizures (convulsions);

worsening of your respiratory condition or symptoms suggestive of new illness;

severe or persistent nausea and vomiting, headache, rapid or irregular heartbeat, and insomnia;

coughing up blood or producing vomit that resembles coffee grounds;

persistent fever;

marked restlessness, irritability, nervousness, or jitteriness;

tremors; or

significantly increased urination.

Less serious side effects of this asthma treatment may include:

mild nausea, decreased appetite, or weight loss;

restlessness, mild tremor, or difficulty sleeping;

headache, lightheadedness, or dizziness.

If you experience any of these symptoms while taking theophylline, contact your doctor promptly for evaluation. Report any unusual or unexpected side effects to your healthcare provider.



Drug interaction

Theo-24 interacts with a number of commonly used medications. Important interactions include carbamazepine, cimetidine, enoxacin, ephedrine (and similar compounds found in cold medicines and diet supplements), erythromycin, fluvoxamine, propranolol, rifampin, St. John's wort, and thiabendazole. These drugs can either increase theophylline blood levels (raising the risk of toxicity) or decrease them (reducing the effectiveness of your bronchodilator therapy).

An interaction between two medications does not always require discontinuation of either drug, but it does necessitate careful monitoring and possible dose adjustment. Consult your doctor about how any potential drug interactions should be managed while you are using this airway relaxant and xanthine-based breathing medication.



Missed dose

If you forget to take your dose of Theo-24, take it as soon as you remember. If it is nearly time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take a double dose to compensate. Resume your usual dosing at the regular time the following day.



Overdose

Theophylline overdose is a serious medical emergency. Symptoms may include severe nausea, persistent restlessness, vomiting, tremors, irregular or rapid heartbeat, insomnia, and seizures. Seizures caused by a theophylline overdose can result in death or permanent brain damage. If you suspect an overdose of this bronchodilator, call emergency medical services immediately. Do not wait for symptoms to worsen.



Storage

Store Theo-24 at room temperature between 59-77 degrees F (15-25 degrees C), protected from direct light and moisture. Keep this asthma treatment and COPD medication out of reach of children and pets. Do not use after the expiration date on the packaging.
