Generic Medication guide:
What is Celebrex and when is it used?
Celebrex is a brand of Pfizer. The active substance of this product is Celecoxib which is an anti-inflammatory, antipyretic, and analgesic agent.
If you wish to buy Celebrex at a lower than the regular price, you should opt for a generic medication. For instance, at our drugstore, you can get the same product sold under a different name made by Cipla.
Celebrex has anti-inflammatory, painkiller and anti-fever activity. The principle of action of the formulation is the suppression of the synthesis of prostaglandins by selective inhibition of the COX-2 enzyme (cyclooxygenase), which is involved in inflammation.

The agent is well absorbed when taken orally. After taking one dosage from 100 to 200 mg, the highest plasma level is reached on average in three hours and is proportional to the doses. Celebrex is metabolized in the liver with the participation of the cytochrome P-450 isoenzyme system.
It is washed out mainly with bile in the form of metabolites.

Dosages of Celebrex
The pills are taken by mouth with a full glass of water. The medication can be taken with or without food. To prevent the negative impact on the stomach, it is better to take it after a meal.
During the therapy, the minimum effective dose should be used. The length of the course is set by a healthcare provider and is preferably short.
- For osteoarthritis: 100 mg is taken twice a day or 200 mg once a day.
- For rheumatoid arthritis: 100 mg is taken twice a day. If required, the dose can be raised to 200 mg twice a day.
The highest daily dosage must not exceed 400 mg.
Individuals over 65 years of age do not need a dosage lowering. But in older individuals with a bodyweight of less than 50 kg, the therapy should be started with the minimum recommended dosage.
The maximum course of treatment is 2 weeks. If the desired result is not achieved, the medication must be discontinued.
Your doctor may prescribe you another dosage regimen based on your individual features and condition. Thus, even though you can buy Celecoxib without Rx from our drugstore, we strongly recommend you to consult your healthcare provider first.

Interaction with other medicines
Before you order Celebrex, make sure to check with your physician that you don’t take any medicines incompatible with this drug.
- Celecoxib is metabolized with the participation of cytochrome P450 CYP2C9. If an individual has low CYP2C9 activity, the medication should be prescribed carefully due to a significant rise in the level of the formulation in the blood due to a drop in metabolic clearance.
- The formulation can interact with medicines that are metabolized with CYP2D6.
- In the use of warfarin or similar medicines with Celebrex, cases of severe and even fatal bleeding can sometimes be observed. Due to the fact that when taking Celecoxib, there is an elongation of the prothrombin time, after the start of use or when the dose of Celebrex is changed, anticoagulant activity should be observed.
- The simultaneous use of Fluconazole in a dosage of 200 mg once a day leads to a two-fold elevation of the plasma level of Celebrex. This raise is observed due to the inhibition of medication metabolism by Fluconazole. In individuals receiving a CYP2C9 inhibitor, Fluconazole, Celebrex use should be started with the minimum recommended dose.
- Prostaglandin inhibitors may reduce the tension-lowering effect of ACE inhibitors. -In some individuals, NSAIDs may diminish the effect of diuretics. - Plasma lithium concentrations increase by about 17% due to simultaneous use with Celecoxib. Careful monitoring is required for patients taking lithium with Celecoxib.
Precautions for Celebrex use
- NSAIDs, including Celecoxib, raise the danger of serious adverse reactions on the part of the digestive tract such as bleeding, ulcers formation, and others. These complications can occur at any time without warning signs, a fatal outcome is possible. Elderly individuals have a higher risk of serious complications; the likelihood of these complications also increases with prolonged use.
- In senior patients, in low bodyweight, in symptoms of heart failure and with the failed liver function of moderate severity, therapy should be started with minimal doses. - In some individuals taking Celebrex, fluid retention and edema were observed, so it should be used carefully in any heart conditions and other diseases associated with fluid retention.
- During the therapy, it is necessary to control peripheral blood and the functional state of the liver and kidneys.
- It is necessary to refrain from potentially hazardous activities that require increased attention, as there may be a violation of accommodation and a longer reaction time.
