Hello dear, Celebrex (pharmacologically Celecoxib) is a nonsteroidal anti-inflammatory drug used to treat pain or inflammation. If your symptoms are due to the medication, then symptoms will be relieved as it is cleared away from your body which occurs by 24-48 hours. However, other causes for the symptoms need to be ruled out, such as: 1. Any pathology in the vestibular apparatus in inner ear (it is associated with maintenance of body posture & balance) 2. Any fluctuation in blood pressure levels (such as Postural Hypotension) 3. Decrease in blood sugar levels (Hypoglycemia) 4. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium, etc. which interferes with blood formation & nerve conduction. Symptomatic relief can be obtained with Vestibular sedatives like Betahistine, nervigenic agents (like Vit B6, B12, Folic acid) & Pantoperazole (to be taken 30 minutes before meals). Investigations like complete blood count, estimation of blood pressure and blood sugar levels and vestibular function tests will be helpful in clinching the diagnosis. Meanwhile, maintain adequate hydration, take a healthy balanced diet & avoid stress and sudden head movements. Wishing a good health. Take care.
