My mother 50 female is suffering from some sharp pains at eyes, ear,neck, head etc. These will go away when she took pregabalin IP 75 mg + mecobalamin JP 750 mcg combination drug. It is prescribed by our doctor for vitamin B12 deficiency. My doubt is the pains occurring to her are neuropathic? And she had high blood Pressure. She is using telmisartan 80 mg + hydrochlorothiazide 12. 5 mg to control blood pressure along with rabeprazole sodium 20 mg for gas and atorvastatin 10 mg for cholesterol. So can she use pregabalin IP 75 mg + mecobalamin along with above medicines? And she is using this only when pains occur. It it good to use this medicine when ever needed? If not what is best time to use it.
