Dear Patient, Thanks for contacting HCM Let me inform you that Sozol is the trade name of drug pantoprazole which is an antacid, Pristiq is the trade name of drug desvenlafaxine which is an antidepressant and Duromine is trade name of phenteramine which is an appetite suppressant. Both Pristiq and Duramine can cause dizziness. To combat the phentermine (Duromine) side effects of dizziness, make sure you’re drinking lots of water, as dizziness is often caused by dehydration.You should also reduce the amount of salt intake and avoid coffee as both cause dehydration. Dizziness with desvenlafaxine (Pristiq) can be reduced by taking it after food at bed time and remember to take it at same time each day. Hope this has helped you Regards
