I'm currently being prescribed Cyclizine a strong antiemetic used in the UK, I've been taking it for months due to persistent nausea which was having a severe impact on my appetite, cyclizine helps me cope a little better. Problem is I've ran out (very silly of me) and won't be able to get any until Monday afternoon at the latest due to my GP surgery not being open til the. I've read that promethazine hydrochloride branded as 'sominex' (a mild sedative) in the UK produces similar effects as cyclizine. I can buy sominex over the counter and was wondering if it would be a good idea to take until I can get my cyclizine? Any advice?
