In conjunction with Losartan 100mg, my Gp has prescribed Felodipine ER PLE 5mg to try and lower my BP which has been in the range of 160/95 for the past few weeks. I took my first Felodipine yesterday and although I had been warned of possible side effects I didn't expect so many, so fast! Within an hour I had severe headache & neck ache. Flushed red face, constant urge to urinate, nausea, sleeplessness, and today I have slight tremors in my hands/arms. Should I continue with this medication? I understand that some of these symptoms may pass after I have been on this medication for a week or two, but I am dubious about taking anymore!
