you should not use sudafed if you are taking allegra-d. they both contain decongestants and you will likely experience more severe side effects from combining the two. side effects common with decongestants include rapid heartbeat jitters insomnia loss of appetite and increased blood pressure. sudafed is safe to take with rhinocort and allergy eye drops. but if you are still congested while taking allegra-d i would suggest you talk to your doctor to figure out how best to manage your allergies and congestion.
i take allegra-d sometimes use allergy eye drops and rhinocort. recently i added sudafed. is ok to combine these drugs?
