My throat feels dry, have 37.5 temperature and sleepiness, after having loratadine 10 mg. and phenylephrine 5mg. together. is that normal?

Can be related but: The 37.5 temp may be normal unless you have an underlying illness as the reason to take the meds. Temperature normall ranges are like a Bell Shaped Curve and you are in the normal curve. Loratidine is an antihistamine and this could dry you and make you sleepy. The phenylephrine may actually have a different effect. In essence this all appears normal and physiological.
