Overdosing Meds: Loratadine and cetirizine are both antihistamines, and carry side effects including sedation and drowsiness, among others. Increasing the dose of one agent, or combining agents, may increase the likelihood and severity of adverse effects and potential drug interactions. You should consult a physician before modifying medication instructions. ...Read more

Dry eyes. Prescribed Loratadine for sinus infection. Make eyes a lot drier. Can replace antihistamine with decongestant to control post nasal drip?

Dry eyes. Prescribed Loratadine for sinus infection. Make eyes a lot drier. Can replace antihistamine with decongestant to control post nasal drip?

Try nasal steroid: You'd be better off with a nasal steroid which may take a few days to be truly effective. Loratadine does not relieve nasal congestion and thus of little use in sinus infection. ...Read more

Take off loratadine : Or the doxylamine, both are antihistamines and would interact. If you have high blood pressure, you want to avoid the phenylepherine. Otherwise, rest and fluids, would help, good luck with fighting your cold symptoms ...Read more

Hello my favorite doctors! Just wondering if the clairitin that doesn't have the decongestant in it keepsyou awake as well? I've heard this complaint.

Unlikely: Claritin (loratadine) is considered a non-sedating antihistamine. By package insert it is associated with 7% sedation. Higher doses and taking medication that slows the metabolism of loratadine such as erythromycin, cimetidine (Tagamet) or ketoconazole can cause sedation even with 1 tablet. Rarely, it is an upper, but this is unusual. ...Read more

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

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. ...Read more
