Is it safe to take an antihistamine daily?

Most often yes: Otc non drowsy fexofenadine 180mgm for pt over 12yo can safely be used on along term basis in most patients..Always check with with your primary md.

Yes but why: Although antihistamines are a very safe class of medications, the better question is why is there a need to take them daily? If antihistamines are being taken for treatment of nasal symptoms, see an allergist to identify the trigger.

Yes, but...: For most cases of mild allergies, taking a daily dose of antihistamine is fine. If you are taking a sedating antihistamine to help with your insomnia, the effect of these will wear off. Over-the-counter sleep aids have antihistamines or melatonin (already taking). Other options with supplements may be helpful but would need to discuss other contributing factors. www.healthtap.com/dr-DrLuisMatos
