I would not be without them. started taking them many years ago for unknown allergy. my lips and my eyes would swell shut the unknown reason. I ended up in the ER and they put me on them and I keep them handy all the time. they also help for sleeping.

I actually found these for $4 later after this delivery but that's fine, $9 is still an excellent price. I got these for my dog who is very itchy but does not have fleas, the vet recommended it. it works well, for dogs you give 1 mg per pound of body weight so 100 lb dog would need 100 mg which would be four tablets

Small pill, easy to swallow. If you let it sit on your tongue it will begin to dissolve quickly and has a bitter taste. It takes about 20- 30 minutes to take effect. Opens up and dries sinuses, allowing for better breathing, and sinus drainage. Relieves the itchiness of sinus drainage down the throat. Calms watering eyes. Follow the dosage recommendations on the label or as prescribed by your doctor, then adjust to your needs as your body dictates. For me if my allergies are mild one pill provides 12 hours of relief... if severe one pill every 3-4 hours is needed.
