I get allergy symptoms every spring, now I'm taking Claritin D...?

The recommended dosage calls for one pill every 24 hours and not to exceed that. Well, I took one this morning at about 7 AM and felt pretty good all day untill about 5 PM and then my symptoms came back. Can I take one every 12 hours and not have to worry, or will it mess with my liver or something? I don't have a family physician to ask and can't afford one.

If It were me I would buy an over the counter nasal spray to use along with the Claritin. The nasal spray prevents some of the allergens from getting into the nasal passages preventing some of the problem. You can try plain saline or make your own with a little salt water and baking soda. It's good for 3 days in the fridge. Use it, dropper or however three or four times a day. They sell several kinds over the counter too. Ask the pharmacist in case you take other meds. I would not take Claritin D more than reccomended. The D part is a decongestant and can cause high BP and other problems. You may want to try benadryl at night, again ask the pharmacist, maybe the plain Clairitin would be better next time and use the spray and maybe benadryl to dry you up, it also helps you sleep. Ask the pharmacist though.
The nasal sprays are preventive...stopping it from getting into the nose so it may help you. I have to use Flonase every day but it's all I have to use. But it is by Dr. RX. Good luck. Source(s): medical education and experience

If your claritin D is a 24 hour extended release med then you cannot take one every 12 hours. You will overdose. Go and get the 12 hour extended release tablets, this works better. I know ...I use the same allergy medicine. I also use some other products that have been helping me with my allergies alot better than Claritin that I have been able to take less and less of the meds and more of the other products better for you.
