Double dosing: Many over-the counter medications are provided at 1/2 the prescription dose. For example, otc Pepcid (famotidine) is 20mg, whereas the prescribed dose is usually 40 mg. This general principle does not apply to all medications and Allegra-D is a good example. Double dosing the pseudofed in this medication could be dangerous. Always ask the pharmacist about safety before double dosing any otc medications.

Which dose?: The 12-hour version Allegra D contains 120mg of pseudoephedrin and the 24-hour Allegra D contains 240mg of pseudoephedrine. You should not take 2 of the 24 hour Allegra D.

It is safe!: Good morning,
it is safe to take melatonin and allergra together. However, it is not advisable to take melatonin regularly; i would argue. Our biological systems are controlled by feed-back mechanisms, which regulate our wakeful and sleep hours. Melatonin is a natural product which induces sleep. An exogenous (outside) addition of melatonin can theoretically interfere with our nature.

Allergy: Both medications has been used for allergy symptoms. I do not recommend to take it together if your allergy symptoms is not under controlled you can ask your physician to add another kind of medication to your current medication.

Expired medication: Typically, when a medication expires, it's because it loses its potency or effectiveness. There are some medications that, with time, do breakdown with time into harmful substances. Check with your pharmacist to make sure. I would not recommend taking any expired medication.

Avoid doing this: Allegra (fexofenadine) is sold in both 60 mg doses taken twice a day, and a 180 mg dose taken once a day. There is not good data on taking twice the dose at one time. Avoid doing it. If your allergy symptoms are not controlled with the fda recommended dosing, see an allergist. There are certain situations when i prescribe other dosing.

Allegra (fexofenadine) alone: Allegra d contains a decongestant that is a poor long term option. If you are dealing with chronic nasal congestion i would recommend alternative treatment such as a nasal spray like nasonex, (mometasone) flonase, etc.. These are more effective long term options for nasal congestion due to allergies or other triggers.
