What Will Happen If I Took An Expired Store Brand Allergy Pill
Probably nothing: It's not good to take expired medicines, as they may have lost some potency and might not work as well. In most cases though, they are not likely to be harmful to you. For allergy pills, there should be no harm, but they might not work. ...Read more
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Not unsafe...: But probably less efficacious. If you still want to take it, it will likely not harm you but may not work as well as an unexpired dose. ...Read more
New prescription: Medication that has past the expiration date should be replaced. It's unlikely that antihistamines that are beyond expiration date are harmful, but the drug company cannot guarantee the potency. The longer the medication is past the expiration date, the more likely that it has lost some potency. ...Read more
Will a allergy relief pill or an off brand of benedril affect my birth control shot? (Depo) please help!!
No: usually some antibiotics would, better ask whenever you use any other medicines while on hormonal contraception, if in doubt, use an extra method for birth control while using the other medicine, such as a barrier, good that you asked, and always exercise caution with multiple medications, ...Read more
Yes: In general that is a correct statement. ...Read more
I recently purchased a store brand allergy relief in a form of capsules. The expiration date is 12/2015. Is it safe to take and is it still effective?
Expired: Drugs may still be effective or inactive due to the disintegration of the chemicals. Since the effectiveness is not certain it is advisable to use non expired drugs ...Read more
Possibly, see below: It's always hard to tell with these combination products. The best thing to do is to look at the active ingredient list side-by-side. They're usually good at telling you what each ingredient does (cough suppressant, antihistamine, etc.). If two of the same ingredient are in each product - for example, two antihistamines - and especially if both products contain acetaminophen, do *not* take both. ...Read more
Perhaps, one: See prior answer for details about benadryl (diphenhydramine). An over the counter dose is 25 mg (the same dose they put in many 'sleep aides' like tylenol-pm, where the side effect of Benadryl (diphenhydramine) of drowsiness is the main ingredient). If taking it for typical allergies (runny nose, watery eyes, sneezing), could try one tablet. But there are better ones today with less side effects (zyrtec, allegra, claritin, etc). ...Read more
Overdose: Depending on the type of allergy pills, you would become very drowsy. This would constitute an overdose, and requires medical attention. If contemplating doing this, please talk with someone: your doctor; your therapist; a friend; your family; call 911; or go to an er. If you have already done this, please go to an er now, but do not attempt to drive yourself. ...Read more
Probably nothing: Most antihistamines are safe and effective when taken as directed so they probably would't cause a problem if you took them even when you weren't having an allergy problem. ...Read more
Very unlikely BUT...:
Since I don't know what kind please call poison control at 1-800-222-1222.
I don't know any allergy pills that are likely to cause a fatal overdose at that dose but the important question is why you took 15 pills. Were you hoping to die? Please see a psychiatrist or counselor as soon as possible for counseling around the issues that inspired you to take 15 allergy pills. ...Read more
Depnds on med&amount:
Excess decongestant can raise blood pressure to a dangerous level with resultant stroke, heart arrhythmia (with possible death). Extremely high doses of older antihistamines can cause arrhythmias
too much loratadine, Cetirizine causes sleepiness but not much else (up to 4-6 times the normal dose). Fexofenadine doesn't have much experience at extremely high doses but animal data suggests safety. ...Read more
Sneezing again: You could again be plagued with the same symptoms for which you are taking the allergy medications for in the first place. It really would be worthwhile to consult an allergist, find out exactly what the triggers are and then develop a game plan to best treat your allergies. ...Read more
Yes: Your body develops a tolerance to certain medications and if you do not need to take them, then don't. Medications have side affects- including sleepiness. Why risk side affects by taking medication you may not need at this time? Medication is not candy and taking it should not be done lightly. Consult with your md further. ...Read more
I have to take this medicine, but yesterday I found out I have been taking allergy pills instead. Will anything happen?
Will I be ok if I took a allergy pill in the morning and just took an advail pm night tablets will that have a reaction with each other thank you?
Yes: Both types of medication can be taken but thyroid pills should be taken without food or other pills. ...Read more
Perhaps: The most common allergy pills are antihistamines. There is minimal risk of taking an extra new generation antihistamine such as claritin, Allegra or zyrtec. However, taking extra older antihistamines such as Benadryl (diphenhydramine) could result in excessive drowsiness. In general antihistamines are pretty safe class of medications. ...Read more
I took to many allergy pills. I took 2 and forgot and two hours later took 2 more. What can I do will it harm me? Will it harm me
Need: Need to know what pill you took to answer this. Would call your doctor. Likely at this point in time-2 days later- any physical effects would have passed. Speak to your doctor to see if he thinks any bloodwork should be done. ...Read more
My sister is having an allergic reaction and took an allergy pill an hour ago, but the symptoms don't seem to be going away. Can she take another?
What kind?: At any rate she can, or use another kind of antihistaminic, but careful not to drive, depends as well on the trigger and how bad is the reaction, arrange to see a doctor or go to ER if bad reaction, difficult breathing or not improving, goodluck ...Read more
If I took an allergy pill (extra strength 1aday) at 2pm yesterday, it is 7:00 am and I am needing another, can I take now? At work have allergy to cats.
Depends: It is occasionally ok to take extra dose of antihistamine but if you are taking 24 hour antihistamine decongestant combination it would be too much decongestant. Check with your doctor for other medicines that might relieve your symptoms. If you have unavoidable cat exposure you may benefit from a visit to the allergist. ...Read more
The one that works: The most effective one is the one that works. All of them are good, but not all of them work for everyone, just have to try and see. Try a 24 hour allergy medicine and take daily for allergies. ...Read more
Most new generation antihistamines (allergy pills) such as allegra, zyrtec, claritin, etc can be taken once or twice a day meaning their good effects should last 12 to 24 hours. Older antihistamines like Benadryl (diphenhydramine) are taken up to 4 times a day meaning the good effect may last only 4 to 6 hours (and make you sleepy!)
an allergist can assist in finding the right treatment plan. ...Read more
Depends: Multiple factors influence the duration of a medication in the body. Firstly, some medications are "short-acting" while others are "long-acting". Then, different bodies process medications faster than others. Finally, conditions which can affect removal (e.g. Kidney diseases) can cause a delay in elimination of the medication and therefore lingering effects. Typically 4-6h, 12h or 24h. ...Read more
Lots of Options: Over-the-counter non-sedating antihistamines like Allergra, Claritin, and Zyrtec are helpful (I like Zyrtec the best). Other treatments include daily steroid nasal sprays and antihistamine eye drops. Avoidance of triggers is also helpful. If you have a cat, keeping it out of the bedroom is important, HEPA filters, washing cat weekly, frequent cleaning. Allergy shots can also be life-changing. ...Read more
Allergist can help: The most effective treatment for allergic rhinitis are the topical nasal steroid sprays. They are safe and effective, but require a prescription. Allergy pills are usually antihistamines and only block the effect of histamine. An allergist can assist in finding the trigger of the allergies and give advice on avoidance measures and other medications available. ...Read more
No: For antihistamines no.Get a more detailed answer ›
If symptomatic: Antihistamines are generally safe at the recommended doses, and clafritin and Allegra (fexofenadine) do not cause drowsiness. If you have high blood pressure or heart problems pills with a decongestant could be a problem. Antihistamines should be stopped before skin testing. ...Read more
1/2 to 1 hour: Some antihistamines require metabolism in the liver to be converted into the most effective form to block histamine. These antihistamines take at least 1 hour to become effective. However, some antihistamines like allegra, xyzal (levocetirizine) and Clarinex are already in the active form and begin to work as soon as they are absorbed which take about 30 minutes. ...Read more
