I've had cough for 2 wks, usually get persistent cough every yr about this time of yr
If it is due to allergies then no. Antibiotics should ONLY be used if there is a bacterial infection. It wont help (and could harm) taking it for virus or allergies. Taking antibiotics, when you dont have active infection, can lead to antibiotic resistance. You CAN use an expectorant like Robitussin (or a store generic) to help loosen secretions or if your cough is dry, you can use a cough suppressant like Dextromethorphan. You will want to take an antihistamine daily to help allergy symptoms if you are not already on one. Something like Claritin or Zyrtec, just the plain ones, not the ones with "D" (like Claritin D) unless you have congestion. They can help reduce the post nasal drip that causes your cough. Just be sure to read all the active ingredients on any product you buy since many are for multi-symptoms and may have some of the same medication ingredients and you dont want to double up on more than one kind of drug.
No, you need an antihistamine. Antibiotics do nothing for allergies and taking them like that makes for resistant bacteria. Now there are times that respiratory allergies can lead to other problems that may need antibiotics, but a dr can decide that. I have a problem if I get tight with reaction to grass pollen, then I sometimes get bronchitis after the fact. But if you have that dry tickle cough from your nose dripping down your throat, post nasal drip, then all you need is an antihistamine and maybe cough syrup.
