Since some Allergies can be controlled by the environment/climate you live in, in that sense you can. For example, a person moves to the Northwest and develops allergies they never had in Arizona. Other than that, you can get allergy shots but those are not recommended unless the allergy is extremely severe or an absolute pain in the neck on a day to day basis and even then are not a 100% guarantee to work. Medications like Zyrtec can be taken to suppress allergies, but it doesn't make them go away entirely. You can prevent 'attacks' resulting from allergies by just being cautious and smart. Just taking care to not come in contact with the things you are allergic to is probably your best bet.
