Why would you rather be injected with drugs instead of eating more to gain weight?

Vicki is right, you really need to talk to your doctor or a certified nutritionist about gaining weight, if that's your goal.

Just so you know, Periactin is an antihistamine and is used for seasonal and year-round allergy symptoms such as watery/itchy eyes, runny nose, and sneezing. It is also used to relieve itching and hives caused by some skin conditions.

Yes, side effects of Periactin include increased appetite and weight gain, but they also include drowsiness, dizziness, blurred vision, loss of coordination, upset stomach, constipation, and dry mouth, throat and nose.

I wouldn't try taking a medication -- any medication -- for anything other than its intended purpose without talking to a doctor first.

Keep in mind, it's much more difficult to lose weight than to gain it, so work with a doctor or nutrionist to make sure you stay healthy no matter what.

I'm 26 years old 4'11 & 89lbs. So I have alot of understanding on your position. Can't really eat alot if there is no appetite. I tried everything including super carb & protien diets. Caloric increases...Nothing worked. Eventually my doctor prescribed Periactin for me & it worked. Many medications have other uses & as a nurse I knew that Periactin is also widely used in treatment for anorexia & decreased appetite. It does have side effects but for me they only lasted for the first 2 weeks & then as my body got accustomed to the medication, they faded. Medications can work for each individual differently as each individual's body is different. I started off taking it in smaller 2mg doses & gradually increased to 4mg three times a day. I went from being 92lbs to 105lbs in about a month. After that it pretty much reached its peak for me but I was happy with what was accomplished. I got pregnant shortly after that & had stopped taking it so now that I've had the baby I'm super skinny again. Going to see my doctor soon to see if I can resume the periactin again. Bring it up to your physician & see what he suggests. It may or may not be an option for you.
