Subj: Bontril side effect
I have been taking Bontril for around 4 weeks. In the last 5 days I have developed a nervous tic, where I clench my eyes frequently and blink uncontrollably. Also, my eyes feel dry and irritated almost all the time. It has become so annoying that I stopped taking Bontril, even though it was quite effective for me.

AskDocWeb: Sorry, the instructions say it is not to be used if you are pregnant. Ask your doctor to recommend an alternative.
Subj: I love it!
I love it! I have lost around 10 lbs and am in my 5 th week. I have not experienced many side effects. except for the 1st weeek, it took me longer to fall asleep at night. My mouth tends to be dry, which is good, b/c I drink more water! I am one of those that can not take over the counter diet pills b/c I feel like my mind is going 90 miles and hour but my body feels...blah. They make me feel spacey and Bontril does not, it is very mild, but you have to eat with it, if you don't you will feel the side effects more.
Subj: Addicted to Bontril
I have been taken Bontril for about 5 weeks now but have taken it thoughout the year I think I have become addicted to these pills if I don't take them I feel down and have no enery. I pop up to 7 a day now.
Subj: Working great
I have been taking bontril for 2 weeks now. It is working great. I have already lost 14lbs. Only bad side effect for me is feelings of nausea. Every night. Has anyone else had this problem? Will it go away? Any tips?
Subj: I love it!
I have been taking Bontril for about 8 weeks now. I love it! I have, however, noticed some stomach cramping, but I'm not sure if that is due to the med or stress in other areas in my life. Otherwise, I would say that I'm satisfied. I've lost 20lbs, but I didn't start really dropping weight until the last 2 weeks. I'm not sure why, because I haven't been doing anything differently. Unless it just took time to fully get into my system. I have recommended this medication to friends and family. I'm really grateful this drug was developed. I was never able to take OTC weight loss meds either and feel normal anyways, but this stuff is great!! Thank you to the inventors of Bontril!!
I've been using bontril for about 10 days and it really have reduced my appetite in a big way. I ?would like to know if I would have some kind of problem with migraines. I don't get them very often, but today I did and didn't want to take any medicine, for fear that it would interact with bontril.
AskDocWeb: We saw no mentioned of migraines in the clinical trials for this product. Ask your doctor to recommend something safe for you to take for your migraines.

Subj: Bad case of acne
I had been taking Bontril for about 5 weeks. I experienced the dry mouth and increase in energy which subsided within the first week or two. So far I have lost 7 pounds total. I stopped taking it about a week ago because I was breaking out all over my face, like a bad case of acne. I tried everything to clear up my complextion while I was on Bontril but the acne persisted. Since I stopped using Bontril my face has begun to clear up and there are no new outbreaks.
Subj: Should I worry?
I took Bontril since months ago with no side effects... This time I'm experiencing trouble in breathing ,chest pain, tooth pain, tense jaw, cold extremities and severe headache....a touch of dizziness and insomnia....How much should I worry?
AskDocWeb: Enough to discontinue use of any diet pills. Any diet pill may cause severe symptoms as you have described. If after discontinuing the diet pill and symptoms continue see your doctor and have an EKG done to check your heart rhythm. You will find you will feel so much better, just by changing your eating habits. Make sure your diet includes chicken, fish and vegetables. And exercise, even if it's just walking three times a week. Good luck.
Hello Everyone, I have been taking Bontril for about 2 weeks now and I have not been hungry at all. I have not lost any pounds but my clothes are starting to fit better. Is there a reason that the scale is not showing it? I am starting to get worried that this is not working for me, but I know my hunger is slim to none now, can anyone help?
AskDocWeb: Just the fact that your clothes are fitting better tells you something is happening. It may be that the fat is being replaced with muscle. That would account for the scale not showing a change. Keep at it awhile longer you should see results on the scale too.
What do you think of follinex for a woman with hair that is becoming thinner and thinner--so fine that it will soon be invisible? Is scalp stimulation helpful? Is DHT the chief culprit in hair loss? PLEASE DO NOT USE MY NAME. Thank you. Gratefully,
AskDocWeb: DHT is the chief cause of hair loss in men but most women lose hair for different reasons. Hair loss in women is not well understood by medical science. Scalp stimulation should slow your hair loss to some degree but it is not going to stop it. At present, there is no product we would recommend for women with hair loss. That said, we invite you to share your experience with any hair loss products you try. That would be helpful for other women with this problem.
