- Terbinafine hydrochloride
I would not reccomend this at all. I was described this drug 6months ago. Bad side effects still ongoing rapid weight gain and water retention in putting on 2 stone in less than 6months. No menstrual in ya year Bloatingin the face arms legs and gut. Been to the doctors said nothing can be done so how much longer can you put up with ffeeling like this.should not be prescribed. Makes you feel dreadfull.
- Weight migain with phentermine
I took Phentermine in 1990. At the time I only had about 20 pounds to lose. I actually lost 30. When I stopped taking it, it was like someone opened a "fat door". The weight started coming back even though I did everything exactly the same as when I was on the drug. In six months I had gained 120 pounds. To this day, I cannot get it off no matter what I do. I have been called a liar by several doctors, and have tried every diet known to man. In addition I spend three years with a personal trainer. Nothing has worked.
- Taking phentermine likely caused our baby to have anencephaly.
I used Phentermine for a few months prior to my wedding in December 2013. I ceased taking the phentermine in December 2013 after my honeymoon. In January 2014 my husband and I conceived a baby boy. This was our first child together and we and our families and friends were elated with excitement. At 9 months I had my first ultrasound where you can clearly see our baby's skull was not closed. The on/gyne who took the ultrasound did not diagnose the anencephaly or alert us, instead he referred us to the maternal fetal department at our local hospital. A month later I had another ultrasound performed at the maternal fetal department and was immediately informed and shown that our baby has anencephaly and an abortion was required. The only medication I took prior to pregnancy was phentermine prescribed by my primary care provider. I believe the phentermine is chemically composed similar to Adderral and should have the same warnings. I also believe phentermine causes a mother to be anemic and unable to provide a baby en utero the necessary nutrition for healthy growth. Had I been informed of the risk, I would never have taken this medication. Our baby died at 14 weeks after we were forced through the anguish and torturous of a late term abortion which is against our beliefs. I am now pregnant again, this time with a healthy baby.
- Lyrica varied widely
I was prescribed Lyrica for treatment of chronic pain. It was ineffective, but it knocked out the symptoms of interstitial. However, it also caused rapid weight gain (I went from 110 to 130 lbs. in just a few weeks) and my ankles started to swell. The pain doctor advised me to discontinue the drug, but the urologist suggested lowering the dose. I did, and the swelling went down. I weighed myself daily and watched what I ate, and my weight returned to normal within a month. Subsequently, I continued taking the lower dose and had no further problems. Then I developed severe spinal stenosis, and my dosage of Lyrica was increased to six 75 capsules daily, in addition to 480 mg of morphine sulphate. I tolerated the Lyrica well. After surgery, however, my ankles began to swell again, and although I didn't have a problem with weight gain, I developed a bright red rash from ankles to knees. I dropped the dosage of Lyrica to 50 mg twice daily, and had no further side effects. The rash simply disappeared, with no damage to the skin. Following the surgery, I was able to titrate off morphine completely. I continue to take Lyrica twice daily. It doesn't seem to affect pain (I still ache a bit, as I have degenerative changes in all joints) but it does dampen peripheral neuropathy, which I experience both in my toes and balls of my feet. It also dampens the neuropathy in my forehead, where I had four surgeries to remove a malignant melanoma. I have had no side effects other than those mentioned, and find it interesting the I could tolerate a high dosage of Lyrica prior to surgery, but after surgery could not, and that adverse side effects varied not only with the dosage but with my own physical condition. I don't find it to be highly effective in treating neuropathy, but it does still the tingling enough to let me sleep and take my mind off the condition.
- Trigeminal neuralgia after use of phentermine (2 responses)
I am insulin resistant, unable to lose weight w/diet and exercise. Started us of Phentermine for about 6 days and had increasing symptoms of abscess tooth. Went to dentist, was not a tooth, he thought it was a sinus infection. Antibiotics did not work. My PCP gave me more antibiotics. Did not work. Went to ENT- scoped sinus. It was not my sinuses. Told to take different antibiotics if pain came back. IT DID! Took those, went back to dr- Worse still. Dx with TMJ, given muscle relaxers. That did not work. Pain continued intense. Unable to chew, wear glasses, move my hair, sleep on that side of head. Dx w/Trigeminal Neuralgia. This started with the Phentermine. I want to know if anyone else has suffered this?!

Comments from related studies:
From this study (3 weeks ago):
I've previously been on both Adderall and Phentermine, at different times. I experienced very drastic and noticeable effectiveness. The phentermine helped with weight loss significantly and the Adderall greatly increased my energy levels, self-confidence, elevated mood, and higher concentration and brain activity. I was not on any other medications at the time, though I did need to take melatonin occasionally to help me sleep. Now, I had not been on Adderall or phentermine for about a year, but I was put on Adderall again several months ago. This was about a month after my brother died, so obviously I was experiencing (and still am) grief and depression. I was put on 40mg (twice as much as I used to be on) of Adderall in addition to seroquel XR and Lamictal. I felt like a slug all the time, I felt physically hungrier, and lethargic and apathetic. The adderall did nothing to help these symptoms. I am now on 60mg of Adderall and 37.5mg of Phentermine for weight loss and neither have shown any affectiveness, mentally or physically. My appetite is just as bad, and my brain isn't functioning fast at all. None of the affects of adderall I used to experiences, like increased energy levels, elevated mood, decreased appetite, increased brain activity, and increased self-confidence are present now, and I'm on more adderall than I was on before AND phentermine at the same time!! What's going on?? Both my ADD and weight gain are causing me to become increasingly self-conscious and depressed. Also, it doesn't help that my ridiculous amount of mood stabilizers make me apathetic and detached. I'm under 18 so I'm required to take the medications prescribed to me, but I don't know what to do or why the stimulants aren't effective anymore. HELP!!
nobpdy important on Dec, 19, 2014:
Just saying but u must have been taking vyvanse instead of adderall because the highest mg of adderall is 30mg. If u were taking 40mg and 60mg u must have been taking vyvanse which goes all the way up to 100mg
