Hi everyone, I'm new to this community. My neurologist just informed me that Osteoporosis and shrinkage of the Cerebellum are very serious side effects for long term users of Dilantin. Does anyone know more about this? I've been taking 500mg of Dilantin for over 30 years since I was a teenager, and now I'm terribly worried. Not one of the neurologists had mentioned anything about this over the years, and now at 46, I've learned that I may have severe osteoporosis.

Hello AB, welcome to the medhelp forum. Phenytoin can cause certain side effects like dizziness and mental confusion. Some people may also manifest incoordinate movements. Weight gain is not a documented side effect. It could be related to your alcohol consumption or wrong dietary habits and lack of exercise. An occasional one or two drink may be fine but moderate or large amount can cause significant increases in blood levels of phenytoin due to induction of hepatic enzymes.

A few weeks ago I woke up with yellow crust on the corner of my lips and it went away in 2 days, and today I woke up and it's in the exact same spot again except a little more then before. It doesn't hurt or itch, it feels like my lips are very very dry. I don't smoke, I have grandmal seizures and my medication is phenytoin and kepra but I didn't read anywhere that would be a side effect so I'm worried this could be a STD or something.

Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make you feel dizzy or lightheaded, and maybe even faint. Orthostatic hypotension may be mild and last for less than a few minutes. However, long-lasting orthostatic hypotension can signal more-serious problems, so it's important to see a doctor if you frequently feel lightheaded when standing up.

drugs like gabapentin, phenytoin are used for hemifacial spasm. Other options are botulinum injections and microvascular decompression surgery. Hope this helps. Take care.

No problem......I appreciate the reply.

Has anyone out there with Fibromyalgia ever been diagnosed with Orthostatic Hypotension? I have been miserable for months....nine months to be exact. I have seen over five specialists...all of them stumped until I seen an endocronolgist recently. I have had Fibro since 1999. I have had chronic pain that I have dealt with it well until this past year. I have always..."sucked it up" so to speak and gone on every day to do what I needed to do.

I have been diagnosed with orthostatic hypotension, but the doctor's don't know the cause. I started getting lightheaded on a daily basis about 4 months ago. I am taking Pindolol (10mg 2x daily) and Fludrocortisone (.01mg once daily). I have also increased my sodium and drink 2-3 liters of fluids a day. I have never fainted, and have been able to resume exercising daily. The lightheadness though continues to be there if I am standing or sitting for most of the day.

My boyfriend and i both have low blood pressure and his was inherited from his father where all his other 2 siblings are inherited too. As for mine, it was passed down from my grandmother to my mum and to me. I've heard that if both parents have hypotension, their baby is most likely to be unhealthy. Does that mean that it's impossible for my boyfriend and i to have a complete and healthy family? His parents strictly object their children's partners to have hypotension.
