"i was hospitalized within the first 3 weeks of taking tricyclen as i had a severe side effect. it created excess spinal fluid in my body causing pressure on my brain. this required two lumbar punctures to help drain my spinal fluid following by a week of being bedridden. 

please please please talk to your doctor before taking this. i have never had a problem like this with bc before until i got put on tricyclen and threw the rest of them out."
