I have a concussion caused from falling out of a broken chair and hitting my head on the wooden part. It happened 3 weeks ago this passed Thursday. I am seeing a neurologist who keeps changing my meds because I get terrible side effects. The lastest meds are Tizanidine 2 mg at night which I took last night and woke up dizzy and weak. The newest which I take in the am for the first time tmo is Escitalopram 10 mg. I was told I could take Advil and Promethazine. My concern is the interaction if all these meds. I was on Nortriptyline 10 mg last night. The side effects were bad ... made my head hurt worse ... so the neurologist took me off if it today and prescribed Escitalopram 10 mg. I have asthma and some of these drugs are effecting my breathing. It is time to take the Tizanidine and I just don t want to take it. Is it ok to take the Advil with the Tizanidine? I feel like just skipping it and taking a few Advil. My regular dr had given me prescription pain killers which the neurologist took me off of. I just don t know what to do. How many mg of Advil should I take. Dr said do not take Aleve. I have had too many pain killers with Tylenol in them so Dr said to change to Advil which upsets my stomach too. I took one Advil this afternoon 200 mg but it has worn off anfpd my head is starting to hurt again.
