Can Blood Pressure Medications Cause Fainting/collapse

Hello,
My MIL has had two fainting spells. She has felt off balanced and on one occurance that I know of Extremely tired. She fainted once at the bank. And before fainting she said she felt very tired. After fainting she also looked like she was having some type of seizure. It also appeared as if she had a smile on her face or a drooped mouth. She had another experience yesterday where she fainted in her driveway and my SIL told me that she had the same shaking that I mentioned when she fell the first time.
They spoke stroke specialist ruled out the possiblity of a stroke. And a relative who is a nurse stated that it could be that her blood pressure medication was too strong. I know also that she is not eating properly. No one can seem to find a cause and I'm concerned because she lives alone. Everyone else is working.
Is there anyone on blood pressure or now of anyone who has had this experience.
thank you

What can I do next?

So What Happened?™

My husband and SIL do believe that it is the blood pressure meds. She was in the hospital yesterday (after her second fainting spell) and they were told that she was very dehydrated. Also they found that her blood pressure was lower in a standing position than in setting. So, they believe that it is possibly the blood pressure meds. They are still waiting for the results of an MRI. She was not near home when she had the second spell so she was taken by EMS to another hospital. They physicians at the hospital were waiting for a call from her regular DR. who never contacted them. So, In my opinion, she probably needs to get another DR. as well.

thanks

First - I would call her doctor NOW rather than later. It is possible that her blood pressure medication is not adjusted correctly for her. However, the doctor needs to make that adjustment. There are a ton of medications out there, it took us about three different meds to find the one that worked the best for my husband. You want to have her looked at though before she falls and hurts herself. You don't want to waste to much time getting more opinions...

This has happen to my mother before and it was her blood pressure meds. I would get her into her DOC to have things checked. Good luck ;)

If she has poor oral intake of fluids and BP meds it may be causing her BP to be too low to sustain proper levels. Make sure she is getting enough fluids and see the Dr who prescribed the BP meds

Yes blood pressure meds can cause the blood pressure to dip to low causing fainting. So can low blood sugar amongst other things. She needs to call her doctor for an eval to make sure that's what it is and then they can adjust her meds.

My grandmother suddenly had fainting and blackout spells. Her doctors thought it was neurological until she landed in the hospital. The doctors there were surprised at how strong her blood pressure meds were and suspected this was part of the problem. Her high dose of meds also caused her to lose her appetite and she was not eating properly or drinking enough. Dehydration/malnutrition was the other part of the problem.
Once they lowered her dosage, she returned back to normal and hasn't had an episode since.
Just goes to show you, that not all docs are in agreement on stuff as simple as blood pressure meds. Have her get a second opinion by a reputable doc.

Hi B.,

I have vasalvagal syncope (fainting spells) & seizures. They put me on a blood pressure medication to help my condition. Symptoms include light-headedness, dizzy, feeling warm, black-outs, shaking, sometimes I fall off balance, and I feel very tired. I've had this condition since 1981 and they have finally gotten it under control after trying different meds and implanting a pacemaker :(
because my condition is sooo severe. You must stay hydrated. I drink alot of water and gatorade and had to increase my salt intake. So your MIL may want to see a cardiologist.

Hope this helps

Absolutely! Meds can cause BP to fall too low and cause weakness, dizziness, fatigue, sweating, lightheadedness, shaking, nausea, etc...and fainting. She definitely needs her BP meds evaluated.

What concerns me, though, is the smile or drooped mouth. Those are signs of a seizure. As one mom said, blood sugar could be a concern, too.

She absolutely needs to be check out by the doc. One easy thing to do is buy a BP monitor so she can check her BP when she feels symptomatic. Have her take it to the doc with her on her next checkup to test it against theirs and make sure it's accurate. Also, ask for a Hemoglobin A1C and a Fasting Blood Sugar test. (It's likely they will order it anyway) and have them test her sugar with a fingerstick there in the office. In our office we have monitors that are supplied by the drug companies at no cost to patients. Perhaps she could ask for one just to have on hand so next time it happens her BS can be checked right away.

That's all I can think of right off hand...stress to her the importance of nutrition...I hope you find some answers.

Keep us posted!

My father in law had an interaction with his eye medication and his blood pressure. His heart rate was down to 36 beats per minute. Get her in to see someone.... it is really important :)

she needs to get to dr and get checked out

B.,

Have them check her thyroid. It sounds like it may be her blood pressure too when she stands up to fast. You may be able to get help from a Commission on Aging to get someone to check in on her.

My mother had fainting spells years ago that were the result of her forgetting that she had taken her blood pressure medicine and she would take it again which would drop her blood pressure too much. She now has someone to dispense her medicines to prevent this from happening.
Also, if she isn't eating well, her blood sugar could drop, which would also possibly cause dizzyness or fainting.
My mother later had fainting caused by her heart slowing down. After wearing a monitor, the doctors gave her a pacemaker.
I don't know if any of this will help, but I wish you well.

Could be her blood pressure meds, especially if she is taking a new medicine or a new dose of the medicine. If I were you, I'd advise her to go and see her doctor ASAP as they may be something else going on. Tell the doc exactly whats going on, and how frequently it's happening. Also, ask about a full cardiac workup...most common cause of fainting is blood pressure problem stemming from an underlying cardiac issue.
Hope it all works out ok.

Your MIL's blood pressure could be too low. She should be checked by the doctor who prescribed the medication. The other thing is that there are studies out there that say many times people who take medication for high blood pressure become diabetic. If that is the case, she could have suffered from a diabetic seizure that doesn't have anything to do with her blood pressure, but her blood sugar level. She should be checked as this could be a deadly combination. There are so many people out there with diabetes that don't even know it until something like this happens. If this is the onset of type II diabetes, before it gets out of hand and insulin is recommended (which has it's own side effects) she should see a doctor to see if this is what is happening and see a nutritionist to see if it can be controlled by a strict diet rather than getting on the insulin merry-go-round. My Dad became diabetic at 50. It is not fun. After 25 years of the insulin merry-go-round, losing part of his leg, heart by-pass surgery he started going to a chiropractic group in Grosse Pointe who have helped him tremendously with his diet and basic nutrition. I just wish we had known about this group before all the bad things happened to him using the typical regular treatment MDs usually prescribe. It is amazing what a good diet and whole food supplements can do to help the body heal itself. Go to www.ahccenter.com
I hope you can find the answers you need!

I know you got a lot of answers and I didn't read them all, but I just read something that said the fainting and exhaustion is caused by the diuretic she probably takes, It may be flushing too much sodium. She has to up her potassium and should have been prescribed it. Definitely talk to her doc. My dad had years of trouble getting the balance of meds right. He ended up with pulmonary edema, caused by those meds. Good luck.

Yes it can, and I believe it says so in the patient leaflet. I was on it for migraines, but my blood pressure is perfect and it lowered mine too much, so I quit taking it. I felt light headed, dizzy, and fatigued all the time while I was on it.

B. -

I agree, your mom should be checked by her Dr., or a new Dr. since hers didn't have the decency to return a call to the EMERGENCY ROOM! How absurd!

Anyway, my mom started taking blood pressure meds a few years ago, and she had fainting spells as well. At one point, she fainted while walking down the street. Long story short, my mom found out she had a tumor growing in her uterus and ended up having a hysterectomy. My mom also (before the hysterectomy) didn't eat a balanced diet, was stressed out about work and family life, and I begged her to drink water. She didn't drink enough water because she took a diuretic also and was afraid she'd retain water if she drank too much (???). Well, now she drinks water and is still stressed out, but that's just her thing, I guess. Since having the hysterectomy she hasn't had any more fainting spells to my knowledge.

I was on a medication that also worked for Blood Pressure. I did notice it made me more apt for 'dizzy spells' (if I rose too quickly.)

However, there could be more going on here. I recommend taking her in immediately for a check up. It could be the Blood pressure or perhaps something neurological occuring. Best to be safe!

Hope all works out well!
