Blood Thinners (Definition)

Agents which slow ;/or break down blood clot formation in up to 3 different ways (they do not decrease blood viscosity; thickness.) (1) some inhibit platelet function (e.g. Aspirin, clopidogrel, etc.). (2) others interfere with some of the clot forming proteins (warfarin, dabigatran, rivaroxaban, etc.), (3) others stimulate the blood clot destruction ...Read more

How long does naproxen last as a blood thinner?

How long does naproxen last as a blood thinner?

About 24 hours: Naproxen is the brand name for naprosyn (naproxen) a non-steroidal anti-inflammatory medication. It reversibly inactivates new platlets for about 24 hours. This means the blood is "thinned" or less likely to clot during that 24 hours. Aspirin alternatively irreversibly inactivates platlets so they are less sticky for about 7 days. In both cases these are generalizations that differ person to person. ...Read more

I feel like Adderall (dextroamphetamine and racemic amphetamine) is making my circulation bad, will taking naproxen make the blood thinner and easier to flow?

I feel like Adderall (dextroamphetamine and racemic amphetamine) is making my circulation bad, will taking naproxen make the blood thinner and easier to flow?

Amphetamines: Adderall (dextroamphetamine and racemic amphetamine) is an Amphetamine, which is related to Adrenalin in it's actions. Adrenalin is the Fight or Flight hormone. Adrenalin speeds up the heart, raises blood pressure, dilates the pupils, increases sweating and breathing rates. Amphetamines do the same thing. Many adults are mistakenly diagnosed and prescribed stimulants like Adderall (dextroamphetamine and racemic amphetamine), which have many potentially dangerous side effects. ...Read more

A geriatric patient who has had open heart surgery years ago and recently had a stroke and is on blood thinners, can he take aleve (naproxen)?

A geriatric patient who has had open heart surgery years ago and recently had a stroke and is on blood thinners, can he take aleve (naproxen)?

I will avoid: Nsaid's like Naproxen in geriatric patients specially if they are in blood thinners. 50 millions american have gastritic/ulcer disease induced by nsaid's and around 3% of those will bleed from the disease. Also nsaid's are associated with stroke and heart attacks. Use tylenol (acetaminophen) without using more than 3, 000 mg a day. Consult your doctor. ...Read more

I get blood in stool after use of aleve- when will it stop?

When you stop: Using aleve (naproxen) or Ibuprofen and other nsaid's. In either case you need to see a GI doctor for proper evaluation and diagnosis and treatment. This could be something serious that is occult and only aggravate by the aleve (naproxen). Catching something bad early is your best shot at having a good prognosis. ...Read more

I took aleve (naproxen) the night before I got blood work done and I had my creatinine checked. It came out to. 99. Could the aleve (naproxen) have messed up my results? Could it have made it lower than it actually is?

I took aleve (naproxen) the night before I got blood work done and I had my creatinine checked. It came out to. 99. Could the aleve (naproxen) have messed up my results? Could it have made it lower than it actually is?

No: Depends on the lab but mostly a normal creatinine is about 0.99 and this would not be an abnormality.
Aspirin like drugs lower the blood flow thorugh the kidneys and this would, if anything, raise the creatinine not lower it. ...Read more

Hello is it normal to have blood in your stool when you're taking new medicines such as Aleve (naproxen) or mixing prescribed medicine with aleve (naproxen)?

Hello is it normal to have blood in your stool when you're taking new medicines such as Aleve (naproxen) or mixing prescribed medicine with aleve (naproxen)?

NOT GOOD, stop Aleve (naproxen): Never, unless with a doctor's expressed advice, mix medicines. Aleve (naproxen) is an effective inhibitor of platelet function so it can make you bleed. Aleve (naproxen) can cause ulcers (anywhere in the GI tract), which can then bleed. Stop the Aleve (naproxen) at once, and seek medical attention now before a little bleed turns into a life-threatening one. ...Read more

My friend took 40 aleves (naproxen) last night and has had horrible stomach pains all day. She is bleeding black blood from her vaginal region. Will she die?

Emergency Dept.: At your local hospital is what is needed ASAP. Follow that up w/treatment by a mental health professional to get to the root of the cause for the overdose. The staff in the ED may give you a referral if you don't have one. Thanks for being a caring friend. Peace and good health. ...Read more

Is Aleve (naproxen) or ibuprofen safer to take if you have high blood pressure and you are on blood pressure medication?

Is Aleve (naproxen) or ibuprofen safer to take if you have high blood pressure and you are on blood pressure medication?

Both affect BP: All NSAID's, including ibuprofen and naproxen, have the potential to increase blood pressure (BP). In most people the change is small but, on occasion, a significant elevation of BP may occur. Consider monitoring your BP (call your MD staff so they can assist you in arranging for you to drop in randomly for 3-6 BP checks over the next several weeks) to see if BP is affected while on a NSAID. ...Read more

Last few times I had a bowel movement I had drops of blood. My stool is really hard but its not soft either, I've been taking Aleve (naproxen) a bit to. What is it?

Heme + stool: Could be hemorrhoid, could be intestinal bleeding from NSAID (aleve) use (but this is usually upper GI bleeding). Best to always see GI and get any rectal bleeding evaluated. Best wishes. ...Read more

With PCOS, how do you know if you have insulin resistance? Recently started having high blood sugar, and cholesterol. Now I'm on metformin. Also, is taking Aleve or Ibuprofen okay on met?

With PCOS, how do you know if you have insulin resistance? Recently started having high blood sugar, and cholesterol. Now I'm on metformin. Also, is taking Aleve or Ibuprofen okay on met?

Insulin resistance: If you have PCOS, you have insulin resistance by definition. It is part of PCOS. That does not mean that you have diabetes, but that you will be much more likely to get it. Metformin is a good drug for PCOS and should help with the high blood sugars. Your elevated cholesterol can be handled in different ways, if necessary. Aleve and Ibuprofen should not be a problem with Metformin. ...Read more

Does naproxen sodium thin the blood?

Does naproxen sodium thin the blood?

Like aspirin..: Naproxen and other nonsteroidal anti-inflammatory pills (advil, aleve (naproxen) but not tylenol) make blood platelets less sticky and so promote bleeding. They don't literally make the blood thinner, just that blood clots more slowly. They should be minimized, taken with meals, and ask doc about any special bleeding risks. ...Read more

Dr. Prescribed 500 mg. Naproxen for arthritic knee. It has raised my blood pressure to 150/90. What else can I take?

Pain/Blood Pressure: The vast majority of pain medications do not raise your blood pressure. Many other factors do contribute to elevated blood pressure, including pain, stress, anxiety, and under-treated hypertension itself. If your pain is uncontrolled, consult your doctor for additional therapies to relieve the pain. If your blood pressure is chronically elevated, see your doctor for long term medical management. ...Read more

Anticoagulant (Definition)

Anticoagulants are any of a variety of drugs which decrease the body's ability to make or sustain blood clots. They fall, generally, into two categories. Drugs like Aspirin and clopidogrel (plavix) prevent platelets from forming the initial stages of a clot. Drugs like warfarin (coumadin) and dabigatran (pradaxa) block the later process ...Read more
