Taking. 25mg of Xanax (alprazolam) once or sometimes twice a day. Helps take off the edge of worriness for me. Is that dose so small to even help?

CBT?: Well - if it takes the edge off than it is working. It is fairly easy to develop tolerance to benzodiazapines. Have you considered cognitive behavioral therapy?

How long/how many days does it take for 0.25 mg doses of Xanax (alprazolam) to start taking affect and make one feel relaxed, calm, and less anxious?

Xanax (alprazolam) not working: The benzodiazepine (e.g. Xanax) naive patient should feel the effect within the hour. Individuals are unique and depending on one's pharmacogenetics/liver metabolism of medications, the medication may work for some but as well for others. The prescribing physician should be informed. More importantly, non-medicinal modalities & non-habit forming medications should be attempted first.

Drug info states w/d from Xanax (alprazolam) can occur after short term low doses even one, true? Unclear on why I feel symptoms now, that never had before took it

Drug info states w/d from Xanax (alprazolam) can occur after short term low doses even one, true? Unclear on why I feel symptoms now, that never had before took it

Xanax (alprazolam) and anxiety: You would not be in withdrawal from xanax (alprazolam) after only 1 dose. However, it's possible to have a paradoxical agitated (rather than relaxed) reaction. If you've been taking xanax (alprazolam) regularly and then stop, you can have withdrawal symptoms that overlap with the symptoms you might have from anxiety itself. Extreme anxiety can also be part of a withdrawal syndrome.

Can st. Johns wort be taken with one dose of. 025mg xanax (alprazolam)?

Can st. Johns wort be taken with one dose of. 025mg xanax (alprazolam)?

Would not use: St. John's wort can induce the liver enzymes needed to metabolize xanax (alprazolam) and prozac, possibly making them less effective. Why would you want to take st. John's wort when you're already on Prozac & xanax (alprazolam) (according to your additional patient information)?

John's wort has similar serotonin reuptake-inhibiting action to prozac, leading to adverse effects.

Does using 0.25mg of Xanax (alprazolam) two times per week cause prolactin levels to rise? Is it possible such a small dose could do that?

Does using 0.25mg of Xanax (alprazolam) two times per week cause prolactin levels to rise? Is it possible such a small dose could do that?

Rare: Xanax, (alprazolam) very rarely can cause prolactin elevation and if you are prone to it, the frequency or dose may not matter. Most common psychiatric medications to cause this are antipsychotics by blocking Dopamine which helps control prolactin level. See your doctor and rule out other causes as well.

I have been taking 1.5 mg of Xanax (alprazolam) a day in one dose. Is taking 2mgof Ativan (trying to switch meds) ok instead of Xanax (alprazolam)?

May be better: Ativan is slightly longer half life than Xanax (alprazolam) and should be smoother acting however Tranxene is a better choice and is longer acting and less addictive.

I'm on a low dose of xanax 0.25mg. And it says to take 1-2 a day if needed. Can I take an extra one? I feel it doesn't last long even when I take two.

Follow Dr's directon: Xanax is out of your system very quickly. It can be highly addictive, as well. It is intended to be used for very short periods of time for extremely stressful temporary situations. If your stress or anxiety is ongoing and especially if you need more than 2 a day, you may need a different kind of medication. Make an appointment with your doctor and follow her insructions.

I have been taking Xanax for several years. A low dose of 0.25 mg. My BP Has been very low 80/60 and I have fainted at times. Is the Xanax causing It?

I have been taking Xanax for several years. A low dose of 0.25 mg. My BP Has been very low 80/60 and I have fainted at times. Is the Xanax causing It?

Possible, ask DR: Yes, both hypotension (low blood pressure) and syncope (fainting) are possible side effects of Xanax. You are taking a very low dose, and you do not specify why you have been taking this for years. Anxiety? Insomnia? Check with your prescribing Dr about withdrawing slowly off this drug. Consider nondrug solutions like CBT psychotherapy from an experienced psychologist for anxiety or insomnia.

I have been on Xanax (alprazolam) 8-10mgs daily. 2mgs every 4-6 hours. Started a taper, what's the safest rate I can reduce my dose. So far taken. 5mgs off daily.

Very slow taper: Xanax (alprazolam) is a difficult medication to get off of and the higher the dose and the longer the time used will determine to a large degree what is a safe taper. You should not be reducing daily. You should not try to come off of this medication without being under the supervision of a physician who is knowledgeable in taking patients off this kind of medication. Withdrawal can be severe. See MD.
