[[Withdrawal|Withdrawal symptoms]] may occur after ceasing usage abruptly following a few weeks or longer of steady dosing and the severity of the withdrawal symptoms increase the longer one uses the substance. Withdrawal symptoms can generally be minimized or avoided by tapering the dose slowly and carefully monitoring for symptoms. Symptoms vary depending on the specific substance and can include (but are not limited to) increased heart rate and/or blood pressure, irritability, [[anxiety]], [[nausea]], headaches, tremors, insomnia, depression, sensitivity to pain, hallucinations, seizures, and death. | [[Withdrawal|Withdrawal symptoms]] may occur after ceasing usage abruptly following a few weeks or longer of steady dosing and the severity of the withdrawal symptoms increase the longer one uses the substance.

To taper successfully, users should decrease their dose each day or at least stay at the same dosage; however, if withdrawal symptoms are intolerable, one may be tapering too quickly and should slightly increase the dosage until withdrawal symptoms become minimal. Generally, the longer one has been on the drug, the longer the taper should be.<ref>http://www.hrpub.org/download/201310/app.2013.010202.pdf</ref> Slow tapers will result in less withdrawal symptoms than faster tapers. It may be helpful for users to stay at the same dosage for several days/weeks and then decrease amount slowly. | To [[taper]] successfully, users should decrease their dose each day or at least stay at the same dosage; however, if withdrawal symptoms are intolerable, one may be tapering too quickly and should slightly increase the dosage until withdrawal symptoms become minimal.

In comparison to the [[cold turkey | In comparison to the [[cold turkey]], tapering can take more self-discipline. It is recommended that users give the drug to someone trustworthy and have them only give the dosage listed on the pre-planned tapering schedule daily. In some cases, however, the cold turkey method can be preferred by individuals or even more effective than tapering for some substances. For example, studies show that the cold turkey method of [[tobacco]] cessation is more likely to be effective for individuals looking to quit smoking.<ref>{{cite journal | vauthors=((Lindson-Hawley, N.)), ((Banting, M.)), ((West, R.)), ((Michie, S.)), ((Shinkins, B.)), ((Aveyard, P.)) | journal=Annals of Internal Medicine | title=Gradual Versus Abrupt Smoking Cessation | volume=164 | issue=9 | pages=585–592 | date=3 May 2016 | url=https://www.acpjournals.org/doi/10.7326/M14-2805 | issn=0003-4819 | doi=10.7326/M14-2805}}</ref> | ||
Substances with long half-lives (like [[diazepam]]) are preferable to shorter-lasting ones (including [[alprazolam]] and [[lorazepam]]) because the latter are eliminated fairly quickly, resulting in its blood concentrations fluctuating instead of smoothly declining gradually. Tapering off of substances with short half-lives generally require taking multiple dosages per day and users will likely experience withdrawal symptoms between doses. Diazepam is the most commonly used drug for tapering off of [[benzodiazepines]] or [[alcohol]] because it has a half-life of 200 hours.<ref name="benzo"> | Substances with long half-lives (like [[diazepam]]) are preferable to shorter-lasting ones (including [[alprazolam]] and [[lorazepam]]) because the latter are eliminated fairly quickly, resulting in its blood concentrations fluctuating instead of smoothly declining gradually.

As an example of a slow withdrawal schedule, a user taking 40mg diazepam a day (or the equivalent) could reduce their daily dosage by 2mg every one or two weeks until a dosage of 20mg diazepam per day is reached; this would take 10 to 20 weeks. Starting from 20mg diazepam per day, reducing the amount to 1mg per day every week or two may be preferable, taking a total of 20 to 40 weeks.<ref name="benzo"></ref> Some users may prefer to reduce faster and some may go even slower. | As an example of a slow withdrawal schedule, a user taking 40mg diazepam a day (or the equivalent) could reduce their daily dosage by 2mg every one or two weeks until a dosage of 20mg diazepam per day is reached; this would take 10 to 20 weeks.
