contraindications
I. possible drug interactions:
- Sympathomimetics eg: MAOIs (isocarboxazid, linezolid, methylene blue, moclobemide,
phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine, chlorgyline, nialamide, pargyline,
befloxatone, brofaromine, moclobemide)
If taken within 2 weeks before, during, and after treatment with this medication,
in some cases a serious and possibly life threatening drug interaction may occur.
Very high blood pressure can occour. DO NOT COMBINE ANY MAOI WITH METHAMPHETAMINE!!
- Antidepressants (venlafaxine)
Can cause dangerous fluctuations in blood pressure and possible serotonin syndrome.
- Tricyclic antidepressants (amitriptyline, amoxapine, clomipramine, doxepin, imipramine, desipramine,
nortriptyline, protriptyline, trimipramine)
Taking methamphetime with tricyclics can change the way the brain reacts to methamphetamine,
possibly causing more side effects.
- SSRIs (fluoxetine, citalopram, fluvoxamine, paroxetine, sertraline)
Serotonin reuptake inhibitors may potentiate the pharmacologic response to sympathomimetic agents.
- NARIs/Noradrenaline Reuptake Inhibitors (mianserin)
Stimulant effects felt by methamphetamine are almost completely blocked by NARIs.
- Insulin
If taken with methamphetamine, insulin can increase your risk of low blood sugar
(hypoglycemia) because you may eat less while taking methamphetamine (it is an appetite
suppressant).
- Medications for high blood pressure (guanethidine)
Since psychotstimulants can increase blood pressure, they may counteract the effectiveness
of antihypertensives
- Beta blockers (atenolol)
- Medications that affect the acid level of the urine (sodium bicarbonate, acetazolamide)
Alkalinization of the urine can decrease the renal elimination of methamphetamines. Methamphetamine
effects may be prolonged, and the risk of toxicity may be increased.
- Other stimulant medications (e.g., methylphenidate, lisdexamfetamine)
Combining other stimulants with methamphetamine may decrease the effects of methamphetamine.
- Phenothiazines (chlorpromazine, thioridazine, fluphenazine, perphenazine, promethazine,
trifluoperazine)
If taken with methamphetamine, this may decrease the effectiveness of methamphetamine.
- Cough & Cold products (dextromethorpan)
Mixing cold medicines with methamphetamine may cause blood pressure to become
dangerously high or lead to irregular heart rythyms
- Isoniazid (INH)
- Ioflupane eg: dopamine transporter bin
Drugs that bind to the dopamine transporter with high affinity may interfere with the
image obtained using ioflupane I-123, which also binds to the dopamine transporter.
- SNRIs (venlafaxine)
Possibly causes seizures when combined with methamphetamine.
- Serotonergics (MDMA, St. Johns Wort, tramadol, pethidine, triptans)
These drugs have the potential to produce symptoms of serotonin toxicity
- Antipsychotics (colazapine)
These drugs antagonize the effects of dopamine at D2 receptor. Using methamphetamine
with any of these drugs can greatly reduce the efficacy of each drug. May also induce
a meth-related psychosis or psychotic symptoms, or antipsychotic-induced acute dystonias.
II. Pre-existing Conditions that should not be mixed with Methamphetamine
- Allergy to methamphetamine hydrochloride, Desoxyn, or any inactive component in the drug
- Heart conditions including heart disease, atherosclerosis, congestive heart failure, recent heart
attack, certain irregular heart rhythyms (arrhythmias)
- Have moderate to severe hypertension (high blood pressure)
- Severe agitation
- Overactive thyroid (hyperthyroidism)
- Glaucoma
- Have used a monoamine oxidase inhibitor (MAOI) within fourteen days
- Tourette's Syndrome (methamphetamine can exacerbate tics)
- Diabetes
- Pregnant or could be pregnant, or breastfeeding (methamphetamine is passed through breast milk and may effect an unborn baby resulting in low birth
weight)
I am so sorry it took me so long, I was having trouble "working" on my vacation

Thanks for being patient with me. This is kind of a rough draft, there's more things I will be adding, but I just wanted to get this to you so you had something. Any questions or comments or things I can fix/improve, please let me know! Also, in the very very near future, I plan to attack the ROA section.
