I found a pill called Ismelin.. what is it for?

Question

This pill was found amongst other pharmaceuticals, in the possession of someone who would intend to abuse it. Does Ismelin (imprinted CIBA on one side, 3 on the other, small white pill) cause intoxicating effects? If so, what are they?

Answer 1

Ismelin is an utterly obsolete medication for high blood pressure.

It's so old that I don't even recall prescribing it... I didn't know that branded Ismelin was even produced anymore.

One pill? That's not going to do anything much in terms of intoxicating effects. I don't recall that Ismelin had any major psychotropic activity, but it's been every bit of twenty years since I've heard the name, maybe more.

Answer 2

ISNELIN - is the brand name of Guanethidine. Guanethidine lowers blood pressure by decreasing the levels of certain chemicals in the blood. This allows your blood vessels (veins and arteries) to relax (widen). Guanethidine is used to treat hypertension (high blood pressure). Guanethidine is also used to treat high blood pressure in the kidneys.

Guanethidine may also be used for purposes other than those listed in this medication guide.

Guanethidine is available with a prescription under the brand name Ismelin. Other brand or generic formulations may also be available. Ask your pharmacist any questions you have about this medication, especially if it is new to you.

* Ismelin 10 mg--round, pale-yellow, scored tablets
* Ismelin 25 mg--round, white, scored tablets

Side effects of this medication are as under and you should stop taking guanethidine and seek emergency medical attention or contact your doctor immediately:

* an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);
* irregular heartbeats;
* heart failure (shortness of breath, swelling of ankles or legs, sudden weight gain of 5 pounds or more); or
