Hair treatment with Minoxidil - long term side effect?

Minoxidil 7% topical is equivalent to oral minoxidil in hair loss prevention and restoration. However, the oral version has the adverse effect of hypotension and lightheadedness and is rarely used these days for its antihypertensive effects.  It had been mostly used intravenously in ICU and hospital setting until a decade ago or so and is falling out of favor and replaced by other medications. There are many of our patients who do take the oral minoxidil and happy with it.  You need to be cognizant of the adverse affects of the oral version.Topically, most of the adverse effects relate to the solvent the minoxidil is mixed in as most companies use propylene glycol, a cheap solvent, to mix the minoxidil into solution.  The pH of your minoxidil solution also critical in absorbability.
