Evidence shows that an integrative medicine approach pairing some common drugs and nutraceuticals makes sense.

Integrative medicine is defined as “an approach to medical care that combines standard medicine with CAM (complementary and alternative medicine) practices that have shown through science to be safe and effective.”1 One area in which integrative medicine can be particularly useful is when specific nutraceuticals are used to help compensate for certain side effects caused by some prescription drugs. Due to space limitations, this article will address two common examples in detail and then list several others in a table.

Statins and Coenzyme Q10

Physicians often use statin medications as an important therapy in reducing and maintaining serum cholesterol levels in patients with hypercholesterolemia (i.e., high cholesterol levels). However, in addition to reducing cholesterol levels, statin medications also reduce the body’s production of coenzyme Q10 (CoQ10). In turn, this can lead to a myopathy marked by muscle pain in those patients prescribed a high statin dose.2

In fact, the pharmaceutical suppliers of Lipitor (Pfizer)3, Zocor (Merck)4, and Crestor (AstraZeneca)5 all state that significant decreases in circulating CoQ10 levels in patients treated with statins have been observed and that the clinical significance of a potential long-term, statin-induced deficiency of CoQ10 has not been established. This recognition is especially evident in the fact that Merck has even gone so far as to obtain two patents to combine CoQ10 with its statin drug.6

Given the potential adverse effects of statin therapy, co-administration with CoQ10 makes a great deal of medical sense. In vitro research7 has established that pretreatment with CoQ10 reduced the toxic effects of statins and may protect cells from statin-induced injuries and alleviate their side effects. Likewise, animal research8 demonstrated that CoQ10 supplementation improved metabolic parameters, liver function, and mitochondrial respiration in rats with high doses of atorvastatin and a cholesterol-rich diet. Evidence from a review of human studies9 showed a benefit in symptoms of myalgia or improvement of serum levels of CoQ10 with supplementation of 30-200 mg daily of CoQ10, with no reported risks, in patients prescribed statins. In older athletes taking statins, 200 mg of CoQ10 daily improved muscle performance as measured by time to anaerobic threshold and leg strength. Many other measures of mitochondrial function also tended to improve.10 Other research11 found that 200 mg of CoQ10 supplementation daily improved endothelial dysfunction in statin-treated type 2 diabetic patients, compared to placebo, possibly by altering local vascular oxidative stress.

Fluoxetine (Prozac) and Saffron Extract

Pharmaceutical treatments for depression are often associated with side effects. For example, common side effects of fluoxetine (e.g., Prozac) may include sexual dysfunction (decreased sex drive, erectile dysfunction, or difficulty having an orgasm).

Since saffron has shown aphrodisiac effects in some animal and human studies, a 4-week, randomized, double-blind, placebo-controlled study12 was conducted to assess the efficacy and tolerability of saffron stigma extract in treating fluoxetine-related sexual dysfunction. Thirty married male patients with major depressive disorder whose depressive symptoms had been stabilized on fluoxetine, and who had subjective complaints of sexual impairment, entered the study. The patients were randomly assigned to 30 mg/day of saffron stigma extract or placebo for 4 weeks. The International Index of Erectile Function scale was used to assess sexual function at baseline and weeks 2 and 4. Baseline characteristics, as well as baseline and final depressive symptoms scores, were similar between the two groups.

At the end of the study, saffron subjects saw significant improvements in sexual dysfunction (P = 0.009). By week 4, saffron supplementation resulted in significantly greater improvement in erectile function (P < 0.001), intercourse satisfaction (P = 0.001), and total sexual health scores (P < 0.001) compared to the placebo group. Nine patients (60%) in the saffron group and one patient (7%) in the placebo group achieved normal erectile function (score > 25 on erectile function domain) at the end of the study (P = 0.005). Frequency of side effects was similar between the two groups. In conclusion, saffron is a tolerable and efficacious treatment for fluoxetine-related erectile dysfunction.

A similar randomized, double-blind, placebo-controlled study13 was conducted with 34 women with major depression who were stabilized on 40 mg/day of fluoxetine for a minimum of 6 weeks and who had experienced subjective feeling of sexual dysfunction. The patients were randomly assigned to saffron (30 mg/daily) or placebo for 4 weeks. Measurement was performed at baseline, week 2, and week 4 using the Female Sexual Function Index (FSFI).

At the end of the fourth week, patients in the saffron group had experienced significantly more improvement in total FSFI (p < 0.001), arousal (p = 0.028), lubrication (p = 0.035), and pain (p = 0.016) domains. Frequency of side effects was similar between the two groups. In conclusion, it seems saffron may safely and effectively improve some of the fluoxetine-induced sexual problems, including arousal, lubrication, and pain.

Other Medications and Nutraceutical Relationships

The following information comes from previous research that I published14:


Clearly, there are far more nutraceuticals that can be used to help compensate for certain side effects caused by other prescription drugs than can be addressed in the scope of this article. Nevertheless, the examples given—especially the relationship between statins and CoQ10—represent an integrative medicine approach to some common drugs and nutraceuticals.
