July 2023 Archive — Practical Notes on Drugs, Supplements and Research

This month’s posts focus on real-world issues: how certain lipids and drugs affect chronic disease, what to watch for with common supplements, and recent findings that change care. Below I sum up the main points and practical takeaways you can use right away.

Supplements: promises and precautions

Two plant-based supplements stood out: white hellebore and Dendrobium. Both show interesting properties in early research — anti-inflammatory and antimicrobial actions for white hellebore, energy, digestion and immune support for Dendrobium. That sounds good, but research is still limited. If you’re thinking of trying these, check product purity and dose, start low, and tell your clinician. Herbal supplements can interact with prescription meds and sometimes contain impurities.

Quick tip: pick brands with third-party testing and avoid high-dose blends unless a provider recommends them.

Medications: mechanism, risks, and interactions

Several posts explain how common drugs work and why that matters. Cyclobenzaprine HCL relaxes muscles by acting on the brainstem — it calms the reflexes that cause spasms rather than acting on muscle fibers directly. Expect drowsiness and avoid heavy machinery until you know how it affects you.

Isosorbide dinitrate, used for angina, can dangerously interact with erectile dysfunction meds and some migraine or antidepressant drugs, causing severe drops in blood pressure. Always list every medication, supplement, and OTC drug to your provider before starting nitrates.

Apixaban is a useful blood thinner, but surgery needs careful planning. The post explains timing: stopping it before procedures reduces bleeding risk, while restarting too soon raises bleeding risk and waiting too long raises clot risk. Talk with your surgeon and prescribing doctor to set exact stop-and-restart windows based on your bleeding risk and the surgery type.

Short practical checklist for blood thinners before surgery: confirm the exact stop time with your team, plan perioperative bridging only if recommended, and arrange clear follow-up for restarting therapy.

Another post explored LDL’s role in diabetes. When LDL rises, so does cardiovascular risk for people with diabetes. High LDL makes artery plaques worse and complicates diabetes care. Managing LDL through lifestyle and, when needed, statins or other lipid-lowering drugs cuts heart risk. Don’t ignore cholesterol because glucose control alone isn’t enough.

Finally, dermatitis herpetiformis — a skin condition tied to gluten sensitivity — shows up as itchy blisters and is linked to IgA deposits in the skin. The strongest practical step is a strict gluten-free diet; medications like dapsone can relieve symptoms while dietary changes take effect. If you have persistent itchy rashes and gut symptoms, ask about testing for gluten-related disorders.
