Safety and side effects: how risk is checked and managed

When to skip messaging and call 911

HealifyMD is not an emergency service, and some symptoms cannot wait for a reply. Call 911 or go to the nearest emergency department if you notice any of the following, whatever treatment you are on.

• Chest pain, pressure or a racing, irregular heartbeat
• Trouble breathing, or swelling of the face, lips or throat
• Sudden weakness, numbness, confusion or trouble speaking
• Sudden loss of vision or hearing
• Severe abdominal pain, especially pain that spreads to the back or comes with vomiting
• Pain, swelling and warmth in one leg, or sudden shortness of breath
• An erection lasting longer than four hours
• Thoughts of harming yourself

Why we ask about every medication and supplement

Drug interactions are one of the most preventable sources of harm. A clear example is tadalafil: MedlinePlus advises that people taking nitrates, including the recreational drugs called poppers, should generally not take it because the combination can cause a dangerous drop in blood pressure. Other interactions are subtler, such as medications that change blood sugar or how another drug is absorbed.

Supplements count too. Some can interact with prescriptions, and others can distort lab results. List everything, including vitamins, herbal products, over-the-counter pain relievers, alcohol and recreational drugs. Your clinician is not judging; they need the full picture to keep you safe.

What compounded means for safety

Many HealifyMD prescriptions are filled by compounding pharmacies, which prepare a medication for an individual patient. The FDA states plainly that compounded drugs are not FDA-approved, and it does not verify their safety, effectiveness or quality before they are dispensed. Traditional compounding pharmacies are overseen mainly by state boards of pharmacy.

That means results from clinical trials of branded products, such as Wegovy or Zepbound, do not automatically apply to compounded versions. Your clinician should tell you when a prescription is compounded, and you are always free to ask whether an FDA-approved option exists for your situation.

How monitoring differs by treatment

Monitoring is matched to the specific risks of each medicine. A few examples show how different it can look.

• Testosterone therapy: hematocrit and PSA are checked before and during treatment, according to American Urological Association guidance.
• Metformin: long-term use can lower vitamin B12 absorption, so B12 may be checked periodically.
• GLP-1 medications: your clinician watches for stomach symptoms, dehydration, gallbladder and pancreas warning signs.
• Rapamycin (sirolimus): because it can raise infection risk, your clinician orders lab tests and reviews vaccines and infections with you.

Pregnancy, breastfeeding and fertility plans

Many of the medications we prescribe are not appropriate during pregnancy or breastfeeding, and some affect fertility. GLP-1 labels, for example, advise stopping semaglutide about two months before a planned pregnancy, and testosterone therapy can suppress sperm production. Tell your clinician right away if you are pregnant, could be pregnant or are trying to conceive.

A closer look at beta blockers for performance nerves

Propranolol and similar beta blockers are sometimes prescribed for situational performance anxiety, such as a big presentation. They blunt the physical surge of adrenaline, including a pounding heart and shaky hands, but they do not quiet anxious thoughts and are not a treatment for an anxiety disorder.

They are also not right for everyone. People with asthma, a very slow resting heart rate, low blood pressure, certain heart conditions or diabetes treated with insulin need extra caution or a different approach, because beta blockers can tighten airways and mask the warning signs of low blood sugar. If you take a beta blocker every day, do not stop it suddenly without a plan from your prescriber.

Problems telehealth is not built to handle

Online care works well for conditions that can be assessed through history, conversation and lab results. It is not a substitute for a physical exam when one is needed, such as a new lump, unexplained bleeding, a joint injury or chest symptoms. If your clinician thinks you need to be seen in person, that recommendation is part of keeping you safe, not a brush-off.

We also encourage you to keep a primary care doctor. Sharing your HealifyMD plan with them means everyone involved in your care is working from the same medication list and the same lab results.

How to report a side effect

Message your care team through your patient account or email support@healifymd.com with what you noticed, when it started and what you were doing. Do not stop or change a dose on your own unless your clinician tells you to, because stopping some medications abruptly can cause rebound symptoms. You can also report serious reactions to the FDA through its MedWatch program.
