The Prescription Pad Is Not a Finish Line

Why maintenance medicine does not end when the tablets do

Thirty tablets is not a treatment. It is thirty days.

I had this conversation so many times that I can tell how it will go before it begins. A patient comes back after six months, or a year, or after one bad morning that frightened them, and the blood pressure is higher than it was the day we met. The medicine is not in the bag. When I ask why, the answer is almost always one of four.

They felt better, so they thought they no longer needed it. They finished the number written on the pad. Someone warned them these tablets are hard on the kidneys. Or the neighbor said hers was better, and cheaper besides.

None of these is true.

What the number on the pad actually means

The number of tablets I write is not a course of cure. It is a supply that runs until I want to see you again.

If I write thirty, I am saying: come back in thirty days. I am not saying your hypertension will be gone in thirty days. The tablet count is a calendar. It is how the pharmacy and I agree on when you and I will next sit down together.

That follow-up is the entire point, because it is where a decision gets made. Sometimes I continue what you are taking. Sometimes I lower the dose because you have been feeling faint in the afternoons. Sometimes I add a second drug at a small dose instead of pushing the first one higher. Sometimes I stop something altogether. I cannot make any of those decisions about a patient who is not in front of me.

Patient follow-ups are very important. This is why it’s free in my clinic for senior citizens. Free consultation and follow-up for PWDs.

So, when the tablets run out, that is not the end of the treatment. That is the appointment.

Why it is called maintenance

The word is doing honest work. Maintenance medicine maintains.

It holds a blood pressure where it belongs. It keeps a cholesterol down, a blood sugar steady, a thyroid in the range the body can use. What it does not do is repair the reason the number went wrong in the first place. Hypertension is not an infection. This is not a seven-day course that ends with the problem gone. The drug works while it is in you, and when it leaves, the pressure goes back to doing what your arteries were always going to do.

Which is why I felt better is the most expensive sentence in my clinic. You felt better because the medicine was working. High blood pressure has almost no symptoms of its own — that is the cruelty of it. A person can walk around for years at 160/100 feeling perfectly well, while the damage collects quietly in the kidneys, the eyes, the small vessels of the brain, and then announces itself all at once on an ordinary Tuesday. Feeling well is not an evidence. Very often it is the medicine's own success being used as the argument against it.

About the kidneys

This is the fear I hear most, and it deserves a straight answer rather than a dismissal.

Medicines given to adults have been tested for years before anyone writes them on a pad — in the laboratory, then in small groups of people, then in large ones, watched specifically for the kind of harm this fear is about. Kidney and liver functions are among the things measured. The testing is the reason the drug is on the pad at all.

What I actually see damaging kidneys, far more often, is years of blood pressure and blood sugar left untreated. In that quarrel, the medicine is not the threat to the kidney. The disease is.

Your neighbor is not you

She means well. But she is not your doctor, and more to the point, she is not you.

Two people with the same reading on the same machine will need entirely different drugs. It depends on age, on how the kidneys are working, on whether there is asthma, on pregnancy, on what else is already being swallowed every morning and what it will collide with. A tablet that is exactly right for your neighbor can drop your pressure too low, or stir up a condition she does not happen to have.

Borrowed medicine is a guess made with somebody else's body.

What I am asking

Take it the way it was written. When the tablets are nearly gone, come back — not when you feel unwell, but when the supply is ending. Bring the old prescriptions, the lab results you prescribed to yourself, all of them, including whatever a relative pressed into your hand, or prescriptions made by another for second opinion. And if something about the medicine is bothering you, the cough, the dizziness, the cost, please say so out loud, because there is nearly always another way to do it. I would much rather change your prescription than have you quietly abandon it.

If you have already stopped, come anyway. Nobody is going to scold you.

The prescription is not a sentence to be served. It is a conversation we agree to keep having.
