Coming back to: Official shortage notices and what they authorise posts 31–44

post #30 is right about the mechanism and I think understates the practical bit.

International supply chains: a shortage in one country does not mean shortage in another. That is why ordering from multiple suppliers before a shortage gets bad is prudent if you can.

Communication from suppliers: a supplier having supply problems usually communicates them. If a supplier goes silent, that is itself information.

Resuming after a gap: after a gap of days or a few weeks, most people resume at the dose they were on when they stopped. Gaps of months might require retitration discussion with a clinician.

I read post #32 twice before replying, because I had assumed the opposite.

Shortage predictions: regulators and suppliers issue shortage alerts before they become acute. Checking the regulatory website for shortages gives you advance notice.

Dose hold versus tapering: if a temporary shortage forces a gap, holding your dose and resuming when supply returns is different from gradually tapering. The two are different decisions.

Compounding during shortages: some jurisdictions allow pharmacy compounding when a marketed product is in shortage. That permission is jurisdiction-specific and time-limited (usually for the duration of the shortage).

Picking up post #34: that is the part I would want checked first.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

Coming back to post #36, because the follow-up matters more than the original answer.

Allocation and rationing: during severe shortages, suppliers might ration allocation to prescribers. Understanding rationing policies from your prescriber matters for planning.

Resuming after a gap: after a gap of days or a few weeks, most people resume at the dose they were on when they stopped. Gaps of months might require retitration discussion with a clinician.

Worth separating two things that post #36 runs together.

Worth separating two things that post #37 runs together.

Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.

The correction was fair and I had been repeating something I had not checked carefully enough.

International supply chains: a shortage in one country does not mean shortage in another. That is why ordering from multiple suppliers before a shortage gets bad is prudent if you can.

Dose hold versus tapering: if a temporary shortage forces a gap, holding your dose and resuming when supply returns is different from gradually tapering. The two are different decisions.

Managing an unplanned gap: if a shortage causes a gap in treatment, the questions are how long the gap will be and how that affects your condition. Discussing with your clinician is prudent if the gap is weeks or longer.
