Shingrix is a shingles vaccine that will offer greater protection against shingles than our current vaccine, Zostavax. One of its advantages is that it is extremely effective regardless of the age it is administered, offering over 90% protection in those over age 70. Effectiveness of our current vaccine, Zostavax, decreases significantly when given to adults over age 70.
Shingrix will require two injections given 2 months apart. Unlike the live vaccine, Zostavax, Shingrix isn’t a live vaccine and therefore can be given to patients who are taking immunosuppressant treatment. However, recipients may experience more redness and and skin irritation from Shingrix as it is a very immunogenic vaccine. Therefore we are uncertain if could cause a flare in people with an auto-immune disease.
We will keep you informed of all information once this vaccine is released. We are not yet sure of how the provincial government will respond in offering coverage of this vaccine. Currently Zostavax is provided through public health to those between 65-70 years of age.
For more information on this vaccine or any other medications, please speak to your healthcare provider.

It is well known that even 1/2 a grapefruit or one glass of juice can reduce an enzyme called cytochrome P450 (CYP 450) by 50% for up to 24 hours. This is important because some medications such as atorvastatin, amlodipine, carbamazepine and one of our newest medications for rheumatoid arthritis, tofacitinib (Xeljanz) need this enzyme to be eliminated from the body. If grapefruit juice is combined with these medications, they could accumulate in the body increasing the potential for adverse effects. Therefore, it is recommended that grapefruit not be ingested with medications requiring this enzyme for processing.
This week, we’re pleased to be bringing you information on an upcoming FREE forum that our pharmacist, Carolyn Whiskin, will be speaking at. The Ontario Pain Foundation regularly hosts these sorts of forums on a wide range of topics surrounding pain management.
