Shipping Update – January 2022

Shipping times are now closer to normal. However, due to the latest outbreak of the highly contagious Omicron strain, we are anticipating some potential delays in our shipping times. We will provide updates as the situation changes.

Our normal shipping time averages 1 - 2 weeks. Shipments may now sometimes take an additional 2 – 4 weeks to arrive, depending on the source country of your order. Shipments from the United Kingdom and Canada are generally quicker than from other countries.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

We offer a shipping guarantee when you place an order with us. If your order does not arrive within 6 weeks from the date it was shipped, we will re-ship your order to you at no additional cost.

Call Center – New Hours effective January 17, 2022

Our new call center hours of operation are now 7:00 am – 7:00 pm Central Time, seven days per week.

These changes are due to staffing issues we are experiencing caused by the highly contagious Omicron variant. We anticipate that we will expand our call center hours again within the next 2 – 3 weeks.

If you are experiencing increased hold times or are calling outside of these hours, please leave us a message or send us an email and we will get back to you as soon as we can. Due to increased demand on telephone networks worldwide, you may experience some intermittent connection problems. If this happens our agents will call you back.

General Information On Grazax

Grazax is an oral pill used for treating hay fever. This is a condition which is generally caused due to a patient’s allergy to grass pollen. Its generic name is Lyophilisate, and it belongs to the therapeutic class of immunotherapy drugs. It is available as an oral pill form and needs to be taken once a day. It works by boosting immunity so that antibodies are generated against grass pollen. This drug prevents symptoms of hay fever such as a runny nose and watery, red, or itchy eyes. You should buy Grazax only if it is prescribed by your doctor, and you will need to give a positive skin prick test in order to detect an allergy to the drug (if any).

Side Effects for Grazax

One out of ten Grazax patients may complain about itching in the ears and mouth, irritation in the throat, swelling in the mouth, or sneezing. Most of these side effects are short-lived and get better as your body gets adjusted to the drug. Most negative symptoms may get triggered within minutes or hours of taking the first pill and settle down on their own within one week of beginning the treatment. Some patients may also develop conjunctivitis, cough, throat tightness, asthma, blisters in the mouth, swelling or pain in the tongue, headache, fatigue, nausea and indigestion. Some serious but rare side effects of Grazax may include swollen glands, infection in the upper airway, mouth sores, ulcers, voice changes, hoarseness, chest pain, or hot flashes. If you experience any of these symptoms, you should consult your doctor without fail.

Some patients may also develop an allergic reaction to the medicine. It can be identified by irritation or swelling in the throat, face, tongue or lips, severe dizziness, trouble breathing, and hives. If you experience any of these, you should immediately stop taking the pills and seek medical help.


You should not buy Grazax if you have an allergy to the drug or to any of its ingredients. As the pills are delicate, do not pull them out of their covering. This is a prescription medicine only and should be used only after consulting your doctor. Using them without a prescription can cause serious damage to your health. Pregnant women and lactating mothers should also not use Grazax, as it is not established as a safe medicine for such women.

Grazax Dosage

Grazax tablets need to be removed from their covering with dry fingers and have to be placed under the tongue. Keep it there for 10-15 seconds, and it will get absorbed into your body. Do not drink or eat anything for at least 5 minutes after taking the pill. It should be allowed to get absorbed on its own, and you should not swallow it with water, as with most other pills.


Some drugs may interact adversely with Grazax. Therefore, you should inform your doctor about all the prescription and over-the-counter medicines you are taking at present, including herbal products and health supplements. Based on such information, your doctor will be able to decide whether some dosage adjustments are necessary and whether Grazax is the right medicine for you or not.
