Precautions and Warnings
Valtrex can cause potential drug reactions and risks are elevated in people with impaired kidney function. Nursing mothers are advised to consult with the doctor prior to taking the medication.
Although, Valtrex is a pregnancy Category B medication, it has to be taken only if the benefits outweigh the risks to the developing fetus. It is probably safe when it is used during pregnancy, but the effects of Valtrex have not been studied in pregnant women.
Valtrex does not offer a cure for genital herpes. If you have an outbreak or if you suspect that you are going to have an outbreak you must avoid sexual contact. Always use condoms during sexual intercourse in order to prevent an outbreak or spread of genital herpes.
The effects of Valtrex have not been studied in those with multiple sex partners or in the non-heterosexual couples. Hence, it is not known if Valtrex can help prevent the spread of genital herpes in these individuals.
The effects of Valtrex in those with poorly functioning immune systems other than those with HIV, has not been studied. This also includes those individuals who may be suffering with cancer as well as those who are on immunosuppressant drugs, especially after undergoing transplant.
Valtrex should be administered as soon as symptoms are noticed. The treatment should ideally begin within three days of the appearance of symptoms – in case of genital herpes and shingles or before a cold sore is visible.
At present, there is no available information regarding the effectiveness of Valtrex if it is started after 3 days of noticing symptoms of genital herpes, shingles, or the appearance of cold sores.
When it is administered for cold sores, it should not be taken for more than a day. If it is taken for more than a day, it will not increase the effectiveness of the medication, but will instead cause side effects.
Individuals who are over 65 years of age have an increased chance of having unpleasant side effects. Hence, it is important to inform your healthcare provider who may give you a lower dosage of Valtrex.
Valtrex has resulted in a serious condition in some people and is known as thrombotic thrombocytopenic purpura or hemolytic uremic syndrome. This is a condition that involves very low RBC and platelet count.
It can cause side effects in the central nervous system where it may lead to seizures, hallucinations, confusion, and delirium. Inform your healthcare provider if you are on vitamins, herbal supplements, and prescription or non-prescription drugs.
